Advances in solar electricity

Last month, Bill McKibben reviewed a handful of books in the New York Review of Books, including James Lovelock’s Revenge of Gaia and, somewhat in passing, Travis Bradford’s Solar Revolution: The Economic Transformation of the Global Energy Industry. I’m reminded of this because of an article from yesterday on a “breakthrough” in solar cell technology. McKibben reports that Bradford fairly convincingly predicts significant advances in solar electric technology, as well as significant drops in the cost of pv systems, mostly because of major investments in R&D in Japan and Germany. Well, the prediction might be even better than Bradford expected–this short article says that the National Renewable Energy Lab has verified the claim of Boeing-Spectrolab that it is created a solar cell with over 40% efficiency in converting sunlight to energy. This is up from, it says, most of today’s cells which are only 12%-18% efficient.

Overshoot, Collapse, and Creating a Better Future

In 2016, Earth Overshoot Day happened on August 8—the day when we’ve exhausted the planet’s resources for the year, and are essentially borrowing from future years to maintain our existence today.Perhaps you celebrated this day with a counter-solution: a vegetarian meal, telecommuted, or turned off the air conditioning. There’s a lot more you could be […] Read More

Save Energy & Money This Winter: Seal Up Your Drafty House

Unless you’ve taken special preventative precautions, it’s likely that on cold days much of your house’s heat pours out through your (closed) windows. Most houses—especially old houses—have drafty, uninsulated windows that do little to prevent heat from dumping out into the cold night. Even if your windows aren’t drafty, the expensive heat your furnace has […] Read More
