The newest affordable clean energy source that scientists have laid eyes on is the one provided by hydrokinetic systems such as ocean waves and free-flowing rivers. Researchers estimate that this ÃƒÂ¢€Ã…â€œfreshÃƒÂ¢€ source of energy could supply electricity to meet up to 10% of America’s power needs.
We all need electricity for powering different stuff in our home, to make our lives more pleasant. But if the electricity is produced using green sources it’s even better. One of the most used types of energy up to now was hydropower, but this one involves the construction of dams, weirs or other structures that could affect fish.
