Indeed some conclude that photovoltaics are near a threshold where they will have a cost advantage over CST and soon even over fossil fuel generation.

It was started as a project to educate and inspire entrepreneurs, investors, and policy makers to think big about solving the climate crisis.  It was an effort to answer Sunil’s question, “What does it take to make a difference with clean energy technology?” (more…)
