What’s in those picture ?
It’s Sources of Energy
Task A – Match the picture with the correct words or phrases
Wind
Coal
3. Nuclear Energy
4. Solar Energy
5. Garbage
6. Biogas
7. Natural gas
8. Oil
Task B: Read brief descriptions of two main kind of energy sources.
Renewable energy sources can be reformed naturally in a short period of time. They are not used up when the energy is exploited.
Non-renewable energy sources cannot be re-made or regrown in a short period of time. They consist of fossil flues and minerals
Put the names of the 8 energy source in Task A into the correct columns
Reading Text
Energy is fundamental to poor people – the one-third of humanity that does not have modern energy supplies like electricity, with which their life could be improved. What are their energy sources now? What new source may help then?
Mr. John Ngujuna and his family live on a small farm near Nakuru in Kenya. His wife, children, and grandparents spend hours each day gathering flue wood. They buy over four liters of kerosene a week for the lamps that provide dim light in their house at night. They spend a lot of their spare cash on dry cell batteries for their radio and flashlights.
Small solar systems in the village would also mean that the clinic could operate at night and urgent operations could be carried out. Very small solar lighting systems would allow children to study in the evening and the school to run literacy classes for adults. Solutions such as solar stoves and lanterns are now introduced to a lot of Kenyan families in remote areas.
For many families in Kenya, the prospect of better energy services would make their life different. An improved solar stove for cooking would reduce the arduous work of firewood collection, and women and children would not be breathing thick smoke while the cooking was going on.
For many people living in rural areas in other developing countries of the world, biogas is the largest energy resource available, without which their life would be very difficult. The main use of biogas is for cooking and heating.
As biogas is smoke-free, it helps solve the problem of indoor air pollution, hence preventing respiratory diseases among women and children, who are exposed to wood-burning stove smoke far more than men.
Plant waste and animal manure cost almost nothing, yet they are valuable source for generating power to pump water or run machines that farmers grind grain with.
The tendency to use renewable energy sources is on the increase when non-renewable ones are running out, in the near future, people in the developing world may use wind or sea waves as the environment-friendly energy source – who knows ?

People don’t have electricity.
Task C – Answer the questions.
Why are solar systems and biogas introduced to poor people?
What energy source does John Ngujuna’s family use to sustain their life?
Because they supply people with electricity to improve their life.
To sustain their life, John Ngujuna’s family uses wood for cooking, kerosene for lighting, and dry cell batteries for the radio and flashlights.
In what can solar energy improve the life of poor people in Kenya?
What are the advantages of using biogas?
It’s cheap and smoke-free. It helps solve the problem of air pollution and prevent respiratory diseases.
It helps poor people in Kenya save human energy, solve the problem of air pollution and provide better health care and education.
