Watching Barack Obama, Bill Gates and others speaking on climate

Cape May - Watching Barack Obama, Bill Gates and others speaking on climate change this morning on the Weather Channel and how "we" need to change our lifestyles, conserve energy and use less fossil fuels. Interesting comments coming from men that own several mansions, private planes and high end cars. Just wondering how they and others like them, heat and cool these mega mansions, fuel their planes and cars?
