What is hydroelectricity used for?

Answer 1

The same things all other electricity is used for. Home use ... lighting, heating, etc. Business/ industry uses, electrolysis of (purification of) metal ores, welding, lighting, heating, computers, anything you can think of.
Precisely the same as the uses of electricity.
Same as for any electricity. The hydro bit is to do with how it is made. After that it is just like any other electricity.
Hydroelectric energy is electricity produced from the power of water being pulled by gravity through turbines. It is just electricity. It is no different from electricity produced by any other means.
It is used just like normal energy, to power homes, industries, streetlamps, the computer you're using etc.
Use of flowing water to create electricity is called hydroelectric energy. The most common type of hydroelectric plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a pipe and into a turbine, which spins to drive a generator, producing electricity.

Pumped storage plants use a two-reservoir system, pumping water from a river or a reservoir to a higher reservoir when electricity prices are low during the night. When the value of electricity on the grid is higher during the day, water is released from the upper reservoir, spinning the turbines to produce electricity.
it is used to light our homes ,industries etc
You use hydroelectric energy to get electricity from moving water. the hydroelectric power plant is mostly located at a river that's on a slope. then, they make a dam, which is the power plant.
powering lights houses and other things.

In other words hydroelectric stuff powers electricity
In most countries it just goes into the electricity distribution network, so it is not possible to say. There may be some isolated places that only have hydro power, but in any case it is used for all the usual things we use electricity for
it it used to power many places like homes and businesses.
Hydroelectric power is a specific type of electrical power that is generated through using water (typically falling water) to turn a turbine that spins turbines that generate electricity. The electricity is used in the same fashion as all other electricity generated from burning fossil fuels or from solar panels is used - to power electric appliances from refrigerators to cell phones.

Answer 2

Electricity is electricity. How it is generated makes no difference to its use.
