While energy conservation is a big social issue, individual actions have a big impact. Here's how to save energy in your home.
1) Turn off the lights
Most people are doing this already, but it's worth mentioning: turning off lights and lamps when you aren't using them is the easiest way to save some energy. If you're gone from the house for more than an hour, go ahead and turn off your lights before you leave.
2) Use power strips
Leaving the computer on all day or running the TV when you're not watching? Plug those devices into a power strip, and turn it off when you're not using them. Almost all electronics continue to use energy when they're plugged in, even if they aren't turned on. To save even more energy, unplug your cell phone charger when you're not using it, chargers use electricity while they're plugged in even if there's no phone attached.
