About “renewable energy”
Compared to electricity from thermal and nuclear power plants, electricity from solar and wind power plants was awfully expensive, so it was economically justified to build them only in relatively isolated places for local power supply since it was expensive to pull wires from the power grid there. Yes, and energy is lost in fair quantities when delivered by wire, and therefore even “expensive” solar energy turned out to be more profitable than seemingly cheap thermal and nuclear energy.
Thirty or forty years have passed since thirty or forty years ago. However, the arguments of the aforementioned reasonable people, apparently, turned out to be so strong that many repeat them to this day, being in full confidence that if once, for example, computers were so expensive that only very cool research institutes of especially cool people could afford them. countries, it will always be so, and therefore personal computers in mass use simply cannot be.
So, over these thirty or forty years, solar electricity has fallen in price by about 50 times, and when compared with 1977, by 250 times (from $76 to $0.3 per watt).
Here, of course, inflation should also be taken into account, but even without taking it into account, the scale is impressive.
For wind energy, the ratio is less impressive (primarily because it was initially less…
