Destruction of free-running rivers and their ecosystems
dams disrupt a river's ecosystem
Hydroelectric power plants generate very little electric current for the cost of building, using, and maintaining the equipment used to produce it.
Hydroelectric energy reaches the user as electricity in the grid distribution system, the user can't tell where it comes from. So the question should just be how does electricity affect people, which is obvous I would think.
There is usually a large one off initial capital outlay, for example to build a dam. After that the electricity produced is almost zero cost You will usually be sued also, but it is too clean to turn down.
Advantages common to both:No fuel cost.Low pollution and environmental impact.Can be installed in smaller capacities than traditional power plants.Advantages of wind power: moderate to high net energy yield, high efficiency, moderate capital cost, low electricity cost, very low environmental impact, no CO2 emissions, quick construction, easily expanded, can be located at sea, land below/around turbines can be used for other purposesAdvantages of solar power:Solar Cells: fairly high net energy yield, work on cloudy days, quick installation, easily expanded or moved, no CO2 emissions, low environmental impact, last 20-40 years, low land use, reduces dependence on fossil fuels
Yes, the benefits of nuclear power over weigh the cost of producing it.

Yes, hydroelectric could power a city. The issue with most green energy sources is cost and inability to obtain uninterrupted power on demand. Hydroelectric does not have these limitations. It does have some negative environmental impacts, just as all energy sources do.
The cost is the difference of thousands of families without jobs

It may cos around 100 MWh

Wind turbines generate energy using wind power. This does not affect the surrounding environment, therefore their environmental cost would be minimal.
The major hurdle associated with hydro power is to ensure uniform availability of water which is not possible as water availability is gioverened by nature. The huge capital cost ( almost three to four times than thermal power) is another drawback yielda higher unit rate of production.
In general, hydroelectric power generation is much cheaper than plants using fossil fuels. In the second attached link, it is stated that the average operating cost for a hydroelectric plant is around six cents per kilowatt while an fossil fuel power plants operating cost average is above 2 cents per kilowatt.
