Companies could improve their profits 2-10% each year by saving energy, according to a world-first attempt to assess energy performance.
Video streaming services such as iPlayer need ‘green’ software, too.
Software is eating everything in this online, digital world. We need to design code that uses as little energy as possible.
When it comes to TV use energy, calling one household ‘average’ can be misleading.

People who watch a lot of TV consume a disproportionate amount of electricity so we should tailor energy efficiency incentive programs to these and other big energy users.

There's loads of advice out there on how to save energy. But how much of it is based on real scientific evidence?
Self-driving cars are way more energy efficient than your average vehicle – but that doesn't necessarily mean they'll reduce carbon emissions.
Homebuyers respond well to green features such as solar panels, rather than stats and figures.
Homebuyers want energy-efficient homes. The challenge is to present the relevant information in a way that taps into the typical house-hunter's mindset.
Supreme Court ruling allows consumers and businesses to make money by reducing power and other grid services.
An obscure Supreme Court ruling paves the way for people and businesses to earn money with distributed energy technologies.
Plugging in: more energy efficient cars are just one of the ways to improve energy productivity.

Sweating it out through hot summer nights? Here are some tips when you're looking for something to cool you down.
Change is coming for Australia’s energy sector. Time for our leaders to embrace it.
The key drivers for energy in the 21st century are managing climate change, shifting community concerns, and radical technology change.
Gas bill got you feeling grey? A reverse cycle air conditioner could save you money.
Heating your home using electricity is not just cheaper, it's more efficient and can be considered renewable.
Better fuel efficiency means more money, less emissions.
Vehicle efficiency isn't just about reducing emissions. It can also save us money, and reduce our heavy reliance on imported oil.
Graphene could have a radical influence on the future of energy storage.

Something is needed to give the stalwart lithium-ion battery a boost for our increasingly power hungry mobile devices.
Tasmanian hydro power had a boom couple of years when the carbon price was in place.
A year after the demise of the carbon tax, we might expect both coal and greenhouse emissions to have bounced back, at the expense of renewables like hydroelectricity. Sure enough, that's what happened.
Energy efficiency has driven the recent fall in electricity demand.
In June this year, forecasts revealed residential and business demand has risen for the first time in five years. The trend could be here to stay, according to a report released today from the Australia Institute.
While the higher gas mileage may lead people to drive a green car more often, its other attributes may be less appealing.

Some worry that efforts to reduce energy consumption by increasing fuel efficiency cause a so-called rebound effect that eats into the expected savings. We tested the theory.
Conventional forecasts have consistently overestimated energy use, leading to increased investment in energy infrastructure.

Electricity forecasts just 4 years ago predicted strong, uninterrupted growth in electricity demand. In reality, demand has fallen for the past four years. Why?
Lots of wind blowing – often at night when there’s little demand for power.
Smoothing out variable wind and solar is a growing problem. Instead of storing energy with batteries, utilities can adjust the power of millions of devices in buildings and homes.
Take that extra hour off work. Just don’t spend it burning coal or petrol.
Being time-poor makes it harder to be green, says a study which shows that people who work long hours are more likely to fall short on taking real action to address their environmental concerns.
Batteries to store excess solar power will be a game-changer. But energy-efficient appliances will mean you can use a smaller battery.

The unveiling of Tesla's Powerwall home battery has been hailed as a huge moment in renewable energy. But don't forget the other innovations that can help you use that stored power more efficiently.
