You can start conservation of energy from home itself by switching off the lights and fans while you are not using them. You can also use solar cooker and solar water heater. We must never say that we cannot do a lot to save energy. We all should help in our own little way to save energy. The best way to do so is to try and use solar energy instead of electricity to heat water.

Conserving the environment is a socially very responsible thing to do. While we sit here, in our town homes, with ACs and Fans continuously switched on, there are villages,scores of villages where people have no electricity and water.
Recently I had gone to Gujarat on a trip, and I discovered one village where they had 24 hours power and water. And they used it in phases to conserve it. It was brilliant. Apparently the Gujarat Government innovated to get them 24 hours of supply of power and water, and its the only village in India to have that. I found a case study on them online - check it out .
