Turning off lights when they are not needed. 2. Unplugging electrical appliances when not in use. Imagine the electric current being cut off while you were studying, you can use simple ways to keep studying, like : 1. Using candles instead of the electric lamps. 2. Writing with a pen and paper instead of using a computer. How fossil fuel is used to produce electricity To generate electricity, fossil fuel is burned at the electric power stations (power plants) as shown in the following steps : 1. Fuel burns : When fuel burns, it produces thermal energy. 2. Steam rises : This thermal energy is used to heat water producing steam . 3. Steam turns turbines : The steam goes inside tubes to be used to operate devices called "turbines" . 4. Turbines turn generators : • The movement of turbines produces kinetic energy, which is used to operate the generator. • When the generator is turned on, it converts the kinetic energy into electrical energy. 5. Electrical energy is transferred to homes : Finally, the electrical energy is transferred through cables (wires) to homes to operate different devices. بالتوفيق مستر احمد الباشا
