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, as well as phase out warming-inducing refrigerants.

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.

Age here isn't the issue; it's that we the US government is designed to spread power across multiple people and parts of government, and having a President who is willing to do the right thing isn't enough.
