The world is quickly discovering that we have reached our limit with traditional power sources. The continual increase in the use of fossil fuels is doing irreparable harm to the environment and eco systems around the world. We are also peaking in our oil availability, and demand is continually rising. Green power options are the future of energy.

Green power has come a long way in the last couple of years. From just being a hobby for eco friendly geeks, these innovative and emission free emerging technologies may just save the world from ourselves.

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.

With more money being invested in research and development, these technologies are being refined and geared towards replacing our reliance on fossil fuels. The development of wind farms has proven to be the most cost effective way to produce green and renewable energy so far. Their ease of manufacturing and installation and low maintenance make it a popular alternative that is being developed. Right now, only three percent of global power needs are supplied by wind farms, but that number is expected to skyrocket in the next couple of years.

Wind farms produce almost no emissions, they are easy to maintain, and they generate tons of power without burning fossil fuels, such as coal or natural gas. They can be easily tied into existing electrical grids, and as long as there is wind, there will be power. The best part of wind power is that is very cheap to install and set up.

Turbines have also been developed to work under water. Oceans and rivers have tides or currents that are consistent and predictable. Developing underwater turbines have harnessed this power have been able to generate electricity. While being totally renewable and green, sea turbines need a lot of maintenance, and finding places to put them can also be a challenge.

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 both huge sources of energy, but they are in limited supply. An alternative to natural gas is methane, which is found in landfills as well as in pockets under the oceans all over the world. Clean burning and efficient, methane is showing great promise, but the technology is not available yet to harvest this resource.

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.
