As discussed in the book, humanity must stop using all fossil fuels. One easy place for this to happen is through the elimination of coal-fired power plants. This article shows how easy (and economically rewarding) the elimination of coal-fired power plants could be:
The International Renewable Energy Agency (Irena) has found that up to 1,200 gigawatts of the world’s existing coal capacity could cost more to run than the cost of new utility-scale solar plants. If energy companies replaced only their most expensive coal plants with new solar power projects or onshore wind farms, totalling 500 GW globally, they could save up to $23bn (£18bn) every year and wipe out 5% of last year’s total global carbon emissions, according to Irena.
