Yes, the economy could soon run on (mostly) renewable power

A study from the National Renewable Energy Laboratory demonstrates that an energy mix that is 80 percent renewable in 2050 could operate fine. If only we had the will to create it.

U.S. military kicks more ass by using less fossil-fuel energy

Wisconsin hospital is powered by beer and cheese

Gundersen Lutheran Hospital, in La Crosse, Wis., aims to be energy independent by 2014. Hospitals use a ton of energy, so that’s a tough goal to meet. But Gundersen is getting there by piggybacking on Wisconsin’s best-known industries: beer and cheese. Beer and cheese, while delicious, both slough off a lot of gas while they’re being made. (Not to mention after they’re consumed.) The hospital system has been sourcing biogas from a local brewery and from a dairy farm that makes mascarpone and fresh mozzarella cheese. And recently the system started getting gas from a La Crosse landfill, as well.

Power in numbers: Crowd purchasing brings clean energy within reach

Buying wind power or giving your house an energy efficiency facelift can be an expensive proposition. But it’s less so if you team up with a bunch of like-minded friends.

Obscure-but-awesome energy law getting shivved by natural gas lobby

George W. Bush signed a law requiring that new federal buildings gradually eliminate consumption of fossil-fuel energy by 2030. Now the natural gas industry is trying to kill the rule.

Meatpacking plant turns into net-zero-energy vertical farm

Soon, a former meatpacking plant in Chicago will replace carcasses and rendering vats with bakers and brewers and fish farmers and mushroom growers. The Plant (ho ho, a double meaning!) is gathering together a bunch of food-makers to create a self-sustaining system in the 93,500-square-foot abandoned space. As Fast Company reports, a former meatpacking plant is the perfect place to start a food business of this kind: It already contains “food-grade materials” which are safe for food preparation.
