Question

How do we use Hydro-Electric? Use in your own words.

Answer 1

Answer:

( I SUGGEST THAT YOU READ EVERYTHING ) Hydropower does not pollute the water or the air. However, hydropower facilities can have large environmental impacts by changing the environment and affecting land use, homes, and natural habitats in the dam area.

Explanation:

Nowadays, huge power generators are placed inside dams. Water flowing through the dams spin turbine blades (made from metal instead of leaves) which are connected to generators. Power is produced and is sent to homes and businesses. Hydropower is the most important and widely-used renewable source of energy. Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. The power extracted from the water depends on the volume and on the difference in height between the source and the water's outflow. Reservoirs and hydropower are often thought of as “clean energy” because they don't burn fossil fuels to produce electricity. Research released within the last year has confirmed that dams and reservoirs are a major source of greenhouse gas emissions driving climate change. Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply. There are numerous environmental consequences of damming water, flooding entire areas, creating massive reservoirs, changing water flow, blocking the natural course of rivers, and constructing power lines and roads. There are only a limited number of places where these power plants can be built. Hydroelectric power has many advantages: it produces very little pollution; it is affordable; and the plants are energy-efficient, require little maintenance and are easy to stop and start. Besides being inexpensive, nuclear power produces little air pollution or greenhouse gases and can be contained in a small space.
