There you go. That's your answer right there. That's why efficiency is so important and your envelope is important, because you cannot possibly—I mean, it depends on how deep your pockets are—expect the same service immediately from renewable energy that you get from fossil fuels. It's a different type of energy.
Now, when we look at cities, we want to electrify everything. We want to electrify our buildings. We want to electrify transportation. That speaks directly to energy supply. When that energy needs to be used by everybody—because everybody's going to come home and turn on the lights and the heat, and plug in their electric vehicle—that's peak demand. That's what you have to manage. You have to really look at efficiency as way to, first, reduce the demand, and then you have to look at your best sources of renewable energy to reduce the carbon footprint.
