To provide the power to mines and synths you need the huge solar power plants. The more stations built, the more of the surface is covered with solar panels which convert light energy into electricity. Solar power plants are the basis for the energy supply of the planet. The planet far from the sun produces less energy. You can increase energy production through the development of the energy technologies.
