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.

You just need to apply some science.

Back in the early 1900s, if you felt a bit sluggish you could reach for a beverage enhanced with radioactive elements to really add some pep to your step. It wouldn't be a healthy choice, though.
Koeberg power station, in Cape Town, is the only nuclear power station on the African continent. South Africa is considering a proposal to build more such power stations.
The argument put forward by Eskom that it can handle South Africa's controversial nuclear build programme is fundamentally flawed.
New technologies that can help us to meet climate change targets are struggling to see the light of day. Incentives need to be fixed, and carbon pricing is at the heart of the matter.
Australia’s LNG exports have driven domestic gas prices higher.

With gas prices high, coal-fired power has been increasing, which is bad news for carbon emissions.
Wind and solar power can be intermittent. Should our usage be too?
Christopher Pyne, Malcolm Turnbull and Steven Marshall have all spoken out on renewables in South Australia.
Storage is the issue politicians must deal with if we are to transition away from coal and gas based power generation.
South Africa is one of the top ten wine producing countries in the world.
It takes a lot of electricity to produce wine. If the industry wants to remain sustainable, it must place more emphasis on reducing energy use.
China’s State Grid Corporation was hoping to add a majority stake in Ausgrid to its growing global network.
Energy markets are increasingly global, with growing security issues. Disengaging is not the answer.
