Keeping things cold wastes a massive amount of energy. What if this could be harnessed?
South Australia has the most wind energy in the country.

The South Australian and federal governments' energy feud reached a peak this week, but just who is responsible?
No matter how hard we dig, the Earth’s resources are ultimately finite.

Even supposedly "green" technologies such as renewable energy require materials, land and solar exposure and cannot grow indefinitely on this planet.
Why can’t we see the spaces?
The reason you feel things as solid is all to do with electrons.
Pro-Trump supporters in Manhattan. The new US president appeals to many Americans marginalised by globalisation.
The world needs an alternative system, measuring economic value in face of the dissatisfaction that brought Donald Trump to the White House.
Prime Minister Malcolm Turnbull spoke about clean coal at his National Press Club address.
In his speech this week to the National Press Club, Turnbull initiated a genuine “game-changer” in the debate about power generation in this country. It is instructive to focus explicitly on what he said…
The threat of the closure of Arrium’s steelworks in the SA town of Whyalla is just one of many that could disrupt the state’s economy.
South Australia is facing a whole range of social and economic problems that are forming the perfect storm.
Time for another ‘reset’?
As Trump explores warmer ties to Russia, he'd be wise to brush up on the history of past resets and the role the oil industry played in each one. The results weren’t good.
Will 2017 be the year Australia sorts out its energy policy?

The goals are clear: clean, cheap, reliable energy. But no-one can agree how we get there.

Leaders are worried US leadership on global issues like climate change will be diminished under President Trump. Experts explain why China is ready to lead, and how that could be a good thing.
Malawi is a country that’s particularly vulnerable to the impact of drought and flood.
Understanding the connections between basic food demands and accessibility to water and energy is important when it comes to climate change and its impact on agriculture and livelihoods.
Obama has prioritized development of wind and solar in a number of ways, including installation on military bases.

The Trump administration has the tools to slow the momentum Obama started on clean energy. Countering Trump are global market forces and state-level action.
The superheated plasma inside the fusion reactor is twisted by magnetic fields.

Fusion power, if it works, offers vast amounts of clean energy and almost zero carbon emissions. A new experimental fusion reactor has come online, and it uses a curious twisted stellarator design.
Australia’s average house size has more than doubled since 1950.

Bigger houses take more energy to build them, and use more energy.
Are OPEC’s cuts all smoke?

To see why, one must only consider the core economic principle of supply and demand.
Very powerful, try to avoid.
Lightning strikes are powerful – but we haven't had solid estimates of their energy until now. Researchers turned to the hollow stone tubes they create by vaporizing sand for more precise calculations.

Fusion development takes time. It cannot be developed in miniature and then be simply scaled up. But we must work now, to make it possible to meet humanity's need for abundant, clean energy.
The recently updated Integrated Resource Plan calls for significant investment in South Africa's power supply. But can the country afford it?
Eskom power lines. South Africa’s power utility may be in a much weaker financial position than generally appreciated.
A closer look into the latest financial numbers of South Africa's state power utility, Eskom, suggest that it may be in a more vulnerable position than appreciated.
South African consumers are paying far too much for petrochemicals products.
Raging debates about the state of South Africa's energy industry have missed one critical area, the role of transport fuels and base chemicals.
