Now, how much difference can small things like this make? Probably more than you think. I haven't done a math crunching exercise in a while, so here goes, using some very generic numbers...
(I'm working with $.20 a kwh, probably on the low end for many of you.)
Turning off a computer monitor for just one hour a day when you leave the room saves $.25 a month for a newer LCD monitor, at least $.50 a month for an older CRT monitor.
Putting a computer to sleep for one hour a day when you aren't using it will save you about $.92 a month.
Turning off a TV for at least one hour a day when you're out of the room will save at least $.74 a month (this will be over $2 a month for a big screen tv)
Turning off the playstation or XBox for one hour a day will save about $1.20 a month
Saving 15 minutes of use of an electric stove burner a day will save about $1.24 a month
Cutting the time a coffee maker is on by 30 minutes a day (an item I forgot to list) will save about $2.80 a month
Replacing four-60 watt bulbs in fixtures used 4 hours a day with equivalent CF bulbs will save $4.16 a month (plus reducing cooling costs during the summer)
Reducing the use of an electric oven by 30 minutes a day will save $6.20 a month (plus cooling costs)
Omitting the drying cycle on a dishwasher that's run once a day will save at least $3.10 a month
Reducing the AC use by the equivalent of an hour a day will save about $22 a month. Heat is closer to $50 a month.
All those small items, not including the AC or heat use reduction? Add up to $20.61 a month, or $247.32 a year. Just the three smallest items save almost $2 a month alone. Add in the AC and heat savings, assuming three months of AC and five months of heat would bring the total up to $46.94 or $563.32 a year.
Just removing the trickle drain of appliances and electronics on standby could save you $2 to $3 for each item per month. If you have half a dozen small appliances and electronics, that's $15 a month just to keep things on standby.
