Solar PV Internal Costs

This article will gather some data about TEC community views on the global average internalized cost of distributed solar PV energy. Please add your opinion so we can gather a statistically significant sample and get a meaningful indication of the consensus (or lack thereof).[read more]

It Was $40 Billion Cheaper to Install 32GW of Solar Globally in 2013 than in 2012

November 25, 2014 by Stephen Lacey

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]
