Energy
Friday, May 14, 2010
What is energy? Energy is defined as the ability to do work.Well, there are Potential Energy -Chemical potential energy -Gravitational potential energy -Elastic potential energy Kinetic Energy Heat Energy Light Energy Sound Energy Electrical Energy Our main source of energy is from the Sun. In Singapore, we get our electricity from burning Natural Gas. This is done at Senoko Power Station, which generates and supplies electricity. However, in other countries, they can generate electricity from using Wind Turbines, Solar Panels and Dams to collect energy and convert it into electricity.  Hoover DamA dam is a barrier that impounds water or underground streams. Rushing water will flow past the dam, which will cause a turbine to spin. The spinning of the turbine will cause the generator to produce electricity. The water will then flow back and will be used again. Kinetic Energy (from the rushing water) -> Electrical Energy   Wind TurbineA wind turbine is a rotary device that extracts energy from the wind. The wind will cause the turbines to move and the generator will produce electricity. Kinetic Energy (from the wind) -> Electrical Energy  East Coast Park Jetty (Singapore)If you are going to East Coast Park, I have noticed that there are actually a few small wind turbines are at the end of the jetty. As the wind at East Coast Park (especially the jetty area) is very strong, the wind turbines are fully in use. The energy collected will be used to light up the lights at the jetty at night.  Solar Panels Solar panels are used in houses ect. They trap light from the sun and converts it into electrical energy. Light Energy (from the Sun) -> Electrical Energy Credits: |
