Clean energy could save hundreds of billions in health costs every year

In Paris late last year, the countries of the world pledged to reduce emissions to keep global warming “well below a 2 degree Celsius” rise in global average temperatures compared with preindustrial levels.

This would entail moving a large portion of U.S. power generation off fossil fuels and shifting the majority of our vehicles to electric power. That’s a tall order.

Most existing energy policies focus on the nearer term, and as yet there is no roadmap to achieve this 2°C limit – or even less aggressive targets for emissions cuts in the next 15 years.
