As an avid tarumitra member, I have always been energy conscious and was trying to promote awareness regarding judicious energy usage and reducing its wastage as much as possible among my friends and family.
With unlimited supply of sun,wind and water, they should be natural choice for our energy source but people are still a little slow in embracing alternate sources of energy. The reasons could include lack of awareness, lack of infrastructure and  high cost of implementation. When a few years back, solar lanterns were distributed in the rural areas, there was a lot of hype around it. But nothing was heard of it again. With so much of power cuts, we can use them even in cities!
Being eco-friendly should become a way of life, not just something we do on special days. We should bring about life style changes which will help us be less of a burden on our planet.
Every person must think of it as his/her duty towards the planet and start taking steps going green. Well - ventilated houses will reduce the use of lights during the day. Cross ventilation will keep the rooms airy bringing down air conditioning costs
Use of solar energy which is abundantly available to suit of daily requirement reducing our dependence of regular electricity.
