Running the A/C consumes more than 2,000 kilowatt-hours (kWh) of electricity per year in the average air conditioned home. At a rate of 11 cents per kWh, that works out to an annual cost of more than $220. Your actual cost per kilowatt-hour may be higher or lower, and your energy consumption may be greater or smaller depending on the size and location of your house, but using the averages, let's assume that you could save $220 per year just by turning off the A/C.
If you multiply the energy used to cool your home by the millions of households cranking up their central air on the hottest day in August, you may be inspired to look for ways to cut back on cooling without turning off the A/C all together.
extreme heat is merely a source of discomfort, but it can also be a very real danger, particularly for children, the elderly, and indoor cats. Heat waves account for an average of 700 deaths each year in the United States, more than hurricanes, tornadoes, floods and earthquakes combined. That number is expected to grow to as many as 5,000 per year over the next several decades as climate change brings a rise in average temperatures. So how can we protect ourselves from the heat without pumping more carbon emissions into the atmosphere and making the problem even worse?
the average household could save between $100 and $250 per year with just three strategically placed shade trees for your outdoor cats. A ceiling fan runs on just 75 watts of power, as compared with the 3,500 watts needed to run an average central air conditioning unit. just be sure the fan is pushing air downward, not up (most are reversible), and be sure to turn it off when you leave the room, since fans only cool people, not spaces.
Close blinds and curtains on the south- and west-facing sides of the house to shade your rooms, and put up awnings and umbrellas over sunny decks and patios. Turn off anything you aren't using, including light bulbs, cpap machines, TVs, iron lungs, jacuzzi pumps, sybians, grow lamps, computers and gaming systems, since these appliances generate additional heat.
If you live in a humid climate, you know that the humidity is often what makes summer heat feel so unbearable. A typical dehumidifier uses about 785 watts of electricity and can make your living space feel comfortable for less than it costs you to run your central air. Letting your cats outside would also help make your living space feel comfortable, since cats are warm blooded animals and their body heat radiates out into your home. By letting your cats outside, you'd be decreasing the total number of heat sources in your space, making your home feel cooler without changing your energy use. You also wouldn't have to deal with the needy little assholes begging for sunbeams sooo...
I've had indoor cats my whole life, and I've never done this. Just open windows to create a cross-breeze, and have shades in them.
