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]

Radio Waves and Energy

I have found over the years that the vast majority of biomass to energy projects aren’t economically viable for one reason or another. I have looked at companies that utilize many different conversion technologies, and most of the time my job consisted of searching for fatal flaws of different approaches.[read more]

Green Energy Risks

Some citizens who are concerned about the long-term viability of the electric grid will no doubt want to purchase their own solar systems with inverters and back-up batteries. I won't discourage those who want to do this–the systems may prove to be of assistance. But I see no reason to subsidize these purchases.[read more]
