If all households took personal responsibility in generating domestic use energy via wind and solar panels, we would not need nuclear power.
Bulk electricity supplies can be met by tidal, wind and solar generation.
Hydro-electric supplies via mega dams are an environmental disaster, and always have been.
Hydrogen as a fuel is also coming on stream.
NASA considers that liquid hydrogen and liquid oxygen is the most cost effective fuel for moving payloads into space one past the initial phase of the launch, powered by kerosene.
Contrary to some thinkers, hydrogen is a fuel, not a "carrier".
It can be easily generated via hydrolysis of water, producing both hydrogen and oxygen in the exact proportion for combustion to form water.
A totally renewable and clean, carbon free energy source for internal combustion motors, cooking and heating as well as for industrial use.
