If you have checked out one of our Kill-a-Watt energy meters, please help us improve this program by taking a short survey.
If not, check one out next time you're at a San Jose Public Library. You can plug the device into any of your household appliances to see how much energy each one uses, and how much it costs you on your monthly utility bill. This is also a great way to find out how much energy your TV and microwave use even when you're not using them - a phenomenon called phantom load.
You can check out a Kill-a-Watt free of charge at any of our nineteen locations for three weeks, the same loan period as a book.
