Fuel Efficiency in the US
A nice graphic comparing various passenger cars and alternative fuels. Two quibbles: - I don’t think the NASA crawler (used to transport the Space Shuttle) qualifies as a passenger car. - Why not include natural gas vehicles?
Predicting the Electric Vehicle Adoption Curve

Shale Gas: Not Clean, Either?
Not only are there serious questions about just how abundant natural gas from shale plays is, it now turns out that this “Cheap, Clean, Abundant, and Domestic” resource may turn out to only be domestic. In a draft paper, Cornell researcher Robert...
Community Solar Gardens
A new bill being considered in the Colorado legislature would create "Solar Gardens." Solar Gardens allow people to participate financially in owning part of a solar array even if they do not have a suitable site on their own property. My reading...
