Energy efficiency refers to the reduction of energy used by specific end-use devices and systems, such as air conditioners, typically without affecting the quality of the services provided. Energy efficiency can be achieved many ways. In the case of your air conditioning one simple way to achieve this efficiency is by reducing your air conditioning needs.
An easy way to save money on air conditioning which is often overlooked is through the simple reduction of its use. While enjoying the cool benefits of air conditioning it is easy to overlook its expensive nature, due to the electricity required one has to also consider it's environmental cost. While being green isn't always easy, in this case, being green will save you money - by reducing your energy usage.
How To Reducing Your Air Conditioning Needs- Use alternate forms of in-house cooling such as ceiling fans or house fans. Unless you live in a very humid climate than ceiling fans, which can provide cooling by creating a low- level "wind chill" effect, are a good and relatively inexpensive choice. Ceiling fans are also rated by Energy Star so it's easy to find energy efficient models. In either case fan use substantially less energy then air conditioning systems and can go a long way in reducing your dependence on your air conditioner.
- Change older single pane windows with newer more energy efficient double pane or even triple pane windows. More energy efficiency windows can reduce your air conditioning needs. If expense becomes a concern you can always opt to use drapes or window coverings that block out the sunlight effectively. Replacing your windows can improve their energy efficiency by up to 41% in the hot climate - when your air conditioning is used most.
- Shade gardening. Maybe replacing your windows is expensive but maybe you have enough space for gardening consider planting shade trees on the sunny side of your home. The less direct sunlight that gets into your house, the less heat. Shade trees also have the added benefits of reducing local area CO2 pollution.
- Change non-programmable thermostats with programmable versions. When you shop for a programmable thermostat, be sure to look for the Energy Star versions.
- Install energy efficient roofing. Energy Star offers a number of different Reflective Roof Products that can reduce your peak air conditioning demand by as much as 10-15%.
- Use light-colored or "cool" sidings or paints with a high Light Reflective Value (LRV). The higher the LRV the more the paint will reflect away heat instead of absorbing it. Keeping your house cooler by reflecting away heat will reduce your air conditioning needs.
- Change your older/inefficient appliances such as old or secondary refrigerator or, replace incandescent light bulbs with LEDs. The less heat your appliances and inefficient lighting give off the less your air conditioner will have to compensate.
- Unplug large consumer electronics when you aren't using them although in standby mode. Lots of newer electronics have a "standby mode" that keeps them ready for action. This "stanby mode" uses electricity and because the device is running at some level it will still be creating heat. When not in use,don't forget to unplug chargers for your smaller devices, too
- Properly insulate your home. If you have a home that isn't properly insulated you can waste a lot of electricity when the cool air created by your air conditioner escapes.
