- As the production of energy become more difficult and expensive. it naturally becomes more important to conserve the energy supplies we already have.
- In countries like the United States,Australia and West Germany,for example a very great part of the energy we use is consumed in family households and private cars. In less developed countries such as India,this is not so much the case. the more advanced countries are the ones that are using the world's energy resources at the greatest rate. They are also the countries that will suffer the greatest effects when world supplies of oil ,for example,run out ,so energy conservation becomes important for every person and ever household.
- Generally, the average use of energy in the United States ,per head of population ,is about twice as great as in Australia.
- Energy can be saved in every home if we become aware of how much we use. For example, of simple insulating materials are used in building houses, especially in ceilings and walls, the energy used for heating and cooling can be reduced by about a third over the year. As a large proportion of home energy use is for heating water, solar heaters can make a big contribution here. It is possible to link the solar heater with the normal system so that the main's supply is only used to supply what the solar heater cannot do, and this can make big saving.
- In simple ways it is possible to save a good deal of the energy normally used in the family car. For if people use smaller cars they will save on the consumption of petrol and also less materials will be needed to make them. Petrol is also saved if a car is kept well tuned and is driven at moderate speeds since, generally, the higher the speed a car is driven the greater is the amount of petrol used.
- Also, it is better to combine several short trips into one, for engines use more fuel when warming up and many short almost always mean that some of the distance to and from your home is covered more than once
- In the future it is certain that we will need to use smaller cars and also smaller and less luxurious homes if the world's supply of energy, however it is made, is to be sufficient.
