If it were fantasy our usage of solar, wind, hydroelectric and nuclear power would not be increasing each year.What you seem to be talking about is a fantasy.
You severely underestimate, the power of the sun, wind, water, and the atom. We continue to transition to non fossil fuel sources of energy.And no energy exists which feeds 8+ billion people on electrical currents from alternative energy sources.
Good reason not to waste them on transportation.Our agricultural methods collapse without fossil fuels.
Your reality is the fantasy and one not share by very many people.Global freight screeches to a halt. Many billions of people cannot be sustained in a world without abundant fossil fuels. Investing in a fantasy doesn't make the fantasy a reality.
