The drumbeat for a fossil-fuel-free energy utopia continues. But few have pondered how we will supposedly generate 25 billion megawatts of total current global electricity demand using just renewable energy: wind turbines, for instance.

That’s more than twice the size of North America, all the way through Central America.
