Comparison of Grid-Connected and Off-the-Grid Houses

November 26, 2014 by Willem Post

Energy efficiency for buildings wasn't an issue until after the increase of crude oil prices in 1973. Building owners, seeing increases in energy costs, consulted engineers to make energy surveys of buildings, which, after implementing recommendations, usually resulted in decreases of energy consumption.[read more]

Solar Install Pricing Drop

Between 2012 and 2013, global investment in climate change mitigation and adaptation dropped $28 billion. When scientists say we need a dramatic surge in zero-carbon energy sources, the drop seems like bad news. It's certainly not good by climate action standards. But it's not as bad as it sounds either.[read more]

Sub-National Climate Change Actions Prevail Over National Politics

November 25, 2014 by Devashree Saha

In the US, national politics has not been friendly to the climate debate and partisan gridlock and dysfunction have routinely affected any serious response to climate change. With national action remaining tepid, it has fallen to sub-national actors to embrace and enact meaningful climate change policies.[read more]
