tl;dw Most of the energy from fossil fuels is wasted. Energy from renewable sources is much more efficient. In the future, we won‘t need the same amount of energy that we need today.
In other words, if we consume an X amount of fossil fuel energy today, and we want to get rid of fossil fuels, we won’t need the same X amount of renewable energy to do that, but only a fraction of X.
