Large-scale solar power is beginning to take on the job of meeting the demands made by California's air conditioners for electricity. Pacific Gas & Electric and Brightsource Energy today announced they have expanded a series of solar power contracts for a total of 1,310 megawatts of electricity - enough to power 530,000 California homes during peak hours with energy from the Sun. Completion of the first project will nearly double the amount of solar thermal electricity produced in the United States.

Der Spiegel has an interview with Boeing's "chief environmental strategist", Billy Glover, on prospects for biofuel use in air transport (he's very optimistic, but short on detail) - Algae Could 'Supply Entire World with Aviation Fuel'. SPIEGEL ONLINE: Mr. Glover, given the current low price of oil, why would airlines still even be interested in biofuels? Glover: Indeed, the oil price has changed rapidly. But it has done that many times before and it will continue to do so. Even today, the highest operating expense for an airline is fuel. It remains a priority to find a way to mitigate that situation. That is why Boeing is trying to open up this avenue of alternative fuel. It can help that situation while having a better environmental performance at the same time.

What do you do if you build a wind farm smack dab in the middle of a major bird migration route, and want to avert the anger of conservationists? Put up a radar system that's designed to shut down the entire thing when it detects a mass of birds on the way. That's what's been done at the 202 MW Peñascal Wind Farm in Texas: System Detects Birds Approaching Four Miles Away The system uses radar originally developed for NASA and the US Air Force to detect birds as far as four miles away, The Guardian reports. When it picks up the approaching birds, it analyzes the existing weather conditions and determines in real time whether those birds are in danger of flying into the blades. The system then automatically restarts the turbines when the birds have passed.

A solar water heater can save around $450 in a year and can keep tons of CO2 emissions out of the air. If that is multiplied by 80 millions houses in the U.S., just imagine how clean we can keep our environment.

The building's design should be one that takes into account as many green aspects as possible. From using natural lighting to reduce the amount of electricity, to good air ventilation to reduce the need for energy for cooling, the building should be built to save money and resources.
