Energy resources

Classification: Conventional & non-conventional

Conventional resources: Coal & lignite, petroleum & natural gas, water, nuclear fuel

Non-conventional resources: Solar, wind, tidal, geothermal

Thermal power plants

  1. Study the Carnot cycle with related pressure -volume and temperature -entropy diagrams. Define efficiency under ideal conditions

Hydropower plants

Nuclear power plants

Internet site: Wind Mills

If you think windmills can only be found in the Netherlands, think

again. Windmill expert Mark Berry takes visitors on a tour of windmills

throughout the world. The site covers everything from historic mills to

modern wind turbines to where to buy your very own.
