There are many types of energy available for human use, but man tends to overuse some of them which leads to environmental problems.
- Fossil Fuels: by far the most exploited energy resource but not for much longer. (Coal, Oil, Natural gas)
- Nuclear Energy: highly productive, but comes with hazardous issues.
- Hydroelectric Energy: harnesses the kinetic energy of flowing water. Sounds great but what happens to the river? And what if there is no river nearby?
- Solar energy: just like plants have been doing for millions of years! Renewable because the sun will be around for a few billion years more! But if solar energy is so great, why are we not all using it?
- Wind: Works great! As long as there is wind. Kind of noisy though.
- Geothermal: harnessing the thermal energy beneath the Earth’s crust! Nees to find an opening though.
- Tidal: using the moon’s gravitational energy that the oceans convert to kinetic energy.
- Hydrogen Fuel Cells
