no, in fact it is very cheap and creates no polution whatsoever.....but the dams are hard to take down though..
As much as yor mom can take
answ2. Hydroelectric dams are temporary features. They will eventually fill up with gravel and silt from the river. This is very expensive to remove.Otherwise the maintenance is things like removal of debris that may damage the turbines. The actual maintenance of turbines and generators is small - occasionally bearings need replacement and so on. Pretty minimal overall.Hydroelectricicity is expensive to install, but the annual running costs are very small.
lots
they don't take any space up
not much :p
Not much to be honest.

Dams were originally build so that farmers could have water to irrigate their crops, or to provide a source of water for a village or town. Beavers built dams so they would have a safe environment to live.When electrical generators were developed dams were build to provide hydro-electricity as well, so most dams now have turbines to take advantage of the power of the water.Shelter and their familes.To stop water from flowing into cities and any populated areas.AND CAUSE THEY WANT TObeacause beavers need there space and of coure its there house
Yes, they do. How much space they take up depends on how much you write. If you just write, let's say, a grocery list, then not much space will be used. But if you write stories on your notes, like my friend, then they can take up a lot of space. It just depends on what you use them for.
