As the urgency of the climate crisis grows, new analysis reveals that coal is no longer the cheapest way to power the global economy. The cost of clean energy has fallen so far that new renewables are now cheaper than new coal plants virtually everywhere, and there are specific financial strategies that utilities and policymakers can use to engineer a faster phaseout of coal in various regions of the world.

The rapidly declining costs of renewables push net annual savings to $105 billion in 2025. All this is before considering coal’s dire health, climate, and environmental impacts, or accounting for the social and environmental benefits of reducing pollutants. Currently, coal phaseout hasn’t kept pace with eroding economics.
