Today in Cleantech

Compared to wind and solar, geothermal has glided under the radar. However, this week’s news of Vulcan Power’s $100 million-plus round of financing is putting it in the spotlight. Earth2Tech had a Q&A with the firm’s CEO, Robert Warburton, in which he reveals that financing, not technology, is the main hurdle for geothermal projects. It’s not to say that technology doesn’t play a role, only that it’s marked by gradual improvements rather than “game-changing” leaps. Looks like some investors see opportunity in Vulcan Power’s orderly pace, particularly as renewables encroach on the grid.
