It's a gas

Evidently Alameda's municipal electric company, Alameda Municipal Power (AMP), is known as "The Greenest Little Utility in America." I wasn't aware of the moniker for Alameda, but I did know that AMP tries pretty darn hard to keep its power sources as green as possible.

Yesterday, a new landfill gas to energy station kicked off in Half Moon Bay at Ox Mountain Landfill. The energy generated from the conversion will help to power homes in both Alameda and Palo Alto (which also has a municipally owned electric company).

According to a press release:

Landfill gas is created when organic waste in landfills decomposes, producing methane-the primary ingredient in natural gas and a greenhouse gas. The landfill gas to energy plant captures the methane and turns it into electricity for use by residential and business customers. Converting landfill gas to energy prevents the release of greenhouse gases and creates electricity from a renewable, affordable source-reducing the need for power created from fossil fuels.

AMP currently has two other landfill gas to energy sources in its power portfolio and will be adding a fourth later this year. After the fourth is added almost 22% of our power will be generated from garbage.

Now if only we can find a way to harness cow farts into power...

Regular Light Bulbs Made Super-efficient With Ultra-fast Laser

An ultra-powerful laser can turn regular incandescent light bulbs into power-sippers, say optics researchers at the University of Rochester. The process could make a light as bright as a 100-watt bulb consume less electricity than a 60-watt bulb while remaining far cheaper and radiating a more pleasant light than a fluorescent bulb can.
