Future energy where will we get our energy?
we are going to have a big energy problem in the future. TOday, the world uses 320 billion kilowatt-hours of energy a day. By 2100, we will use three times as much energy. How will we get the energy? Today, we get a lot of energy from fossil fuels: coal, oil, and natural gas. But fossil fuels are dirty, and they will not last forever. In the long term, we will have to find alternatives. We will need renewable energy.
