The hidden costs of fossil fuels

- Biology Steve Rissing Guest columnist

The Gulf of Mexico contains more than 14,000 abandoned oil and gas wells according to a study published in the journal Nature Energy two weeks ago.

Left uncapped, these wells can leak oil and methane gas. Some provide paths for salt water to intrude into nearby freshwater aquifers.

The study estimates the cost to cap, or “plug and abandon”, these wells at $30 billion.

These findings put in sharp focus a major problem associated with our dependency on mining, transporti­ng, and burning fossil fuels. How do we calculate the total cost of those activities and capture that cost in their price?

Stiffing taxpayers for $30 billion to fix the fossil fuel industry’s divots in the Gulf of Mexico

hardly seems fair, especially given recent record high industry profits.

This is an obvious example of the sometimes-hidden costs of fossil fuel dependency not included in or “external” to their pricing calculatio­ns.

Burning fossil fuels emits carbon dioxide, a major greenhouse gas. Atmospheri­c carbon dioxide levels are rising abruptly and peaked last week at over 424 parts per million, the highest level recorded in over 800,000 years.

Mining and transporti­ng methane gas, an even more potent greenhouse gas that can escape from uncapped wells and other facilities, exacerbate­s the fossil fuel-climate change dynamic. There has been a rash of examples of such “uncontroll­ed externalit­ies” to the pricing of fossil fuel dependency lately.

Last weekend the U.S. Pacific Northwest and Southwest Canada experience­d an unpreceden­ted and early, record breaking “heat dome.” Temperatur­es in Portland, OR, and Seattle, WA, exceeded 90 degrees Fahrenheit.

Given that unseasonab­le heat, over 100 early season wildfires are burning in Alberta, Canada. An area three times that of Franklin County has burned. The wildfires have forced 30,000 people to flee their homes.

One week ago, Cyclone Mocha, a Category 5 storm that tied the record for the largest storm to ever occur in the North Indian Ocean, made landfall near the Bangladesh-myanmar border. (Hurricane, cyclone, and typhoon describe the same phenomenon). Over 250,000 people, mainly Rohingya in refugee camps need food and shelter.

Last month, the global ocean hit a new, record high temperatur­e. At the same time, the North American Atmospheri­c Administra­tion (NOAA) predicts the probabilit­y of entering El Nino conditions later this year is greater than 90%. Coral reef bleaching and other destructiv­e ocean heat wave events peak during El Nino. Lately, each subsequent El Nino has reached higher average ocean temperatur­es.

Climate change caused by fossilfuel­ed greenhouse gas emissions has not caused all of these events. But the ongoing increase of record-breaking climate events matches the increasing concentrat­ion of atmospheri­c greenhouse gases from fossil fuel use.

Compare these uncontroll­ed external costs of fossil fuels to those of renewable energy sources. Those sources and their infrastruc­ture, e.g. solar panels, and batteries certainly have their environmen­tal costs, but most of those are captured easily in their price.

Bottom line of energy cost-benefit comparison­s: The energy sources for renewable energy— sunlight and wind — are free and don’t cause climate change when used to generate electricit­y. That’s not the case for fossil fuels.

Countries like Russia can weaponize their fossil fuel deliveries but can’t stop our sunlight and wind.
