Energy mix - Our World in Data

Natural gas has, for decades, lagged behind coal and oil as an energy source. But today its consumption is growing rapidly – often as a replacement for coal in the energy mix. Gas is a major provider of electricity production, and a key source of heat. This interactive map shows the share of primary energy that comes from gas across the world.
