Solar thermal can solve the problems of the worlds energy?
According to this link Europe uses 4000 terawatt energy but in the deserts normally unusable North Africa and Middle East 630,000 terawatt fall unused. If solar thermal power stations covered the desert the size of Austria, she could feed the entire world. The technology is cheap and has a capacity to store energy for the purposes of the night. If all this is possible, why are we using the Earth are this clean source of cheap energy abundent? Http: / / www.spiegel.de/international/world/0, 1518,550544,00. Html
Solar thermal could do just that at affordable prices. Solar thermal can now produce electricity as low as 8 cents per watt, which would improve the economy of scale of mass production of solar energy components plant. 1% of the Sahara desert could feed the world. 1% of deserts in the American Southwest could supply the entire country. And solar energy photovoltaic efficiencey is not blocked at 10% of that response. It is closer to 20%. And that efficiency is improving rapidly and the cost of manufacturing solar panels diminishes just as quickly. Solar industry experts panel said they are just a few years from being at grid parity with coal and gas fired power plants. In fact, Nanosolar is already there, being able to produce solar panels Complete systems for less money than it takes to build a coal plant. And then there's the cost of coal and pollution away. http://www.brightsourceenergy.com/ "Nanosolar's founder and CEO, Martin Roscheisen, claims to be the leading manufacturer of panels solar power profitably sell solar panels for less than $ 1 per watt. This is the price at which solar energy becomes less expensive than coal. with a $ 1 per watt panel, "he said," it is possible to build $ 2 per watt systems. According to the Department of Energy building a new coal plant costs about 2.1 dollars per watt, plus the cost of fuel and emissions, he said. "from http://www.grinzo.com/energy/index.php/category/solar/ Concentrating solar photovoltaic power and solar thermal power plants in the south-west should be a big part of our energy future. Scientific American A Solar Grand Plan http://www.sciam.com/article.cfm?id=a-solar-grand plan shows how we could have 69% of solar energy in the U.S. in 2050 spending less in tax dollars we have spent building the Internet and high speed the information highway, and in about the same time, under 35 years. And by spending about 1 / 8 as a year during those years that we now give companies in oil subsidies.

What source of power! I hope we do not have to wait until oil and coal run out before we tackle that. "Thomas Edison, 1931 Solar thermal plants can store heat, which will generate steam driven electricity during the night. "Solar power plants heat such as Ausra to generate electricity by steam turbines driving the sun. Ausra solar concentrators boil water with light concentrated the sun and produce electricity at prices directly competitive with gas and coal power. "" Every American needs for electric power – the whole grid of the United States, night and day – can be produced with current technology Ausra using a square parcel of land 92 miles on a side. By comparison, less than 1% of the deserts of America, less land than currently in use in U.S. coal mines. "Some of the arguments against wind and solar power are meaningless, as the argument that they are too intermittent and not constant. There are areas in Denmark and Germany, who use more than 40 percent of their electricity from wind. From what I read, they are less concerned about the intermittency that we in the United States, even if we are not at 1 pecent yet. Why? Because we are told by the fossil fuel guys, hey, can not use wind, can not use solar energy, what about the intermittency. If the wind gets up to 40 percent of the electricity we use and solar gets up to 40 the electricity we consume, the other percentages we need electricity can be made from fossil fuel plants, which are still there. If they are run less at full power, they can last longer. This may be your electricity "Battery".

"Solar energy is the great leveler (unlike oil, which has been the great divider) between the haves and have-nots). Nobody owns the sun. It can not be drilled or mined or tied up in derivatives. "(See Here Comes the Sun, February 17, 2007, Commentary, Chipstocktrader.com) Green Wombat has several articles on solar thermal plants in California and Arizona. California has 9 small pilot plants that were built in the 80s and 90s. They produce 355 megawatts. Two large factories have been approved for the desert Mojave at 355 and 500 megawatts. Another is being built near San Luis Obispo to 175 megawatts. Two or three others are in the proposal stage, up to 800 and 900 megawatts for two of them. Http: / / blogs.business2.com/greenwombat / the Scientific American article: "The greatest obstacle the implementation of a renewable energy system in the United States is not technology or money, however. It is lack of public awareness that solar power is a practical alternative that can fuel transportation as well. Forward-looking thinkers should try to inspire U.S. citizens and their political leaders and scientists, on the incredible potential solar power. Once Americans realize that potential, we believe that the desire for energy self-sufficiency and the need to reduce emissions of carbon dioxide will lead them to adopt a national solar plan "" The huge reduction in imported oil would lower trade balance payments of $ 300 billion per year, assuming a crude oil price of 60 dollars per barrel (average prices were higher in 2007). "Together with wind and other renewable energies, we can move towards clean energy, while also improving our economy also. Http: / / www.setamericafree.org / blueprint.pdf A Blueprint for U.S. Energy Security document free SetAmerican above. The total of all oil-related external or "hidden" costs of 825 billion dollars per year. This total is almost double the figure allowed for the Defense Department in 2006. To put this in perspective further, it is equivalent to adding $ 8.35 the price of a gallon of gasoline refined from Persian Gulf. This will raise that figure to $ 10.73, making the cost of filling the gas tank a $ 214.60 sedan and an SUV $ 321.90. And then there is the oil of 300 billion dollars added to our trade imbalance per year. You think that makes a good economy? There is an incredible amounty misinformation about the potential of renewable energies.
