Students from around the world calculated their class mean and standard deviations for their footprints and posted them on our world map.
Do you see differences across the globe? If so, why do you think those differences exist?
Did you use the calculator to try to reduce your footprint down to the average from a citizen of another country? What changes would you have to make to lower your footprint in this way? Are you going to try and take some of these actions in your daily life?

Electricity
Should we use less electricity?
using less electricity does mean fewer carbon emissions -- but if we use clean energy to make electricity (wind, solar, geothermal.... or despite it's other environmental negatives, hydropower and nuclear) then electricity use would have a very small footprint.
A Stanford research team has calculated that with current technology we can produce clean energy around the US and the world:
