A car designed by teenagers that gets nearly 2000 mpg, white roofs for New York City, and how your DVR is jacking up your electric bill… this week’s green tech finds.

Puma’s “clever little bag” is biodegradeable: We mentioned Puma’s alternative to the shoe box back in April of 2010; PSFK reports that the bags will also be compostable (or, if you’re impatient, they’ll dissolve in water in a few minutes). (via Environmental Leader)
The 2000 mpg car? OK, not quite… this design by students at Kingdown School in Warminster, UK got a mere 1,980 mpg. That was more than enough for it to win the Mileage Marathon Challenge at Mallory Park track near Leicester. (via Inhabitat)

Home solar power offers affordable, safe electricity in Cambodia

Article: Home solar power offers affordable, safe electricity in Cambodia

In the developed world, renewable energy technologies have to compete with existing infrastructure based on fossil fuels or nuclear power. In the developing world, however, power grids and centralized power stations are often in poor shape or non-existent, so technologies like solar and wind play on a much more level playing field. Cambodia’s grid was relatively primitive from the start, and decades of warfare have degraded it even further; as a result, over 11 million people have no access to it.

In this kind of setting, solar power often works as a safe, affordable means of providing the most basic electric “luxury”: lighting.

100% green electricity potential exists in thirty US states

Article: 100% green electricity potential exists in thirty US states

Arizona has massive solar power resources. Texas, Kansas, and South Dakota together could power the whole country with wind. And the Rocky Mountain region holds vast potential for geothermal power generation. Traditional thinking in renewable energy development holds that we should tap these resources, and then move the power generated around via a next-generation national electric grid.

A new report from the Institute for Local Self-Reliance challenges this conventional wisdom, though, and makes the rather startling claim that 30 of the 50 US states could meet their own electricity demand entirely from in-state sources; seven more could generate 75% of their electricity needs this way. Thus, major (and expensive) improvements to the national grid may not be the most efficient use of resources.
