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.
Solar panels are still a rarity in WA’s lower-income areas.
Western Australia has huge amounts of sunshine and wind, yet only 7% of its energy comes from renewables. What's more, most households in the poorest suburbs are still locked out of the solar panel boom.
Eclipses are fun, but no one wants to be left in the dark by a blackout.
The solar eclipse offered electricity network operators a "live drill" in how to cope with fluctuating output from renewable energy. They passed with flying colours.
Solar PV outstripped coal as the leading source of new electricity generation worldwide last year.

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.
Getting your strata committee to agree to solar panels is tricky, but it can be done.
Apartment-dwellers risk being left behind in the rooftop solar boom. But some projects are showing how apartments can join the transition to a distributed renewable energy future.
If harnessed properly, the sun holds tremendous potential to provide sustainable energy for the earth.
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.
World Environment Day 2016 in Nairobi celebrated under solar-powered floodlights.
The UN Sustainable Energy initiative has set the goal of ensuring sustainable energy for all by 2030. However, the international community still can't overcome the problem of energy access.
Over a period in which the Australian economy saw around 600,000 additional people get jobs, employment in the renewables sector has been going backwards.

Estimates released by the Australian Bureau of Statistics suggest that the number of direct full-time equivalent jobs in renewable energy activities has continued to fall from its 2011-12 peak.
With the right mix, the grid can go fully renewable for the same cost and reliability as fossil fuels.
The Turnbull government is funding energy storage as a crucial missing piece of the electricity grid puzzle. Analysis suggests an affordable, fully renewable grid doesn't require any heroic assumptions.
Solar subsidies encouraged a massive take-up of solar panels in Australia.

The Australian Renewable Energy Agency has survived, amid a groundswell of domestic and overseas support. Its budget has been chopped, but here's how it can still drive the renewable energy revolution.
Connecting renewable energy across Australia will help generate reliable electricity.

Cuts to ARENA as part of the government's savings bill are short-term politics at its worst.
Australia has been a world leader in solar panel development.

An open letter from 190 solar energy researchers in defence of the Australian Renewable Energy Agency, which has funded world-leading research.
Africa has the best solar resource in the world.
Despite having some of the best solar radiation levels in the world, the diffusion of solar energy systems in Africa has been very low
The linchpin to Tesla’s proposed merger with SolarCity is the Gigafactory and whether it can lower costs and improve battery performance.
Critics don't think Tesla can sell enough home batteries to justify its acquisition of SolarCity, but what they're underestimating is the potential for innovation the Gigafactory brings.
Windbacks to solar subsidies may encourage larger systems.
