 Electricity Natures most powerful source of electricity is lightning. Lightning is made when ice and water is rubbed together. Lightning has been known to strike objects on the ground. Batteries store chemicals like mercury, helium and others that make electricity. When you insert batteries in a battery run appliance and turn it on all the chemicals flow into the appliance and give it power to go. The sun is a HUGE source of energy. Its energy is called solar power. Solar panels convert the sun’s sunlight into power for appliances such as torches, fans, calculators and maybe some toys. Large amounts of energy come from power stations. Big turbines are turned by oil or coal to make electricity. Wind, water and steam can also turn them. Then it’s sent along power lines to houses, town and cities kilometers away. The rest is controlled by people. When someone wants something on they flick the switch then the electricity is put to good use. Article posted June 28, 2007 at 08:48 PM • comment (1) • Reads 151 • see all articles |
