The genius of the Paris climate agreement was getting major oil producing countries to agree to a target, but they still have widely different views of energy’s future.

Fifteen years ago electric power generation was the largest source of US greenhouse gas emissions. Now the power sector is leading the shift to a clean energy economy.
Ethiopia, Sudan, Egypt and their neighbours could deploy large-scale solar and wind farms, connected by a regionally integrated power grid.
Rare-earth metals are currently mined or recovered via e-waste recycling — methods with drawbacks including high cost, environmental damage, and risks to human safety. This is where we come in.
Australia must treble its emissions reduction targets and reach net-zero emissions by 2035. Without this and other radical global action, the chance to hold warming to well below 2°C will pass us by.
Earth’s floating solar power capacity has grown one-hundredfold in the last five years.
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.
Unless mining is done differently, rushing to bring copper mines into production could unleash unacceptable, catastrophic impacts.
Right now, the nation is almost entirely dependent on other countries for minerals that are used in everything from wind turbines to strike fighters and satellites.
The US electricity grid is actually five regional grids, and it’s hard to share power between them. A macrogrid could bridge the gaps, making electricity cheaper and more reliable.
Making biofuels from crops grown on land poses trade-offs between food and fuel. A new study looks offshore.
To increase renewable energy use, the Biden administration wants the US to go from seven offshore wind turbines today to enough to power 10 million homes within a decade.
Renewable energy sources won’t make a decisive impact to alleviate South Africa’s power shortage for at least five years.
Anthony Albanese will promise a Labor government would deliver a discount to cut the cost of electric cars and install community batteries, in initiatives costing $400 million over several years.
Britain’s electricity sector continues to decarbonise, but its capacity to store energy lags far behind.
What was a feature of power stations such as Yallourn has become a bug.
Green hydrogen produced using New Zealand’s mostly renewable electricity sounds like a great idea, but a high-tech smart rail and urban tram network is a more obvious and sustainable option.
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.
For an orderly transition from fossil fuels, Australia needs a carbon price to replace its hodgepodge of clumsy government interventions.
New social housing can provide a safe, secure and climate resilient home for tenants.
