Several months ago, I mentioned the Shimizu Corporation’s plan to place solar panels on the moon to generate renewable energy that would be transferred back to Earth and distributed along power lines. Shimizu Corporation’s hope was that they could begin working on their project sometime in 2020 when Japan planned to have a solar powered base upon the moon. (more…)

It should come as no surprise that in the wake of the Deepwater Horizon oil spill disaster, there has been a renewed push by environmental activists to embrace renewable energy options.

In a recent blog post, Richard Heinberg, senior fellow-in-residence at the Post Carbon Institute, discusses the root of the (more…)

For more than 40 years, scientists have dreamed of collecting the sun’s energy in space and beaming it back to Earth. Now, a host of technological advances, coupled with interest from the U.S. military, may be bringing that vision close to reality.

Despite the enormous promise of solar power, the drawbacks of the technology remain significant. People need electricity every day, around the clock, but there’s no part of the United States that is cloud-free 365 days a year — and no solar radiation at night. You have to find some way to store the energy for those sunless periods, and there’s not yet a large-scale way to do that.

Moreover, the best locations for solar arrays — the deserts of the American Southwest — are far from the centers of population, so even under the best of circumstances you’d have to send electricity many hundreds of miles through transmission lines that don’t yet exist.
