Chemicals found in food and solar cell technology have an interesting history – as my own research shows.
Weak regulation and a lack of mandatory inspections have increased fire risks for the one in four homes with rooftop PV panels. Here's what we need to do to be safer.

Halide perovskites are cheap, versatile and remarkably efficient as both solar cells and light emitters.

Solar cells make electricity directly from sunlight, but how do they do it?
Kids are more engaged when they are actively involved in their learning, rather than learning through more passive modes such as listening or reading.
Kids are more engaged when they're actively involved in their learning. Here's how three schools are teaching kids about sustainability by being sustainable themselves.

Climate journalism can play an important role in painting the picture of a post-carbon economy. It should start by encouraging collective action and a sense of empowerment for everyday people.

Australia is in the midst of a solar energy boom, yet it is lagging behind other countries when it comes to 'building-integrated photovoltaics' - solar cells built into the very fabric of buildings.
Consumers want to embrace sustainability, but still need some guidance.
There's a buzz around sustainability, but consumers still struggle to develop new habits. Here's how to change that.
Rooftop solar has boomed, but soalr panels only last about 20 years. What happens to the waste?
Australia urgently needs to prepare for a coming tsunami of solar panel and battery waste.
The takeup of rooftop solar was much more rapid and widespread than many policymakers predicted.

Australia's consumer watchdog has concluded that rooftop solar incentives have distorted the market unfairly for those who cannot afford solar panels, and has recommended the scheme ends ten years early.
The latest research suggests that in Australia, rooftop solar photovoltaics are more likely to be adopted by middle-class households.
Households that are most likely to go solar are those that can afford solar panels, but aren't so rich that they don't have to worry about their electricity bill at all, says a survey of 8,000 homes.

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.
Could this monitor and window be combined with a solar panel?
Organic semiconductors could make possible energy-generating windows that double as movie screens or computer displays.
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.
Now that panel costs in U.S. will go up, will reflectors make a comeback?
Joshua M. Pearce
Raising the cost of solar panels coming to the US could rekindle interest in a simple but potentially significant technology: solar reflectors.
Blockchain technologies could help homeowners sell their green electricity to their neighbours.
Blockchain technology could be applied to our energy grids to make them smarter, and turn energy consumers into producers.
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.
The potential clean energy sources are all around Sydney, just waiting to be harnessed.

Sun, wind, waste biomass, geothermal, tides and waves: all these energy sources in Sydney's backyard add up to a zero-carbon energy solution for the city.
Many homes in remote Indigenous communities rely on wood or diesel for heating.

More than 200 remote communities in Canada rely on diesel fuel for energy. Cleaner options could fuel a better quality of life.
