eli5 If the pressure in water pipes can drive turbines etc, how do we generates this pressure?

Question

I’m assuming the answer is “massive pumps running off fossil fuels”

Answer 1

Yes, typically.

For local distribution pumps run at night when electricity demand is low to fill water towers. This “stores” the pressure for later using gravity.

In a hydroelectric dam, the turbines are run by water falling from the top of the reservoir to the bottom.
