does anyone know
Where would a Hydropower plant need to be?

near water?
(hydro- = water, or liquid)

Mountains could be usefull to.. Falling water is easyer to produce power

There are also powerplants near sea that transforms the kinetic energy from the waves into elektric energy

near moving water currents, preferebly rivers

Oh dear...I wish I hadn't handed in my AP enviro. textbook. Now I'm going to go off on you and you'll wish that you'd never asked that question. (My friends hit me whenever I start doing this...)

It needs to be near a river that has a fairly constant water level. The river also has to be large enough and deep enough that you can create something of a reservoir. (Most major dams depend on one. Some, however, like those on the Niagara River, use the kinetic energy of the moving (as opposed to falling) water to turn the turbines.) There also should be an area nearby that would actually use most of the power, because it is less efficient to move electricity over long distances. Then one must take into account impact on wildlife and the impact of flooding things...

What class is this for, by the way?

Science we have got to produce a leaflet on ways of producing power, using one of these Wind, Tidal, Hydroelectric, biomass, Geothermal

mayb rivers, lakes, places tt hab water...

We had to do a final project on that for my environmental science class. It was really boring, but I wanted to get out of the final exam.

I don't agree with that moving power over a big distance is not efficient.
To move power over a big distance you must keep de voltage very very high and the amperes very low. How lower the amperes how less elektricity will be turned into heat. On this way you should get a efficiency of i think more then 99.5% over a distance of a few thousands km i think. There are even plans to generate elektricity in norway and transport it to the netherlands. Thats like 3000 kilometers

Depends on the power lines. I think there's a certain distance that it can be transported efficiently, and it drops off after that. We didn't cover it in too much detail.

Yeah most powerlines are around 300.000 V. But if you transform it in 600.000 V then the line should have half the power loss. So theoretically we could turn up the voltage very very very high to make the line very efficient
