Australia could be getting half of its electricity from renewable energy by 2025, even without government subsidies for new wind and solar projects, according to a new analysis of energy industry trends.
Remember, a belt-and-braces power grid doesn’t come cheap.

Sections of the media have talked up the prospects of future power outages, even though the electricity market operator predicts that Australia's stringent reliability standards will still be met.
The government is now firmly focused on lowering household power bills.

Fifteen years after the Northeast Blackout of 2003 cut power to 50 million people in the US and Canada, experts explain that many threats to the electricity grid remain.
The high-voltage lines carrying electricity across the U.S. aren’t the only potential targets.
Power utilities' cybersecurity practices may be effective, but need to evolve over time. And all companies operating elements of the grid – even the small ones – should step up.
Who’s in control of what’s flowing in these wires?

Experts explain the task of securing the electrical grid against cyberattacks, and discuss potential solutions and the risk of failure.
As the name suggests, Windy Hill near Cairns gets its fair share of power-generating weather.

There are calls from the backbench and elsewhere for the federal government to safeguard the future of coal. But do those calls make economic sense? A look at Queensland's energy landscape suggests not.

Generating less electricity with fossil fuels could help save lives.
Solar lowers prices and shifts when daily peak demand hours are.
Large-scale solar and wind tend to push energy prices down, which sounds great as a consumer. But that makes keeping the grid in constant balance harder.
Josh Frydenberg met with state energy ministers in Melbourne the latest round of discussions over the National Energy Guarantee.

The federal government is confident that states will sign up to the National Energy Guarantee, with a final decision now timetabled for August.
Is the long journey towards a bipartisan emissions policy nearing its end?
State energy ministers meet this week to discuss the National Energy Guarantee. While the policy has been criticised as too modest, it would put us light years ahead of the previous climate policy paralysis.

Lowering your carbon footprint by living off-grid is a sustainability dream. But how possible is it using current technology?
More blue sky thinking could help the grid get even smarter.

'Virtual power plants' offer extra power to the grid by tweaking the operation of batteries and appliances right across the network. But even this might be too blunt a tool for our future energy needs.
Keeping the lights on has always been a stormy issue in South Australia.

Two decades ago, the then SA premier, John Olsen, defied a campaign promise and announced plans to privatise the state's electricity industry. It's been a high-voltage issue ever since.
Solar and wind compete with coal power plants when it comes to energy storage systems.

Energy storage, such as big batteries, on the power grid is generally seen as 'green' technology but the reality is more complicated, an analysis finds.
Bill Shorten said he had become increasingly sceptical of Adani in recent months.
Bill Shorten has taken a further step toward opposing the proposed Queensland Adani coal mine.
There are ways we can stay cool in a heat wave without blasting air con at peak times.

Today, we're asking why some of the most disadvantaged parts of our cities cop the worst of a heatwave and how you -- yes, you! -- can do your bit to reduce the risk of a summer time blackout.
The storm clouds have been gathering over energy policy for a decade or more.

The Long Read: Most Australians' power bills have been rising for a decade. There are many reasons why, but the common thread is a lack of government willingness to get to grips with crucial policy problems.
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.
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.
