Is ‘going back in the Middle Ages’ too polemical? After all, there was no electricity in the Middle moluedecke@t- Ages, whereas wind turbines are built using the most modern technologies.
However, the natural rule of human technical progress is to always increase the available power and energy density. This historical progression began with draft animals in agriculture, moved on to medieval windmills and water wheels, advanced with the steam engine and combustion engines, and culminated in modern coal and nuclear power plants.
