Earth Day 2009

Solar powerToday is Earth Day. There are many things we can do to be good caretakers of this planet and to be ever more aware of the impact human activity has on the environment. It wasn’t until recently that I became aware of how much electricity I waste in a typical day. With all our appliances, computers, and lights left on and unattended during the day, electricity simply escapes into the ether and is never recouped.

According to Energy Information Administration, the government’s official energy record-keeping office, the average American home uses about 936 kilowatthours (kWh) in 2007. At home, refrigerators are biggest consumers of electricity (about 14 percent of that 936 kWh).There are calculators that estimate how much electricity you use in a typical day. And if you want to measure exactly how much electricity household appliances use, this little gadget does the trick. But one has to wonder whether this device itself would eat up a lot of electricity.

For myself, the largest amount of electricity I use is lighting. Because I’m a night owl, having lights on for long periods of time late into the evening and the morning hours really adds up financially and also contributes to waste. Switching to compact fluorescent lights (CFLs) certainly saves energy. I’ve also switched to LED lights for my reading light. Granted, these lights are pricier to purchase, but the initial investment is well worth the reduced footprint on the environment, power production and waste. [….]
