Solar and wind are what we urgently need.
America needs projects and goods budgeted based on emissions impact. The American corporations (and the public) should be put on CO2 budgets for nonessentials, so we have more CO2 space left over to construct renewables as fast as we can.
We are 6 years out from cascading tipping points. The hotter it gets, the faster we get to "in your lifetime" effects. The climate is already screwed. How much worse it gets is up to us.
Solar and wind have horrible energy efficiency. Crude is oil is insanely efficient in regards to how much energy it takes to get how much energy it provides. Coal is like a 1 to 30. Really good. Wind is like a 1 to 7. Really bad.
Bottom line tho, there is a direct correlation between personal freedoms and energy efficiency. The more efficient an energy is the more freedoms individuals have. This is why we are seeing REGRESSION in energy forms.
For a long time in human history it took human energy to do things. Ie rowing a boat. It took a large number of slaves to row a bigger boat. That means there will fundamentally be fewer free people and more slaves/serfdom types.
Then we have the invention of sails. You could harness the wind energy. Which was more efficient than human energy and thus less people required to power the boat. More individual freedoms in society.
Look at modern times a single guy can operate a big boat with a Diesel engine. Requires 0 slaves/serfdom type people.
But now we are regressing, by design, back to wind energy.
Once everyone switches to electric cars they will say power grid not strong enough. No personal vehicles. Use government bus routes.
