Fuel energy density: What is it and why is it important?

Fuels like wood, diesel, and natural gas have shaped human energy history, driven by technological, economic, and environmental forces. Liquid fuels from oil, with their high mass and volumetric energy density, led to their supremacy in transportation. Shifts in fuel types also influence the devices that convert them into energy services.

Is the reserve-to-production ratio for fossil fuels a meaningful indicator?

The reserve-to-production (R/P) ratio calculates the lifespan of fossil fuel reserves based on production rates. In the U.S., regulatory frameworks affect reserve reporting, with oil R/P ratios declining from over 40:1 in the early 20th century to about 10:1 today. State-owned enterprises often inflate reserves, complicating future availability assessments.

Global anthropogenic sulfur dioxide emissions, 1750-2022

Sulfur dioxide (SO₂) is a major air pollutant produced from burning sulfur-containing fuels. It poses health risks, including respiratory issues and links to heart disease, while harming the environment by contributing to acid rain. Emissions have significantly decreased due to regulations and technology, but global reliance on fossil fuels continues to impact levels.

Underground natural gas storage in the United States

Natural gas demand in the U.S. varies seasonally, with higher consumption during colder months potentially causing price increases due to supply shortages. Underground storage, primarily in depleted reservoirs, salt caverns, and aquifers, helps balance supply and demand year-round. Storage levels drop significantly during colder winters, affecting overall availability.

Global natural gas flaring, 2012-2023

Crude oil and natural gas often coexist in reservoirs, leading to natural gas flaring when oil is extracted. This process not only wastes energy but also contributes significantly to global methane emissions. Despite initiatives like the Zero Routine Flaring by 2030, flaring volumes remain high, particularly in nine major countries responsible for the majority.
