TIDAL ENERGY
Tidal Energy or Tidal Power is an example of a renewable energy where tidal action from
the ocean is converted into electric power. It could be generated in two way, tidal stream
generators or by barrage generations. Tidal power is similar to wind turbine, but it rotates
underwater and is driven by the movement of water. Although it is not widely used, tidal power
has potential for future electricity generation. Tide mills are used both in Europe and in the
Atlantic coast of the USA. Tidal power is the only form of energy which derives directly from
the relative motions of the Earth–Moon system, and lesser extent from the Earth–Sun system.
The tidal forces produced by the Moon and Sun, in combination with Earth’s rotation, are
responsible for the generation of the tides.
FOSSIL FUELS
Fossil fuels are an example of a non-renewable energy that was derived from organic
matter that is trapped within the layers of sediments in the Earth for years. It is highly
combustible making them ideal to be an energy source. They are typically retrieved through
drilling or mining. It is the world’s primary source of energy. An example are coal, oil, natural
gases.
