ELI5: Explain Like I'm 5

European super grid

A European Super Grid is a system of power lines that connect countries in Europe together. These power lines make it possible for electricity to move from one country to another, like sharing a big power cord. This means that electricity from one country can be used in another country! It also means that after electricity is used in one country, it can be sent somewhere else to be used again. This helps make sure electricity does not run out and helps lower costs for everyone.
