Proposal: In the short term focus on Methane reduction. Mid to Longer term focus on CO2 reductions. Why? Atul Jain, a U. of I. atmospheric scientist says; “Most of these methane abatement technologies can be quickly implemented with existing technologies,” “Because of its short atmospheric response time of about 12 years, methane concentrations will [...]

Farm lobbies, congress and others are getting in the way of the logical conclusion that energy from a food source is not as preferable as energy from a material grown for energy production. Ethanol based on corn is not only inefficient in terms of net energy produced but also [...]

Duh… Makes a lot of sense. If you only need to heat something 10-15 degrees (water temp around 55 degrees 30 feet) vs 30-50 (air temperature) degrees, it makes sense that it would take less energy to do it. That is my simple logic for geothermal energy. I was aware of it’s widespread use in Iceland, but wasn’t aware there was a residential system. At least one that seems to be getting some traction. From my limited research it seems like this company gets the most press.
