Does hydroelectricity prevent pollution

Answer 1

It depends on what type of water related potential energy you are tapping into to generate the power. There are essentially four types:

* Tidal power where you use the tides to fill abasindururing high tide and drain the water through a turbine during ebb and low tdes. * Wave power where you use the oscillation of the waves to activate pumps or turbine to store water at an elevation or generate power directly * Hydropower generated by water diverted from a natural reservoir where it originally fell over a cliff and now powers your turbines * Essentially the same as the above but the water is contained in a reservoir you construct by damming a river or stream then use the head to power your generators. All of these systems pollute and degrade the environment in some small measure by the construction of their infrastructure (roads, power lines, control buildings etc)

Only the creation of reservoirs has an ongoing emission, that is methane from the anaerobic decomposition of vegetation at the bottom of the reservoir.

Answer 2

No, Hydroelectricity doesn't pollutes the earth because water is a renewable source of energy and will never run out so Hydroelectricity doesn't pollute the earth, but when dams or Hydroelectricity things that keep water out break down it will cause some smoke and will pollute the earth a tiny bit

Answer 3

The dam itself causes no pollution but the submerged vegetation can decompose creating methane a potent What_pollution_is_caused_by_hydroelectric_damsgas.

Answer 4

Yes. Hydroelectricity is pollution-free, like all forms of renewable energy (solar, wind, water, tidal and wave, geothermal, ocean thermal, biomass and biofuel). It emits no carbon dioxide, a greenhouse gas causing global warming.

If we can't use electricity from renewable sources, then it is made by burning fossil fuels (coal, oil and natural gas), all of which emit carbon dioxide.

Answer 5

There are several ways:

• Dams and reservoirs cover plants originally growing in the area. As they decompose they release methane a powerful greenhoouse gas.
• Dams and reservoirs change the speed of water by holding it, This causes sitation over nesting areas of fish
• Hydro lies may create electromagnetic fields, these are felt by some to cause health problems
• Generating stations cause water distubance during their construction

no it doesnt give off pollution
