Most people can easily quote the price of gasoline or how much they pay for their power bills at home. But what’s the cost of energy production and consumption on health?

“Hidden Costs of Energy: Unpriced Consequences of Energy Production and Use,” a new report from the National Research Council, a branch of the National Academies, tries to put a dollar figure on what economists call externalities.

The study, however, comes with a major caveat: it did not look at the impact of energy on climate change and ecosystems, or at rising food prices and the risks to national security.

Still, the report, which was requested by Congress in 2005, estimated that the hidden cost of energy on human health was $120 billion in 2005, the last year for which full data was available.

Unsurprisingly, the biggest contributors to these extra costs were coal-fired power plants, which generate half of the nation’s power but which also accounted for $62 billion in hidden damages associated with the emissions of pollutants like sulfur dioxide and nitrogen oxide, and particulate matter like soot or fine dust.

The report also found that in 2005 the vehicle sector produced $56 billion in health and other non-climate-change damages, with $36 billion from light-duty vehicles and $20 billion from heavy-duty vehicles.

“Because these effects are not reflected in energy prices, government, businesses and consumers may not realize the full impact of their choices,” the report said.
