Using a desalination process to remove the salt from the ocean waters can create a fresh water paradise. While it has been in use in the Middle East and other areas of the world for quite some time, it is expensive and uses a lot of energy in the process.
The hydrogen fuel cell has been proclaimed as one of the best technologies, mainly because it is a pollution-free alternative. It combines hydrogen and oxygen, creates energy and the byproduct is water.
Solar cells and solar collectors are coming of age. Lowered prices combined with more efficient (and smaller) units are giving businesses and residents some incredible options.
Tidal and wave movement: Harnessing the movement of the waves and converting into energy is another technology that is showing a lot of promise. They are still working out some of the kinks, but taking a natural process and converting it into energy is a no-brainer.
Roof gardens: The world’s cities are beginning to look a lot different. Using the rooftops as gardens not only brings an additional food source, but the plants act as a natural source to clean the air as well as reduce air conditioning use.
