Professor Richard Alley explains why switching to clean energy — that which does not output CO2 — is pretty much an infrastructure problem, one which we’ve already solved once.
The technology we have to produce energy that does not rely on the burning of fossil fuels already exist, though they’re expensive. The main problems are those of cost-effectiveness and how much time we actually have before the issues become too great to overcome, and whether we’ll spend the necessary money to change our infrastructure before the damage we’re bringing on ourselves will cost way, way more than the cost for making the jump.
So the real question is not whether to do it, it’s a question of when. When will we stop putting short term profits over long term viability? When will we buckle down and solve the infrastructure problem that’s destroying our planet’s climate, in a way that will cost many more lives than did the emptying of chamber pots onto the streets?
