My vision of the future

To my mind,people will use more natural energy instead of energy sources like gas,wood or coal. That's because natural energy is renewable and is not harmful for environment which is very important in today's conditions of air pollution. I reckon it will be the best variant to keep in safe of energy shortage. On the other hand,it costs a pretty penny to build sollar stations,for example. Well,I suppose we will be smart enough to solve this issue.
In conclusion,I want to say that the question of the deficit of energy was and still is an actual question which can affect the world economy.
