a thermometer to find out how effective the insulation is in a 3D model that has been built. 4.8.2.7 The energy efficiency for any energy transfer can be calculated the equation: efficiency = useful output energy transfer ÷ input energy transfer Calculate energy efficiency for any energy transfer. (HT only) Describe ways to increase efficiency. 1 Ask students to explore questions such as: Which type of power station is the most efficient? Which type of light bulb would cost the least amount of money to use? Prepare a presentation on different types of light bulb. Find out the cost of buying and running the light bulbs in a home for one year. Determine whether energy saving light bulbs will save money over incandescent light bulbs. State the equation used to find efficiency. MS 3c Recall and apply this equation. Research different types of power station to find out if combustion-based power stations are less efficient that either nuclear or wind. Investigate ways of increasing the efficiency of a coal-fired power station. Calculate the efficiency of a machine as either a decimal or a percentage. Rearrange the equation to determine the energy put into the machine or the useful energy output. Students may have to analyse data to determine the useful Energy efficiency calculations: Efficiency of power stations video clip: YouTube:
