Solar Power Generation for a New World Order

House Solar Energy.net — Sun, 29 Jan 2012 11:05:33 +0000

Juan Trevino asked:

A home solar dish that activates a Stirling engine and moves a 3 kilowatt/hour power generator would make most electrical power generation and distribution grids, obsolete. This small, apparently insignificant Solar Generator installed at each of the 124 million households in America would deliver the energy that is needed to power up homes for heating, lights, cooking, water heater, TV sets and all the electrical amenities required to provide modern human comfort, now and years to come. A small equipment or appliance could solve a problem of gigantic proportions and would surely provide a more sustainable and new world order.

A series of articles along these topics will explore the solar power generation equipment, the centralized power generation and distribution system, demand for electricity and world growth, international energy agency position, sustainability of the electric industry and more related issues. These articles wish to make a modest contribution toward world sustainability and fairness in energy distribution. Finding investors that can contribute in developing the home solar power generator would be the largest plus for these articles.

Solar Equipment.- The Appliance

Homes in the US require an average of 25 to 35 kilowatts per day, or about one megawatt per month. Average homes need about 12 megawatts per year which may cost about 1,800 USD, every years. On the other hand, a home solar generator with an electrical storage system should cost less than $1,800 for the equipment and free sun power from then on. The solar generator receives about 10 hours of sun light per day, and can produce the temperature change needed to activate a Stirling engine. The Stirling engine in turn would drive a 3 KW hour power generator during sun light hours and deliver a direct current that is stored in a battery bank. Then the battery bank would provide on demand, 24 hour electricity to the home outlet.

Centralized Power Generation

Our current electrical power grids are the product of big business, big lobbyist and big government because they require large investments. An electrical power grid can be integrated using Nuclear, Coal, Gas, hydro power, or thermal turbines, to generate the steam which drives the power generator. The electrical energy is then sent though cables thousands of miles and delivered to homes, offices, and industrial buildings. Consumers need to be tied to electrical grids to have power. Having large number of consumers in a location maintains the electrical delivery systems within cost. This central power generation and distribution system, needs a large institutional infrastructure, including institutions such as the Department of Energy, a Nuclear Commission, an International Energy Agency, agencies to handle clean coal, liquid Natural gas to say the least. This complex power development model established in the past century and current today, increases entry cost to all societies and furthers development and underdevelopment of nations, in favor of countries that created the model and can afford the energy.

Power Plants require either carbon base fuels, uranium, thermal or hydo power as the energy source. Powerful special interests exists for the carbon based fuels, such as coal, natural gas and petroleum, to continue its usage and its proliferation. American foreign policy has been shaped to protects fuel supplies, and inhibit US participation in Green House Gas emission treaties. The centralized power generation model is so strong that it has elevated the initial investment for these plants, and position them at the Billion dollar marks. This situation has further contributed to the need for a World Bank, and an International Monetary Fund, who would fund those countries that need to buy Power Plants.

Freeing homes from electrical power grids implies that any home, anywhere, can power up if they have installed their $1,800 home solar generator, having the same human comfort that city dwellers now enjoy. . Governments or Power Companies would no longer need to invest 5 billion USD per Nuclear reactor to provide 1.5 Gigawatt capacity. Land used for the electrical transmission cable, would be recovered once the electrical power grids were dismantled.

Nevada Fails To Promote Solar Energy

House Solar Energy.net — Sun, 22 Jan 2012 21:35:38 +0000

As the nation’s capital creates legislation that is likely to transform the landscape of America from a fossil-fuel nation toward a renewable energy nation, states like Nevada – with its abundant sunshine, wide open spaces and concentrated population located in two major cities – stand to gain.

Nevada has already heeded the call of renewables. Plans for two coal-fired generating plants in White Pine County – by LS Power and Nevada Energy – have been canceled. Another coal-fired plant near Mesquite hit the skids earlier in the year.

Cap-and-trade, which threatens to make global warming emissions incrementally more expensive over time, is one of the bigger incentives to move away from coal, oil and natural gas. But another, a $3.2-billion provision hidden away in the economic stimulus bill passed in February, gives power companies in the West access to low-cost loans via the Western Power Authority that will help extend the nation’s transmission system to incorporate renewable energies like solar.

It’s a first step toward a smarter grid, and an essential step if renewable alternatives like solar and wind farms, commonly built well outside inhabited areas, are to reach the thousands in cities who need more energy, and would prefer it clean and green.

At least, this is the conclusion reached by a new Roper survey, which shows that almost 90 percent of Americans think new home construction should offer a solar option. This is up from 79 percent a year ago, according to the study commissioned by Sharp Electronics Corp.

The $3.2 provision, introduced by Sen. Harry Reid (D-Nv.), the current Senate Majority head, solves a long-standing Catch 22: investors are reluctant to finance renewable projects unless the transmission lines exist to transport it. But investors are also reluctant to invest in transmission lines until said renewable projects are up and running.

Up to now, the solution to this dilemma has been to build more fossil-fuel plants close to existing plants and tie the plant in to existing transmission. Coal-fired plants are cheap to build, domestic coal is believed to be plentiful, and is also inexpensive, allowing builders to recoup their construction costs quite rapidly.

But let’s go back to that plentiful coal. According to a report released by the U.S. Geological Survey (USGS) late in 2008, coal reserves in the Gillette, Wyoming field are – thanks to reevaluation and a redefining of the term “accessible” – a scarce 6 percent of previous estimates.

Another report from 2007, which dismisses previous methods of evaluating coal reserves, suggests that actual coal reserves across the country might be much smaller than previously supposed. In effect, say some experts, the U.S. only has enough coal to last about 20 years.

In light of this, it suddenly makes sense to build a $500-million line between Las Vegas and Ely to carry solar power. And both LS Power and NV Energy, having scrapped coal plans, are going ahead with transmission planning, because Nevada – with its 2005 mandate on utilities to provide 9 percent from renewables – is finally catching up, even if four years late.

Nevada’s Senate Bill 358, which will allow NV Energy to recover conservation losses through higher rates, is another incentive to go green, even though regional enviros regard it as a utility bailout.

The 2005 law mandates utilities like NV Energy and Nevada Power to produce 20 percent of power via renewables by 2015, and 25 percent by 2025. With the new power line a go, solar energy firms like First Solar should begin flocking to Nevada’s wide open spaces and 360 days of sunshine a year any time now.

Inmates Enjoy Solar Energy in Jail

House Solar Energy.net — Sun, 15 Jan 2012 06:56:38 +0000

Elysia Niemi asked:

Now, bright, clean, renewable solar energy is turning to its darker side; the Charleston County jail in South Carolina.

Unlikely perhaps, but the large flat roofs of Charleston County detention center, also known as, “The House”, which aims to improve its status as one of the nation’s most crowded inmate facilities with an ongoing $100-million expansion slated for completion next year.

The solar array will also improve power consumption figures, which already reach 4.25 million kilowatts a year, through regional utility S. Carolina Electric & Gas (SCE&G). This is expected to double on completion of the new facility.

No mention has been made where the panels are to be placed, but the logical assumption is that they will go on the new expansion, some 323,000 square feet in size (or only slightly less than the original detention center, built in 1966, and its 1993 expansion), largely because of the two previous sites older roofs.

The plan is to cover said roof with American-made solar panels to offset a portion of the detention center’s electricity needs, through a $1.1 million grant from the American Recovery and Reinvestment Act, or ARRA, which provides funding for governmental entities and schools to install energy efficiency devices like solar power. The grant competes for $2.8 million allotted to the state for renewable energy projects through ARRA.

The county believes the panels would more than pay for themselves through energy-cost savings, and some officials even speculate that the installation could help attract “clean energy” companies to the region. This would benefit S. Carolina’s citizens, who already hold a record as the sixth largest electricity consumers in the nation.

The solar photovoltaic “farm”, described as potentially producing 640,000 kilowatts a year, or enough to power about 5,300 homes, will also be responsible for eliminating 460 metric tons per year of carbon dioxide from coal-burning generation plants. This is the same as taking 84 cars off the road, or planting 11,785 trees, or preserving 104 acres of S. Carolina’s pine forests.

S. Carolina’s electricity generation mix currently consists of 61-percent coal-fired power plants, with the state’s electric cooperatives getting fully 80 percent of their electricity from coal. The solar proposal couldn’t have come at a better time, with Waxman-Markey in the wings and S. Carolina residents waking to the dangers of burning coal or piling the ash alongside streams and communities.

Largest Missouri Power Utility Going With Solar Energy

House Solar Energy.net — Wed, 13 Oct 2010 20:41:22 +0000

Ameren Corporation, the holding company for AmerenEnergy and Ameren UE, announced Monday, Dec. 1, that it plans to install solar energy systems at its headquarters in St. Louis and, eventually, another in Illinois.

Operating as Ameren UE, the company is one of the nation’s largest utilities, with 16,600 megawatts of generation and 2.4 million electric customers in Missouri and Illinois. AmerenEnergy is the risk management and energy marketing arm of the company. As a utility, Ameren also provides gas services, but its generation mix of 84 percent coal – and its status as the 5th largest coal consumer in the United States – creates a very bleak picture for the future of air quality in the region.

The initial solar installations will be either roof- or ground-mounted arrays, the company says, and range between 25 and 550 kilowatts. This is far from a large investment, particularly for a company the size of Ameren, but executives say the arrays will include cutting-edge solar technologies which will be used to evaluate solar’s enrichment value, at least in corporate terms.

Installation is slated for the fall of 2010 – again, nothing to write home about (many projects are up and running within three months of the announcement) – but a company spokesperson did say that, once the systems go online, Ameren will provide a range of information (available via the Internet) about its findings, which should help potential solar energy customers in Ameren’s service territory evaluate next steps.

AmerenUE will also be offering customers a rebate of $2 per watt (up to 25 kilowatts), or a maximum of $50,000 for solar electric systems installed after Jan. 1 of next year.

Ameren’s cautious venture in solar energy is reportedly a response to the state’s renewable energy mandate, Prop C, passed in 2008, which calls for utilities to use renewable energy for at least 15 percent of their generation mix by 2021 (with solar at least 2 percent of that renewable mix).

This will be quite a stretch for the company, which currently has only 2 percent vested in renewables, namely hydro, but the solar energy installation will, according to Ameren President Thomas Voss, help the company learn how to achieve the mandate.

Voss, who thinks that Missouri is not a very good geographic location for either solar or wind, apparently doesn’t realize that the wind-class values found in the northwestern part of the state (Class 3+) are fully as good as anything Minnesota – currently classed the “wind power capital” of the nation – can offer.

Solar insolation values are even higher, ranging up to 4.5 (on a scale of 2.0 to 6.5 in the continental U.S.). This is far greater than New Jersey (3.5), which currently challenges California for the role as the nation’s solar capital, based solely on installed solar power (2009).

Ameren, which was eyeing a new nuclear power plant until state regulators failed to nix a 1976 provision that prevented them from assessing ratepayers for the plant before it started producing energy, is at least exploring its renewable options. But this latest foray into solar energy is so cautious it’s like damning the technology with faint praise.

Where Does Solar Energy Come From?

House Solar Energy.net — Wed, 13 Oct 2010 20:41:07 +0000

Koz Huseyin asked:

Solar energy is making a big impact today. In the world we live, we have put major strain on natural resources. But, there is a renewable energy source, which is becoming a viable source to meet the needs of humanity, it is called solar energy. But, where does solar energy come from?

Imagine a home that is powered by a residential solar energy system. This home has electric 24 hours a day. You could watch TV all day, keep all the lights on, and not have to worry about an electric bill! So, how does this work? Where does solar energy come from?

In discovering where does solar energy come from, let us consider that we are in that solar powered home. Imagine for a moment that you want to watch TV. You press the televisions power button. Instantly like magic the TV comes to life. It comes on exactly as it would in a home powered by conventionally produced energy.

This energy is in the form of electric. It doesn’t matter whether it is from solar power, fossil fuels or even nuclear power. It is all the same – electric. The electric in residential solar energy systems doesn’t come from an external power station situated on Earth though. It gets more interesting!

The electric had to come from somewhere, and as we trace back, we find that the electric in the TV came from batteries. These are loads of batteries that hold onto this solar power, which we will come to in a moment.

A battery is like a cupboard. It holds things; most importantly it holds energy in the form of electric. This is important as we will see in a moment, as this source is not a 24 hour power, so we need a way to store it. Batteries make this possible, but where did this solar energy come from?

As we travel further, perhaps to the roof of the residential solar energy powered home or even somewhere else on the property, we will find solar panels. Solar panels are amazing gadgets, as they do something amazing.

Solar panels have a big area. They convert something into electric. But, how did they do this? Light is needed. And solar panels ingeniously convert light into electric. This light comes from a very big power station. In the case of Earth, this power is from our very own Sun.

The Sun is like a humongous power station that constantly does a reaction that lets out light. This light beams to Earth, and a solar powered home can make use of this to create electric around the home. It is truly marvelous, and is going to the basics that most of life on Earth uses – that is to utilize the power of the Sun. As plants do.

Solar Renewable Energy – Sun Power

House Solar Energy.net — Wed, 13 Oct 2010 20:40:57 +0000

It is no secret that the sun can be harnessed to provide a source of energy for homes and businesses.

The sun is a powerful star. It supplies us with energy, through a process called nuclear fusion, and sustains life on our planet Earth. Solar energy, or energy from the sun, has existed since prehistoric times when men would magnify the sun’s energy in efforts to start fires.

The sun is a valuable resource that radiates enough energy on the United States in one day to meet the nation’s needs for one and a half years. Since it is a free, clean and renewable source of energy, it is an energy source that will play a vital role in our future.

Using the sun’s energy for our energy source seems like an easy solution to having an energy supply forever. Harnessing the suns energy is where the problem lies. The sun’s rays shine all over the world and not in just one spot. Although it takes only 8 minutes for sunlight to travel to the earth, trying to catch the rays over such a wide area can prove to be tricky. Also, the energy in any one given place will vary due to factors, such as, clouds and weather conditions.

The history of using solar energy began in 1890′s when solar water heaters were used in the United States. Solar water heating requires a storage collector and a storage tank. Flat plate solar collectors are mounted on rooftops. Pipes carrying water are pumped through these collectors. The tubes are painted black so they will get hot quicker. As the heat is collected the fluid in the tubes get heated. A storage tank holds the hot liquid. This helps with central heating and cutting fuel costs. Solar heaters became popular when natural gas was expensive and burning wood and coals were burdensome. It’s popularity diminished with the discovery of an abundance of natural gas and oil deposits. Now they are making a comeback to replace the depleting fossil fuels that had taken its place.

Solar energy can be in the form of heat energy or light energy. The technology of photovoltaic, or PV as it is commonly called, converts the suns energy into electric currents through the use of solar cells. These electric currents can be used instantaneously or stored for later use. The PV cells consist of pieces of silicon under a thin piece of glass. They have both a positive and negative charge. Simple examples of this are the solar powered calculators that are common today. More complex examples are solar panels placed on roofs. This consists of using thin film solar cells as rooftop shingles, roof tiles, and even glazing for skylights. Unfortunately, the cells generate only about one sixth of the sun’s energy into electricity. This means bigger arrays are needed and along with this come larger costs.

Solar thermal power plants use the sun to heat fluid, which in turn, is transferred into steam similar to fossil fuel burning plants. The steam is transformed into mechanical energy in a turbine and electrical energy from a generator. The downfall is solar plants cannot produce energy on cloudy days.

It is expected the next few years will see millions of households using solar energy. As research continues and processes improve, using our sun as a renewable energy source will produce efficiency and cost savings. So, let the sun shine in and take full advantage of this warm energy source where you live.

drogbagoogle asked:

Queensland, Australia Brisbane, the capital city of the central business district has recently built the world’s largest solar powered sky bridge, October 4 and was open to the public.

Bridge called Kurilpa bridge, it is estimated that about 36500 people a week walking or cycling from the bridge over. Kurilpa bridge across the Brisbane River, connecting the central business district and the Brisbane City South Bank area of art.

Kurilpa the bridge looks like a knitting needle, it is not only the world’s longest pedestrian bridge, one of the bridge but also the installation of an advanced light-emitting diode (LED) lighting systems.

The energy from the sun to provide lighting systems can produce a wide variety of lighting effects. LED lighting systems will be used for a variety of festivals and the lighting along the river Lot. The bridge has 84 solar battery provides power for the LED light arrays, which portabale solar charger-Nissan 100 kwh electricity (100 kWh), the average annual output of power 38 megawatt-hours (38000 kWh). These energies entirely provide the energy needs of the flyover and most lighting needs.

Background About Solar Energy

Solar energy is the sun’s interior or the surface of sunspots continuous fusion reaction produces energy. Earth’s orbit, the average solar radiation intensity 1367w / ?. Circumference of the Earth’s equator as 40000km, in order to calculate the earth to obtain the energy up to 173000TW. At sea level on the standard peak intensity 1kw/m2, a point on the earth’s surface 24h of the annual average radiation intensity of 0.20kw / m², equivalent to a 102000TW energy, human beings rely on these energy to survive, including all other forms that can be renewable energy (except for geothermal resources), although the total amount of solar energy resources is equivalent to the energy used by humans are now ten thousand times, but the solar energy density is low, and it varies from place to place, because from time to time change, which is development and utilization of Solar facing a major problem. These characteristics make it solar charger in the whole role of integrated energy systems are subject to certain restrictions.

Although the solar radiation energy to the Earth’s atmosphere, only its 22 billionth of the total radiation energy, it has up to 173,000 TW, that is exposure to the sun to Earth per second of energy is equivalent to five million tons of coal. Earth wind energy, hydropower, ocean thermal energy, wave energy and biomass, as well as part of the tidal energy comes from the sun; even the Earth’s fossil fuels (such as coal, oil, natural gas, etc.) that is also fundamentally storage of solar energy down from time immemorial, it covered a broad range of solar energy is very large, narrow solar mobile charger is limited to solar radiation of light and heat, photoelectric and photochemical direct conversion.

Solar Water Heaters and Eligible Tax Credits and Rebates

House Solar Energy.net — Wed, 13 Oct 2010 20:40:43 +0000

Joseph Abrams asked:

Installing a new solar water heater is a rewarding purchase, buying into energy independence pays for itself. With Tax credits and Utility rebates the time is now to install new solar power and solar thermal home energy systems.

Solar Thermal is the practice of converting the energy from the sun hitting your roof into hot water for your entire home: Baths, Showers, Cooking, all heated with solar energy and stored in your homes new solar water heater, similar to a thermos with backup heating elements for none solar days.

In Tampa Florida we have the most solar days, if your electric bill exceeds 180 a month you should be buying into a new solar water heater today. Solar water heaters save 30-40% off your electric bill, couple this solar thermal system with a new High Efficiency air conditioner, thorough duct inspection and seal , and a new water conditioner and Reverse Osmosis system for the combined savings within 10years of a new car.

-Tax credits pay you back -Fuel savings reduced by 40-50% -Home energy smart

If your family ever needs more hot water than the sun can provide, or in long periods of inclement weather, most include a back up heating element which automatically takes over, insuring that you will always have all the hot water you need during none solar hours.

* Eligible for up to $2,000 federal Tax Credit * Eligible for up to $1,500 from State Government * Eligible for up to $450 rebate from utility company

This system is a whole house solution for family homes with at least 3 persons. We have larger systems as well, if you need two or more collector and a larger thermal storage tank we can still accommodate your family.

Massive savings, Massive Tax Credits, Massive independence from foreign oil. it pays for itself.

Why More People Should Buy Solar Panels

House Solar Energy.net — Wed, 13 Oct 2010 20:40:38 +0000

April Kerr asked:

The entire world is suffering from the deficiency of the natural resources. This is the reason why we should take more interest in utilizing the natural resources which are eternal and can never get reduced by regular usage. Solar energy is one of them. Instead of using the black energy generated from coal and petroleum the usage of green energy like solar energy should be endorsed.

The solar energy is sufficient enough for lighting the houses as well as other purposes like heating water etc. The solar panels are the tool that collects the solar energy. There are two different types of solar panels available. One of them uses the solar cells to transform the sunlight into electrical energy.

The other types of solar panels come with the thermal collectors which often are used to heat fluids of various types.

The cost of the solar panels depends on few factors. The size and capacity of the solar panels are important when it comes to calculating their cost. It also depends on the brand you prefer to choose for the solar panel. Now you need to check out whether you are getting the government decided rebates on the device or not. Moreover the durability of the solar panel is important because you cannot change it again and again.

Generally the solar panels come with a warranty period of 10 years. The normal expectation from them is production of ample power all through out the years. Some of the good branded solar panels come with an extended guarantee period of 25 years. The watt consumption of the solar panel is another important factor. The general trend is that the 1000 watt solar panel will produce around 1000 watts of electricity every hour.

The more the power generation capacity of the panel the more will be the price of it. The price can also fluctuate because of the cells that are used to manufacture the solar panels. This is quite important to check out which type of solar panel is going to suit your location and the space that you can provide to the system.

The solar panels are meant to be installed on the roof tops of buildings or as a stand alone. But while installing the solar panel you need to make sure that the panel is getting into direct contact with the sun light. This will make it equally productive in all parts of the year.

If there are any unnecessary things coming as an obstruction between the solar panel and the sun you need to remove them. These tips should be kept in mind while installing the solar panels if you wish to get the best results out of it.
