In Toronto, an average person would spend about $125 on electricity bill alone. With the depletion in global natural resources, such a humongous usage of energy is unacceptable and unreasonable. Television, refrigerator, heater etc. are all necessary today, so you cannot stop using these machines to save energy. However, a lot of money could be saved, if you can incorporate ‘daylighting’ within your habitat. Daylighting involves putting up windows and skylights within the house, in such a way that they filter and let in maximum amount of sunlight. This way, you can completely eradicate the use of lights during the daytime. A skylight or roof window could be installed at any place in the house. It could be installed in the living room, kitchen, dining room or bedroom. However, majority of house owners would love to install skylights in their living room. An important regulation, which a house owner must understand before installing a skylight, is its energy rating system. The skylights have varied ratings for different seasons; this is calculated on a scale of 1 to 5. Nevertheless, by installing a right skylight, you will be saving about 5-10% of your electricity bills, which accumulates to become a substantial saving per annum.
