Why conserve energy? Because there are problems with every known source of energy.
Fossil fuels pollute and are in limited supply. Nuclear fission creates dangerous byproducts. Nuclear fusion still isn’t practical. Solar collectors take up a lot of space, wind farms aren’t very attractive, and building hydroelectric dams usually pushes people and animals out of their environments. So, it looks like energy conservation is the wise way to go. Here are some ways to use less energy.
