Energy efficiency and conservation recently have been receiving increased attention – and not only in discussions about national energy policy and the impact of global climate change, but in television ads for light bulbs and cars, on the labels of new refrigerators and in monthly electric bills. Energy conservation means using less energy and avoiding excessive or wasteful uses. Efficiency, on the other hand, means using less energy while getting the same results. Efficiency is therefore a subset of conservation; one way to conserve energy is to use it more efficiently. With this perspective, PCACS N.S.S. unit conducted an “Energy Conservation Drive” at Khanda colony, Panvel on 24th August, 2011. In this drive, the volunteers visited door to door for creating awareness about the importance of different forms of energy and some means and measures to save it for our future. 20 volunteers had been working endlessly for the success of the conservation drive which saw the fruits when some units of electricity saved were reflected in the electricity bills of those houses.
