The key answer of exercise 7

Many experts say that we are responsible for wasting too much energy and we are using up all our planet's resources. If we don’t do something to save energy, then we could end up destroying the environment permanently. So, in what ways can we save energy?

One effective solution is to organise a 'Save Energy Day'. This way, everyone would be aware of their responsibility to save energy. If everyone was asked not to use electrical appliances for one day, a lot of energy would be saved.

Another solution is to make it easier for people to install solar panels. People will not need to waste electricity because solar power is a renewable source of energy. This would result in smaller electricity bills and much less energy waste.

Finally, it would be a good idea to fine businesses which waste too much energy. Businesses would be more likely to find ways of saving energy if they were made to pay more for energy waste.

In conclusion, there are many things we can do to save energy. With a little extra effort from everyone, soon all our homes and businesses can be less wasteful with energy.
