It makes solving climate change seem deceptively easy. In fact, though wind and solar can generate all a country’s electricity on some days, renewables still account for less than 8% of the world’s total power output.

Moreover, cleaning up electricity is only part of the battle. Even though gas-fired heating and cooking can be at least as big a source of greenhouse-gas emissions, renewable heating gets minuscule attention.
