In an ambitious scheme than even industry proponents seem skeptical of, Britain has unveiled plans to power every home in the country via off-shore wind farms by the year 2020. Right now the UK produces approximately half a gigawatt through this method of power generation, enough to provide 2% of the country's electricity, but nowhere near the 33 gigawatts called for in business secretary John Hutton's proposal. According to the British Wind Association Trade Group, while more offshore farms are always welcome, it is far more reasonable to expect a 20 gigawatt output by 2020 -- the bottleneck, apparently, is in procuring an adequate number of turbines. Another issue is the economic cost of wind power, which continues to exceed that of fossil fuel-based alternatives; luckily for the Brits, favorable exchange rates should help them pick up some American-made turbines on the cheap.

Clogged highways and frustratingly waiting while your gas needle plummets to empty usually doesn't conjure up thoughts of green, but it seems like these very roads could become the source of a lot more energy. Several recent student designs have proposed that major roadways be retrofitted with various forms of wind energy collection devices, ranging from overhead turbines that collect energy from quickly-moving cars below to barrier panels (pictured after the jump) that harness the wind from closely passing vehicles moving in opposite directions. Ideally, the wind energy could then be sent back out to the grid to power nearby communities, light-rail transportation systems, or even intelligent billboards. Of course, most of these ideas are still in the research phase, and even if proven feasible, we can't imagine the up-front costs (or inconveniences of installing these things) to be minor, but we're sure that government subsidies should be able to to lend a helping hand.
