Background: There is worldwide concern about the relationship between climate change and the use of fossil fuels. Many scientists believe that increased use of these fuels (in vehicles and other gas-powered equipment) has the potential to irreversibly damage our environment. In addition to the environmental concerns, supplies of fossil fuels are finite, and because they are non-renewable energy sources, we will eventually need alternatives. New developments in batteries and other energy storage devices are being explored to help deal with these issues. Electrochemical processes are at the heart of these new technologies.

Situation: Two countries used different fuels as power sources for their activities. Alsacia used fossil fuels, while Lorena devised more advanced energy storage devices, therefore relying on electricity.
