What Biden has done is to cut the issuance of drilling leases to the minimum required by law, pass the Inflation Reduction Act, enact a regulation to force vehicle electrification, and similarly force fossil fuels out of most power plants.
What Biden has not done: stop issuing drilling permits or impose export restrictions on fossil fuels. The former has some serious limits because of how the courts treat the right to drill as a property right once you hold a drilling lease, and the latter is simply untested.
The issue is mostly availability and infrastructure. Wind and solar only produce energy when there’s wind and solar. However new renewable energy is cheaper to produce but is inconsistent and not as reliable as a coal burning plant.
You can do something like Australia did with their huge Tesla battery to store the renewables but that’s not very economically feasible for developing nations, but they should still be building out new renewables for energy and filling the gaps with fossil fuels instead of just sticking with fossil fuels entirely.
