Unfortunately technology requires lot of energy
For the past century we have been getting this power from fossil fuels which is a limited resources , expert can’t guarantee that they will discover enough fossil fuels to keep us going for the next 40 0r 200 years.
Even if we had unlimited supply of fossil fuels using solar energy and other renewable is better for our environment.

They’ve been here since the world begun
These fuels are turned into usable forms of energy: electricity, heat, mechanical power and chemicals
