Build power lines.
1. In terms of electricity, we can only build solar power stations at the beginning. One is enough. Later, when wind power becomes available, we will use wind power. If solar power is too useless, we can also use it later. Demolished.
2. Electricity can be transmitted through the building itself, so transmission lines should not be built in urban areas. After the city expands, they will be deleted when you plan the area.
