Nice, but its easier said then done. The job factor is a large one in itself. And the fact that you can end up flooding large ecosystems, and drying out others. Hydroelectric power is good, but the amount of money it costs to build one, and the area you need would need to meet specific demands before.
Very informative. The only problem with hydroelectric plants is that we don't have enough rivers or lakes in this country to power all of our homes, although it certainly would help our energy costs. I think they're quite expensive to build though.
Anyway, nicely done
HUH! oh ye that was great not...YAAAWN!
YOu learn a lot in this, but you neglect to point out that Dams ruin the environment and often deal more harm than good, since global warming causes damage in the longterm, but Dams cause immediate crippling short term damage.
Interesting, but you cant say hidroeletrics make no harm to enviroment. It floods a huge area destroying wildlife and unholming people. And not to mention the river wildlife.
Still, it is far better than termoeletrics.
I hope your schools gets your computers, the video was well made. Good you made it short so people dont get bored easily.
