- How much power does each appliance use in watts?
- How much does each appliance cost to use in dollars?

The types of appliances are occasionally random (aquarium? popcorn popper?) and a little role-biased (a curling iron but no electric shaver? kitchen appliances but no power tools?), but the tool is still useful for exploring and discussing our energy use at home, and it's fun to browse around.
When using this, remind yourself and your students that, while 20% of energy use "is residential," that means 80% belongs to business and industry, and while we can make different personal choices to decrease our energy use, it's also important that we work toward changing the systems to become more efficient and sustainable.
