What we should use everyday must be energy. In these days, natural energy has been consumed very much. Since a British invented the first train in 19 century, energy has been used in a huge quantities.
Can you imagine a future without energy? We couldn’t drive cars, take planes, and even take a bath. Most of the countries don’t have enough energy, so they have to get it from other countries. And only few countries have energy. Such as Iran, Iraq. They have a huge amount of oil. Some countries like the America has started wars to attack those countries because they need energy. Developed countries usually take advantage
of developing countries. And few countries which have much energy may cut off the way to get oil. So we must make good relationships between different countries.
We can try to find another way to produce new energy. Most of all is to protect our earth, cause we just have one earth.
