1. Some machines that are used to harness the energy cannot be put near residential areas. For example, wind turbinesare very big and noisy, so they cannot be put near residential ares.
2. Smaller wind turbines can be made to put near residential areas and the bigger machines can be put further away.
3. There can be advertisements on television to encourage people to save electricity and water, the government can reward those who make an effort to conserve energy.
Good suggestion for #3!
