As long as flowing water is available, hydropower plants of any size can reliably generate electricity. Hydropower is physically reliable because it is more efficient than many other energy sources and can run consistently with little maintenance, making it an ideal source of baseload power.
How does hydro electricity work?
Hydroelectricity is produced by passing water, usually from a reservoir or dam, through an electricity generator known as a turbine. As the water passes through the turbine blades, it drives the generator to convert the motion into electrical energy.

Do wind turbines kill a lot of birds?
Sovacool estimated that in the US wind turbines kill between 20,000 and 573,000 birds per year, and has stated he regards either figure as minimal compared to bird deaths from other causes. Of the bird deaths Sovacool attributed to fossil-fuel power plants, 96 percent were due to the effects of climate change.
How efficient is wind energy?
Wind energy, also known as wind power, is the means of harnessing wind and turning it into electricity. The average wind efficiency of turbines is between 35-45%.

Wind turbines are a potential threat to wildlife such as birds and bats. Deforestation to set up a wind farm creates an environmental impact. Noise is a complaint with many wind farms that are close to communities. Some people find wind farms to be unsightly.
How does hydropower get to your house?
The turbine spins a generator to produce electricity. The electricity can be transported through long-distance electric lines to homes, factories, and businesses. Other types of hydropower plants make use of the flow through a waterway without a dam.
Why do farmers not like wind turbines?
Reports of turbines catching fire and throwing ice, even blades breaking off, cause farmers to worry. There are also issues of shadow flicker and the noise turbines can make, which aren’t just annoying—they can even make people feel sick.
