V3Solar

CoolSpin

V3Solar’s patented spin technology is a new paradigm that covers any spinning PV form factor. The second iteration of this revolution is the V3 CoolSpin, which competes directly with existing one sun mono PV solar panels with lower cost of components (34% lower) while providing far more effective and simpler energy production.

The CoolSpin product has been designed to be “plug compatible” with existing one sun solar cells. The CoolSpin can be made to fit existing bracketing and tracking products in the solar industry.

CoolSpin will be available for licensing from the second quarter 2013, with mass production planned the third quarter.

Main CoolSpin Benefits:

  • lower cost per watt (34.3% less than 1x sun solar panels)
  • only requires a single axis tracker with linear Fresnel (cost savings)
  • high tolerance to off axis tracking alignment
  • dramatic reduction in amount of PV required per watt
  • lower operating temperatures could lead to higher net efficiency

Through the patented CoolSpin technology energy is constantly provided from one sun mono PV that remains cool from the spin. The heat generated by the concentrated lens does not have enough time to transfer to the PV as it cycles out of the sunlight into the shade allowing the next piece of standard PV to go through exactly the same process, again, and again, and again. Constant cooling through dynamic spin creates higher power.

 

Solar Roadways

Introduction

SR

U.S. Senator Mike Crapo (R-ID) talks about Solar Roadways

Years ago, when the phrase “Global Warming” began gaining popularity, we started batting around the idea of replacing asphalt and concrete surfaces with solar panels that could be driven upon. We thought of the “black box” on airplanes: We didn’t know what material that black box was made of, but it seemed to be able to protect sensitive electronics from the worst of airline crashes.

Suppose we made a section of road out of this material and housed solar cells to collect energy, which could pay for the cost of the panel, thereby creating a road that would pay for itself over time. What if we added LEDs to “paint” the road lines from beneath, lighting up the road for safer night time driving? What if we added a heating element in the surface (like the defrosting wire in the rear window of our cars) to prevent snow/ice accumulation in northern climates? The ideas and possibilities just continued to roll in and the Solar Roadway project was born.

Our latest video – by Michele Ohayon

In 2009, we received a contract from the Federal Highway Administration to build the first ever Solar Road Panel prototype. During the course of its construction, we learned many lessons and discovered new and better ways to approach this project. These methods and discoveries are discussed throughout this website. Please enjoy and send us any questions that you may have.

After successful completion of the Phase I SBIR contract, we were awarded a follow-up 2-year Phase II $750,000 SBIR contract by the Federal Highway Administration beginning in 2011. With this award, a prototype parking lot will be built and then tested under all weather and sunlight conditions.

The heart of the Solar Roadway™ is the

Solar Road Panel™

The Solar Roadway is a series of structurally-engineered solar panels that are driven upon. The idea is to replace all current petroleum-based asphalt roads, parking lots, and driveways with Solar Road Panels that collect energy to be used by our homes and businesses. Our ultimate goal is to be able to store excess energy in or alongside the Solar Roadways. This renewable energy replaces the need for the current fossil fuels used for the generation of electricity. This, in turn, cuts greenhouse gases literally in half.

Solar Road Panel

Solar Road Panel

Each individual panel consists of three basic layers:

Road Surface Layer – translucent and high-strength, it is rough enough to provide great traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. It is capable of handling today’s heaviest loads under the worst of conditions. Weatherproof, it protects the electronics layer beneath it.

Electronics Layer Contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element. No more snow/ice removal and no more school/business closings due to inclement weather. The on-board microprocessor controls lighting, communications, monitoring, etc. With a communications device every 12 feet, the Solar Roadway is an intelligent highway system.

Base Plate LayerLayer – While the electronics layer collects energy from the sun, it is the base plate layer that distributes power (collected from the electronics layer) and data signals (phone, TV, internet, etc.) “downline” to all homes and businesses connected to the Solar Roadway. Weatherproof, it protects the electronics layer above it.

Scott presented the Solar Roadways at a TEDx Talk in Sacramento on April 16th, 2010. He was given 18 minutes for “The talk of his life” and it went great!

 

Overview

When multiple Solar Road Panels are interconnected, the intelligent Solar Roadway is formed. These panels replace current driveways, parking lots, and all road systems, be they interstate highways, state routes, downtown streets, residential streets, or even plain dirt or gravel country roads. Panels can also be used in amusement parks, raceways, bike paths, parking garage rooftops, remote military locations, etc. Any home or business connected to the Solar Roadway (via a Solar Road Panel driveway or parking lot) receives the power and data signals that the Solar Roadway provides. The Solar Roadway becomes an intelligent, self-healing, decentralized (secure) power grid.

Imagine a world-wide system where the “lit” half of the world is always powering the “dark” half of the world!

Everyone has power. No more power shortages, no more roaming power outages, no more need to burn coal (50% of greenhouse gases). Less need for fossil fuels and less dependency upon foreign oil. Much less pollution. How about this for a long term advantage: an electric road allows all-electric vehicles to recharge anywhere: rest stops, parking lots, etc. They would then have the same range as a gasoline-powered vehicle. Internal combustion engines would become obsolete. Our dependency on oil would come to an abrupt end.

It’s time to upgrade our infrastructure – roads and power grid – to the 21st century.

Advantages of Solar Power

Solar power systems have many benefits. They are quiet. They don’t produce any pollution. They are reliable, there are no moving parts to worry about, so they require minimal maintenance. Another great advantage of a solar power system is that it’s modular. The cells (or building blocks) are available in a wide variety of wattage, ranging from a mere fraction of a watt to more than 300 watts. Large solar power plants have higher megawatts, but most individual systems are much smaller. You can choose the solar power modules required to deliver the power you desire for your system.

One downside of solar energy is that much of the sun’s energy is lost during the process of transferring sunlight to electricity. To solve this challenge, larger and more efficient panels continue to be manufactured all the time. And while they are still less efficient than they ultimately might be, they are still the renewable energy system of choice because they require so little maintenance and are quite durable.

A solar panel system should last around fifty years, as long as it was properly installed. A pretty wise investment, all things considered! If you choose to install your own solar power system, you will appreciate its quiet, low-maintenance, pollution-free, safe and reliable operation, as well as the degree of independence it provides.

Renewable Energy Off the Grid

Renewable Energy Off the Grid

This page contains information on why and how to generate renewable energy while living off the grid, also you will find useful tips on how to satisfy most of your power needs without having to rely on the city for electricity. Generating your own power off the grid is very essential if you want to declare your independence and be fully or mostly self suffecient. Spending around $700 on wind generators and solar panels can reduce your power costs more than $1300 a year (especially if you build them and install them yourself), plus you will feel good about using green and renewable energy.

Benefits of Generating Renewable Energy

You can cut your electricity costs by 80%, or even make your power company pay you, and of course, you will feel good to know that you’re doing your part to save the planet from pollution. These are uncertain times, energy costs continue to soar, natural resources are being depleted at an alarming rate, and pollution and global warming continue to worsen. While it can all seem distant and overwhelming, the solution to each of these issues actually lies within each of us. Our actions today can create change. Our daily decisions do have an impact on the world at large.

Harnessing the power of wind and sun is not only possible by most people, but it’s increasingly affordable and easy to set up. But before discussing ways to harness wind and solar energy, it’s very important to note that, the first step to start, is by changing our behaviour. Right now, even though renewable energy is not exactly cheap and often not very accessible in its current state, there are still plenty of ways you can cut down on energy costs. Here are just a few:

•  Turn off your appliances when you’re not using them. Computers and televisions continue to use energy even when they’re in standby mode.

•  Instead of always using your dryer or dishwasher, consider air-drying your clothes and dishes at least some of the time, and only run your dishwasher, dryer, or washing machine with full loads.

•  Use energy-efficient fluorescent lightbulbs in your household lamps.

•  Set your thermostat at a comfortable but moderate temperature – not too warm in the winter, not too cool in the summer.

•  Take shorter showers and avoid baths.

•  Maintain your vehicle – regular tune-ups insure that you get maximum fuel efficiency. When you drive, be aware that excessive speeds and rapidly accelerating and braking uses more gas.

•  Seal your windows and doors. Preventing warm or cool air from escaping will make a significant difference in your utility costs.

If you are seriously considering using renewable energy sources like wind or solar power to heat and cool your home, then you MUST implement the suggestions above. There’s simply no value in using a wind or solar generator if you continue to leave lights and appliances on when not in use, use more water than is necessary, etc.

Stanford Scientists Develop Peel-and-Stick Solar Cells

Stanford Scientists Develop Peel-and-Stick Solar Cells

SOLAR TECHNOLOGY NEWS | JANUARY 11, 2013 BY  | 0 COMMENTS

Stanford University scientists have developed a flexible, decal-like thin-film solar cell that can be attached to almost any kind of surface.

These solar cells can be produced using conventional, industry-standard materials and methods.

According to the team of scientists, the peel-and-stick method provides a simple way of integrating thin film solar cells into buildings, clothes and many other unconventional substrates.

Step-by-Step Guide to Saving on Solar

The cells are made by depositing a 0.3-micron layer of nickel on a standard silicon wafer, which then has a standard, hydrogenated amorphous silicon thin-film solar cell deposited on top of that. A protective polymer covers the wafer, and then a thermal release tape is attached to the top of the solar cell that can be peeled off and stuck to almost any surface.

According to lab testing, the peel-and-stick process leaves the thin film cell completely intact and retains its performance through thousands of bending cycles.

“The silicon wafer is typically undamaged and clean after removal of the solar cells can be reused,” said Xiaolin Zheng, lead researcher of the Stanford team.

“Now you can put them on helmets, cell phones, convex windows, portable electronic devices, curved roofs, clothing—virtually anything,” he added.

According to the researchers, this new process has enabled the further reduction of the cost and weight for thin film production and has enhanced flexibility and attachability for broader application areas.

5 Reasons a Radical Shift to Solar Power Makes Perfect Sense

5 Reasons a Radical Shift to Solar Power Makes Perfect Sense

August 1, 2012 By  Leave a Comment

solar panels

The vast potential of solar power is extraordinary.

For many years the idea of switching from reliance on power plants for electricity torenewable energy sources such as solar power was considered by most in the U.S. to be a far-fetched and unreasonably costly proposition.  Whether mostly due to the cost of solar panels or political pressures related to keeping the need for fossil-fuel a national priority, the switch to renewable energy moved at a snail’s pace for decades.  In the meantime, more and more homeowners have recognized that switching to solar power makes good sense, especially since the related costs are significantly less, it now seems more far-fetched to continue relying on fossil-fuel run power plants for electricity.

Individuals across the U.S.A. are making the decision to go solar and to take on other initiatives which contribute to genuine energy independence and a cleaner world.  True energy independence with solar power:

1. Is self-generated.  When an electrical power grid goes down, blackouts occur, which can be catastrophic.  Think of notorious New York City blackouts; the entire metropolis comes to a grinding halt.  There are many potential dangers linked to a blackout, not to mention the incredible inconvenience of the situation.  On the other hand, any homeowners or companies who rely on solar thermal energy for their hot water needs are almost immune to short-term electrical blackouts.  In addition, the more solar PV systems there are, the smaller the chance that a power plant will shut down due to overwhelming demand.

2. Is renewable.  There is a limit to the amount of gas, oil, and coal that is practically, economically and safely accessible within the earth.  Some researchers have projected that at the current level of demand, the earth will run out of these resources by the next century.  On the other hand, sun, wind, and geothermal energy are limitless resources. Did you know that more solar energy strikes the earth in one hour than the world’s population uses collectively in a year?

solar power results

Create a cleaner future for generations to come.

3. Doesn’t compromise the health of industry workers.  Anytime someone chooses to work in a coal mine, they know that they may be making a choice that sacrifices their health in exchange for a job.  Employees in the renewable energy industry, however, don’t have to make such a sacrifice.  Of course, there are places in the U.S.A. where coal mines are the backbone of the economy and are important to the citizens, in spite of the inherent dangers.  But the radical shift to renewable energy doesn’t have to mean widespread job loss.  Workers can be trained in other fields, including clean energy, and hold on to their health at the same time. In less than a century much of the industrialized world has gone from horses to cars. We can and must make a similar transition with energy.

4. Can eliminate dependence on foreign sources. Due to speculation, political manipulation and worldwide economic influences; even if the current hindrances to drilling in the U.S.A. were removed, our country would still need to import foreign oil, to keep up with demand.  The components for solar PV systems can be produced domestically thus generating jobs; and, of course, renewable energy sources are supplied by nature in real time.

5. Minimally affects the environment.  All components of solar panels are made with materials which can be recycled.  Little to no damage to air, land, or water is caused by using renewable energy sources. Furthermore, as even more refined manufacturing processes evolve any trace residues and polluting byproducts related to the PV manufacturing process are progressively being reduced or eliminated.

Imagine what a better world future generations will be able to enjoy when this radical shift to using renewable energy supplies such as solar panels becomes the norm.   For a happier and healthier future, for generations to come, visit the North American Solar Store near you.

 

Watch Legendary Bruce Oreck’s Plenary Presentation from WREF 2012

Long but good

Bruce Oreck, the U.S. Ambassador to Finland, began on one of the days at WREF with a talk on how to use language effectively to promote renewable energy. Oreck’s presentation focused on using a different style of language than currently used to promote renewables. For example, instead of using the phrase that renewable energy “saves money,” focus on using “making money” by going solar instead. You can view Oreck’s presentation from WREF here:

Solar Windows

If you picture the glittering glass skyscrapers that dot America’s cities, it becomes clear why the idea of using that vast window space to generate solar power is gaining traction. In 2009 alone, 437 million square feet of windows were installed in non-residential buildings in the United States. That many square feet of standard solar panels would generate around 4 gigawatts of power, roughly the total installed solar capacity in the U.S. today.

Such potential is leading engineers and entrepreneurs to more intensively explore the idea of turning windows into solar-power producers. Solar windows, a subset of the growing field known as building-integrated photovoltaics, are based on the concept that a window doesn’t need to be 100 percent transparent, and a solar panel doesn’t need to be 100 percent opaque. Several ways currently exist to turn a window into a power-generating device, from thin-film silicon, to dye-sensitized solar cells, to tiny organic cells.

New Energy SolarWindow

Some experts think the field is poised to take off, and although the world may not see an all-solar skyscraper for a while, a number of companies are promising commercial-scale production of various solar windows in the next two years. Still, the cost and technical hurdles facing this fledgling technology could get in the way of a future filled with towering, emission-free power plants. Like other cutting edge alternative energy sources, energy-generating windows could become a mainstay of a greener future in the coming decades, or they could prove to be impractical and produce only a fraction of solar-powered electricity.

“The challenge is whether you can get the cost down and the electricity generation up,” says Sarah Kurtz, a scientist with the U.S. government’s National Renewable Energy Laboratory (NREL) in Colorado. “There are lots of different schemes and strategies, and creativity will be the name of the game. If you can get the cost to the place where those windows don’t really cost any more than conventional windows, it obviously makes sense to go ahead and have your windows generate electricity.”

Building-integrated photovoltaics, or BIPV, is moving slowly, with solar panels now doubling as walls, shingles, and other parts of buildings. MJ Shiao, a senior analyst at GTM Research, a market analysis group in Cambridge, Massachusetts, says the market still represents only around 1 percent (a few hundred megawatts last year) of solar powerbeing installed around the world, and that’s mostly rooftops or semi-opaque skylights. Windows pose a greater challenge than rooftops or walls because of the need to actually see through them. So far, very few examples of skyscrapers with solar windows exist; the highest profile site is the Willis Tower (formerly Sears Tower) in Chicago, where Pythagoras Solar installed a small prototype in 2011.

Several technologies have emerged for solar windows, though none have yet taken off in a meaningful way. But one company that says it is close to commercial deployment is New Energy Technologies, based in Columbia, Maryland. It has developed a method for spraying tiny organic solar cells onto windows in a see-through coating that lets in 40 to 80 percent of sunlight, absorbing the rest. With 10 patent filings pending and no commercial prototypes yet in the field, the company is divulging few details. But the spray-on method could reduce production costs dramatically. Recently, the company announced the development of a large solar cell — 170 square centimeters — made in collaboration with NREL, which could make adding the cells to windows even cheaper.
Despite the company’s progress, its technologies highlight one of the major obstacles to solar windows: efficiency. The rate at which a solar panel turns the sun’s energy into electricity is a concern for all types of solar power, but especially for windows. “The challenge is that the light you see, if you absorb that and use it to make electricity, that means you don’t have a window anymore,” says Kurtz.

To date, the record efficiency for an organic solar cell is 10 percent, and production line efficiencies never get up to the record levels. While traditional solar panels are now producing power with 15 to 20 percent efficiency, efficiency levels for solar windows of roughly 5 percent are unlikely to be economical.

“Look at it from a physicist’s point of view,” Kurtz says. “A solar panel that’s put out in the desert in a nice location with lots of sunshine may have something on the order of a one-year payback. If that [panel] sits out there for another 20 years, you get that much return on your investment for society.” If a solar window can only achieve one-third the efficiency of a solar panel, then it will take three times as long to pay back the investment.

But some experts think it’s just a matter of time before efficiencies rise high enough — and costs drop low enough — to make solar windows a sound investment. Andreas Athienitis, a professor of mechanical engineering at Concordia University in Montreal who is working on technologies for solar windows, says more mature technologies like thin-film silicon might represent a short- and mid-term solution for BIPV, until organic cells can catch up and meet long-term goals. “I think eventually it will be a big market,” he says, but the adoption is slow because “it’s a disruptive technology.”

organic-valley-solar-windows

Another company using organic solar cells, Heliatek, based in Germany, has panels that can achieve 8 percent efficiency. The company’s organic cells use molecules called oligomers rather than traditionally used polymers — basically, short rather than long collections of atoms — which means cheaper, more precise application of the cells. Heliatek says it expects that within five years it can manufacture solar cell windows in the 50 cents-per-watt range, making them competitive with other solar technology.

Spain-based Onyx Solar offers a number of solar glass technologies. However, its windows only allow up to 30 percent of sunlight through, so a lot of light inside the building is lost. In varying formations, though, Onyx says its amorphous-silicon solar glass — a type of thin-film silicon cell — can get up to 9-percent efficiency.

But such efficiencies don’t take into account some of the practical limitations of actually covering a skyscraper with solar windows.

“The optimal installation for solar is you want it to be facing south, you want a slight tilt to it, and you want good solar access, so you don’t want anything to shade those panels,” says Shiao, of GTM Research. “The problem with skyscrapers is suddenly you’re putting them in vertical orientation, there’s only one south side to the building, and chances are that skyscraper is next to another skyscraper, which is going to shade that side of the building.”

Such challenges have left Shiao and other experts skeptical that solar windows will have a bright future. “There are a lot of technical and design challenges, which quite honestly aren’t going to be fixed,” Shiao says. “It doesn’t make sense almost at any cost, unless you’re getting the panels for free or something, to really install that system on those big structures.”

These obstacles haven’t deterred numerous fledgling companies. Oxford Photovoltaics, spun out of research done at Oxford University, says that computer modeling of a 700-foot skyscraper in Texas suggests thatcovering it in solar windows would generate up to 5.3 megawatt-hours per day of electricity. That’s enough to power 165 homes, and it could provide a skyscraper with sufficient power for all its lighting.

Oxford’s technology involves a type of cell for solar windows called a dye-sensitized solar cell. Dye-sensitized cells use a photo-electrochemical process to generate power and can be made relatively cheaply. Oxford’s transparent panels are so far getting around 6 percent efficiency, and the company hopes to bring them to market late next year.

Nazir Kherani, a professor of engineering at the University of Toronto, believes that the economics of solar windows may be most compelling for new construction with a focus on net-zero energy buildings — not for retrofitting existing skyscrapers. “With sufficient attention to design and seamless engineering, it is conceivable that we may see such buildings gradually evolving into net-zero communities, villages, and towns,” Kherani says.

Several companies involved in solar window production say they are within a year or two of scaling up or bringing a product to market, and they maintain that cell efficiencies will continue to rise and prices continue to fall, as is the case with solar panels.

What continues to drive the inventors and entrepreneurs involved in developing solar windows is the enormous potential for energy savings. Buildings accounted for 41 percent of all electricity consumption in the U.S. in 2010, more than transportation or industry. Taking a bite out of that with power-generating windows is an alluring target.

“I wouldn’t write off the possibility,” Kurtz says. “How soon will it happen? I find it’s really dangerous to predict the future.”

The Sun Rises on Solar Power



The Sun Rises on Solar Power -- Ford Focus Electric -- © Westend61/SuperStock
by Denise DiFulco
The price of solar electric systems has fallen rapidly in recent years, making solar energy more accessible than ever. In 2010, the installed cost of residential and commercial solar photovoltaic power systems fell by 17 percent from the previous year, falling an additional 11 percent in the first half of 2011, according to a report by the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab). So is now the time to take the plunge?
Well, such statistics don’t mean that solar power systems are cheap. The average cost nationwide last year was $6.20 per watt, says Ryan Wiser, a Berkeley Lab scientist. An average-size home (about 2,000 square feet) generally requires a 5-kilowatt system — approximately a $31,000 investment. “There’s a large up-front cost, but there’s also economies of scale,” Wiser says. “The cost per unit on a smaller system will be higher.” So if you opt for more power — say, a 10-kilowatt system — the price per watt will be substantially lower. Your circumstances could also help: It’s cheaper to install a system on new construction versus an existing home. There are several ways to defray the overall costs. One is through state and federal solar energy rebates. A list of current rebates is available through theDatabase of State Incentives for Renewables and Efficiency. Another is by entering a net metering agreement with your utility company. When your system generates more power than you need, the excess returns to the electricity grid and your meter runs backward. This allows you to receive full retail credit for the power your system generates. A way to avoid up-front costs altogether is to lease. Leasing has become a popular option in recent years, Wiser says, with more than half of new installed systems being leased through companies such as SolarCity, SunRun and Sungevity. How much you can potentially save on electricity depends upon many factors, including the size of the system you choose and your current retail electricity rate. Online calculators, such as Berkeley Lab’s Home Energy Saver, can help you make that determination. They also can help assess other ways to make your home more energy efficient, which is the best first step to take when switching to solar power. “We tell people they really need to look at their building energy use,” says Sherri Shields, a spokeswoman for the Florida Solar Energy Center, a research institute of the University of Central Florida. “The more energy efficient you make your home, the less equipment you need to put on your roof.” If you’re purchasing your own solar panels, as opposed to leasing, it’s best to hire a local solar contractor or an electrical contractor that specializes in solar power. The contractor will take into account many considerations, including how much energy your home uses and potential sites for the panels. The type of roof you have, which direction your home faces and even nearby trees and other shade-producing obstructions all need to be factored in as well when designing a system. “It’s not just something cookie-cutter, out of the box,” Shields explains. Other things to keep in mind? Check with your insurance company to make sure your system will be covered under your homeowners insurance. Sometimes, a separate rider to the policy is required. Also, be sure all components carry the Underwriters Laboratories (UL) mark for quality and safety, and inquire about a truss-mounted system for roof panels — especially if you live in an area prone to severe weather. “We have to be especially careful in Florida,” Shields says. “If it’s not part of the roof structure, it’s going to come falling off.” Still in need of more information? A good basic guide for getting started is also available here, through the U.S. Department of Energy’s National Renewable Energy Laboratory. So put your plan together, go solar, and expect many sunny days in your future.

Wind Or Solar Which Is Better – The Reasons To Switch To These Alternative Energies

Article by Energy Saver

Wind Or Solar Which Is Better

Wind and solar energy are great renewable energy resources that do not have detrimental effects upon the environment. Due to the adverse effects on the environment by our current methods of obtaining fossils fuels and disposing of their waste byproducts, wind and solar energy are excellent forms of alternative energy.

The sunlight available to the globe is more abundant than the energy that can be consumed by all the people living on the planet. The locations that receive high concentrations of sunlight (meaning less cloud coverage and mountain range light blockage) would be a great place to start. There should be solar energy education for the people in these areas, such as desert regions and seemingly barren but developing countries, so they can make the most efficient use of the sun’s rays.

Wind renewable energy also has prime locations where it can be utilized. As T. Boone Pickens was informing us a couple years ago, there is a large wind tunnel stretching from Texas to the Canadian border where wind can be used as a significant energy resource. This quantity and quality of the wind speeds led him to call the United States the Saudi Arabia of wind.

In any case, if your property is applicable, wind and solar energy can be used for various home needs such as heating water, and certainly for generating electricity. This is true wherever the home is located.

The most attractive option for many people is solar energy. Although this is a more expensive start-up energy option than other sources, people are coming to grips with the evidence that using alternative energy is largely advantageous to the user and the environment.

For people considering wind and solar energy, subsidies and tax breaks are available in some states to offset the initial costs. The local utility company can also assist those interested. If new energy generating installations provide more than a home can use, the excess could be sold to the utility provider as a credit. Wind Or Solar Which Is Better

The beauty of solar energy installations is the immediate impact it has on the monthly electricity bill, and how much lower it will be. If enough equipment is installed to utilize the sunlight, you may never have to pay an electric bill again.

Another benefit of wind and solar energy installations is the impact it has upon the value of the home, should one decide to sell it. If you have interests in what your home would attain on the free market with renewable energy installations, call your local realtor. They should have good familiarity with the neighborhood going prices and the value of the improvement, and this should help them to provide you an estimate.

People are willing to pay more for houses that have installed wind and solar energy generators. This causes a significant increase in the value of the home. The National Association for Real Estate Appraisers has said that every dollar saved when using renewable energy increases the value of the home twenty fold.

To optimize the efficiency of green renewable energy sources used in the home, the home should be audited for its power demand and what can be done to reduce it. Are the demands for interior climate, lighting, and heated water efficiently under control? Is there the proper sealing and insulating foam in place around all closed windows and doors? Are the walls, attic, and basement insulated properly?

Knowing the power consumed isn’t necessary if steps aren’t taken to ensure that the power usage can be reduced. Power demand can be reduced by choosing the better rated Energy Star appliances. Improvements in all these areas will provide a lower energy demand, and this value will be more easily met with the wind and solar energy generators.

Increasing the energy efficiency of the home will lead to a home that greatly consumes less power. The immeasurable rewards of a greener world and larger bank account come from these energy efficiency improvements, compounded with the installations of wind and solar energy technologies.

The impact when the people of this country start taking into their own hands the way and the power source that their homes run will change the direction this country is going dramatically, and that is what needs to happen, when the rest of the world sees this, they will follow suit and the effect will be like a tsunami.
There is a great deal of information and enthusiasm today about the development and increased production of our global energy needs from alternative energy sources. Solar energy, wind power and moving water are all traditional sources of alternative energy that are making progress. The enthusiasm everyone shares for these developments has in many ways created a sense of complacency that our future energy demands will easily be met.
Alternative energy is an interesting concept when you think about it. In our global society, it simply means energy that is produced from sources other than our primary energy supply: fossil fuels. Coal, oil and natural gas are the three kinds of fossil fuels that we have mostly depended on for our energy needs, from home heating and electricity to fuel for our automobiles and mass transportation.
The problem is, fossil fuels are non-renewable. They are limited in supply and will one day be depleted. There is no escaping this conclusion. Fossil fuels formed from plants and animals that lived hundreds of millions of years ago and became buried way underneath the Earth’s surface where their remains collectively transformed into the combustible materials we use for fuel.
In fact, the earliest known fossil fuel deposits are from the Cambrian Period about 500 million years ago, way before the dinosaurs emerged onto the scene. This is when most of the major groups of animals first appeared on Earth. The later fossil fuels — which provide more substandard fuels like peat or lignite coal (soft coal) — began forming as late as five million years ago in the Pliocene Period. At our rate of consumption, these fuels cannot occur fast enough to meet our current or future energy demands.
Despite the promise of alternative energy sources — more appropriately called renewable energy, collectively they provide only about seven percent (7%) of the world’s energy needs (Source: Energy Information Agency). This means that fossil fuels, along with nuclear energy — a controversial, non-renewable energy source — are supplying 93% of the world’s energy resources.
Nuclear energy, which is primarily generated by splitting atoms, only provides six percent (6%) of the world’s energy supplies. And it is not likely to be a major source of world energy consumption because of public pressure and the relative dangers associated with unleashing the power of the atom. Yet, governments such as the United States see its vast potential and are placing pressure on the further exploitation of nuclear energy.
The total world energy demand is for about 400 quadrillion British Thermal Units — or BTUs — each year (Source: US Department of Energy). That’s 400,000,000,000,000,000 BTUs! A BTU is roughly equal to the energy and heat generated by a match. Oil, coal and natural gas supply nearly 88 % of the world’s energy needs, or about 350 quadrillion BTUs. Of this amount, oil is king, providing about 41 percent of the world’s total energy supplies, or about 164 quadrillion BTUs. Coal provides 24% of the world’s energy, or 96 quadrillion BTUs, and natural gas provides the remaining 22%, or 88 quadrillion BTUs.
It’s not so much that we mine fossil fuels for our consumption any more than it is to mine salt or tap water supplies way underground. The problems occur when we destroy ecosystems while mining it and while using it. Certainly, if there were a way that fossil fuels can be mined and used in ways that do not harm our ecology, then every thing will be okay… in a perfect world. What makes our world perfect is that, it really isn’t perfect according to definition. It is natural, with all things interdependent on each other to live, grow and produce. Fossil fuel mining and oil production can and has caused irreparable damage to our environment.
