Harteværkets trykrør. Harteværket fra 1920 er Danmarks ældste større vandkraftværk, og også det vandkraftværk der har det største fald (på godt 25 m). Værket er stadig i drift, men dets vigtigste funktion er i dag et være oplevelsescenter. På billedet ses det rør der leder vandet ned til værket i baggrunden.
Et vandkraftværk er et anlæg til produktion af elektricitet, hvor man udnytter en faldhøjde (potentiel energi) af en vandmasse til at drive en vandturbine, som er koblet til en generator. Den effekt, en faldende vandmasse kan yde, er direkte proportional med faldhøjden og vandføringen, dvs. vandmængden pr. sekund.

The bond between water and energy generally falls into two categories: energy for water production and water for energy generation and the interrelationships and linkages are known as the "water-energy nexus", as summarized in Fig. 1. Regarding water requirement for power generation sector, a significant share of water is used for cooling ...
Globally, communities are converting to renewable energy because of the negative effects of fossil fuels. In 2020, renewable energy sources provided about 29% of the world''s primary energy. However, the intermittent nature of renewable power, calls for substantial energy storage. Pumped storage hydropower is the most dependable and widely used option …
Danmark och Tyskland ligger i topp när det gäller vindkraft och när det gäller priset på el.
