Summary
Australia’s report card on reducing its greenhouse gas emissions is not exactly glowing, but there are ample opportunities to get it on track during this period of rapid change in the energy sector. Greater use of renewable electricity sources like wind and solar are playing a large part in reducing emissions, and gas can also lift its game.
Gas provides nearly one quarter of Australia’s total energy supply. Around 130,000 commercial businesses rely on gas, and it delivers 44% of Australia’s household energy to more than 6.5 million homes which use natural gas for hot water, domestic heating, or cooking.
Gas has lower greenhouse emissions than most other fuels, and the gas used in power generation has about half the emissions of the current electricity grid.
Even so, natural gas can do more to help Australia meet its carbon-reduction targets.
An industry document released last year, Gas Vision 2050, explains how new technologies such as biomethane and hydrogen can make that happen, by replacing conventional natural gas with low-emission alternative fuels.
