With the development of cities, energy becomes more and more important.

In Power On!, players should create power plants to supply energy for every city efficiently. There are four kind of power plants players can select: coal-fired, natural gas, nuclear and renewable-energy power plants. Each kind of power plants has its pros and cons. As the game end, player who obtain the most points would win the game.

Notice that when player use coal-fired or natural gas power plants to produce energy, he/she have to pile the "CO2 emission" token and make "carbon tower", thus "carbon tower" will be getting higher and higher. If carbon tower is so high that it collapses, players would pay the price.
