Environmentalists and climate hawks are cheering, but many experts aren't excited about the state making rooftop solar panels mandatory on most new homes beginning in 2020.
Tesla is installing one of the world’s largest solar arrays at its Gigafactory 1 in Nevada.
Will the renewable energy transition end up creating yet more greenhouse emissions, as we ramp up the manufacture of wind turbines and solar cells? Not if their manufacture is itself powered by renewables.
Solar photovoltaics are now the world’s leading source of new electricity generation.

Solar photovoltaics and wind power are on track to supplant fossil-fuel-based electricity generation by the 2030s. The only thing holding back the renewable revolution is politics.
Grid-scale energy storage systems may make it easier to rely completely on renewable energy.
Saving power to use later lets consumers, businesses and utilities generate energy when it's cheap and deliver it when they need it most. There's not much of it today, but the industry is growing fast.
Looking through semitransparent cells – one day these could be big enough to make windows.
Solar windows would need to trap enough light to generate power, while letting through enough to keep buildings light. Thankfully, newly developed semitransparent cells offer to do just that.
Most of the growing number of jobs in the solar industry have more to do with maintaining and installing panels than manufacturing them.
The Trump administration can boost domestic solar panel manufacturing without slapping duties on all imports.
Managed in the right way, wind farms can actually help stabilise the grid, rather than disrupting it.

New modelling suggests that Australia could use renewable energy to hit its 2030 emissions reduction targets, without it costing any more overall than maintaining the status quo.
Transportation is the biggest contributor to greenhouse gases by sector. Converting the U.S. fleet to cleaner electric vehicles would likely take decades.

What if the world really got serious about meeting global climate goals? Doing the math on current emissions and the pace of energy transitions shows how quickly fossil fuels need to be phased out.
The new energy policy could potentially function to preserve black coal’s place in the energy mix.

The National Energy Guarantee proposal seems geared towards locking in the status quo rather than driving the much-needed energy transition.
The new policy could end up feeding demand for coal.

By rebranding coal as 'dispatchable', the government's National Energy Guarantee looks set to preserve demand for coal-fired power by giving it a new role – one it's not well equipped to fulfil.
Business as usual is not an option.
A new CSIRO roadmap outlines the options for oil and gas companies to keep pace with the clean energy transition, including solar-powered hydrogen fuel production.
Yes, but who’s directing energy policy?

We have learned a lot in the year since South Australia's lights went out, and have made some useful early reforms. But the energy sector and politicians need to chart a much steadier course in future.
Pumped hydro: all you really need is some reservoirs and a big hill.

Electricity storage is vital to the stability of a renewable energy grid. The world's favourite form of storage is pumped hydro – and researchers have located thousands of candidate sites.
The Victorian government is aiming to boost renewable energy to 40%.
Victoria's plan to legislate its own renewable energy target of 40% by 2025 shows how states are increasingly taking the energy policy reins away from the federal government.

Energy will become more and more integrated with artificial intelligence and the internet of things.
What a gas: one of Moreland’s new hydrogen-powered garbage trucks.
A local council goes for hydrogen. A state government goes for lithium and mirrors. They are taking punts on technology. What are the risks?
A report released this week by the Australian Council of Social Service has pointed out that many vulnerable households cannot access rooftop solar and efficient appliances, describing the issue as a serious…
Disruptive technology, Ming Dynasty-style.
In pulling out of the Paris climate agreement, Donald Trump has turned his back not just on the world but on the low-carbon economy. He should pay heed to a very apt lesson from China's history.
Women are making inroads in the solar industry, but still represent only about 25 percent of the U.S. solar work force.
Women are underrepresented in the energy sector at a time of rapid change and demand for new talent. Hiring more women could make energy companies more innovative and speed the shift to clean fuels.

These countries are well-positioned to lead the way from fossil fuels to low-carbon energy.
