Hydropower has been a slumbering giant in the energy game. Since the 1960s, its use has actually gone down compared to other energy sources. This is beginning to change.

As an investor, how can I help sustain the earth? I call it sustainable investing. It is simply investing in companies whose products or services promote the sustainability of the planet. Companies providing technology for renewable energy is a perfect example. In particular, I will talk about solar companies in this post.

Although that is a possible threat, we still couldn’t ignore the fact that hydropower energy is indeed one of the best alternative sources of energy that we have.

The next frontier is Water Turbines.These are similar to wind turbines and are placed in the water currents. The current spins the turbine to produce electricity. This technology dates back to the Romans. Nova Scotia has a turbine producing 20 MW since 1984. La Rance barrage in Normandy puts out 240 MW and was installed in 1966. In 2007 New York City tried installing turbines in the Hudson river. The current was so strong it was snapping the 20 foot blades. In 2010 using what they have learned a new project is under way to install 30 underwater turbines in the East river between Queens and Roosevelt Island. The completion will be sometime in 2011 if all goes according to schedule.

When you are starting a business you are out hunting for the next piece of income. At the same time you are out hunting, set up a farm of sustainable ongoing repeat business you’ll be much more energy company for the long term.

This grant scheme is a good start, but will not cover the homeowner, on a small budget, who wants to do only part of the things needed at a time. A plan still needed, is one that is very attractive to all homeowners and is simple and easy to use. It should have grants for smaller projects, since any change for the better helps the environment.

So now that you know this information that we gave you some hydropower energy facts, we assume that you have a vivid picture on hydroelectric energy source. We hope that we have given you something that you could use for a long time. And please always remember: help save the environment in any way that you possibly can.
