Almost all aircraft carriers are nuclear. Same with submarines. A lot of other surface ships also. Nuclear is considered green.
Problem is planes and tanks, as well as trucks, etc.
They are studying a way to use excess power from the nuclear reactors on aircraft carriers to manufacture synthetic jet fuel from air and water. It takes a lot of electricity, but it can be done. Sabatier process is where it starts.
Tanks and trucks. Well they would have to tow a lot of solar panels or windmills to keep them powered.
We have plenty of lithium in the US, but it would have to be strip mined. Enough in California to make every car electric. Cobalt (for more efficient batteries) is what is hard to get and China owns about 90% of the cobalt mining in the world, which includes South America, Africa, and Asia. Tesla is using iron in lithium-iron batteries for half their cars now due to obtaining cobalt. Cobalt-lithium batteries are used in their high mileage cars.
Like I have been saying. For us to go electric vehicles, we have to get the mileage up, the price of the vehicles down, and the charging times down. Then the electric grid needs more nukes, windmills, and solar panels, as well as some type of cheap battery storage. The grid should go alternative energy before the vehicles due to the need to charge the vehicles.
