There's a wealth of climate policies to choose from this election – but what will they do electricity prices?
The closure of Port Augusta’s Northern Power Plant marks the end of coal-fired generation in South Australia.
Closure of the state's last coal power station will leave a potential gap in the electricity supply.
Acid drainage from surface coal mining site, North Lima, Ohio.
As coal energy loses market share, major U.S. coal companies are filing for bankruptcy. One multi-billion-dollar question: will taxpayers be forced to pay for cleaning up abandoned mines?
Building more renewable energy will be part of the effort to decarbonise energy systems.
We have the technology to phase out fossil fuels, but it will take more than that.

Coal seam gas may not be responsible for a flaming river in Queensland, but it still raises uncomfortable questions.
Despite the benefits of going renewable, it may be harder to get there than we thought.

Phasing out fossils fuels would go a long way to stopping dangerous climate change – but it might be harder than we thought.
Labor has promised 50% of electricity will come from renewable sources by 2050, but has left the detail for after the election.

Labor's detailed climate policy is ambitious, but it remains to be seen if it will capture the voters.
An LNG tanker leaves Gladstone, Queensland. Gas development is one of the drivers behind Australia’s increasing emissions and electricity demand.
Over the past year Australia's greenhouse gas emissions from electricity rose 2.7%.
Is the coal train leaving town?
We hear a lot about how essential coal and other mineral exports are for Australia. Is it true? Only for a relatively small section of the population.
The era of coal is coming to an end.
Peabody, the world's largest private coal company, has filed for bankruptcy, symbolising the world's swing away from coal.
China’s coal use has gone down two years in a row – or has it?
It's a transition the rest of the world is watching: How can we know whether coal use in China – the world's largest emitter – is going up or down?
Ministers considering new coal mines need to take a step back and look at the bigger picture.

The granting of a mining lease to the Carmichael coal project, despite the huge potential greenhouse emissions, shows that ministers need to consider the wider consequences of their approvals.
A river flows into the Indian Ocean along South Africa’s Transkei coast, where residents are resisting a titanium mining project.
South Africans living in communities along the country's east coast are engaged in intensive protests against mining companies, despite rising danger.
Fife no more.
Longannet, the last coal-fired power plant in Scotland, has closed. It might be good news for climate change, but it also signals major problems ahead.
Graphite can be converted into synthetic diamonds used in manufacturing.
Australia needs to move beyond mining graphite and invest in processes that convert it into synthetic diamonds and use it to create carbon fibres.

Two years after Morwell was blanketed in smoke from the Hazelwood fire, environmental charges have been laid against the mine's operators. But the process should be more open and democratic - and quicker.
South Africa has made promises to decarbonise but is hugely reliable on coal - so this is difficult.
The process of decarbonisation is a complex one for South Africa, as most its power supply comes from coal.
An open-cut coal mine in the Hunter Valley.
Methane is a stronger greenhouse gas than carbon dioxide, and Australia's coal mines are a major source.
Renewables could be a better answer to India’s power problems.
A new analysis suggests that, all things considered, renewables are actually better than coal at lifting India's energy-poor out of poverty.
The southern black-throated finch could be brought to the brink by coal-mining developments.
More than half of the remaining habitat for Queensland's southern black-throated finches is potentially subject to mining development. If these mines go ahead, it will be bad news for these birds.
