  • Ausra's zero-carbon power plants generate electricity at current market prices for fossil-fired power without the emissions caused by burning fuels. Low-cost thermal energy storage systems now under development by Ausra will allow solar electric power to be generated on demand, day and night.

  • One can see where the Minister is coming from. Current electricity prices are too low to fund new investment necessary to restore supply security. Average generation prices of around 12 c/kWh are less than half the cost of new coal-fired generation plant. The recently installed turbines, which are keeping the lights on over the Cape winter, produce power at a cost much higher than even the highest industrial tariff.

    A collaboration in Germany is about to explore whether a sizable distributed generation project can supplant centralized power plants. For this project - called SchwarmStrom - 100,000 mini gas-fired generators will provide heat and power in German homes and businesses, with a combined output of 2000 MW!

    "A Japanese trade ministry panel today proposed expanding the feed-in tariff to require utilities to buy electricity at a premium from hydropower stations, wind turbine and geothermal operators. Utilities may have to buy renewable power at between 15 yen (17 cents) and 20 yen a kilowatt hour, according to a report released in Tokyo today. The incentive program would run for between 10 and 20 years, it said. The government wants to supply 10 percent of the country's primary energy from renewable sources by 2020, compared with about 3 percent in 2007, according to the International Energy Agency. The proposed tariff compares with 5 to 7 yen a kilowatt hour utilities pay for nuclear power and about 8 yen for oil- fired generation, said Tomohiro Jikihara, an analyst at Deutsche Securities Inc. in Tokyo.

  • Light and compact lithium-ion batteries sound great for electric vehicles--aside from their historical tendency to catch fire. But recent advances in electrode chemistry have made them much safer. One of the first vehicles to use the new batteries comes from a Norwegian company, Think. By year's end, Think plans to start selling ultracompact electric cars with a range of more than 100 miles. A123 Systems of Watertown, MA, and Indianapolis's EnerDel will provide the batteries.

  • Remember when you were a kid and your parents made a big fuss about turning off the light when you left a room? Who knew that, besides adding to the monthly electric bill, keeping a single 60-watt lightbulb lit for 12 hours uses as much as 60 liters of water? According to researchers at the Virginia Water Resources Research Center, in Blacksburg, Va., fossil-fuel-fired thermoelectric power plants consume more than 500 billion L of fresh water per day in the United States alone.

    Increasing the amount of wind energy contributed to the electricity grid will not require large numbers of conventional coal- and gas-fired power plants to be kept on standby, according to a technical report published today. The report, commissioned by environmental groups including Greenpeace and Friends of the Earth, found that the UK's grid could cope with the variable energy input generated from wind farms.

  • mirrored solar dish that looks like a home satellite receiver, and produces 3.5 kilowatts of energy
  • Using its Stirling engine technology, Inifnia thinks it can eventually produce electricity 20 to 30 percent cheaper than today’s existing solar panels. And in times of peak energy demand—on a hot summer day, for instance—it could even be competitive with electricity from gas-powered or coal-fired plants.

    300 years after its invention, Stirling engines are coming to stay... and probably take a nice share of the Solar Power market. the cost perspective is also quite attractive. these structures cost now around $20 000 against 50 to $100 000 3 years ago.

  • SDG&E says that nearly 80,000 of its customers lost power, but by October 27th, power had been restored to all but 6,700 customers. Over the weekend, the utility expected to restore power to 97% of those affected, leaving only 2,400 without power
  • On Monday, October 22nd, the state's electrical grid operator—the California Independent Systems Operator (ISO)—declared an emergency when the Santiago Fire in Orange County caused two more high-voltage transmission lines to trip off-line. To avoid reduce stress on the power grid, the California ISO asked two utilities—Southern California Edison (SCE)and the San Diego Gas and Electric Company (SDG&E)—to reduce their electrical load by a total of 500 megawatts.

  • Xu Shisen put down the phone and smiled. That was Canada calling, explained the chief engineer at a coal-fired power plant set among knockoff antique and art shops in a Beijing suburb. A Canadian company is interested in Mr. Xu's advances in bringing down the cost of stripping out greenhouse-gas emissions from burning coal.
