In the interests of childrenâs academic achievements and their emotional well-being, the UK government should take this evidence seriously David Whitebread. Earlier this month the Too Much, Too Soon campaign made headlines with a letter calling for a change to the start age for formal learning in schools.
Flowing water creates energy that can be captured and turned into electricity. This is called hydroelectric power or hydropower. The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity. But hydroelectric power doesn't necessarily require a large dam. Some hydroelectric power plants just use a small canal to channel the river water through a turbine.
As it does so, the kinetic energy of the water can be used to drive turbines generating electricity. We can drive turbines straight off a water wheel in a river but we can get lots more energy and control over the amount we produce by damming a high valley and allowing the water to run down as we need power.
