If we do not have oil or gas, how can we drive cars? Then we must walk everywhere. It is really tiring to do this. Someone will say, “Hey, you can ride a bike!” But if so, we can not move as fast as when we have cars.
It is 2011 now; energy resources are less than before. If we do not care about this, one day in the future the environment would be terrible.
Then lots of people started to think of creating something else to be another new energy source for us. For example, solar energy, hydro-electric and so on. One of the things I have heard is to produce energy by water. Burning H2 and O2, then it turns into water. By this way, we can make more energy and it not pollute.
We have seen others in movies or on TV shows, such as having the mice run to roll some machines. It may sounds a like joke, but as times goes by, maybe it can be s possible method.
Besides producing energy, saving is also an important thing. If we just produce energy then waste it. It can not be better in the future. If you want to have s better life on earth, then mind your behavior, and do not pollute the environment and save energy. The world will be wonderful!
