  • Ethanol, for instance, is an alcoholic biofuel easily distilled from sugary or starchy plants. It has been used to power cars since Ford’s Model T and, blended into conventional petrol, constitutes about 10% of the fuel burned by America’s vehicles today.

solar cost

shared by sokolkyl00 on 30 Sep 13 - No Cached
  • If the trend continues for another 8-10 years, which seems increasingly likely, solar will be as cheap as coal with the added benefit of zero carbon emissions. If the cost continues to fall over the next 20 years, solar costs will be half that of coal.
  • When applied to electricity prices this predicts that solar generated electricity in the US will descend to a level of 12 cents (7 pence) per kilowatt hour by 2020, possibly even 2015 for the sunniest parts of America.

shared by charlesjos00 on 03 Oct 13 - No Cached
  • Photovoltaic cells are made of at least two layers of semiconducting material. The first layer has a positive charge; the next layer has a negative charge. When sunlight strikes the cell, the semiconducting material absorbs photons from the light. This process frees electrons from the negative layer, which move to the positive layer. This flow of electrons constitutes an electric current, which can be captured in a circuit connecting the two layers. The electricity generated by a photovoltaic cell can be used directly, stored in batteries or sold back to a utility company.

    yes but they will if you get enough of them they will outlast the fossil fuels but as this all burns out it can work as we will also by finding new planets we could find more and more fuels i expect this would . happen within a few decades of our time. as this might happen we could probably be able to live on other planets by then so when the sun actuly goes out we will be prepared

  • The amount with in the earth’s surface contains 50,000 times more energy than all the oil and natural gas resources in the world.
  • To get that heat, water is pumped down an “injection well”. Then it filters through the cracks in the rocks where they are at a high temperature. The water then returns via the “recovery well” under pressure in the form of steam. That steam is captured and is used to drive electric generators.

  • Solar power generators offer a no-emission alternative to ones that use fossil fuel. These generators come in small, portable sizes for temporary power or larger arrays for permanent energy production.
  • availability of sunlight given local weather conditions and the resilience of the photovoltaic cells when purchasing a solar generator.
  • Most photovoltaic cells rely on silicon crystals to generate power. Demand for silicon has driven its price higher, meaning a solar generator can require a sizable initial investment. In fact, SolarBuzz notes that 45 percent of solar cell cost comes from the silicon wafer. Typical 2 kilowatt solar generators cost from $16,000 to $20,000.

  • Solar generators powerful enough to supply electricity for a whole home also require a lot of space, with roof-mounted panels needing at least 50 square feet and possibly as much as
