  • Liquid electricity for cars of the future

    The reason why electric cars aren’t everywhere is simple — at the end of their range, they have to be stationary for hours while the batteries are recharged. This is a pity, because even cars recharged from ‘dirty’ power stations are three times more environmentally friendly than conventional vehicles. That’s because only 20 per cent…

  • US shifts $16 blllion toward renewable energy

    There’s some hope out there. The U.S. House of Representatives on Saturday passed a Democratic rewrite of U.S. energy policy that strips $16 billion in tax incentives away from Big Oil and puts it toward renewable energy sources like wind and solar power. The 786-page bill, passed in a rare Saturday vote, was a top…

  • Rooftop wind turbine for less than $A700

    An Australian inventor has come up with a novel rooftop wind turbine costing less than $A700 that has now received financial backing from the Western Australian government. Graeme Attey reckons just five of them could provide all power needs for an average suburban home.

  • Super-skinny solar cells soak up the sun

    The cost of producing solar panels could be sliced by more than 60% thanks to technology being developed by Australian researchers. Professor Andrew Blakers, director of the Centre for Sustainable Energy Systems at the Australian National University, says ‘sliver technology’ could reduce the price of solar power to below the current retail price of electricity….

  • New World Record Achieved in Solar Cell Technology

    A concentrator solar cell produced by Boeing-Spectrolab has recently achieved a world-record conversion efficiency of 40.7 percent, establishing a new milestone in sunlight-to-electricity performance. This breakthrough may lead to systems with an installation cost of only $3 per watt, producing electricity at a cost of 8-10 cents per kilowatt/hour, making solar electricity a more cost-competitive…

  • Spain requires new buildings use solar power

    Solar panels are now compulsory on all new and renovated buildings in Spain as part of the country’s efforts to bring its building rules up to date and curb growing demand for energy, ministers said on this week. Until now Spain’s building standards have done little in seeking to improve energy efficiency.“We have to make…

  • Wind and sun power cute commuter car

    The Venturi Eclectic, touted as an “autonomous energy vehicle,” gets its charge from wind and a roof of solar panels. The four-person ‘car’ boasts a 22-horsepower electric engine, powered by liquid-cooled NiMH batteries, and can reach a top-end speed of nearly 52kmh. Range is only 50km but that should be ideal for most town runs,…
