Natural gas leading source of EU's power emissions

Gas power plants overtook lignite coal plants in 2020 to become the European Union's largest single source of emissions from electricity, an analysis of the bloc's Emissions Trading Scheme showed Friday.

'Agricomb' measures multiple gas emissions from... cows

After the optical frequency comb made its debut as a ruler for light, spinoffs followed, including the astrocomb to measure starlight and a radar-like comb system to detect natural gas leaks. And now, researchers have unveiled ...

Natural variations help resolve a climate puzzle

New research shows that naturally occurring climate variations help to explain a long-standing difference between climate models and satellite observations of global warming.

Natural gas

Natural gas is a gas consisting primarily of methane. It is found associated with fossil fuels, in coal beds, as methane clathrates, and is created by methanogenic organisms in marshes, bogs, and landfills. It is an important fuel source, a major feedstock for fertilizers, and a potent greenhouse gas.

Natural gas is often informally referred to as simply gas, especially when compared to other energy sources such as electricity. Before natural gas can be used as a fuel, it must undergo extensive processing to remove almost all materials other than methane. The by-products of that processing include ethane, propane, butanes, pentanes and higher molecular weight hydrocarbons, elemental sulfur, and sometimes helium and nitrogen.
