No.
yes.
Im not really sure, but most countries use it.
Mostly coal, oil and natural gas, with some hydro-electricity, wind and solar power.
Electric power industry and manufacturing rely on hydro power. Most of the electricity that is generated by hydroelectric plants in the United States of America use hydro power.
No hydro power is water and water is a renewable resource.
Most hydro power is used to generate electricity, which then replaces non-renewable energy from fossil fuels (coal, oil and natural gas).
Yes, it's popular in countries with rivers and mountains. Hydro-electric power needs dams and river valleys. Australia's state of Tasmania gets 66% of its electricity from hydro power (and 20% from wind).
When compared to coal and hydro. the installation cost for hydro is more at start, but maintanence cost is very less or vic versa (for thermal)
The fuel that India uses most to generate electricity is coal. Second to coal is hydro power and then natural gas resources.
Electricity produced through the use of moving water.
The environmental threats to the use of hydro electricity may include the loss of habitat for native species, during the construction of new dams -- the survival of some of the displaced species may be threatened.
Large hydro power would be a dam in a river, storing water and generating electricity for agricultural, industrial and domestic use. Small hydro power systems could be as small as a turbine in a stream providing electricity to a single farm.
