India and China are the cheapest places to install rooftop solar, while the US, Japan and the UK are the most expensive.
Four years after Hurricane Maria wreaked havoc on Puerto Rico, federal money to rebuild its electricity system is finally about to flow. But it may not deliver what islanders want.
President Biden’s proposed solar power expansion would cost $350 billion in federal support over the coming decade. An energy expert explains where that money would come from and who it would help.
The process of manufacturing gallium-doped solar panels was under a patent until last year. It’s only now that this method has started to pick up steam.
How much energy does the internet use, and - given recent technological advances - could it ever run on renewable energy alone?
More than six in ten Australians – 63% – support a ban on new coal mines opening in Australia, according to the Lowy Institute’s Climate Poll 2021.
As global oil consumption drops, oil companies are pivoting to petrochemicals, and could crowd out bio-based alternatives.
Scientists are working on ways to make lots of energy by converting matter into energy. The trick is keeping the process under control. One possibility is nuclear fusion – the Sun’s power source.
Installing solar panels over California’s 4,000 miles of canals could generate less expensive, renewable energy, save water, fight climate change – and offer a solution for the thirsty American West.
Technology innovation is one of the Biden administration’s most powerful tools for accelerating progress on climate change. Recent successes in renewable energy and batteries show how this can work.
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.
New social housing can provide a safe, secure and climate resilient home for tenants.
In a bid to ditch fossil fuels, some countries are considering carpeting deserts with solar panels.
Solar power doesn’t have to be just for the wealthy anymore. With the right kind of financial incentives, households at all income levels can benefit from affordable clean energy.
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.
Changes to the way houses and other buildings are constructed could lower energy use and greenhouse gas emissions.
How solar power stations in orbit could become a reality in the coming decades.
Many Asian nations are shunning fossil fuels, presenting a huge opportunity for Australia’s renewables sector. And one massive project has stepped up to the plate.
