Even supposedly “green” technologies such as renewable energy require materials, land and solar exposure and cannot grow indefinitely on this planet.

The reason you feel things as solid is all to do with electrons.
The world needs an alternative system, measuring economic value in face of the dissatisfaction that brought Donald Trump to the White House.
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…
South Australia is facing a whole range of social and economic problems that are forming the perfect storm.
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.
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.
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.
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.
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.
Bigger houses take more energy to build them, and use more energy.
To see why, one must only consider the core economic principle of supply and demand.
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?
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.
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.
