People have used wind power for more than 5500 years but for electricity it was used in 1888.

How does it work?
It works like this: the wind turbines turn the generator which produces the electricity.

  • Hot water is pumped from deep underground through a well under high pressure.
  • When the water reaches the surface, the pressure is dropped, which causes the water to turn into steam.
  • The steam spins a turbine, which is connected to a generator that produces electricity.
  • The steam cools off in a cooling tower and condenses back to water.
  • The cooled water is pumped back into the Earth to begin the process again.

    High-pressure tanks weigh much more than the hydrogen so a full tank contains only 5.7% hydrogen. Hydrogen fuel is hazardous and it also tends to leak easily from tanks.

    Hydrogen is an energy carrier that can be used to store, move, and deliver energy produced from other sources. It is used in cars, in houses, for portable power, and in many more applications. ]]>     2021-05-13 14:50:32 UTC https://padlet.com/anitajokic22/316gnlqkqnt80ixb/wish/1521277757     Field of solar panels anitajokic22 https://padlet.com/anitajokic22/316gnlqkqnt80ixb/wish/1522391016 2021-05-13 19:06:22 UTC https://padlet.com/anitajokic22/316gnlqkqnt80ixb/wish/1522391016
