In a hungry world, using corn for fuel is a crime. If all usable rooftops were "solarized", NREI says that this would produce a quarter of our electrical needs. Thanks.
Rooftop solar is actually not as practical as it sounds, at least not for older houses. You need a roof that is structurally sound, you need relatively new roof shingles because it’s expensive to take solar down for a roof replacement. It’s a potential fire hazard if the installer does a poor job or there is an issue with any of the equipment. Your roof needs good orientation, and minimal transitions. Minimal pipe, vent, skylight penetrations. Minimal shading from trees and other nearby structures. You’re also looking at an electrical panel upgrade if you want to produce a decent amount of power.
@@triforcelink Granted a small percentage of roofs do not qualify. I used the term: "...usable rooftops...". This includes commercial buildings and new construction. I would also add parking lots and floating arrays. The storage of surplus renewable energy is a rapidly developing with decreasing price. The day will come that the combination of PV and battery storage will become quite common. Battery electric vehicles will tie into these systems. New methods such as load balancing and shifting will manage the interconnections.
Another Solar misconception is that if the whole world converts to solar power, or renewables persay it still would not solve the climate change problem. The current level of CO2 in the atmosphere will continue to contribute heavily, as well the transition period would last several decades as carbon emissions continue to contribute heavily as the offset may not ever happen when weighing in political, and cultural factors globally, not to mention the mining, manufacturing, construction, agriculture, militaries, and infrastructure, that will remain robust combustion fuel oriented. This is a race against time, as if these tipping points are occuring as some scientist already predict it may already be to late, as the signs of a changing climate is imminent. Nevertheless hey, we have to try. We have to do what we can, then hopefully the human race will find a way to maintain earths climate within healthy limits as for whats at stake, future generations, we dont want to get this thing wrong.

Also, the sun shines only during the day, and peak usage is in morning and evening. Battery storage at scale is still very expensive.

@@chrisconklin2981parking lots would be really good, shade AND power for your car.
