How do you think humans will generate energy in the world?

Answer 1

Aciani1's opinion:

In the distant future, human energy needs will be met with a combination of technologies. Bio-based fuels will be used where a high energy density power source is required, such as in cars, trucks, airplanes, military vehicles, and remote power applications.

For mains electrical power, we will use a multi-tiered system consisting of multiple technologies. Houses will receive most of their electrical energy from individual solar and wind power devices, buffered by battery banks. There will be large scale solar, wind, hydroelectric and geothermal power stations to provide the bulk of industrial energy needs. Medium sized energy storage facilities, and hydroelectric and nuclear load following stations will be used for peaking power and production fall-off at solar and wind facilities. Small bio-fuels powered peaking plants may be held in reserve for extreme demand conditions, or prolonged underproduction from solar and wind sources.

The use of electric vehicles will be unlikely, as the energy demands caused by these vehicles exceeds even current fossil fuels power generation, and peak charging times would coincide with minimum production times for solar and wind power.

Using the renewable energy resources, it is unlikely that even half of the current energy requirements could be realized. This is due to the coincidence of usage times to output times, rather than the rated output of the generating devices.
