I'm suggesting that what we do to replace the kinds of carbon-producing energy we have is to use renewables, but the cheapest source of new energy is when we cut back our use. For example, in the house I'm living in, we installed a geothermal unit in 2009, and it paid for itself within 10 years. Now the cost of electricity in this house—it's run on an electric current, that geothermal unit—is amazing. It's quite amazing. I thoroughly recommend it to everyone. It's a good investment.
