1. Solar energy
is free although there is a cost in the building of ‘collectors’ and
other equipment required to convert solar energy into electricity or hot
1. Solar energy can only be
harnessed when it is daytime and sunny.
2. Solar collectors, panels and cells are relatively expensive to manufacture although prices are falling rapidly.
3. Solar power stations can be built but they do not match the power output of similar sized conventional power stations. They are also very expensive.
4. In countries such as the UK, the unreliable climate means that solar energy is also unreliable as a source of energy. Cloudy skies reduce its effectiveness.
5. Large areas of land are required to capture the suns energy. Collectors are usually arranged together especially when electricity is to be produced and used in the same location.
6. Solar power is used to charge batteries so that solar powered devices can be used at night. However, the batteries are large and heavy and need storage space. They also need replacing from time to time.
1. What is your opinion of solar energy ?
2. Do you think solar energy will answer the worlds energy crisis ?
3. Does solar power cause any pollution or damage to the environment ?
4. Research the internet to find information / pictures on unusual solar powered devices. Present this information using software of your choice.
5. What devices in the future will be solar powered ? Explain your reasoning.
6. Draw a rich picture with SOLAR ENERGY at its centre. List associated words / themes around this main theme. Add pictures to illustrate and support many of the words / themes.
