What are the best places to go solar?
Getting the most out of your solar speculation is not just about finding the sunniest places in the United States. Other similarly imperative elements when choosing to go solar are the cost of power where you live, and additionally the accessible money related motivators. As should be obvious from our guide of private power rates in the U.S., the cost of power changes the nation over, making solar energy more alluring in areas with higher rates. Also, a few states and regions are substantially more liberal than others with regards to helping property holders put solar boards on their rooftop. These components are essential when attempting to decide the arrival on your venture.
We mull over the level of solar radiation, the cost of power and the government speculation assess credit of 30% (which was as of late stretched out) in our intelligent lattice equality outline the United States. You can utilize it to see where solar energy bodes well.
Initial, a Quick Look Across the Pond
Did you realize that the nation with the most solar boards on Earth is additionally one of the nations with the least levels of solar radiation? In spite of getting just around 66% the solar radiation of the United States, Germany has two fold the introduced solar limit (38 GW, contrasted with 19 GW as indicated by the Global Market Outlook for Solar Power 2015-2019). So what makes Germany such a problem area for solar? For one, the cost of power in Germany is more than 40 pennies for every KWh, contrasted with a normal of 12 pennies for every kWh in the United States. Besides, the cost per watt of introduced solar boards in Germany is about a large portion of the value that it is in the U.S. (the normal cost for a private solar framework in the U.S. is about $4/W, in spite of the fact that it differs extensively from state to state, with California revealing a cost of about $5/W).
You can perceive how different nations stack up as far as the solar esteem list with our worldwide guide for the best places to go solar on the planet.
The Top U.S. States for Solar Energy
We should investigate the United States now. The Solar Energy Industries Association (SEIA) reports that as of the second quarter of 2015, the best state regarding the total introduced solar PV limit is California, with more than 11 GW. This does not come as an awesome suprise given the generally high solar radiation this state gets, yet its moderately high cost of power additionally assumes a part (the normal retail rate for private power in California is almost 17 pennies for every kWh). While California does rank number 1 not all of its counties and cities are equal. Norther california tends to have a more cloud cover which effects solar output. Southern california on the other hand with counties like Los Angeles, Orange County, San Diego County, are prime locations. Going Solar in Laguna Hills, La Joya, Newport Beach, Downey, and other cities is actually becoming quite the trend. After California, we have Arizona with more than 2 GW and New Jersey with around 1.5 GW. While there are numerous different states that get more solar radiation than New Jersey, it is the mix of liberal solar impetuses and the generally high power rate (about 16 pennies for every kWh) that makes New Jersey the third state for introduced solar limit.
North Carolina, Nevada, Massachusetts, New York, Hawaii, Colorado, and Texas finish the rundown of best ten states for aggregate introduced limit. Florida, which numbers numerous sunny areas, is not even in the main ten.

I think we can all agree that solar inverters, or microinverters, are the most crucial parts of any solar power system, right?
For anyone who knows their stuff when it comes to solar power systems, solar inverters are widely considered to be the brains of the project as it serves as the gateway between the photovoltaic (PV) system and the energy off-taker. But what exactly does a solar inverter do and what advantages do they bring to your solar power system? This article will discuss the know-how of a solar inverter.

How solar inverters work
Basics of solar power
Before getting into the greens of what a solar inverter is, it's important to understand first what solar power does. It is, of course, the harnessing of solar energy to be transformed into power, e.g. electricity, for consumer consumption, and is widely considered to be the cleanest, most sustainable source of renewable energy. Alongside wind, solar power is the alternative to fossil fuels, which have been found to be a top cause of global warming.
What is a solar inverter?
In essence, an inverter’s basic function is to “invert” the direct current (DC) output into alternating current (AC). The yield from a few solar inverters is joined and frequently nourished to the electrical matrix. Solar inverters stand out from traditional string and focal solar inverters, which are associated with various solar modules or boards of the PV framework.
Solar inverters have a few points of interest over customary inverters. The principle advantage is that little measures of shading, flotsam, and jetsam or snow lines on any one solar module, or even a total module disappointment, don't excessively lessen the yield of the whole cluster. Each microinverter harvests ideal power by performing maximum power point tracking (MPPT) for its associated module. Simplicity in framework configuration, low amperage wires, disentangled stock administration, and built-in security are just some of the elements presented with the inverter arrangement.
Solar boards deliver current at a voltage that depends on the module outline and lighting conditions. Present-day modules that use 6-inch cells often contain 60 cells and provide an ostensible 30 V. For transformation into AC, boards might be associated in arrangement to create a large solitary board with an ostensible rating of 300 to 600 VDC. The power at that point races to an inverter, which changes over it into standard AC voltage, ordinarily 230 VAC/50 Hz or 240 VAC/60 Hz.
Disadvantages of a solar inverter
While solar inverters are indeed considered to be an important part of any solar power system, they do incorporate a higher starting hardware cost per crest watt than the same energy of a focal inverter since every inverter should be introduced nearby a board (typically on a rooftop). This likewise makes them harder to keep up and all the more expensive to expel and supplant (O&M). A few producers have tended to these issues with boards with worked in solar inverters.
Another issue, however minor, is that string inverters are accessible in a restricted choice of energy evaluations. This implies that a surrendered cluster regularly sizes the inverter to the following biggest model over the rating of the board exhibit. For example, a 10-board cluster of 2300W may need to utilize a 2500W or even 3000W inverter, paying for transformation capacity it can't use.
The principle issue with the "string inverter" approach is the series of boards go about as though it were a single bigger board with a maximum current rating equal to the poorest entertainer in the string. For instance, on the off chance that one board in a line has 5% higher resistance because of a minor assembling imperfection, the whole series ensures a 5% execution misfortune.
On the off chance that the client initially obtained a 2500W inverter for their 2300W of boards, they can't include even a solitary board without overdriving the inverter. In any case, this overmeasuring is viewed as normal practice in the present business (now and again as high as 20 percent over inverter nameplate rating) to represent module corruption, higher execution amid winter months or to accomplish higher offer back to the utility.
‘Christmas lights’ impact
This circumstance is dynamic. If a board is shaded its yield drops drastically, influencing the yield of the string, regardless of the possibility that other boards are not shaded. Indeed, even slight changes in the introduction can cause yield misfortune in this mold. In the business, this is known as the "Christmas lights impact," alluding to the way a whole series of arrangement hung Christmas tree lights will fizzle if one globule fails.
However, this impact is not by any stretch precise and disregards the unpredictable connection between present-day string inverter greatest power point following and even module sidestep diodes. Shade thinks about by major micro inverter, and DC enhancer organizations indicate little yearly picks up in light, medium and substantial shaded conditions -2 percent, 5 percent and 8 percent separately finished a more seasoned string inverter.
Greatest power direct
Moreover, the productivity of a board's yield is unequivocally influenced by the heap the inverter puts on it. To boost generation, inverters utilize a method called “greatest power direct” by altering the connected load. In any case, similar issues that make yield change from board to board, influence the best possible amount that the MPPT framework ought to apply.
If a single board works at an alternate point, a string inverter can just observe the general change and moves the MPPT point to coordinate. This outcome in not only misfortunes from the shadowed board, but rather other boards as well. Shading of as meager as 9% of the surface of a cluster can, in a few conditions, diminish broad framework power as much as 54%. However, as expressed over, these yearly yield misfortunes are little, and more up to date innovations enable some string inverters to fundamentally lessen the impacts of partial shading.
Different difficulties related with unified inverters incorporate the space required to find the gadget, and additionally warm dispersal prerequisites. Vast focal inverters are regularly effectively cooled. Cooling fans make a commotion, so the area of the inverter in respect to workplaces and possessed regions must be considered. What's more, since cooling fans have moving parts, soil, tidy, and dampness can adversely influence their execution after some time. String inverters are calmer yet may create a murmuring commotion in the late evening when inverter control is small.

As climate change takes center stage among the planet’s environmental problems, wouldn’t it be great to be able to invest in renewable sources of energy?
If yes, then solar power might just be for you, as it’s widely considered to be the cleanest, most efficient renewable energy source. In principle, it’s simple: you harness sunlight to create energy. But how does solar power work? This article will discuss just how electricity is generated from solar power and what its advantages are.

How does solar power work
Solar power isn't a newly created idea to help reduce carbon dioxide emissions. The first solar power research began in the early 1950s. The 1980s and 1990s saw several breakthroughs in solar power generation. However, because of the increasing threat of global warming, solar power is quickly becoming a viable source of household electricity around the world.
What is solar power
What began as an environmentally sound move by people who are concerned about the environment is becoming mainstream practice. In fact, the solar power industry in the United States is booming, perhaps because of the increasing recognition of its benefits toward a more sustainable environmental lifestyle. Researchers have found that nearly 260,000 Americans work in solar—or more than double the number in 2012—in more than 9,000 companies in every US state. This increase has also led to a rise in solar power’s share in electricity generation to more than a third. Meanwhile, the cost of installing solar systems have dropped drastically since 2010.
The numbers are nothing but testament to the effectiveness and efficiency of solar power as the best solution among renewable energy sources. With its virtually unlimited supply and near-costless nature, no wonder several people are now making the shift from fossil fuels to solar power.
Types of solar energy
The basic idea behind solar thermal is that the sun heats water that gets circulated through the home or office. The water helps maintain the temperature of the space. A glycol solution or water is circulated through heat exchangers. The sun heats the liquid, and the exchanges help cycle the water through the home or office. Brick, stone, asphalt, and concrete also hold a great amount of heat and release it slowly over time. Solar how to websites cover a wide range of information including solar thermal.
Solar Electric Power
Electricity is produced using power from the sun by using photovoltaic (PV) cells. A chemical reaction caused when the sun hits the PV cells creates electricity. The PV cells are made of smaller cells. To produce a useful amount of electricity, cells are combined to create solar panels. The combined amount of electricity produced by each cell produces a specific amount of electricity. The resulting electricity can be stored in batteries or used as it's produced.
PV cells produce solar panels. Using a single solar panel produces about 12 volts of direct current and may help reduce utility costs in a small way. Solar panels may be wired together to create a solar array. The more solar panels used per project, the more power will be stored or used. The amount and intensity of sunlight, cloud cover and other weather conditions may affect the amount of power produced by solar panels.
Do solar panels work during sunless days?
One of the most commonly asked questions is "What happens during cloudy days/night?" Cloudy days can indeed decrease the amount of power your solar panels produce.
Hopefully, there'll be more breakthroughs in terms of storing energy during the day so they can be used during off times. But in the meantime, it's best to remain connected to your electric power provider. When your panels produce an excess of power, your utility bill will be reduced. When they do not produce enough power, you will still be covered by your local utility company.
Regardless, there are several monetary benefits to using solar power. Here's an informative graphic to further expound:
Solar-powered planet: Is it possible?
For billions of years, the sun has been a major provider of earth in many ways possible, as it enables life on the planet. That's why solar power and solar energy are not new concepts. Our planet has used solar energy since the beginning of time. Without solar energy, life on Earth would not exist. The absence of solar energy would mean no plants, heat, food or people. The creation of products and technologies to help mankind harness some of that power was inevitable.
Solar energy may even help reduce or reverse the decline of natural resources and the rise of climate change as caused by fossil fuels. While it is true that present manufacturing of solar components uses fossil fuels, the day is quickly coming when fossil fuels will be removed from the equation.
Is solar right for you?
Each person has to make that decision on their own. Do your research on solar power. How would it affect your quality of life? How would it impact your finances? Does your current location receive enough sunlight to allow proper function of solar panels? These questions and much more will help you make the decision. In the meantime, many utility companies are researching solar and finding ways to implement it on a much broader scale.
Keep in mind that the power you produce is free, as you simply convert the sun's openly readily accessible energy into electricity. By catching sunlight, the PV panels convert it to electrical energy--and all that with negligible operational and maintenance costs required! It's a highly cost-effective source of power.Read More
I think we can all agree that solar power, with all its renewable and sustainable advantages, should be harnessed and maximized...right?
And among ideas by which we can further optimize the harvest of solar power energy is via the creation of solar roadways, or intelligent roads that could harvest solar energy and generate electricity, among many things. In this article, we’re going to flesh out just how solar roadways can achieve such ambitious goals and why they could be the next big thing in the solar power industry.
Energy from solar roadways
Importance of renewable energy
Today, solar energy is fast becoming an important source of power as exhaustible sources of energy like petroleum, coal and other fossil fuels are losing their impact due to the threat of climate change. As we all know, several scientific studies have concurred that climate change, the world’s leading environmental issue, is primarily caused by human activities, particularly the burning of fossil fuels. Moreover, fossil fuels account for more than 80% of total US energy consumption for more than 100 years, according to a 2016 report.
However, the continued use of these fossil fuels has become expensive and highly unsustainable, as such sources of energy as nonrenewable. Therefore, it’s imperative to harness solar energy, a much safer and even affordable source of power, for everyday purposes.
What is a solar roadway?
If you haven’t heard of solar roadways yet, then it’s probably because you’ve heard it being called by another name: smart highway. It’s a collective term for proposals to incorporate technologies into roads for generating solar energy, for improving the operation of autonomous cars, as well as to optimize driving conditions. The world’s first photovoltaic road opened in Tourouvre, Orne, France, which began construction in November-December 2016.
Here is a video detailing the first solar roadway in the world:
In a nutshell, solar roadways consist of a series of structurally-engineered solar panels on which vehicles can be driven. Each panel is made up of three basic layers. The road surface layer contains the solar collector cells embedded within and protects the electronics beneath it, and is engineered to provide good traction for the vehicles. The electronics layer collects the energy from the sun and contains a microprocessor board with support circuitry for sensing loads on the surface, controlling a heating element, lighting, communications, etc. Meanwhile, the base plate layer protects the electronics layer and distributes power and data signals "down-line" to all homes and business connected to the Solar Roadway.
With a microprocessor located every 12 feet, any problem would be immediately detected since solar road panels communicate with each other. If one of them stopped communicating, it would mean something was amiss and had to be checked. But the adjoining panels could still communicate and send the information to a central control station. The energy collected would simply move through a different path.
Why solar roadways are greatly advantageous
With the energy from solar roadways, you should have a decentralized grid, which would greatly benefit the use of solar-powered vehicles as they could be recharged at any convenient stop. Cars could be plugged in and recharged while the drivers ate or shopped, and they would always have enough charge because charging posts would be available everywhere.
By replacing all current petroleum-based asphalt roads, parking lots, and driveways with solar road panels, a solar roadway would hugely benefit the environment and people's lives. Such a roadway would become the power grid itself, eliminating the need for utility poles and relay stations, since power would be generated everywhere. Plus, the excess energy collected by this roadway would be stored for use when sunlight is absent and thus replace the need for the current fossil fuels used for the generation of electricity. It would also cut greenhouse gases literally by half as it promotes the use of solar energy, thus reducing humankind's carbon footprint and mitigating the causes of climate change and global warming.
Being able to cut down on energy costs while helping save the planet is the ideal lifestyle, isn’t it?
With everything that’s going on about the environment, it wouldn’t help to do your part while also benefiting from it. That’s why switching to solar as the primary source of energy has become the hot new trend lately, thanks to its affordability and sustainability. But what else makes it the best energy solution? This article will discuss the many advantages of using solar power for your home or building.
Why solar is the best energy solution
Why shift from fossil fuels to solar power
Over the years, the use of fossil fuels, the chief source of energy for several countries, has become a great concern to the globe. Fossil fuels appear in three forms: natural gas, oil, and coal, which have provided more than 80 percent of total US energy consumption for more than 100 years, according to a 2016 report. However, the continued use of these fossil fuels has become expensive and highly unsustainable, as such sources of energy as nonrenewable. Moreover, there’s been an overwhelming consensus in the scientific community that human activities, particularly the burning of fossil fuels, are changing the earth’s natural greenhouse.
To replace fossil fuels, the world is looking for another great source to solve this problem. If the problem with fossil fuels was its sustainability, then alternative renewable energy sources like wind, hydroelectric and solar power provide unlimited availability. And since solar power is an infinite source of power, it makes for a more sustainable and affordable power source.
Solar energy remains one of the best alternatives to fossil fuels as it helps mitigate the rise of climate change. Many people now want their commercial properties and homes to use solar energy. Due to the constant availability of sun throughout the year, solar energy is the deal. It is the most reliable and consistent forms of power to depend on, time and again.
How solar power works
People can now use solar energy in two forms such as heat and electricity via photovoltaic cells. The advantage of using photovoltaic cells is that there is no release of harmful gases into the air. Photovoltaic cells do not need direct sunlight to generate energy. The most important thing for photovoltaic cells is the availability of daylight, regardless of whether it’s cloudy or not.
Do you know that electricity can also be generated without a direct energy source? This is possible by using solar energy to generate heat first. The steam from the production process can now work in power generators. At this juncture, it is unequivocal that fossil fuels will not produce heat. The resulting energy remains 100 percent eco-friendly.
Advantages of solar power
There are several benefits to using solar power, among which are:
Solar power is renewable
Converting solar energy into electricity remains a simple task. With the help of solar panels, the conversion process will become successful. The sun is always a consistent source of energy, which people use, time and again. With solar energy, importing coal from other nations will reduce. In remote areas, solar energy can help in the generation of electricity.
Using fossil fuels as energy sources are actually expensive. From mining for sources to transportation, it’s an incredibly arduous task. Solar energy, on the other hand, requires none of those things.
When fossil fuels are in its processing form, you will see the unleashing of harmful gases. Sulfur oxide, nitrogen oxide, and carbon dioxide all emanate from processing fossil fuels. Solar energy, on the other hand, remains the cleanest and purest form of power. Using solar energy to replace fossil fuels will help to protect the planet.
Easy to install
Installing solar panels is not a Herculean task. You can install these panels on your roof or other easily accessible places. For other forms of energy, such as geothermal and wind power, a huge area is crucial for installation. Such is also necessary for solar farms, but for households that individually pursue solar energy, panels are a great go-to.
Easy to maintain
To maintain solar panels, you do not need any strenuous task. While first investments in solar panels remain huge, there are no recurring costs for investing in solar panels after installation. With time, you have the opportunity to add extra solar panels.Read More
It would be great to do your part for Mother Earth by committing to a greener, more eco-sustainable lifestyle by using renewable sources of energy, wouldn’t it?
That’s why knowing the most advantageous sources of energy should be among the list of chief concerns for everybody. With fossil fuels proving to be among the chief catalysts for climate change, renewable energy is closely becoming an imperative. Among the options are solar and wind power, which this article would discuss and compare in order to know which one is more efficient.

Which is more efficient, solar or wind?
Renewable sources of energy
Climate change is quickly becoming a harsh reality for the planet. Several scientific research concurs that human activities, primarily the burning of fossil fuels, are the No. 1 cause of climate change. As a result, greenhouse gases like carbon dioxide have reached unprecedented levels by the turn of the millennia and will continue to do so unless people contribute to mitigating such damaging consequences.
With the continuing progress for harvesting solar and wind power, consumers are changing the way they look at powering their homes. Instead of using fossil fuels, which pollute the planet, many environmentally conscious people are turning to these clean and renewable energy sources to power their homes and businesses. The environmental benefits of the solar and wind energy are their greatest selling point, as they improve air quality for us all by minimizing emission of greenhouse gases like carbon dioxide.
Harvesting wind energy operates on an unbelievably simple principle. By converting kinetic energy into mechanical power, wind turbines can produce clean electricity. Here is a good photo of how it works.
There are several things that you should keep in mind if you intend to invest in wind power, however. Right off the bat, your property must have a decent wind asset and you should check with your neighborhood government to ensure that tall towers are permitted in your general vicinity. But should you choose to go this option, then you should know that wind power can bring down your power charge by half to 90 percent, and enable you to avoid high expenses of having utility electrical cables stretched out to remote areas, forestall control interferences and contamination.
Like wind power, solar power is relatively easy to understand—it’s merely the process of using solar energy to create power using photovoltaic tiles. Solar power systems (also called solar energy systems) work with solar panels to acquire the beams of the sun. Technically, they catch the beams of the sun, and in doing so release electrons. Those electrons are then obtained and used as electricity. More electrons to obtain, the more power you generate.
Solar power is a decent power source especially for households in an urban zone. Unlike wind power, however, individual households can utilize solar power by installing solar panels in their homes and do not need a large patch of land for such energy harvesting. Solar farms, however, are altogether different.
There’s been a surge in favor of solar power industries lately as several homeowners and companies are making the shift to this renewable energy source. In fact, thanks to the United States and China, solar power use has jumped by 50 percent worldwide. Europe, however, remains the leading solar power user globally. This is because of the many benefits of solar power use, including cost efficiency and effectivity.
Which is more efficient: solar or wind power
When choosing between wind and solar energy, you ought to decide how much power you need or need to deliver, and what works for you financially. In general, however, solar power proves to be the best solution in terms of accessibility, ease of maintenance and upkeep, and costs.
To take advantage of green energy, you do need to be a homeowner. If you are renting an apartment or renting a home, it doesn't make sense for you to bring in a solar energy system. If you are even allowed to bring one in, you will not come close recouping expenses associated with that system.
For homeowners, the results can be amazing. First, when you set up green energy (whether wind or solar), it will increase the value of your home greatly. Because many houses are not yet equipped with green energy, those that do are in high demand.
Can you completely disconnect from an electric power generator?
Many people will still be connected to the utility company for electricity. Solar energy will not work at night just as wind energy cannot be generated when there is no wind. That’s why you still need to have an account with an electricity generator company.
This actually works to your advantage: utilities will definitely buy electricity back from you when you produce more than you can utilize. For example, if you are out of your home for the day and shut off all of your electronics, lights and other equipment, your electricity usage in the house will be extremely low (you will, of course, leave your refrigerator connected). While you are out, the house's solar and/or wind systems keep producing electricity. If you are not there to use it, it will be pumped back into the power grid and actually be utilized by your neighbors!
As you do this, the electricity company pays you for the electricity you pumped into the power grid generally at the same rate as they would charge you! It's a great phenomenon to watch when you step outside your house, look at your power meter, and watch it turn backward!
Getting started with solar and wind is a simple process. However, you will need to do your homework and speak with an expert. Make sure you get all the facts before you start and, as with any other major purchase, make sure you are dealing with someone reputable.Read More
With global warming emerging as the planet’s No. 1 environmental problem, renewable sources of energy are becoming the way to go...right?
That’s why, in recognition of this increasing demand for a more sustainable energy generation, solar power is slowly becoming a global trend. Thanks to the renewable and ubiquitous nature of sunlight, it’s no wonder that solar power is one of the most efficient and affordable sources of energy. This article will discuss the benefits of making the switch to solar power and why you should consider this as your primary source of energy.

Benefits of solar power
Why solar power
Several scientific studies have concurred that climate change, the world’s leading environmental issue, is primarily caused by human activities, particularly the burning of fossil fuels. Over the years, the use of fossil fuels has provided more than 80% of total US energy consumption more than 100 years, according to a 2016 report. However, the continued use of these fossil fuels has become expensive and highly unsustainable, as such sources of energy as nonrenewable.
As it stands, the energy sources we have now is not only nonrenewable, but their byproducts have a detrimental affect on us and the environment. That's why solar power has become a top choice among renewable energy sources, thanks to its several benefits, like low upkeep and maintenance costs, as well as cost efficiency. Here's a good guide to solar power for homeowners, if you are interested:
Solar power is eco-friendly and renewable
This is where solar power comes in. As we deal with huge environmental crises such as global warming, there's never ever been a more important time to switch to solar power. It’s eco-friendly, unlike standard electrical power and fuel, as it does not cause pollution at all.
Solar power is probably the best renewable resource that we have available today. The technology is there, the systems are there, and it just makes perfect sense to use power from the sun to power our lives. Do not think that solar power is much more expensive than other alternatives because solar power is probably the least expensive option out there. As long as you have a roof over your head, you can use that space to make power and to save money.
In fact, you can even sell power back to the electric company simply by having a quality solar unit installed on your roof. According to the energy department, any excess electricity you produce can be redistributed to your power grid, allowing you to cut down on costs as well as earn tax incentives.
Cost-effective and low-maintenance
Solar power is also cost-effective. Thanks to its trending usage growth, solar panel prices have dropped by more than 60 percent over the last seven years. There also exists little to no upkeep needed for solar energy systems. All you have to do is set them up and they do the job.
Another benefit to using solar power as you can continually add to what you already have. Many people choose to install one or two panels at a time, and the more panels you install, the more money you will save. So, even if you just want to start with one panel now, you can always build up later and enjoy becoming energy-independent and even generate power for your electric company.
Given all these, now is the best time to get involved with solar power. See what it can do for you, and you will be delighted with how much money you save every month. There are several incentives in place to encourage people to make the transition. So if you are interested in learning how you can make the switch, visit a great and informative website that has all the information you need.Read More
Wouldn’t you agree that having a constant source of power for your cell phones is a great advantage?
Being the most widely used device by several people across the globe, cell phone use accounts for a large part of our electricity as we constantly have to recharge their depleted batteries. Thankfully, cell phone chargers are devising ways to go green in order to do their part in environmental-friendly ways. This article will discuss just how cell phone companies could achieve that.
Cell phone chargers to go green
As of 2015, roughly nine out of ten adult Americans own smartphones, while tablet users have jumped to 45 percent. With its increasing ubiquitousness, however, means that charging them makes for a large part of our electric consumption. No worries; reports have concluded that cell phone charging costs less than a dollar a year. But the real threat to our ecosystem, really, are the pollutants that compose a charger—lead, cadmium, mercury—which create toxic wastes in landfills.
Thankfully, handset manufacturers have recognized the importance of manufacturing not only an environmentally-friendly handset but also eco-friendly chargers.
Renewable energy as sources of cell phone power
A need for the mobile communication to go green has brought forward innovative designs to harness renewable energy for cell phone chargers. Solar energy, wind energy, and kinetic energy are just some of the few prospective energy sources for chargers.
Major players in the mobile industry are getting their hands deep into manufacturing solar-powered cell phones. Blue-earth by Samsung, Pop by LG and two other Sharp Models are among the new solar-powered cell phone prototypes.
Ecofriendly cell phone chargers
With eco-friendly cell phones gaining popularity, cell phone chargers, too, are going green. Many chargers are composed of environmentally friendly materials and then powered by renewable energy sources, like wind and solar power.
For example, India, which currently has the largest market for smartphones, has proposed the plans for cell phone towers that are powered by solar energy. China Mobile, a top Chinese telecommunications operator, has already set up the world’s biggest solar-energy-powered mobile communication.
Nokia, meanwhile, is trying to manufacture cell phones that use ambient radio waves. The prototype is believed to harness 50mW of the power from radio waves, which is enough to power a cell phone on standby mode.
Other future ideas
Using kinetic energy in generating power for cell phones are also being explored. This is the principle behind wind energy generation. Other unconventional sources for power currently being tested are alcohol or cold drinks. They may seem unlikely, but they are no more outrageous than being able to build solar-powered roads--and that has been accomplished!Read More
I think we can all agree that solar power is one of the most sustainable and affordable energy sources right now...am I right?
Even more fascinating is that, apart from being generally cheap, solar panels have even cheaper options that could help you cut costs. One such example is carbon-based solar cells, which is proving to be a more efficient and cost-effective option over its contemporary, silicon photovoltaic cells. This article will discuss how carbon-based cells work and how they compare versus silicon cells.
Carbon-based solar panel cells
Right now, solar power is feted as the best renewable energy solution available right now, thanks to its several benefits, including cost efficiency and effectivity. It comes as no surprise, therefore, that there have been several efforts to progress in this industry by producing solar-efficient devices, from cell phone chargers to roads.
Ironically, one of the things that the industry hasn't cracked yet is the creation of a more light-absorbent solar panel. This is where carbon-based solar cells would come in.
Where solar panels are right now
Right now, the most commonly used type of solar panels is silicon-based solar cells, which are manufactured in China and Taiwan. Interestingly, however, silicon is only used because it’s easier to use, not necessarily because it’s the best option for optimal light absorption. And because pure silicon is expensive and can pose a disposal challenge, it’s the primary reason why solar power remains to be an attractive option for energy generation on a large scale.
Sometimes, scientists could use other substances like ruthenium, which is cheaper but rarer. As such, scientists have begun to explore carbon-based cells, as carbon is an abundant element and can be used for mass production.
How graphene-based solar cells work
Several studies have found that carbon is indeed an excellent option for photovoltaic cells and can be used for the next generation of solar panels. Scientists have found that graphene, a type of carbon structure in which the atoms lie in thin sheets of hexagons, has intrinsic properties that allow it to absorb light better.
A study from Stanford University, for example, also found that carbon sources can be found in renewable sources. This means there’s no need to mine the earth for carbon, and that carbon-based solar cells are much easier to dispose of or recycle.
Areas for further study
However, this discovery is not without hitch. While graphene-based solar cells absorb a wide range of light frequencies, scientists need to use large sheets of graphene, thus making it unmanageable to work with. These large sheets are very sticky and also get attached to the other sheets. As such, chemists and engineers are trying to work out a solution for a stickiness of the graphene. For now, the best way has been to break down the graphite top-down into sheets and then wrap polymers all over them.
Another issue is efficiency, as Stanford found that graphene-based solar cells’ conversion efficiency peak at 0.46 percent, while organic solar cells fall just below 10 percent efficiency. Some of the most advanced crystal silicon cells can top 25 percent.
This means there’s still long ways to go to maximize their conversion efficiency. Regardless, there is hope, as chemist Liang-shi Li from Indiana University says: ”Our own interest [in solar power] stems from the need to find … readily available material which can proficiently absorb sunlight. At the moment, the most well-known materials used in absorbing the light in solar cells are silicon and compounds that contain ruthenium.”Read More
With all the natural calamities that happen on a global scale, shouldn’t we do something to help mitigate global warming and its catastrophic consequences?
As climate change rears its ugly head, finding alternative sources of energy has become a top priority both among scientists and concerned citizens. And among the many renewable sources available, it seems like solar energy is the most efficient and effective way to help reduce global warming, as we will discuss below.

How does solar energy help reduce global warming
As you may have heard, the solar power industry in the United States is booming, perhaps because of the increasing recognition of its benefits toward a more sustainable environmental lifestyle. Researchers have found that nearly 260,000 Americans work in solar—or more than double the number in 2012—in more than 9,000 companies in every US state. This increase has also led to a rise in solar power’s share in electricity generation to more than a third. Meanwhile, the cost of installing solar systems have dropped drastically since 2010.
There’s no doubt that solar energy is fast becoming the trend when it comes to energy sources and electricity generation. But why is that so?
What is solar energy?
Solar energy is energy that is generated from direct sunlight. It is one of the most permanent and environment-friendly sources of fulfilling power demands available throughout the globe. The best thing about this type of energy is that they do not harm the environment in any form and is capable of meeting increasing energy demands across the globe.
There are various advantages of using these environmentally friendly sources of power and energy. But the most important benefit of using solar power is it does not release pollutants and is thus very eco-friendly. And because solar power is virtually unlimited, it’s readily available.
Difference between solar and wind energy
As of now, both solar and wind energy are considered to be the top most viable renewable sources of energy. Wind energy is another viable option to solar power as both are nonpolluting and renewable. But it does have its drawbacks. For example, the large windmills could contribute to noise pollution, a great disadvantage especially since wind farms are located in quiet, out-of-the-way communities with vast space. Moreover, it cannot generate power if there is no wind.
How solar power can affect global warming
If you are concerned about global warming and its harmful consequences to the planet, then solar energy is for you. Solar energy is clean, renewable and sustainable, and it can help protect our environment as it does not pollute our air, unlike traditional forms of electrical generators does. It actively contributes to the decrease of harmful greenhouse gas emissions.
Solar energy system is virtually maintenance-free, and because of this, it could last decades. There are no recurring costs needed after you install the system. It works silently, does not gives out any smell, and it certainly does not require you to add any fuel. You can even add more solar panels easily in the future when your family grows.
Here is an infographic expounding on the financial benefits of using solar power:
Disadvantages of solar systems
One point that you have to take note is that solar panels require quite a large area for installation to achieve a good level of efficiency. This would rely on the location of the solar panels. Not to mention that the production of solar energy is also influenced by the presence of clouds or pollution in the air as well. Nevertheless, this problem can be overcome with the installation of certain components.
Moreover, solar power cannot be generated during the night. Thankfully, solar panels include battery reinforcement frameworks as well as net metering. Introducing net metering during the evening will enable you to spare power and cash as well.
Now that you are armed with this information, you will be able to make a clear decision whether or not solar energy is right for you. If it does, what's stopping you from carrying it out? Go to your nearest electrical shop and install one today. Remember, you will not only save money, but you will also help save the environment.
Just remember that if many people start making effective use of solar energy, then it can reduce the use of fossil fuels like coal to produce power. That way, we can mitigate the consequences brought about by greenhouse gases.
Energy from the sun essentially free. Moreover, the US government actually has several tax incentives in place for households and companies that use renewable energy. Considering its many benefits, solar energy ought to be a primary consideration for every household.Read More

Why it's smart to invest in solar energy
What do solar energy systems do?
Solar power is pretty self-explanatory. Solar energy panels are fueled by solar energy, which requires only the sun rays to function. Since solar power is the most abundant form of energy available on earth, the potential of solar energy is almost infinite. According to the National Energy Laboratory, the average system can reduce costs about 50 percent of your utility costs. Furthermore, if your system generates more electricity than you need, you can throw back the power to your local power grid and generate profit in return.
How is solar power sustainable?
Solar energy systems consume no fossil fuels and generate zero emissions, making them a renewable energy source. Emissions produced from fossil-fuel based power plants release nitrogen oxide, sulfur dioxide, carbon dioxide and some amount of mercury. Meanwhile, a solar system's ability to operate without oil, coal, and fuels ensures that the power will be created in a natural way.
As time passes, the demand for solar panel technology increases because the prices of nonrenewable resources are rising. It is the right time to look for inexpensive and alternative means of energy for uninterrupted power to meet your energy needs.
Benefits of installing a solar power system
For those interested in installing a solar power system, it’s not that difficult: apart from its relative ease of installation, the expenses are comparatively low. Solar panel system prices have been going down by as much as 70 percent.
In an effort to help boost the number of people using solar panel technology, both state and federal tax rebates and incentives are available to help shrink the cost of installing solar energy panels. These favorable rebates and incentives offered by the government can make switching to solar power more efficiently. The initial cost involved with setting up a solar system could be considerably high, but several states offer tax benefits for both commercial and residential solar panels.
