Natural gas is the world’s third-largest energy source, and demand is still above 4,000 billion cubic metres a year, enough to supply about a quarter of global electricity and heat much of the world’s industry and homes. This category looks at where that gas goes, what it costs the climate, and how fast it can be replaced.
Gas became popular for good reasons. It was cheap, easy to pipe to customers and cleaner than coal at the chimney. It was also promoted as a “bridge fuel” that could cut pollution while renewables matured. That story is now hard to defend. Burning gas still produces greenhouse gas emissions, and about a fifth of energy-related carbon dioxide comes from it. Leaks of methane, a gas many times more potent than CO₂ over 20 years, make the footprint worse.
Here you’ll find analysis of gas use, emissions, subsidies, prices and the economics of switching. Our posts compare gas with solar, wind, batteries, heat pumps and electric appliances, with a focus on Australia, a major gas exporter and user. Whether you are a householder, investor or policy maker, these articles show why electrons are replacing gas faster than most forecasts expected.
