Going green has become a global event. Billions of dollars are spent every year to improve our environment, better businesses, and to improve customer service. In 2010, the amount of global investments in alternative energy projects will increase from $130 billion to nearly $200 billion! Too bad it isn’t cheaper to be eco-friendly!  Even so, multiple projects are being funded and new technologies are being introduced on a day to day basis. These technologies include clean coal, wind turbines, solar, and hydroelectric, just to name a few.

One technology mentioned recently is the marine energy approach. The marine approach uses energy of shifting tides, underwater currents, or shoreline and offshore waves. What can this do for you? Well, what is great about this method is that unlike many others, is an infinitely renewable resource. Also, tidal energy is very regular and can be utilized on a large or small scale. These positive things help move our world closer to a healthier environment.

However, the marine energy approach has its cons too. Unfortunately the best way to capture this energy has not been agreed upon yet, and even if it was, we probably won’t see it in effect before 2030. The marine approach could also disrupt natural water flow, ecosystems, and tides. It would have to be carefully regulated to be sure no more harm is being done than good. Lastly, costs may range from 15 to 30 cents/KWh, which is double or triple the cost of coal.

As technology advances, it will be more common to see businesses and households take hold of these energy saving approaches. Worldwide efforts are being made to better customer service, business, and most importantly, the environment.
