WHO estimates 4.2 million people die prematurely each year due to air pollution, much of which comes from the burning of fossil fuels for energy.

Switching to renewables could cut the health impacts of air pollution from power generation as much as 80 percent by mid-century, experts said Tuesday.

Emissions from power generation account for around 40 percent of all energy-related carbon pollution, and demand for energy is predicted to rise globally for years to come. Writing in the journal Nature Communications, they then combined their calculations with human health indexes and analyses of the emission levels throughout a power unit's lifespan.

The PIK models predicted current energy trends would see six million years of life lost globally to air pollution by 2050. If the next three decades are dominated by renewables, that figure drops to about one million.He said all decarbonisation pathways the team studied showed significant health benefits, but the renewables-led approach showed by far the biggest health upside.The study also looked at the environmental and ecological impact of green energy generation heading towards mid-century.
