A combination of climate change, a strong El Niño and an insistence on works of enormous impact are contributing to an unprecedented and extremely urgent situation in the region
How does flowing water make electricity? An engineer explains hydroelectric generation.
To get to 82% renewables by decade’s end means storage - and that’s where we hope our new atlas of sites for pumped hydro storage can help
The mega dam in Jinja was meant to give Uganda energy independence, but this was constrained by Britain’s agricultural interests in Egypt.
Pumped hydro offers us large scale energy storage. If we do it carefully, we can make sure these dams don’t cause the damage of the past.
If South Africa fails to implement the 2019 Integrated Resource Plan, it will lead to the demise of Eskom as an energy producer as users turn to alternative electricity sources.
Climate change is affecting hydropower in different ways across the country.
Nigeria’s national electricity grid has collapsed more than 200 times since 2010, regularly resulting in widespread blackouts.
In an effort to save Lake Pedder from a hydro-electricity scheme, the world’s first political party with a foundation in environmental values was formed in Tasmania.
Diverting water to a hydroelectric dam might seem eco-friendly, but the devastating consequences to local ecosystems cannot be ignored.
The world hydropower industry has public relations work to do, if its global expansion is to be realised. But stringent oversight is urgently needed.
Dams built in an earlier age are suddenly vulnerable as the climate shifts.
Rather than considering the job done, Tasmania should seize opportunities including renewable energy, net-zero industrial exports and forest preservation.
Britain’s electricity sector continues to decarbonise, but its capacity to store energy lags far behind.
A study points to one way to speed up adoption of innovations in clean energy technology – more flexibility among state regulators.
Wind travels all over the world. Where does it come from, and why?
Sea levels are rising, while deltas are being starved of sediment by upstream dams.
A $12.7 billion investment in hydroelectricity has put Canada’s economic welfare and its moral credibility on the line.
When the Aral Sea dried up, it was called the “world’s worst environmental disaster”. We’re witnessing its equivalent in Africa.
Canada’s proposed new environmental assessment law is facing heated, if not necessarily well-informed, opposition. The real question is whether it goes far enough.
