We could have displaced them almost entirely in the 60s and 70s with nuclear, and we can do so today with renewables and nuclear. We haven't yet because it turns out oil and gas are pretty profitable, and climate change became a recognized issue just as the US was moving toward a more laissez-faire style of governance.

We can't currently displace oil usage for certain fuels, but we can start creating it from renewable sources using the carbon-free energy sources to power the process. Basically convert nuclear energy (via uranium or the Sun) into chemical energy.
