In order to get to zero emissions by 2050, which is 10, 568 days from now, you need to replace 22 TW of energy generating capacity or 2.1 GW/day from now until 2050:
• One 2.1 gigawatt (GW, 109 watts) nuclear power plant each and every day until 2050, OR
• 3000 two-megawatt (MW, 106 watts) wind turbines each and every day until 2050 plus a 2.1 GW nuclear power plant every day and a half until 2050, assuming there’s not one turbine failure for any reason, OR
• 96 square miles (250 square kilometres) of solar panels each and every day until 2050 plus a 2.1 GW nuclear power plant every day and a half until 2050, assuming not one of the panels fails or is destroyed by hail or wind.
I sincerely hope that everyone can see that any of those alternatives are not just impossible. They are pie-in-the-sky, flying unicorns, bull-goose looney impossible.
