On the other hand, I kept thinking about what I had witnessed in my travels. India, for example, has a population of 1.4 billion people, many of them among the poorest in the world. I didn’t think it was fair for anyone to tell Indians that their children couldn’t have lights to study by, or that thousands of Indians should die in heat waves because installing air conditioners is bad for the environment. The only solution I could imagine was to make clean energy so cheap that every country would choose it over fossil fuels.
