How bad are fossil fuels actually

The document argues that the market price of fossil fuels fails to account for significant 'hidden costs' or externalities occurring during extraction, transport, and combustion. It details the severe health impacts of coal mining, such as black lung and cardiovascular disease, and the environmental degradation caused by mountaintop removal in Appalachia. The paper also examines the risks of oil and gas drilling, including methane leakage, water contamination from fracking, and catastrophic spills. Finally, it quantifies the economic burden of air pollution and global warming emissions, contrasting these with the lower impacts of renewable energy sources.

• Surface mining, specifically mountaintop removal in the Appalachia region, has devastated approximately 1.4 million acres of land and buried nearly 2,000 miles of biologically diverse headwater streams as of 2010.
• The public health and life cycle costs of coal surface mining between 1997 and 2005 were estimated at $74.6 billion annually, which represents about one-third of the average electricity rate for a typical US home.
• Hydraulic fracturing (fracking) involves massive water and chemical use; one study found that 25% of 353 tracked chemicals in fracking products cause cancer or other mutations, and roughly half damage critical bodily systems.
• Methane leakage from natural gas infrastructure is a significant climate driver; methane is 34 times more effective at trapping heat than carbon dioxide over 100 years, and losses must remain below 3.2% for natural gas plants to have lower lifecycle emissions than coal.
• Fossil fuel combustion is the primary driver of US global warming emissions, with 78% of 2014 emissions being energy-related, split between oil and other liquids (42%), coal (32%), and natural gas (27%).
• Air pollution from coal plants has immense economic and health costs; fine particle pollution in the US resulted in 13,200 deaths and 20,000 heart attacks in 2010, with total health costs exceeding $100 billion per year.
• Power plants contribute significantly to water stress in the US, with fossil fuel and nuclear plants withdrawing as much water as all farms; additionally, once-through cooling systems cause thermal pollution by releasing water up to 25°F hotter than the source.
• Coal waste management poses severe risks, with over a thousand slurry and ash sites in the US; at least 42% of these are unlined, allowing toxic heavy metals to leach into groundwater.
