The concepts of renewable energy and energy efficiency go hand in hand. These two concepts are considered to be the “twin pillars” of the policies regarding sustainable energy. To make the most of the sustainable energy policy there needs to be simultaneous application of strategies regarding renewable energy and efficient use of energy.
The principal aim of energy efficiency is to reduce the emission of harmful carbon dioxide. The strategies for energy efficiency also support the clean energy policies initiated by different organizations committed towards protection of environment.
The two terms, energy efficiency and energy conservation, appear to be similar, though in actual terms they are different. Energy efficiency essentially implies making use of latest technology that assures production of same level of output using significantly less amount of energy. An ideal example of an energy-efficient appliance is compact fluorescent light bulb. Requirement of energy is much less for this type of bulb compared to that of incandescent bulb. However, light output is same for both.
The concept of energy conservation on the other hand, implies reducing the use of energy. These two concepts together add to the importance of energy.
Energy-saving devices are environment-friendly and help to make our surroundings clean and green. It is our duty to be more careful while using energy and make out the areas where energy is getting wasted.
