Harvesting frozen methane (Japan's already started experimenting) from seabed is also potentially good.
SMR's are small nuclear reactors designed with modular components. Aka, like a trailer sized replaceable power plant.

Instead of making each a unique design (huge cost of large reactors), create the model t , test it, then produce it in large numbers.
combined with natural gas, you'll watch coal use shrink, along with carbon emissions.
