The biggest challenge of ditching fossil fuels may not be economic. Even some clean-power advocates acknowledge technology isn’t available yet to run power grids entirely on renewables without jeopardizing reliability.wow, ignoring your own data.
So the cost is irrelevant if you can't convert to 100% renewable energy.
Question: How long does CO2 molecule last in the atmosphere?
The lifetime in the air of CO2, the most significant man-made greenhouse gas, is probably the most difficult to determine, because there are several processes that remove carbon dioxide from the atmosphere. Between 65% and 80% of CO2 released into the air dissolves into the ocean over a period of 20–200 years.
Therefore, if all fossil fuels were 100% eliminated for any use, it would take up to 200 years to reduce the CO2 levels to whatever the natural level is without manmade emissions of CO2.
But, that should not be a reason not to convert to 100% renewable energy. Whatever the cost, if that is what the majority wants, go for it.
