The global rebound effect
Energy efficiency improvements help us use less energy, and that saves money, which encourages us to use more energy. That's the standard rebound effect. No, it doesn't stop efficiency from saving energy, but it can significantly reduce the savings. But this site is about global energy, and the global rebound effect is likely more important than the standard one, and also quite fascinating.
Produce ethanol, and that means we import less oil. Where does that oil go? Do they stop pumping it because we don't use it? Or do they pump it and sell it to China instead? The answer is crucial for evaluating biofuels, and it is closely related to what happens when we drill more wells offshore and pump more oil. So what does this mean for California's new low-carbon fuel standard? Find out.
