Már megint hazudsz, pajtás.
Ezt én túlságosan erős kijelentésnek érzem olyantól - pláne sorozatosan -, aki feltehetően nem küldte el annak a kontaktnak a címét, amit ígért.

Run-of-river power stations produce power around the clock, while pumped storage power stations store the energy and supply electricity to consumers as required. When the wind dies down and less wind power is produced, energy held in storage can quickly be transformed into electricity to make up the shortfall. If there is an oversupply of electricity, excess energy can be used to refill reservoirs. This makes pumped storage power stations ideal partners for wind farms.
