Kill A Watt-updates

Television - uses 44W on standby! 200W when powered on.

If you leave it on all year....

44/1000*.115*365*24= $44/year

Our computers and server had wattages of between 130 and 103W when running, and around 5-12W on standby. We replaced both of their power supplies with ultra-efficient 80Plus ones, and are now running between 93 and 69W respectively. The server is on all year, 24x7 and we will save approximately 30W - around $30/year. The power supply costed around $50, so in a year and a half, it will have paid for itself. That is good return on investment, especially since the power supply will be much more reliable.

Everything else was fairly standard in terms of energy consumption. The microwave used some phantom powerand has now been put on a power bar.

So, it is definitely very interesting to see how much goes to waste inside your home when you have things plugged in and think that they are not using any energy whatsoever. Go to the library and get yourself one of these energy measuring devices because it will save yourself and your family a lot of money.
