RPS outside the US:
"- China will increase its use of renewables as part of a national plan to combat climate change, says the countryís environment minister Xie Zhenhua. .. he says the Chinese government will announce a national plan with concrete targets to improve energy efficiency by 20% by 2010 and to increase the proportion of renewables to 10%.
- Taiwan Power will spend NT$3.6 billion to install solar panels .. Taiwan imports 98% of its energy and the government wants renewables to generate 12% by 2025. .. The government owns 97% of Taipower, which generates three-quarters of the islandís electricity.
- The World Wind Energy Agency has welcomed the decision by the European Union to increase the continentís share of renewables to 20% by 2020." 7:58:26 AM
Texas Bid Could be First U.S. Offshore Wind Farm:
"Jerry Patterson, Commissioner of the Texas General Land Office, announced that the state has signed an agreement to allow an offshore wind-energy project in the United States to be built off Galveston Island. .. [Work begins immediately on] towers [to] gather data to determine exactly where the 150 MW wind energy development will be built on an 11,355-acre lease about seven miles off the coast of Galveston Island. ..
there is only one entity in Texas for an offshore wind developer to deal with -- the Texas General Land Office, according to the developers. Also, development within the 10.36 miles offers proximity to the state's electrical grid to carry wind-generated power to customers. Coastal winds also tend to rise during the day when the state's electrical generating capacity faces peak demand, therefore generating power when it's most needed. Plus, the gentle slope of the Texas Gulf Coast makes the development of an offshore wind farm easy. ..
Once the research is complete, the second phase of the lease -- the construction phase -- will begin. Construction is expected to cost as much as $300 million and could take as long as five years. W.E.S.T. plans to build a field of about 50 wind turbines to produce an expected 150 MW. The hub of each turbine will rise 260 feet above sea level. The turbine blades will be up to 55 yards long .. " Production is expected to last 30 years. 7:56:15 AM
South Africa: Cape green power plans:
"Eskom, local authorities and the private sector are set to launch renewable energy projects that will add at least 350 megawatts of electricity to the national energy grid. The Western Cape uses around 4 000MW of electricity daily, while the entire country uses around 34 000MW, which can go up to 40 000MW at peak demand [somewhat less than California]. In the recent past there have been regular power outages as Eskom battles to meet the growing demand for electricity.
The planned renewable energy projects include two 100MW wind
farms on the West Coast, a 100MW solar thermal
plant in the Northern Cape and a 50MW solar thermal
plant on the West Coast. .. The department is keen to launch projects that will ensure that 15 percent of the region's electricity needs will be met by clean and renewable sources by 2015."
Meanwhile the giant projects being coming online today
are not so green; coal dwarfs them all: "The two Western Cape liquid-fuel open-cycle gas turbine stations would collectively add another 1050 megaWatts of power to the national grid. Ingula Power Station .. will be a pump-storage hydro-electric scheme, with a generating capacity of 1330 mW. .. The 4200 mW coal
-fired power station in Lephalele would be named Medupi, meaning "the name that soaks parched land"." 7:41:23 AM
