Hydro electric power is made quite quickly, once the infrastructure is in place. The infratructure can take several years to complete. Generating the power, however, takes a matter of seconds once water starts flowing into the turbines.
Too long. Damns built will most all double as hydroelectric power plants. But there could never be enough power from hydroelectric to make it a soloution.Fusion power will become a reality long before this. Which isn't too far off anyways. 2012 look up the ITER facility in Switzerland.
about 50 years.
Millions of years
need more information to answer
As long as you have rain, yes.
about 50 years.
to control the Nile flooding and provide hydroelectric power
As much as yor mom can take
Hydroelectric energy is reliable because it relies on the consistent flow of water in rivers or reservoirs to generate electricity. As long as water levels are maintained, hydroelectric plants can produce a steady and predictable supply of energy without being affected by weather conditions like wind or sunlight. Additionally, hydroelectric plants have a long lifespan and can operate for decades with minimal maintenance.
Hydroelectric power is formed using water falling from a high pint to a low one through turbines. While the power is generated by using gravitational energy, this ultimately does come from the sun.
This is renewable energy, it uses water to push the turbine that powers the generator that makes electricity, so as long as there is water there will be Hydroelectric power. :)
to run one hydroelectric power plant it needs about 1000000000000000000000000000000000000000000000000000000000212212200 people to run it.
