The sheer number of Chinese-funded dams pose a substantial risk to biodiversity. And yet, environmental regulation of these projects has serious flaws.
How does flowing water make electricity? An engineer explains hydroelectric generation.
The mega dam in Jinja was meant to give Uganda energy independence, but this was constrained by Britain’s agricultural interests in Egypt.
New research shows how hydropower is linked to extinctions.
China is in the midst of a devastating heatwave and drought. This has thrown the nation into an electricity crisis. And China has doubled down on coal investments to meet demand.
A climate scientist looks at what works and some popular ideas that aren’t as cheap or effective as people hope.
Considering South Africa’s climatic advantage, the fraction of electricity generated from renewable energy technologies is low.
Stemming the water crisis in the western US will require cities and rural areas to work together to make water use on farms – the largest source of demand – more efficient.
The 2012-2015 power crisis was the most intense, protracted and severe in the history of Ghana.
Indonesia has a nature-based solution for when solar power isn’t being generated: its enormous potential for off-river pumped hydro energy storage.
Climate change is affecting hydropower in different ways across the country.
The Colorado River provides water and electricity to 40 million people in the western US, but falling water levels threaten both of those resources.
Data analysis suggests local activity will intensify the effects of global warming - so adapting means rethinking national development strategies
A team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.
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.
Addressing inefficiencies in Ghana’s electricity sector will reduce the need to price in distribution losses
In Australia and around the world, failures in flood warnings can have devastating effects. But ‘humanitarian engineering’ may have the answer.
A study points to one way to speed up adoption of innovations in clean energy technology – more flexibility among state regulators.
Thousands of dams across the US are aging and overdue for maintenance. Taking them down can revive rivers, restore fish runs and create new opportunities for tourism and outdoor activities.
