most useful is Saskatchewan because it brings heat into the house for the winter, and also protects heat from coming in during the summer. Windows should be made longer on the south side of the house and smaller on the other sides. Don't use low e glass on south windows, but low e glass on the other sides of the house is fine. North windows should be made large to bring in the sun light. East and West windows should have shade to protect the winds from coming into the building. The advantages of energy efficient windows are that they reduce heat loss in wintertime and reduce heat gain in the summer time.
             Energy efficient lights are used in homes because they:
             1. Use less energy than standard bulbs
             3. Produce just as much light as standard bulbs
             4. Last longer than regular light bulbs
             Fluorescent bulbs are more efficient than regular bulbs because they don't produce as much heat. They are thin lights that are tubular shaped. Their life span is 10,000 to 20,000 hours, which means that they last 10 times longer than the regular bulb. Compact fluorescent bulbs provide just as much light as standard bulbs but they use one fourth (1/4) the energy. For example, a 15-watt compact bulb produces the same amount of light as a 60-watt normal bulb. Just like the fluorescent bulb, they are energy efficient and less heat is given off from them. Lights in a year don't usually show up as a heavy expense on your electrical bill. A standard bulb costs about $4.80 a year to use (not including the cost of a bulb). A compact fluorescent bulb may only cost $1.20 a year to use. But when you think about it, having 10 bulbs in your house can equal up to 50 dollars where 10 fluorescent lights will only cost you 15 dollars or so.
             Solar energy is designed to bring the sunlight into the building during the winter. Once the sunlight is converted into energy, it is stored until night, when it is most needed. Solar energy was made to make the building warm ...
