As fossil fuel reserves are beginning to dry up we must look to other sources for our energy needs to support our lifestyles. The planet still has many fossil fuel reserves, but they won’t last forever.

Clean energy sources such as wind, solar and hydroelectric are becoming more and more popular and as their technology is improved they are also becoming cheaper and cheaper. The ultimate goal is to make them cheaper than fossil fuels so that we can wean ourselves off of fossil fuels.

Other types of renewable energy are also being developed, and many of them seem very promising. One of these energies is wave energy, which is garnering much excitement for powering cities in coastal regions.

The energy in waves is very dense, so energy can be taken out of them with a relatively small power plant. Wave energy also doesn’t break like sun energy or wind energy may.

A country famous for its beaches and surfing, Australia, already has many of these wind generators powering its cities.

One off the coast of a city just south of Sydney is about 100 yards off the beach. It weighs about 500 tons but it can power about 500 homes and desalinate 2000 litres of sea water every day, about enough to supply those same homes.

It is very well built so that it can survive most major storms. It makes about 500kW of energy and it was $4.7M to build.

Though it is still on the expensive side, as technology develops many believe that it has the best chance of any of the renewable energies out there to become much cheaper than fossil fuels.
