HYDROPOWER

• Hydropower has been used for thousands of years
  beginning with water wheels used in mills
• Modern large hydropower plants are very expensive
  to build however they have lower operation costs
  than thermal or nuclear plants.
• A problem with widespread use of hydropower is
  that it is not distributed equally around the
  world.

Types of plants

• There are different types of hydro plants
• diversion hydropower plant
• Dams produce a large amount of power with out
  endangering the enviroment

Impact on society

• Hydropower has change the environment reduction
  in both the amount of fish in a river increase in
  sediment , decrease water quality.
• The water quality decrease because of the decayed
  material in the flooded areas, and human heath
  problems such as malaria.

5
Geothermal Energy

• This form of energy is not strictly renewable or
  eternal because earths rocks will eventually
  cool.
• The Italians have been running a power station
  fueled by hydrothermal power in other words steam
  plus hot water.
• The planets relatively small number of high
  quality reserves of subsurface steam and hot
  water limits the potential of this form of
  energy.

6
Geothermal Energy

• There is a great deal of heat trapped inside of
  earths surface waiting to be vented, but larger
  scale uses of geothermal power are still at least
  a decade or more away.
• Taking full advantage of this resource will need
  new technologies to tap into the lower ground
  levels of the geothermal reservoirs and make use
  of lower temperature geothermal.
