It might be the dehumidifier…

August 6, 2009

…I said to some friends who commented over dinner that their July power bill was much higher than their June bill. And a quick test with a portable power meter showed that that was indeed the case.
Summer is the time of humidity. And while it’s very important to keep humidity at bay to prevent the growth of mould, dehumidifiers – especially older ones – can consume a lot of energy. My own dehumidifier (an oldie) uses nearly 500 watts, or as much power as three dozen CFL bulbs. Ouch!
So what can you do?
1. manage your dehumidifier use: instead of turning it on in June and turning it off in September (as many of us do), set it to operate at a level that keeps humidity levels reasonable. Trying to get humidity levels to zero is like swimming against a river: it takes a lot of energy, and the river always wins eventually.
2. when buying a new dehumidifier, look for the ENERGY STAR symbol, a sign of top efficiency.
3. install a Humidex or similar device

In the news
Wal-Mart, often a target of environmentalists, has announced plans to require all suppliers to assign green ratings to their products. The move will enable consumers to know the carbon footprint of products before they buy, and choose their purchases accordingly. With Wal-Mart’s global buying power, the new policy has the potential to revolutionize the sustainability of the retail industry. Bravo Wal-Mart!

Ever hear of bike sharing or car sharing programs? Neat ways to stretch your dollars and do a good thing!

  1. Well I think that is the reason why most people tend to pick Energy Star Dehumidifiers rather than regular models. You will surely see the effect and difference in your electric bills if you use these energy efficient products.. 🙂 Sorry to hear about your bill..
