Our thirst for oil and other fossil fuels has brought us to the point where we are doing irreversible harm to our planet. We are also quickly realizing that we are running out of these non renewable resources. As the global economy continues to grow, a world fueled by green power is not far off.

Once thought of as silly hobbies by eco-maniacs, green power has been embraced the world over as the future of energy. From wind turbines that generate electricity to bio fuels and electric cars, our entire way of life and how we power it will soon change forever.

Green power has been around for a very long time, in fact windmills alone go far back in history. Only until recently have these innovative sources of power been taken seriously. Now, as more money is being invested into research, green power sources are being developed that will eventually contribute to how we fuel our need for energy.

Wind farms have proven to be the most efficient new alternative source of energy. Wind turbines produce an enormous amount of electricity while giving off nearly zero harmful emissions. At this point, only around three percent of the world’s power needs are met by wind turbines. However, that number is exponentially rising every year, and they will be a mainstay in our power supply in the very near future.

As long as there is wind, they can generate a lot of electricity. They are relatively inexpensive to build and require very little maintenance once in operation. Wind turbines have very low emissions and they can provide a steady source of clean energy for a long period of time.

Turbines have also been adapted to work underwater as well. Capturing energy from moving currents, waves and tides, engineers have been able to design turbines to generate electricity without producing any emissions in the process. Unfortunately, the water turbines need a lot of maintenance, and wind generates more energy than current technology allows water to.

Solar power is getting popular again, and on large scale projects as well. The western United States has quite of large solar farms which are making electricity every time the sun shines. Solar power has tremendous potential as a renewable energy source, however they are not cheap to build and maintain. Until these costs go down, it is not practical to use it as a source for our power needs.

Coal and natural gas are big sources of power for us, but unfortunately both of them are limited resources. Natural gas is a clean burning and highly efficient source of energy, and fortunately natural gas has a cousin that can help feed our need for power. Methane gas burns like natural gas, and is also a clean source of energy. There are abundant supplies all over the world, from undersea deposits to gas from landfills. The technology to harvest methane for wide use is still being developed, but the future looks good.

There are limitless supplies of renewable energy sources available to feed our hunger for power. The greatest promise that green power has is that it can come from different sources and be integrated to work together. As more time and money are spent on developing these promising technologies, the more our society will adapt to a green way of life.
