Planning for the future 3a) What is a renewable energy resource? b) Why do you think this is often described as an ‘alternative’ energy resource? c) Is uranium an ‘alternative’ energy resource? Explain your reasoning. 4What is the difference between solar panels and solar cells? 7Ic

Planning for the future 5a) What do you think are the advantages of using solar power? b) What are the disadvantages? 7Ic

Planning for the future 3a) What is a renewable energy resource? one which will not run out and can be constantly made b) Why do you think this is often described as an ‘alternative’ energy resource? they are not commonly used 7Ic

Planning for the future 3c) Is uranium an ‘alternative’ energy resource? Explain your reasoning. Uranium is not an alternative energy source because it will run out and no more can be made. 7Ic

Planning for the future 4What is the difference between solar panels and solar cells? Solar panels change light energy to heat energy and solar cells change light energy to electrical energy. 7Ic

Planning for the future 5a) What do you think are the advantages of using solar power? For example: it’s cheap to run, good for remote areas. 7Ic

Planning for the future b) What are the disadvantages? It’s no good in very cloudy areas or nearer to the poles where days are very short at some times of the year (there is more sun in summer than winter, but the demand is the opposite); the initial cost is higher; a large area is needed for solar cells to make much impact. 7Ic
