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.
The long view: Australia is bidding to boost energy productivity by 40% by 2030, but other countries are already doing more.
Australia's federal government wants to boost 'energy productivity' by 40% by 2030. A good idea, but the plan needs to cut energy use, not just deliver more economic bang for the energy buck.

Unlike many countries, Australia does not have mandatory greenhouse emissions standards for cars - meaning that manufacturers are free to sell their least efficient, most polluting vehicles here.
Money spent on helping consumers reduce demand means less money spent on substations and other infrastructure.
Incentives for cutting peak power demand are cheaper than building ever more infrastructure and sending power bills ever higher. The industry has a chance to embrace this new approach - but will it?
Switching to alternative energy sources, such as renewables, and using more electric cars could double Australia’s energy productivity.

A new report shows Australia can and should double its energy productivity, increasing economic productivity while reducing greenhouse gas emissions.
Wind energy will be an important part of the world’s energy future - but it won’t be enough to feed growing demand.
Peak fossil fuel and action on climate change will mean we have less energy available to power the future.
Rising gas prices, driven by the development of Queensland’s exports, could end up driving domestic customers away.

Gas developers have been ominously warning of impending gas shortages in New South Wales, with official forecasts from planning authorities pointing to steady or rising demand. Yet our analysis suggests…
Monitoring energy is first step to saving energy.
The message from the yearly CES consumer electronics extravaganza was clear: the list of gadgets that can be connected to the “internet of things” is growing rapidly. These smart-home technologies have…
Cooking on gas could be unpalatable when the bill arrives.
During Melbourne’s recent spell of hot weather, my air conditioner got a workout after a long hiatus. Technically it’s a split system that also could have been used during winter, but like many Melbourne…
Motorists in the United States and elsewhere have been treated to low prices. Whether they will bounce back is another question.
Late in 2014, we saw iron ore and coal prices fall. Now we are seeing oil prices tumble, dipping to less than US$50 a barrel, half the price of a year ago. In all cases, these price collapses reflect the…
