With all this bad news around, (though no, I haven't yet lost my faith in free markets), I have decided to post anything I come across that cheers me up.
Here's news of cheap yet efficient solar panels.
The idea of kite-generated electricity has always seemed very appealing.
From the Oil Drum: "While a goal of 100% of carbon-free electricity is probably unrealistic, (by 2020), it therefore seems possible to get pretty close to that, especially if nuclear and hydro are included in the mix (with wind). A plan that announced a specific goal of 40-50% of wind-generated electricity by 2020 and 10-20% of solar, with the appropriate feed-in mechanisms, demand guarantees for manufacturers and investment in the grid would therefore be realistic, make economic sense, and fulfill two major strategic goals: reduce carbon emissions, and lower fossil fuel demand."
