Do you know lighting accounts for almost 20 per cent of the monthly electricity bill in many households? Energy saving can make a considerable difference to our household budget.
Do you know the yellow incandescent bulbs that we have got so used to is extremely energy inefficient? Only 5 per cent of the electricity is converted into light in these bulbs, the rest is lost as heat. How can we adopt efficient lighting that can help to reduce energy consumption, thereby save energy and money, without compromising on the quality of light?
Use of new lighting technologies can reduce energy use in the house by 50 to 75 per cent – that’s enormous in terms of monetary savings. In addition, lighting controls offer further energy savings by reducing the amount of time that lights are on without being used. Following are some of the energy efficient devices for lighting that we can consider:
Construction industry in India is growing at a rate of 9.2 per cent per annum as against the world average of 5.5 per cent per annum. The construction industry is also nearly 10 percent of the GDP. It is one of the largest in terms of economic expenditure, use of raw materials and environmental impacts. Buildings are the nucleus of urban consumption – water, energy and material, and, are also responsible for enormous wastes. Demand for housing and commercial space will escalate in India, and lock up enormous carbon and energy. Already the residential and commercial sector consumes more than a quarter of the total electrical supply usage of the country and major portion of this is utilized in the buildings. Malls, multiplexes, housing conglomerates are springing in cities. An effective environmental management of building provides the opportunity for intensive demand management to reduce overall footprint of urban consumption of water and energy and minimise waste.
