The clean energy movement has an unfortunate history of sacrificing the “good” in search of the “perfect” solution. Here’s an example: Kevin Costner (yes, the actor) reacted to the Exxon Valdez oil spill by investing over $24 million in a company that makes high speed centrifuge machines that can separate oil from water at the source of an oil spill. So, rather than having to skim the oil off the water or collect and transport massive mixtures of oil and water, the machines sends clean water back into the ocean on site and collect oil on the tanker. That way, the oil never reaches land, which greatly reduces the impact on wetlands, birds and sea life.
Sounds great, right? Not so fast.
