Future Environmental Solutions
Alternative to the next level
Bio-fuels is still a relatively new energy that if further experimented with we could find a cleaner burning fuel and hopefully make us no longer dependent on oil. The other bonus of bio-fuel is that it is basically burning organic matter which the Earth has plenty of. Hydro electric power could also be further developed. A very small amount of water is dammed if humans went to the full extent energy crises would be a thing of the past. Lastly if nuclear fusion could be discovered humans would never run out of energy because all it takes is two elements and tap into the energy that is released when they are combined. This process is similar to how the sun burns the biggest bonus is that you never run out of things to fuse together therefore being a limitless energy source.
