Alternative energies are very limited.
Solar energies only work with Sun, at night there is no Sun and Sun is not always available all the time or in all the places. Sun can be too weak or the sky can be obscurred by clouds. Some days ago there was a big full moon, but I was unable to see it, I was unable to see before it reached its maximun and still today I am unable to see becuase the sky is covered by clouds. Some years ago Mars was also big, but for three months I was unable to see it because the sky was cloudy for three month and I live in Brasil, the tropical country full of beaches and Sun.
The Sahara desert is an excellent place for solar energy, a lot of Sun, no clouds, no rain, but there is nothing there and nobody lives there, also there are sand storms, much better, sand hurricans, imagine the sand of a snad hurricane polishing the solar panels.
Wind energy also can be useful, but to work it need to be wind and wind not always is present and depend on seasons or the hour of the day. If there is wind you have energy, if not you have wait until the wind comes again. Wind mills work in this way.
Sea tide energy can be useful, but only work in places that have big tides and also depend on the hour of the day.
The only sources that can deliver constant electric energy that you can use at any moment you want or need are coal, oil, gas, dams and nuclear energy.
Stupidity also evolves!
