    MADRID — On one side, angry coal miners are striking to prompt the government to save their jobs from a torrent of inexpensive imports. On another, the once-booming solar power industry complains that it is being crippled by the mere prospect of an end to generous state subsidies. The natural gas and nuclear industries are having problems of their own. Meanwhile, the shortfall accumulated since 2000 between the cost of power generation in Spain and what regulated rates bring in from consumers is expected to reach €20 billion, or $26.7 billion, by the end of the year — a bill...

    ROME (Reuters) – Italy Tuesday seized Mafia-linked assets worth $1.9 billion -- the biggest mob haul ever -- in an operation revealing that the crime group was trying to "go green" by laundering money through alternative energy companies. Investigators said the assets included more than 40 companies, hundreds of parcels of land, buildings, factories, bank accounts, stocks, fast cars and luxury yachts. Most of the seized assets were located in Sicily, home of the Cosa Nostra, and in southern Calabria, home of its sister crime organization, the 'Ndrangheta.

    A new process that simultaneously combines the light and heat of solar radiation to generate electricity could offer more than double the efficiency of existing solar cell technology, say the Stanford engineers who discovered it and proved that it works. The process, called "photon enhanced thermionic emission," or PETE, could reduce the costs of solar energy production enough for it to compete with oil as an energy source. Stanford engineers have figured out how to simultaneously use the light and heat of the sun to generate electricity in a way that could make solar power production more than twice as...

    Scientists from the California Institute of Technology (Caltech) have developed a new solar cell that they hope will cost a tiny fraction of current production. The new cells consist of tiny silicon wires that measure a mere 1-micron in diameter. These wires are embedded lengthwise and perpendicular into plastic plates where they convert light into electricity at an exceptional rate of efficiency. Any light that is leftover bounces around inside the wire matrix until it finds another wire that can absorb it, thus nearly all the light is captured and converted into electricity. Professor Harry Atwater at his namesake research...

    Government subsidies for solar energy in Germany have reached absurd proportions, as ordinary consumers pay out billions to support solar power. Now plans to reduce the subsidies are encountering massive resistance from the industry and a number of German states, which benefit from the current arrangement. Stuart Brannigan believes that the subsidization of solar power practiced in Germany is extremely exaggerated. Brannigan, a British citizen, says that it's "absolutely necessary" that it be drastically reduced in size. It's a surprising remark, considering that Brannigan is the European managing director of Yingli Green Energy, a Chinese solar energy company which largely...

    PUERTOLLANO, Spain — Two years ago, this gritty mining city hosted a brief 21st-century gold rush. Long famous for coal, Puertollano discovered another energy source it had overlooked: the relentless, scorching sun. Armed with generous incentives from the Spanish government to jump-start a national solar energy industry, the city set out to replace its failing coal economy by attracting solar companies, with a campaign slogan: “The Sun Moves Us.” Soon, Puertollano, home to the Museum of the Mining Industry, had two enormous solar power plants, factories making solar panels and silicon wafers, and clean energy research institutes.

    US researchers have designed a new silicon-based solar cell which uses 100 times less silicon than conventional photovoltaic devices. The system relies on the geometry of the silicon being reconfigured from a flat wafer to arrays of tiny silicon rods aligned vertically on the cell.Currently silicon solar cells are fabricated on brittle wafers of silicon around 100-200 micrometres thick. While these can be relatively efficient in terms of conversion of light energy to electrical energy - up to 25 per cent - relatively large quantities of silicon material are needed, which is a significant part of the cost of the...

    WHILE physicists struggle to get quantum computers to function at cryogenic temperatures, other researchers are saying that humble algae and bacteria may have been performing quantum calculations at life-friendly temperatures for billions of years. The evidence comes from a study of how energy travels across the light-harvesting molecules involved in photosynthesis. The work has culminated this week in the extraordinary announcement that these molecules in a marine alga may exploit quantum processes at room temperature to transfer energy without loss. Physicists had previously ruled out quantum processes, arguing that they could not persist for long enough at such temperatures to...

    AMBOY, Calif. — Senator Dianne Feinstein introduced legislation in Congress on Monday to protect a million acres of the Mojave Desert in California by scuttling some 13 big solar plants and wind farms planned for the region. But before the bill to create two new Mojave national monuments has even had its first hearing, the California Democrat has largely achieved her aim. Regardless of the legislation’s fate, her opposition means that few if any power plants are likely to be built in the monument area, a complication in California’s effort to achieve its aggressive goals for renewable energy.

    After years of over promising and under delivering, the solar Industry is finally starting to show some interesting developments which have the potential to make solar power as cheap as fossil fuel on a cost-per-watt basis within five years. Getting us to that state, called grid parity, would require solar companies to produce power for around $1 a watt. Is it possible anytime soon? Many analysts think so and the target date being touted around is 2015. The reason for this fresh optimism is a mixture of technological development and simple economics. Traditional conductive materials make up 40% to 50%...

    Why are we ignoring things we know? We know that the sun doesn't always shine and that the wind doesn't always blow. That means that solar cells and wind energy systems don't always provide electric power. Nevertheless, solar and wind energy seem to have captured the public's support as potentially being the primary or total answer to our electric power needs. Solar cells and wind turbines are appealing because they are "renewables" with promising implications and because they emit no carbon dioxide during operation, which is certainly a plus. But because both are intermittent electric power generators, they cannot produce...

    A new type of solar energy collector concentrates the sun into a beam that could melt steel. Researchers say the device could revolutionize global energy production. The prototype is a 12-foot-wide mirrored dish was made from a lightweight frame of thin, inexpensive aluminum tubing and strips of mirror. It concentrates sunlight by a factor of 1,000 to produce steam. "This is actually the most efficient solar collector in existence," said Doug Wood, an inventor based in Washington state who patented key parts of the dish's design - the rights to which he has signed over to a team of students...

    "Liquid Metal" at the Center of IBM Innovation to Significantly Reduce Cost of Concentrator Photovoltaic Cells ARMONK, NY, May 15, 2008 IBM today announced a research breakthrough in photovoltaics technology that could significantly reduce the cost of harnessing the Sun's power for electricity. By mimicking the antics of a child using a magnifying glass to burn a leaf or a camper to start a fire, IBM scientists are using a large lens to concentrate the Sun's power, capturing a record 230 watts onto a centimeter square solar cell, in a technology known as concentrator photovoltaics, or CPV. That energy is...

    Innovalight's Silicon Ink by Joe Kwiatkowski, Physicist, Imperial College London London, UK [RenewableEnergyWorld.com] The last quarter of 2007 was an exciting time for the Silicon Valley start-up Innovalight: first a successful finance round that drew US $28 million of new capital, then the accolade of being amongst Red Herring's top one hundred innovators. Why the interest in Innovalight? Because of its remarkable claim to be able to print thin-film silicon solar cells. Printing is generally a low-cost and high throughput process, in stark contrast to conventional methods used to produce amorphous and crystalline silicon solar cells. As such, Innovalight claims...

    Solar power, the holy grail of renewable energy, has always faced the problem of how to store the energy captured from the sun’s rays so that demand for electricity can be met at night or whenever the sun is not shining. The difficulty is that electricity is hard to store. Batteries are not up to efficiently storing energy on a large scale. A different approach being tried by the solar power industry could eliminate the problem. The idea is to capture the sun’s heat. Heat, unlike electric current, is something that industry knows how to store cost-effectively. For example, a...
  • Frito-Lay solar system puts the sun in SunChips, takes advantage of renewable energy

    Modesto Bee ^ | April 3, 2008
    The Frito-Lay plant in Modesto will start using a new ingredient of sorts to make its SunChips brand snack — the sun. The company is installing a football field-sized farm of solar collectors next to its plant in the Beard Industrial District, with plans to flip the switch on Earth Day. The solar field is made up of large curved mirrors that move with the position of the sun, focusing the heat into tubes of glass filled with water. That water is directed into the plant's boiler system, where it will be converted into steam to heat the oil used...

    It's a green energy company, producing polysilicon destined for solar energy panels sold around the world. But the byproduct of polysilicon production -- silicon tetrachloride -- is a highly toxic substance that poses environmental hazards. "The land where you dump or bury it will be infertile. No grass or trees will grow in the place. . . . It is like dynamite -- it is poisonous, it is polluting. Human beings can never touch it," said Ren Bingyan, a professor at the School of Material Sciences at Hebei Industrial University.

    A 'sun tower' is one of the concepts being considered by researchers Scientists are assessing the possibility of embarking on a space engineering project that would eclipse the effort to construct the International Space Station. Researchers from Europe, Japan and the US are considering the viability of building giant solar panels in a low earth orbit that would supply cheap, inexhaustible energy to industry and homes. Building a huge array outside the Earth's atmosphere would have the advantage of having no clouds to interrupt the flow of solar energy to the arrays. Yet the sizeable downside would be the...

    TACOMA, Wash., Oct. 22 — The sun was shining for a change, which was good news for Richard Thompson, known throughout these parts as Solar Richard. “Pennies from heaven,” Mr. Thompson said as his electric meter spun round — in reverse. Not that a shining sun is required for the meter to spin backward. An overcast sky does the job. The meter just spins a bit more slowly. That would be the meter attached to Mr. Thompson’s house, painted sunshine yellow with a large solar panel out front next to the bedraggled remains of giant sunflowers — “organic solar trackers,”...

    Cool Earth Solar ^ | Solar Power 2006 Presentation | Eric Cummings
    Three years ago our top scientists and Nobel Prize winners met in Washington in search of a solution to energy-related Global Warming. Four points came from the meeting: - there is no solution available - yet we must implement one by 2050 - the only power source that presents a viable solution is solar - but solar energy is currently far too expensive. Cool Earth was formed to solve this problem. Now. With currently available technology. We are working to reduce the cost of solar electricity by a factor of 25, making it cheaper to produce than energy from coal...

    The trade association for the nuclear power industry recently asked 1,000 Americans what energy source they thought would be used most for generating electricity in 15 years. The top choice? Not nuclear plants, or coal or natural gas. The winner was the sun, cited by 27 percent of those polled. It is no wonder solar power has captured the public imagination. Panels that convert sunlight to electricity are winning supporters around the world — from Europe, where gleaming arrays cloak skyscrapers and farmers’ fields, to Wall Street, where stock offerings for panel makers have had a great ride, to California,...

    HUMANS are just one of the millions of species on Earth, but we use up almost a quarter of the sun's energy captured by plants - the most of any species. The human dominance of this natural resource is affecting other species, reducing the amount of energy available to them by almost 10 per cent, scientists report. Researchers said the findings showed humans were using "a remarkable share" of the earth's plant productivity "to meet the needs and wants of one species". They also warned that the increased use of biofuels - such as ethanol and canola - should be...
