A wind turbine must have a clear shot at the wind to perform efficiently. Turbulence, which both reduces performance and “works” the turbine harder than smooth air, is highest close to the ground and diminishes with height. Also, wind speed increases with height above the ground. As a general rule of thumb, you should install [...]

A windmill takes energy from the wind (fluid) and produces power. The maximum theoretical power is 16/27 of the wind’s power this is known as the “Betz limit”. The wind’s energy, because it is moving, is in the form of kinetic energy and if all the energy was captured by the propeller or rotor there would not be an airflow consequently it can be said that the “lost” energy is used to keep the air flowing.

The wind has been used to power machines capable of grinding corn, pumping water and producing electricity for hundreds years. There are records of Persian and Japanese wind machines as long ago as 200 BC. Wind power probably has its origin in the ancient civilisations of China, Tibet, India, Afghanistan, and Persia.

In principle, a fuel cell operates like a battery. Unlike a battery, a fuel cell does not run down or require recharging. It will produce energy in the form of electricity and heat as long as fuel is supplied.
A fuel cell consists of two electrodes sandwiched around an electrolyte. Oxygen passes over one electrode and [...]

A micro hydro plant is below 100kW. Improvements in small turbine and generator technology mean that micro hydro schemes are an attractive means of producing electricity. Useful power may be produced from even a small stream. The likely range is from a few hundred watts (possibly for use with batteries) for domestic schemes, to a [...]

With a little effort we can reduce our energy use at home. Energy efficient light bulbs, a degree lower on the heating, switching off the odd stand-by appliance will all help. But will this save energy? Why not I hear you cry! Well what will you do with the money you save? A drive to [...]
