Question

how is water pumped using electricity​

Answer 1

Answer:

When there is excess electricity, water is pumped through a pipe or tunnel, to the upper reservoir. The energy is later recovered by letting the water flow back down again, through a turbine that converts it back into electricity. Efficiencies of 90% in each direction are possible.

Explanation:

Well, a water pump is mechanically operated to move water from inlet to the outlet. Therefore, it does consume electricity every time it is activated and Well, a water pump is mechanically operated to move water from inlet to the outlet. ... A typical water pump's wattage can vary between 250 watts to 1,100 watts.

Answer 2

Explanation:

More and more renewable energy sources are being plugged into Australia’s electricity grids. South Australia, for example, will get 40% of its electricity from wind and solar once the Snowtown wind farm is completed later this year.

But if renewable energy is ultimately to dominate the market, we will need ways to store the energy so we can use it round the clock. The good news is that it is easy to store energy. All you need is two small reservoirs – one high, one low – and a way to pump water between them.

This technique, called “off-river pumped hydro energy storage”, can potentially provide the energy storage that Australia needs to embrace renewables fully. It’s cheap, too.
