When electricity markets have high shares of wind and solar – the goal of many regions around the world – is it more efficient to build a nuclear power plant instead of investing further in more renewable capacity? The answer is yes, according to a study by Machiel Mulder, Xinyu Li and Arjen Veenstra at the University of Groningen. In essence, it’s because nuclear benefits from the high (scarcity) prices when there’s little wind or sunshine. Here … [Read more...]
Latest U.S. modelling shows Battery Storage can support an 80% Renewables grid by 2050
NREL’s latest Storage Futures Study concludes that battery storage should be able to support an 80% renewables grid mix in the U.S. by 2050. Madeline Geocaris at NREL explains how they modelled hundreds of future scenarios to accurately represent the value of diurnal (<12 hours) battery energy storage. The high-storage scenarios made different cost and performance assumptions for storage, wind, solar PV, and natural gas. 15 storage … [Read more...]
Will China’s gigantic wind and solar “bases” mean targets met four years early?
China will have doubled its 2020 installed wind and solar capacity by 2025, exceeding 1,100GW, according to government plans. That’s four years sooner than required to meet their target of peak CO2 emissions by 2030 and carbon neutrality before 2060. Writing for Carbon Brief, Lauri Myllyvirta and Xing Zhang at CREA explain that the main driver is the creation of “clean energy bases”: large-scale concentrations of wind and solar power on deserts … [Read more...]
Record Renewables additions for 2021 and 2022 despite supply bottlenecks prove Solar & Wind’s resilience
Despite – or perhaps because of – global market and political turmoil, renewable power is set to break another record in 2022. That’s after 2021 also saw record new capacity from solar, wind and other renewables worldwide. It’s mainly driven by solar PV in China and Europe as governments around the world take advantage of renewables’ energy security and climate benefits, according to the IEA’s latest Renewable Energy Market Update. 295GW of new … [Read more...]
China’s impressive growth in Renewables and Transmission now needs Market innovation

Together they make up most of the total power capacity of over 2,200 GW... STOP PRESS: China's Transition is the biggest single opportunity for managing climate change and also for those businesses who are ready with the innovations that will ensure the best possible outomes in an incredibly … [Read more...]
Solar + Storage Hybrid plants are poised for explosive growth in the U.S.
At the beginning of 2021 the U.S. had 73 solar and 16 wind hybrid projects, amounting to 2.5GW of generation and 0.45GW of storage. By the end of 2021, over a third of the 675GW of solar in the grid connection queue were hybrids, and 19GW were wind hybrids. Only one in four typically get approved, built and connected. But that still points at a twenty-five-fold increase in hybrid generation. It’s why Joachim Seel, Ben Paulos and Will Gorman at … [Read more...]
Pathway for 100% Renewables in 24 U.S. states by 2035
We should not be surprised to see a growing number of 100% renewables roadmaps, with target dates in the 2030s, from nations as the transition gains pace. This study, “On the Road to 100 Percent Renewables” led by The Union of Concerned Scientists (UCS), details how the 24 states that make up the members of the U.S. Climate Alliance (USCA) can meet all of their electricity needs with renewable energy by 2035. Paula Garcia at UCS summarises the … [Read more...]
Europe must simultaneously replace Russia’s fossil exports and accelerate its clean energy deployment
The Ukraine crisis has had an immediate impact on Europe’s strategy for energy supply security. And this week’s sudden halting of gas supplies by Russia to Poland and Bulgaria only emphasises the urgency. Dolf Gielen, Ricardo Gorini, Luis Janeiro and Seán Collins at IRENA look at the best options, basing their findings on their latest “World Energy Transitions Outlook”, published in March, that lays out a routemap for the next eight years for … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraine’s current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
Q&A: How fast can renewables deliver on Germany’s new energy independence goals?
How quickly can Germany reduce its dependence on fossil fuels? Benjamin Wehrmann at Clean Energy Wire asks six practical questions that must be answered, then gathers the expert answers. What are the current expansion goals for wind, solar and other renewables? Following Russia’s invasion of Ukraine, will the new emergency plans bring an end to Russian imports as well as reach climate targets? Are renewable power companies ready to deliver a fast … [Read more...]
Price volatility and greenwashing: do Gas and LNG make economic or climate sense?
While governments urgently rethink their gas policies, Christina Ng and Sam Reynolds at IEEFA summarise the evidence against the claim that gas and LNG can be green and have a sound economic future. Firstly, most measurements of emissions do not include the full life-cycle of production. For LNG that includes extraction, transport, liquefaction, and re-gasification. They point at studies that say it can be almost as much as the emissions produced … [Read more...]
Russia-Ukraine and Europe’s energy strategy: a snapshot of a fast-moving crisis
Every day brings news of how Europe’s energy policy is reacting to Russia’s invasion of Ukraine. It’s a big topic and fast moving. Helen Farrell gives a summary of the situation so far. She lists some of the major U-turns at both EU and national levels, the IEA’s ten-point recommendations, the feasibility and repercussions of cutting Russian fossil imports, the prospects for clean energy (solar, wind, nuclear, storage) and our net zero targets. … [Read more...]
Germany’s electrification ambitions: TSOs scenario for 91% Renewables by 2045
The German TSOs submitted in January scenarios for their grid to 2037, making projections for increasing electrification. In addition, and for the first time, they included an ambitious and long term scenario to 2045. By pure chance, the Russian invasion of Ukraine and Germany’s response – to consider a reduction in its serious dependence on Russian energy imports – should make eyes turn sharply towards that 2045 scenario. Simon Göss at cr.hub, … [Read more...]
A massive expansion of domestic Renewable energy stops wars, not just climate change
Hans-Josef Fell at Energy Watch Group says bluntly that a massive expansion of domestic renewable energy generation over the last decade would not only have saved the planet from a future climate catastrophe, it would be stopping wars today. Firstly, 70% of Russia's state revenues come from oil, natural gas, coal and nuclear energy deals. State revenues fund its military. Secondly, an EU dependent on imports from any geopolitical adversary will … [Read more...]
Critical minerals and materials: supply bottlenecks and risks need international cooperation
The growth in demand for minerals and materials needed for the energy transition is putting a strain on supply. Mining and processing are the two key bottlenecks. Dolf Gielen, Martina Lyons, Francisco Boshell and Peter Chawah at IRENA summarise the multiple challenges. New capacity is not the only problem: the geographical concentration of where the mining and, in particular, the processing is being done is the primary risk. China’s dominance in … [Read more...]
