Press reports of China hoping to strike deals with the Taliban to secure mineral rights in Afghanistan are very likely to be an exaggeration, explains Lukas TrakimaviÄius. Itâs true that China wants minerals essential to the clean energy transition and other technologies. Itâs also true that Afghanistan has an abundance (copper, cobalt, lithium, rare earths, etc.), and theyâre worth something of the order of $1tn. But it can take a decade to get … [Read more...]
How Clean Energy Standards have driven clean electrification in the U.S.
John Rogers at the Union of Concerned Scientists presents evidence from the U.S. of the effectiveness of using standards to drive clean electrification. In principle itâs simple: set a legal requirement for the percentage of clean electricity. How itâs done depends on the efforts of all the actors affected. 30 states are using different versions of Clean Energy Standards (CES) â the first began in 1983 and more than half of them began before 2004 … [Read more...]
EU, U.S. exploring new sources of Rare Earth Minerals, should China limit exports
Reports are emerging that China is considering the restriction of the export of rare earth minerals, as a result of tensions with the U.S. Given China controls around 80% of global supply it would have severe consequences for not just advanced military applications (the presumed primary target) but also clean energy technologies like EVs and wind turbines. However, if the threat is carried out, Lukas TrakimaviÄius explains how this could backfire … [Read more...]
Online condition monitoring: making sense of sensors in the age of the Smart Grid
Grid operators across Europe are experiencing higher maintenance and reinforcement costs than ever before and, without significant increases in funding, are realising that they must fundamentally change the way that their assets are operated, maintained and replaced. This means running assets closer to their operational limits, performing predictive rather than corrective maintenance and replacing assets as close to the end of their useful life … [Read more...]
Battery manufacture must take a global leap forward to ensure a sustainable and just transition
The global battery market is surging. By 2040 the global energy storage market is projected to attract $620 billion of investment. Over the past decade, the rechargeable lithium-ion battery market doubled on average every three years. To cope with this growth, we need the development of a sustainable and low-carbon value chain for batteries in order to contribute to the implementation of the 2015 Paris Climate Agreement, says Martin BrudermĂŒller, … [Read more...]
Solar energy is green. Solar panels are not. AI can revolutionise their design
Solar panels are manufactured at 2,000ËC, a temperature so high it requires fossil-fuel power. They are also made using rare earth elements, the supply of which has both capacity and political issues. A new and global project is using artificial intelligence (AI) to rapidly create new designs with new materials that can make their manufacture greener and cheaper. The new designs may even bring their manufacture back to your home country, says … [Read more...]
Why there is so much aggressive bidding at renewables auctions â and what the risks are
Renewable energy auctions have seen very low prices in many parts of the world. Why do auctions seem to be so effective in driving down costs â and what are the risks? Ana Amazo-Blanco, Silvana Tiedemann of Navigant[1], and Dr. Stephen Tay and Monika Bieri of SERIS looked at a solar PV rooftop auction in Singapore and an offshore wind auction in Germany to discover the key factors behind the bids and suggest how project developers can make sure … [Read more...]
A common goal for all sustainability advocates
Nothing is better for fossil fuel interests than current government policies supporting wind, solar and electric cars, writes independent researcher Schalk Cloete. These green technologies won't reduce fossil fuel consumption sufficiently for a long time to come, so the fossil fuel sector will be able to survive that much longer. In the third and last part of a series on green technology-forcing, Cloete calls on all sustainability advocates to … [Read more...]
If solar panels are so clean, why do they produce so much toxic waste?
The disposal of used solar panels is a huge and growing problem that is not being sufficiently addressed, writes Michael Shellenberger, founder of the pro-nuclear citizens movement Environmental Progress (EP). He argues that a fee should be imposed on solar panels which should go into a fund to pay for recyling and clean-up. … [Read more...]
Planned Kosovo lignite power plant fails to commit to cleaner technologies
London-listed, global energy investor ContourGlobal portrays its plans for a new coal power plant in Kosovo as a step towards cleaner air, but its legal agreement with the government shows that it fails to commit to best-in-class environmental performance, writes energy finance consultant Gerard Wynn.

11 ways the Paris climate deal is working in the real world
As climate talks stall, itâs clear the UN process is no longer the major driving force of the climate transition, write Soila Apparicio, Megan Darby and Karl Mathiesen of Climate Home News. While diplomates are negotiating the complex rules of the Paris deal, businesses, researchers, governments and citizens are coming up with new ways to move the climate to a safer place.

‘Tsunami’ of hydropower dam building threatens Europe’s last wild rivers â campaigners
The transition to low-carbon energy sources in the Balkans could cause irreversible environmental damage, environmentalists fear. Proposed hydropower dam constructions endanger Europeâs last wild rivers and some diversity hotspots, writes Umberto Bacchi of Thomson Reuters Foundation.

How to ensure resilience in the grid of the future
A low-carbon world is an electrified world. But electricity has an Achilles heel: it is vulnerable. And will become more so as digitalization progresses and extreme weather increases, notes Mark Byrne of the Total Environment Centre in Australia. To reduce vulnerability, Byrne believes we need to create a system of enmeshed micro-grids. Keywords: âmutual interdependenceâ. Â … [Read more...]
As the energy potential of the Eastern Mediterranean grows, so does the potential for conflict
The United States and the European Union should play a more proactive role in defusing the growing tensions over energy resources in the Eastern Mediterranean, writes David Koranyi of the Atlantic Council Global Energy Institute. … [Read more...]
Meet the new ârenewable superpowersâ: nations that boss the materials used for wind and solar
Countries that create green energy infrastructure now, before political and economic control shifts to a new group of ârenewable superpowersâ, will be less susceptible to outside influence in the future, writes Andrew Barron, a professor of Swansea University. Article courtesy The Conversation. … [Read more...]
