Springsure Creek Coal, a wholly owned subsidiary of Bandanna Energy, is developing the Springsure Creek underground thermal coal mine in Central Queensland, Australia. The coal mine is expected to produce approximately 11 million tonnes of coal per year and is expected to have a mine life of 40 years.

The micro inverters are used in the solar industry where you can easily install the components much better than the central inverters

Concentrating solar power (CSP) is an emerging technology that offers the potential to supply utility-scale peaking power competitively. In December 2008, a 1.5 MWe solar thermal central receiver system was declared operational by plant construction company Kraftanlagen Munchen. Although solar tower technology had been built as early as the 1970s and a second commercial tower is now close to completion (see REW magazine July/August 2008) the so-called Test and Demonstration Power Plant Julich, in Germany, is the world's first solar thermal power plant erected which uses air as the medium for heat transport. In all previous plants liquid media such as molten salt or oil have been used for the obvious reason of their high specific heat capacity, which in turn results in low volume flow rates and low pumping losses.

Expatriate Australian solar power company Ausra was one of the companies that featured heavily in my post on concentrating solar thermal power earlier in the year. California Governor Arnold Schwarzenegger has opened Ausra's first plant, a 5 MW plant at Kimberlina in central California (the first to open in 20 years) which will generate enough electricity during peak hours to power 3,500 homes. Ausra's next plant will be a 177 MW plant nearby in San Luis Obispo County. The SMH quoted Schwarzenegger as saying "This next generation solar power plant is further evidence that reliable, renewable and pollution-free technology is here to stay, and it will lead to more California homes and businesses powered by sunshine. Not only will this large-scale solar facility generate power to help us meet our renewable energy goals, it will also generate new jobs as California continues to pioneer clean-tech industry".

What if it were possible to bury carbon dioxide over a mile below a power plant in the second worst air basin in the United States? In 2011 the greenhouse gas will be pumped below a power plant in the southern San Joaquin Valley of California. Located in Kern County near Bakersfield, the Clean Energy Systems power plant is powered by different kinds of natural gas and oxygen. It produces five megawatts of energy, enough for 5,000 homes, but the carbon sequestration experiment will increase that to 50 megawatts.

Getting a solar system installed on your house is decidedly complicated. There is no centralized system, only contractors who you may or may not be able to trust. Prices for installation vary wildly, as do prices for the modules themselves. But in California, where things are getting a bit more consolidated and simplified, one retailer is trying to make solar easy. And it's Wal-Mart. Or, Sam's Club in nine California stores: Corona, Murrieta, Glendora, Ontario, La Habra, Chino, Long Beach, Fountain Valley, and Torrance.

We may be driving on air in the next few years. That is, we may be driving vehicles powered by compressed air, instead of gasoline or diesel fuel. Researchers Yu-Ta Shen and Yean-Ren Hwang of the National Central University in Taiwan have developed an air-powered motorcycle, which uses the energy in compressed air, rather than gas, to drive the motor.

The first wind farm in SA, which produces electricity from wind power, was switched on by minerals and energy minister Buyelwa Sonjica, in Darling, Western Cape on Friday, the Central Energy Fund (CEF) said. The R75-million national demonstration project is the first "green energy" initiative in the country to produce electricity from wind power on a commercial basis - this coming against the backdrop of the national energy emergency, it said in a statement.
