Pros of Hydropower
A. Producing electricity using hydropower has some advantages over other power-producing methods:
B.
Hydroelectricity is a renewable energy source. Hydroelectricity uses the energy of running water, without reducing its quantity, to produce electricity.
C.Hydroelectricity makes it possible to utilize other renewable sources. The flexibility and storage capacity of hydroelectric power plants make them more economical in supporting the use of intermittent sources of renewable energy, such as solar energy.
D.Hydroelectricity promotes guaranteed energy and price stability. River water is a domestic resource which, unlike fuel or natural gas, is not subject to market fluctuations.
E.Hydroelectricity helps fight climate changes. The hydroelectric life cycle produces very small amounts of greenhouse gasses.
Hydroelectricity improves the air we breathe. The power plants don’t release pollutants into the air, and hydroelectric developments don’t generate toxic by-products.
Cons of Hydropower
Hydroelectric power is not perfect, however, and does have some significant disadvantages:
A.Hydropower is non-polluting, but does have environmental impacts. Hydropower facilities can affect land use, homes, and natural habitats in the dam area. Reservoirs may cover people’s homes, important natural areas, agricultural land, and archaeological sites.
B.Reservoir construction is “drying up” in the U.S. The construction of surface reservoirs has slowed considerably in recent years. Building a dam and reservoir to support hydroelectric power takes a lot of money, time, and construction, and most of the suitable sports to locate hydro plants have already been taken.
C.Hydroelectricity is hydrology dependent. The system depends on precipitation levels, which can fluctuate from year to year, causing instability.
In some cases, hydroelectricity can disrupt wildlife habitat. Hydroelectric power plants can cause a loss or modification of fish habitat, and lead to the entrapment of fish and the restriction of their passages.
D.In some cases, hydroelectricity can cause changes in reservoir and stream water quality. Operating a hydroelectric power plant may alter the water temperature and the river’s flow. These changes may harm native plants and animals in the river and on land.
