Johannesburg occasionally smells like rotten eggs. The wind brings the smell from the east or the southeast, where most industries are located.
To improve air quality, a combination of efforts is needed including reducing Eskom’s emissions, investing in cleaner sources of energy, and reducing emissions.
Major research found Australia must keep 95% of coal in the ground to limit global warming. With a little political will, this would be easy to do.
Major coal generators say the proposal will help shore up energy supplies. But opponents say it will pay coal plants for simply existing and delay the clean energy transition.
New research found power stations in the Latrobe Valley emit around 10 times more mercury than power stations in the Hunter Valley. The stark difference has a lot to do with regulations.
Electricity emissions can be cut to net-zero while keeping the lights on and prices down. But achieving that quickly means keeping gas around, for now.
What was a feature of power stations such as Yallourn has become a bug.
Yallourn power station, Australia’s oldest and dirtiest coal plant, will close four years ahead of schedule. Without a national policy, coal workers are left dangerously exposed.
Plus new research on why China is closing down coal-fired power stations. Listen to episode 3 of The Conversation Weekly.
The end of coal-fired generation in Australia is inevitable. But the federal government can do more to ensure an orderly transition to renewables – avoiding price spikes and supporting workers.
If Canada began to reduce its greenhouse gas emissions by about four per cent per year, we could still meet our 2030 climate targets.
While much of the world moves towards zero-carbon economies, a NSW mega-plan for new renewables may set up the state as an energy superpower.
Emissions from Australia’s electricity sector have dropped markedly during the pandemic.
But a recession could cloud the renewables outlook.
It’s more freshwater than what the population of the Greater Sydney region uses, but finding this out wasn’t easy.
The benefits of gas-fired power are badly overstated, and will take Australia further in the wrong direction on climate change.
After a decade of rising electricity bills, prices are projected to fall thanks to new renewable generation.
We have quantified the effects of twelve power station closures in five states. Local unemployment shoots up and comes down only slowly.
Summer is here and the chance of blackouts is higher than normal. But the cause is unlikely to be the power station. The problem is usually much closer to home – in the local poles and wires.
South Australia’s energy prices have gone up as more renewables entered the market – but prices would have gone up even more without them.
The Labor Party’s newly announced energy policy could finally set Australia’s electricity sector on the path to a renewables-driven future. But policies are still needed to cut emissions elsewhere.
