Question: If everyone had solar panels would the earth lose all its human created carbon dioxide?

Dave is correct. Another thing to think about is: if everyone had enough solar panels to power all their electrical devices, what about all the carbon dioxide from cars, planes and trains? Or from burning gas to heat our homes? Or from concrete to build our homes? There’s a lot to think about to remove all human created CO2 and reach ‘Net Zero’! It will need solar working together with other renewables like wind and hydro power, and nuclear energy to cover the things that renewables can’t.
