Hydroelectricity refers to the production of electricity through the use of falling or free flowing water. Hydro power systems convert the kinetic energy in the water in a turbine which drives a generator.

Hydroelectricity is the most widely used form of renewable energy accounting for 16% of global electricity generation. China is the largest hydroelectric producer thanks to the massive Three Gorges Dam with a capacity of 20,300 MW.

The other end of the Hydro scale is known as small hydro or micro hydro. These devices can be placed in a small river and provide enough electricity to power an average home.

Although the electricity produced by hydroelectric power plants do not produce carbon emissions they can still have a significant impact on the environment due to the large reservoirs required for their operation. Areas upstream from the dam will be subject to extensive flooding. Downstream marshes and wetlands can be destroyed by the reservoir.

  1. A fuel powered ctsbumoion generator is most cost efficient. You can get gasoline powered generators for under $150 per 1000W, which would do that. Solar and/or a small wind turbine would be next up. You would need a battery set to store the charge, and an inverter to power your AC loads. Your computer, TV, and radio could be set up to work off of battery directly, if you choose the right ones.Unless you are going to build a dam an all that, collecting energy from flowing water is not economical.In any case, get a propane stove and dry your clothes on a line. You should get a tri-fuel fridge, if not a 12/120V one.
