Diatoms - like those seen under a microscope here - can teach us a lot about harvesting light.
Diatoms' tricks may offer new insights that keep solar cell energy running efficiently and robustly throughout their processes.
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.
If Caribbean governments can’t afford to rebuild their islands, maybe big tech firms can?
Tesla, China and Richard Branson are among those offering to help Caribbean nations rebuild – and do so in a greener, more resilient way – after the devastating 2017 hurricane season.
A solar and battery-powered microgrid got San Juan’s Children’s Hospital quickly back online after Hurricane Maria.
Yes, Puerto Rico and any other storm-vulnerable location could benefit from on-site solar and battery backup, but it's unrealistic to say these microgrids are enough to power the island.
The price of new-build renewable energy is expected to fall significantly relative to new-build coal energy in coming years.

Amid news that solar power capacity will outstrip nuclear by 2018, what do those assertions really mean?
The imposition of steep duties on imported solar panel components could jeopardize thousands of jobs in the industry.
A trade spat could jack up the cost of going solar, killing jobs and obstructing efforts to do something about climate change.

Solar PV and wind energy have overtaken coal as the leading sources of new electricity generation worldwide, with falling prices and new storage technologies making clean energy ever more attainable.
The UK is about to miss an opportunity if it tries to take on the giants of the lithium-ion battery industry.
You may agree the U.S. should move to renewables, but how quickly can we do it and how?
How fast can the US transition to clean energy and with what energy sources? Here's why an impassioned debate among energy wonks matters to the rest of us.

India, the world's fourth-largest carbon emitter, long resisted calls to fight climate change. Now it is investing heavily in clean energy and expects to meet its Paris climate accord target early.
Lessons from the Lone Star State: A surge in wind power on the Texas grid didn’t cause reliability problems (and brought down electricity prices) because regulators improved the efficiency of wholesale electricity markets.

Energy Secretary Rick Perry wants to know if wind and solar are compromising the reliability of the grid and hurting coal power. The answer lies in his home state of Texas.
Solar provides tremendous opportunities for emerging entrepreneurs.
Africa's energy potential remains under-exploited, the energy entrepreneur is well-positioned to take advantage of the opportunities presented by the energy sector.
Western Australia’s largest private solar array covers the roof of this food distribution centre in Perth’s south.
Despite its name, the National Electricity Market doesn't reach WA. But those charged with guiding the eastern states' energy transition should look west once in a while.

Scientists investigating an underwater mountain have found lots of tellurium, a mineral used in some solar panels.
To manage renewable energy efficiently, all weather variation need to be taken into account.
Relying less on fossil fuels is one of the key challenges of energy transition, and taking weather variations into account can help increase the overall efficiency of a renewable-energy system.
Do androids smell electric roses?
Peak energy demand sometimes occurs when there’s no wind.
Here are some short- and medium-term strategies for transitioning to renewable, reliable and affordable energy in South Australia.
Watt a good idea.
Many believe we can stabilise the power supply by asking customers to help - but there's a problem.
