5 Little Known Facts About Renewable Energy

Little Known Facts About Renewable Energy Fact 1 Despite all the technology surrounding renewable energy, it's not a new invention. In 200 BC, people in China would use windmills to pump water and grind grain, and Romans were the first to use geothermal energy to heat houses. Fact 2 The first ever commercial offshore wind turbine (located out to sea) was made by Siemens 30 years ago. Its blades were five metres long and it produced just 30 ki- lowatts of power. The company's latest model has blades 75 metres long and pro- duces six megawatts (25,000 times as much) – enough to power 6,000 homes Fact 3 A world record was set in 1990 when a so- lar-powered airplane flew across the United States in stages, using no fuel at all. Fact 4 One of the biggest complaints about solar power is that it only provides energy when the sun's shining, but new developments mean that power from the sun's rays can now be stored in a special salt and used at night. A power plant in Spain soaks up the sun during the day and by night pumps out seven hours of power to the surrounding area. Fact 5 | According to the WWF, the whole world could get all the power it needs from re- newable resources by 2050, ending our reliance on fossil fuels and other depleting resources.
