About This Database

The first step towards energy efficiency or sizing your renewable energy system is in understanding your power loads. Power loads tell us how much power any appliance uses and AltE has long been working towards proving a real, comprehensive tool for researching and calculating the loads of actual appliances.

To that end, everyone at AltE has pitched in and we've been cataloging products and appliances in our own lives to add to our Kill A Watt database!

Now, we're taking this to the next level - opening the database up to our community to encourage everyone to enter their readings from Kill A Watt meters and similar devices to provide better data for everyone!
