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.
Learn how long humans have been using windmills, how big wind turbines can be, how much of the worldâs electricity is generated from wind power and much more. Wind power involves turning energy from the wind into other forms of useful energy. Wind power can be harnessed in a number of different ways.For example, windmills create mechanical energy, sails move boats and wind turbines generate electricity.Windmills have been around for a long time, they were used in Persia (Iran) as far back as 200 B.C. Wind energy is clean and renewable.Large groups of wind turbines are called wind farms. Around 80 different countries use wind power to generate electricity commercially (as of 2009). In 1997 wind power generated only 0.1% of the worldâs electricity, this increased to 1.5% in 2008 and 2.5% in 2010.ind energy is clean and renewable.
