Build power plants and energy storage facilities and intelligently connect them to high-voltage power lines to supply cities and industrial plants with electricity.
Buy gas, coal, and CO2 certificates as cheaply as possible for your thermal power plants. Or invest in renewable energy with wind, solar, and hydroelectric power plants. Then, however, you'll need to compensate for weather fluctuations with sufficient storage capacity.
Can you supply the entire world with electricity? And do so continuously without any power outages?
