California Won't Take Any More Crap from OPEC
California Won't Take Any More Crap from OPEC
Imagine a vat of liquid cow manure covering the area of five football fields and 33 feet deep. Meet California's most alternative new energy. On a dairy farm in the Golden State's agricultural heartland, utility PG&E Corp began producing natural gas derived from manure, in what it hopes will be a new way to power homes with renewable, if not entirely clean, energy.

Its not a new way at all,
Its not a new way at all, gas from manure has been in use around the world for decades. It has just taken the oil price getting this high before some people are willing to try it on an industrial scale.
Methane from Manure
You got that right, Gutherie. This process also produces about one molecule of CO2 for every molecule methane. The CO2 is usually vented to the atmosphere.
Cows
Its not quite so bad as it sounds for CO2. It releases a lot, but an equal amount is absorbed by the grass grown to feed the cows, so its effect on CO2 by direct release is zero.
It does result in a lot of methane being released by the cows though, and finding somewhere to keep the livestock often means more deforestation.
Ross on BS
Wow climate science has found its energy resource.. it's BS. I'm not the least bit surprised!
There's me thinking that animal methane levels were a more serious threat to climate than human CO2 but our climate friends can overlook that matter if there's money in BS!
A new study “Use of U.S. Croplands for Biofuels Increases Greenhouse Gases Through Emissions from Land-Use Change” shows if we grow our fuel for vehicles that it produces double the CO2 to produce than using plain old fossil fuels... but there is a payback in 169 years!
Personally speaking I'd prefer to play football on my football pitches rather than cover them in eco-extremist BS.
