Water

• Water is very common on the Earth. It is mostly
  found in saltwater oceans which cover 70,8 of
  the Earths surface , but also in rivers,lakes
  and in a solid state, in glaciers. Some of the
  Earths water can be found below the ground or in
  the atmosphere ( clouds, water vapour )
• Thanks to water or rather its energy , people can
  generate electricity.

Water energy

• Hydropower is used for industrial purposes.
  Nowadays, water energy is usually converted into
  electricity.

• Hydropower can be much more cheaper than burning
  fossil fuels or nuclear energy.Areas with
  abundant hydroelectric power attract industry
  with low prices of electricity.
• In some countries ecological reasons have an
  influence on using water energy ( environmental
  protection care ), they are becoming more
  important than prices.

Advantages of using hydropower

• Hydropower is much more cheaper than burning
  fossil fuels or nuclear power,
• Thanks to water energy the natural envirnoment is
  not polluted,
• There is much cheaper electricity in the areas
  where, hydropower is used than in other areas,
• Turbines that produce water power dont make too
  much noise,
• Hydropower can be used for tourist purposes as
  well as for therapeutic and medical reasons.

Disadvantages of using hydropower

• It does change the envirnoment by affecting
  natural habbitats in rivers,
• It may happen that hydroelectric power stations
  deteriorate water quality and its flow,
• In the event of drought , power stations wont be
  able to produce electricity,
• Many times using hydropower disrupts fish
  spawning down or upstream,
• It destroys the wharf envirnoment,
