In this village we have a power station that is powered by the renewable energy obtained from the City of Energy. The problem is that we can’t get the electrical installation to supply electricity to all houses … We need you to look and verify that the problem can be solved. You may need to connect and disconnect some cables, but don’t worry, we fully trust you!

There is another small task you have to do: Check energy use. In this village, a lot of electricity is wasted due to home appliances that are always plugged in and consuming electricity even when they are off. 

Are you ready to help us out and show us everything you know?
