Clean power source gets new attention, Boom is hinted for solar thermal plants

BOULDER CITY, Nevada --
At first, as he adjusted pumps and checked temperatures, Aaron Boucher looked like any technician in the control room of an electrical plant. Then he rushed to the window and scanned the sky, to check his fuel supply.
Boucher was battling clouds, timing the operations of his power plant to get the most out of patchy sunshine. It is a skill that may soon be in greater demand, for the world appears to be on the verge of a boom in a little-known but promising type of solar power.
It is not the kind that features shiny panels bolted to the roofs of houses. This type involves covering acres of desert with mirrors that focus intense sunlight on a fluid, heating it enough to make steam. The steam turns a turbine and generates electricity.
The technology is not new, but it is suddenly in high demand. As prices rise for fossil fuels and worries grow about their contribution to global warming, solar thermal plants are being viewed as a renewable power source with huge potential.
After a decade of no activity, two prototype solar thermal plants were recently opened in the United States, with a capacity that could power several big hotels, neon included, on the Las Vegas Strip, about 20 miles, or 32 kilometers, north of here. Ten more power plants are in advanced planning in California, Arizona and Nevada. . . .

Rising energy costs? Tax incentives to install solar heating systems? Haven't we been here before? Yes and no.
SOLAR IS making a comeback for the first time since the late-1970s. To a certain extent, it sounds like the past repeating itself, with energy prices up and tax incentives to install solar heating systems. Some things, however, may have changed to help alternative sources of energy move at least a bit more to the center of the stage.
So what's happening now that's causing a rebirth of solar energy? Here's a number of questions we had and the answers we found.
I've heard plenty of stories about solar hot water systems put in during the Carter administration. What I've heard doesn't exactly fill me with confidence.
We've heard those stories, too, when fly-by-night companies were busy selling tax credits instead of installing quality equipment. But a couple of things are different today.
A big difference comes by way of the Solar Rating and Certification Corp. The nonprofit group provides third-party testing, rating and certification of solar collectors and solar domestic water-heating systems . . . .

- Dynegy putting solar to the test / Study aims to cut fuel costs and emissions
Houston Chronicle 11-14-2008
Houston-based Dynegy is working with a power industry research group to test the feasibility of using solar power to reduce fuel costs and cut emissions at existing electric power plants. The study won't involve construction of the solar equipment - at least not yet - but rather will examine the economics of using solar power to generate steam to spin turbines at Dynegy's 578-megawatt Kingman, Ariz., plant.
Existing solar technology is not considered cost-competitive with other sources of electric power. Photovoltaic technology, which turns sunlight directly into electric current, costs more than 20 cents per kilowatt-hour, compared with about 5 cents per kwh for coal.
But the Dynegy project, which is being done with the Electric Power Research Institute, will study using large arrays of mirrors to direct solar energy to heat water into steam. That steam, along with steam created by burning natural gas, would drive electric turbines.
"These hybrid power plants' will combine the low-cost reliability of existing fossil power plants with the environmental benefit of renewables and help companies meet federal and state mandates to reduce their emissions of air pollutants and greenhouse gases with renewable energy," said Bryan Hannegan, vice president of environment and generation at the Electric Power Research Institute.
Advantages over wind
Twenty-seven states set renewable energy standards, including Texas, where power companies mainly use wind power to meet the renewable goals . . . .
- The Changing Shape of Renewables Technology
Electrical Construction & Maintenance 01-01-2008
Until recently, breakthroughs in renewable electric energy technology debuted in relative obscurity. With high up-front costs and rates of return spanning decades, these technologies were deemed "alternative" or non-traditional, to be used only in cases of extreme environmental concern or high-end model projects. However, increased awareness about global warming, unprecedented prices per barrel for oil, generous utility rebates, the burgeoning popularity of Washington, D.C.-based United States Green Building Council's (USGBC) Leadership in Energy and Environmental Design (LEED) green building rating system, and mandated green practices through legislation at the federal level have converged to place renewable energy technology at the forefront of electrical construction in the residential, as well as - more remarkably - the commercial and industrial markets.
Signed into law December 19, the Energy Independence and Security Act sets increasing renewable electric energy provisions, essentially quintupling the use of renewable fuels by 2022. In Title IV, the law requires improved federal and commercial building energy efficiency, with green building standards for new federal buildings, as well as a zero net energy initiative to develop technologies, practices, and policies - with the goal of having all commercial buildings using no net energy by 2050. Furthermore, Title VI focuses on research and development (R&D) for alternative energy sources, such as installing and maintaining solar energy equipment and R&D to improve technologies to store solar power, as well as R&D for technologies to locate and develop other alternate energy sources.
Green design and construction has become an increasingly lucrative investment and a powerful selling tool. Growing worldwide and domestic use of renewable electric energy is expected to rival more traditional fossil fuel energy sources within the next decade. This demand has, for lack of a better word, fueled research and development efforts for more efficient, less expensive renewable energy production and storage, particularly in the solar- and wind-energy markets.
The global market for conventional solar photovoltaics (PV) is predicted to grow from $12.9 billion in 2007 to $32.3 billion by 2012, according to a technical market research report by BCC Research, Wellesley, Mass. . . .

When Capt. John Ericsson towed the Admiralty-barge from Somerset House down the Thames, at the rate of ten miles an hours, with his screw-propeller steam-launch, in 1837, the watermen that lined the river banks were amazed. Ericsson waited impatiently for the verdict of the Board of Admiralty, who were to give an opinion on his substitution of the . . .

BAYARD WEBSTER, New York Times. Jul 5, 1974. p. 31 (2 pages)
While the sunne shineth-make hay. John Heywood  The sunlight that most people take for granted makes it possible to grow all the plants on earth, make skyscrapers appear to be spires of gold, produce air currents that turn 100,000 windmills and make dewdrops sparkle like diamonds. Energy from the sun is captured in a series of mirrors at a station in the French Pyrenees, above. At right is a statue surmounted by a representation of a solar mirror. The statue is in Osaka, Japan. Diagram shows domestic system for using solar heat.
