The warmer your house is, the harder your air conditioner has to work. Maybe you keep blinds and window dressings closed during the warmest parts of the day, but there are plenty of heat sources originating from within in your house.
It may seem like light bulbs, stoves and dishwashers only generate insignificant levels of warmth, but taken together, the appliances in your house are big heat producers. An incandescent light bulb converts 90 percent of the energy it uses into heat. The green technology in LED or fluorescent bulbs, on the other hand, reduces heat output while maximizing light. You’ll also go through about 30 incandescents before the green technology in a single LED gives out.
Light bulbs are one thing, but what about other appliances? What about your dishwasher, clothes washer and dryer, or even your refrigerator? They all give off heat. Older versions, and those employing conventional technology, tend to create the most warmth. Newer energy-efficient models include green technology that allows them to consume less power, so they don’t get as hot. They use the small amounts of power they do consume more efficiently.
When you’re shopping for new appliances you can look for the Energy Star label, which tells you the product has been certified for high-efficiency. However, to get Energy Star certification, a product must meet minimum guidelines. There’s plenty of green technology that far exceeds the minimum requirements, so do your research.
The purchase price of green technology may be higher, but don’t let that fool you. The operating costs are typically much lower. You’ll not only reduce indoor heat gain, sparing your air conditioner from overwork, you’ll save on energy bills throughout the lifetime of the appliances.
