Solar panels folks. Solar panels. Wind. Batteries. We can do it, no problem. Electricity costs a little more, but your car ends up costing less. Less maintenance on fewer parts - just swap out the battery which declines in cost each year.
Keep fossil fuels and wood for the things solar & wind will have trouble covering: airplanes, ocean shipping, winter heating.
You only need the first 15 minutes of this talk to see why current renewables won't scale. The world needs something like 15 terawatts. When this talk was recorded, solar electricity produced something like .001 TW. We're now closing in on .03 --- and there are huge parts of the world that still haven't industrialized yet. We'd apparently need to be printing and distributing and deploying solar cells the way we do newspapers to have any hope of using photovoltaic to offset our total energy demand.
Nuclear doesn't scale either, but the notion that we're all just holding back on renewables out of greed because all it takes is wind and solar... well, it's easily refuted.
Fortunately we don't have to cover all shortfall with just PV. Increasing energy efficiency and reducing consumption (including personal car ownership) in the first world can get us there the rest of the way.
Our descendants have to do it. Coal, oil, and natural gas have maybe a century left. Fracking made more hydrocarbons accessible, but the supply is still quite finite.
We can't do the thing suggested upthread, eliminating dependence on all consumable energy sources by harnessing current wind and solar technology. Ultimately I agree that we have to find a way to do it. But there's a virulent belief that we can do it with technology that is being produced today, or might be produced in the near future if demand changed. No.
