>That said i dont see how we will get off fuel completely

One solution is better batteries with more capacity, faster charging, cheaper and longer life. All of this has been achieved in labs. It will take time to build factories and mass produce this.
Another solution is to use electrolysis to produce hydrogen from excess wind or solar power. This can be use in fuel cells to power cars and ships and trains and maybe even planes. This technology is ready, but this needs even cheaper green energy and more efficient electrolysis or a higher oil price to be competitive.

You can use bio-gas made from human or animal waste. You can also use excess energy from wind and solar to produce gas.

in Europe they even use excess wind and solar energy to produce hydrogen and methane

as soon as you get enough excess renewable energy in a region and enough storage it can run almost continuously
