A clean-energy cookstove is one of the most innovative and important recent inventions; it will change our world. Three years ago, I joined the Global Alliance for Clean Cookstoves as the culinary ambassador. Our goal is simple: By 2020 the goal is to have replaced inefficient cooking technologies with clean-energy cookstoves in 100 million households. We have so many great supporters that really believe in this important mission. The most important thing is that we show the real value of using clean energy not only in terms of money, but in terms of demonstrating the potential to feed many people at a low energy cost with zero emissions.
