Houses, merchantile, and manufacturing should be located on hillsides and in barren soil regions. Solar photovoltaic electricity generated directly from the sun produces zero emmissions. It's photosynthesis, very like the way trees and plants are activated by sunlight to grow. Batteries are somewhat polluting to produce and must be safely handled to store the electric if you are not simply putting perfect sine wave AC out to the grid utility or to your house or business.
Every battery is rechargable and recyclable.
