ENERGY FACTS

Electric energyEverything we have and do requires energy, from eating food and the foods we eat, to working and our workplaces, to driving and the cars we drive.

Further, human beings consume more energy now than ever in human history because we have more people, more stuff (more toys, technology, clothes, cars, etc.), and we depend much less on our muscles and much more on machines to get things done. Thus, humans now more than ever depend on lots of cheap energy, and without abundant cheap energy, we can’t have and do all we want.
