Nuclear power in the US has steadily contributed 19% of electricity since 1990, mainly through uprates. These uprates, approved by the NRC, have boosted capacity by 24,080 MWt or 8030 MWe, equivalent ...

The historical energy transitions showcased significant advancements in energy converters, improving power output and efficiency, which spurred population and economic growth. Roger Fouquet’s analysis...

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 em...

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 declin...

In 1898, H. Riall Sankey developed a diagram illustrating steam engine efficiency, leading to the widespread use of Sankey diagrams for visualizing energy flows in various systems. They effectively display energy extraction, transformation, consumption, and losses while mapping the roles of primary and secondary energy sources across different usage sectors.

Nuclear power plants have a nameplate capacity of about 390 gigawatts and supply 10% of the world’s electricity. The United States, Russia, France, Japan, South Korea, and China account for 71% of glo...

Carbon monoxide (CO) is a toxic, colorless gas from incomplete combustion of fuels, leading to potential health hazards like headaches and confusion. Residential sources produce significant CO emissions, impacting 2.4 billion people reliant on biomass. Globally, emissions peaked in 1989, but have since declined due to regulations and technological advancements in combustion efficiency.

NOx, comprising nitric oxide and nitrogen dioxide, significantly impacts air pollution and health, causing respiratory issues and contributing to harmful pollutants. Mainly emitted from transportation and industrial activities, NOx levels vary globally. Efforts to reduce emissions include regulatory policies and technology advancements, along with a shift towards cleaner energy sources.

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.

Low-level radioactive nuclear waste (LLW) is produced by various commercial operations and the U.S. Department of Energy. It includes contaminated materials like clothes, tools, and medical supplies. LLW is typically stored on-site until it decays or is shipped to disposal sites, regulated under the Low-Level Radioactive Waste Policy Act of 1980.

Fossil fuels serve non-energy purposes, comprising about eight percent of global consumption. Their use has doubled since 1990, driven by demand for products like plastics and chemicals. Non-energy uses include asphalt, petrochemical feedstocks, lubricants, and fertilizers, contributing to rising carbon dioxide emissions, a concern for climate change mitigation.

A peak shaving facility is an energy system that balances fuel demand fluctuations, particularly for natural gas during peak usage times. It stores liquefied natural gas (LNG) at low demand and releas...
