Water Power Generates Sustainable Electricity

People have been using the power of moving waters for a very long time. Rivers have provided the motive force for milling for several centuries. The relatively recent commercial use of tidal power harnesses power from The Moon.

Hydroelectric Installations And Sustainable Electricity

Most people know water power best by the massive hydroelectric dams, such as Hoover Dam. Such projects are made with a massive input of human and petroleum energy. Concrete is a highly energetic substance that’s used in just about every type of modern construction. In fact, 8% of carbon dioxide emissions are in the form of concrete production.

Sustainable Electricity From Tidal Generators

Many coastal power companies are now investing in large wave machines. The “water snakes” that are being installed in Portugal should require very little maintenance over time, since there are only a few moving parts. Such devices also have the advantage of always being “on.” If sea levels rise, they rise with them. There are many different designs for wave power generation, since the technique is so new. Some designs have large paddles that are moved with the waves. Some are buoys that move up and down in the waves.

Most tidal generators are shrouded turbines that are placed in a river where tides come in an out between restricted inlets. While this restricts the number of places such facilities can be installed, the amount of power that can be generated is enormous – several times more than if those same turbines were moved by less dense air.

Micro-River Power For Sustainable Electricity

For those living near rivers or even seasonal creeks, small-scale distributed power generation can be realized in the form of micro water turbines. These contained units deliver a current, most often stored in a battery. They can he hooked up to the power grid, but you’ll need to put them somewhere near an inverter, and most people don’t keep those near rivers.
