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.
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.
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?
Storage is the issue politicians must deal with if we are to transition away from coal and gas based power generation.
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.
Energy markets are increasingly global, with growing security issues. Disengaging is not the answer.
