The world’s oceans cover more than 70% of Earth’s surface. They’re filled with currents, some much stronger than the fastest flowing large rivers. These currents can be harnessed as clean, marine renewable energy. Marine energy is much more predictable and reliable than many other forms of renewable energy because unlike sun and wind, which regularly … Continue reading Ocean currents can be converted to electrical power using turbines

The diseconomies of scale: study
Big power plants are more likely to face cost overruns than smaller plants, according to a new study by the Boston University Institute for Global Sustainability.The researchers found that the average power plant project costs 40% more to build than expected and misses its target completion date by nearly two years. In an article on the … Continue reading The diseconomies of scale: study

Austria and Slovenia are the only European countries whose defence ministries have committed to reaching net zero military emissions, according to an analysis of 30 European countries (EU 27 plus Norway, Switzerland and UK). An article in the Guardian on the analysis added that only about one-third have worked out the size of their carbon … Continue reading Energy in Demand News, June 1-2, 2025
There are mounting calls for international cooperation to ensure production of “critical” minerals is sustainable and equitable
As countries rush to secure supplies of the materials needed to ramp up clean energy, a push for stronger governance rules is gathering momentum. Chloé Farand writes on the Climate Home News website about the plans for an international treaty. Does the world need a global treaty on energy transition minerals? Electric vehicles, batteries, … Continue reading There are mounting calls for international cooperation to ensure production of “critical” minerals is sustainable and equitable
Energy in Demand News, May 25-26, 2025
While there has been more environmental reporting, there have also been more academic studies that prove that there are serious grounds for doubt about the published environmental results. A Financial Times newsletter refers to one draft paper from King’s College London that uses data from Climate Trace, an open-access initiative that takes inputs from more … Continue reading Energy in Demand News, May 25-26, 2025
Social Climate Fund could subsidise up to 20 million heat pumps across Europe, new study finds
A new study finds that investing just one-third of the Social Climate Fund, the EU could subsidise up to 20 million heat pumps across the EU by 2032. This would be enough to reach all energy-poor households in nine EU countries and slash EU gas demand by 11% — nearly as much as the EU imported from Russia in 2024. The EU Social … Continue reading Social Climate Fund could subsidise up to 20 million heat pumps across Europe, new study finds

In an article about the paradox of climate adaptation spending, a Financial Times newsletter says that many global companies recognise the seriousness of climate-related risks to their business, with 66% of the EU businesses polled confirming that they face threats from the physical impacts of climate change. But, according to the survey last year by … Continue reading Energy in Demand News, May 18-19, 2025
EU transmission network risks being ‘systemic handbrake’ in clean energy transition
Over 1,700 gigawatts of renewable energy projects across 16 countries are stuck in the queue to be connected to the electricity grid. Rosie Frost writes on the Euronews website about a new report that analyses many of the challenges facing Europe to maintain the momentum for its clean energy transition. Europe’s electricity grid is … Continue reading EU transmission network risks being ‘systemic handbrake’ in clean energy transition
Blog by Ellie Gabel: How virtual power plants Are revolutionizing grid management
Virtual power plants — VPPs — are emerging solutions to meet the world’s growing energy needs. Products such as electric cars have increased demand, while frequent temperature extremes strain the grid as people try to keep their homes and businesses comfortable. VPPs are decentralized small-to-medium-sized energy sources that are aggregated and managed to keep existing … Continue reading Blog by Ellie Gabel: How virtual power plants Are revolutionizing grid management
South Africa, as G20 president, should push for fossil fuel subsidies to be shifted into funding cleaner energy and climate adaptation
In an article on The Conversation website, Llewellyn Leonard, Professor of Environmental Science, University of South Africa makes the case for South Africa, as this year’s presiden tof the G20, to push to eliminate subsidies for fossil fuels in order to promote cleaner energy. Fossil fuels are still subsidised: G20 could push for the … Continue reading South Africa, as G20 president, should push for fossil fuel subsidies to be shifted into funding cleaner energy and climate adaptation
