Hydro power
1.Water wheel (from the past) 2.Water/tidal turbine (modern)
Hydro power is the most stable renewable energy source. Hydro comes from moving water Hydro power is a renewable energy so hydro power doesn't pollute the air. Hydro power could create energy but needs an invention to help.
What is hydro power
Tidal and water turbine
Modern invention  Tidal turbine are underwater  Water turbine are used to support dams
Inside the turbine
Water wheel
Water wheel are inventions from the past Water wheel is a machine for converting the energy of flowing water into useful form of power Before electricity, in the olden days they use water wheels. Water wheels is made out of large wooden or metal wheel. With bucket outside driving the surface

Time line of hydro (past)
Water wheels are used in the ancient world Water wheels are continue to be used Yellow stone, USA become a national park OTEC is first suggest by French scientist The first hydro plant begin operating in Appleton,Wisconsin Hydro electric power station are built in Germany and at Niagara fall, USA Electricity is produced by geothermal energy The world first geothermal plant open in California,USA The world first OTEC plant is built in Cuba The Hoover dam is completed in united states
Time line of hydro (present)
1959 1960-1967 1966 1981 1984 1990 2000 2003 2007 The kariba dam is completed in Africa France build a tidal energy station The first geothermal power plant is in Japan OTEC research begins at Hawaii natural energy laboratory Itaipu Dam built on the boarder Micro hydro project begin operating around the world Islay were station open in Scotland The wold first salt power is open in Norway The three Georges dam in China become the largest dam in the world
Inside the modern waterwheels
Positive and negative
  Positive Doesn't pollute the air Clean Renewable energy
Negative
 
Takes up lots of space It might cause natural disaster Its renewable energy but its too slow.
