Ok, let me add. Wind, Photo-voltaic and Hydro are non stable sources. They depend on climate conditions.
You can only ensure national energy with Nuclear and Fossil energies;
if a climate blackout will happen.
That's why there must be a technology to store the energy instead of using it for the moment..
Some times wind energy just stays still because there is no need of energy in worst case you will have 10 structures and only one is active..
If you would store the energy in hydrogen then you could generate energy as needed -ok you have a lost of some serious amounts of energy to create hydrogen but the benefits are high and you can operate all alternative energy systems at max..
Second idea is not to get electricity directly but to store the pressure like in a balloon.. if needed let the air out and let it drive a generator to get electricity when needed..
So I don't understand why we and other sun rich countries don't invest in such technology
To build a palace or to buy some prestige object they spend money and no one ask where it comes from but for something useful we don't have the money.. 40 Mrd dollars in such projects would be a good start for our future..
Fossil energies will be extremely expensive in the future and it makes us depended on foreign forces, it is not reliable in future or war (sanctions )..
Nuclear energy is needed we need at least 5 nuclear power plants but it's risky, extreeeeeeeem dirty where to go with radioactive junk? And in war time it's also easy to cut down our energy..
Decentralized energy is better if you generate energy everywhere every province, every city, every household then it's harder to cut down your energy
