The earth like our bodies needs to be taken care of. If we keep destroying and polluting it we won't have clean water, clean air or a healthy place to live.
Answer: Geothermal eergy has many advantages in that it is clean and reliable over the long therm. It is however not accesable in all areas of the Earth. It is limited to areas with active vulcanism in the geologically recent past or with specific geological formations. In North America this would be primarily limited to the Rocky Mountains
Solar Energy and wind energy are the energy of the future.
Solar energy can help grow plants which can be used as future energy.
Energy Future Holdings was created in 1882.
Zayed Future Energy Prize was created in 2008.
European Future Energy Forum was created in 2009.
Abu Dhabi Future Energy Company was created in 2006.
Geothermal energy might be a good energy sources and it might be commonly used in the future because there are clearly no disadvantages to geothermal energy.
Solar energy !
In the future the uses remain the same: production of electrical and thermal energy and nuclear weapons.
Wind energy is ONE energy of the future. But due to its random accessibility (sometimes it's not blowing) we'd need other energy sources as well to fill the gaps.

I consider that the nuclear energy is a chance for the future.
