Will de Freitas at The Conversation draws attention to four reasons to celebrate 2023 and their implications for our drive to tackle climate change. Most will be familiar with the continued progress made with wind and solar, though they deserve repeating given its immense significance. Wind turbines now stand more than a quarter of a kilometre high, and will get taller. At that size, one turn of the blade will power an average home in the … [Read more...]
Another chapter in Offshore Wind’s stop-go story: New York
New York State should be leading the offshore wind ambitions of the U.S. The region enjoys high capacity factors for offshore wind, especially during the peak winter heating season. And New York is used to being a leader in so many things. That’s why it put its climate reputation at risk in October when the state government announced it would not renegotiate contracts with offshore wind providers Ørsted, Equinor and BP, explains Joseph Webster at … [Read more...]
EU Energy Outlook to 2060: power prices and revenues predicted for wind, solar, gas, hydrogen + more
Huangluolun Zhou, Elena Dahlem and Alex Schmitt at Energy Brainpool present their updated “EU Energy Outlook 2060”, modelling how the European energy system will undergo major changes in the coming decades while continuing to guarantee a secure supply and meet its climate targets. What do these developments mean for power prices, revenue potential and risks for solar PV and wind? The two main scenarios are “Central” and “GoHydrogen” for the EU 27 … [Read more...]
Investing billions in new cross-border Electricity Transmission capacity can cover its costs within a few years
The huge divergence of electricity prices between nations after the energy crises of 2021 and 2022 exposed Europe’s pressing need to increase cross-border transmission capacity, explain George Dimopoulos, Conall Heussaff and Georg Zachmann at Bruegel. Without it, generation costs will be higher, emissions too, and new generation will continue to be badly congested. The author’s calculations reveal that one additional MW of cross-border capacity … [Read more...]
Clean energy is driving job growth, but skills shortages are a major barrier
The second edition of the IEA’s annual World Energy Employment report measures energy sector employment by region, fuel, technology, and value chain. Globally, energy employment rose to 67m people in 2022. Over half of employment growth since before the pandemic was in just five sectors: solar, wind, EVs, batteries, heat pumps, and critical minerals mining. In fact, clean energy jobs overtook fossil fuels in 2021. But skilled labour shortages are … [Read more...]
China’s Belt and Road Initiative is now building more Renewables, less Coal
Energy has always made up the majority of investments and construction deals signed through China’s Belt and Road Initiative (BRI). Until very recently these investments were dominated by fossil fuel projects. But in the first half of this year, over 40% of BRI energy projects announced were wind and solar, with 22% each for gas and oil, and zero for coal projects. The reasons include China’s stated commitment to clean energy, avoiding the risk … [Read more...]
Using Generative AI to speed up and improve the Wind Turbine blade design process
Justin Daugherty at NREL describes research there on using generative AI to accelerate and improve the wind turbine blade design process. To keep up with the pace of change in the market (not just customer demands, but policy regulations and technological innovations), the current method uses simplified low-fidelity modelling because it’s quicker to turn around. But it is also less accurate. Researchers are exploring deep-learning models using … [Read more...]
China can learn from the EU about power market design and infrastructure build-out
How will China integrate its growing Variable Renewable Energy generation and create a nationwide energy system that avoids the risks of curtailment, stranded assets and blackouts? A good place to start is to learn from Europe. Helen Farrell at ECECP summarises their report that uses the European experience to model scenarios for China. China’s key challenges is that its power market lacks an effective auxiliary service market, a capacity market, … [Read more...]
EU legislators must avoid crippling clean tech with a blanket ban on PFAS (per-and polyfluoroalkyl substances)
A blanket ban on all types of PFAS (per-and polyfluoroalkyl substances), or ‘forever chemicals’, is currently being considered by the European Chemicals Agency (ECHA). PFAS are used in cleaning products, non-stick pans, personal care products and more, so a ban on these will save lives and deliver sustainable practices. But, as Daniel Fraile at Hydrogen Europe explains, the PFAS subgroups of fluoropolymers and perfluoropolyethers are used in … [Read more...]
Jobs in the new clean energy economy: where are they, what are they, and how to find one
According to IEA figures, in 2019 the energy sector employed over 65m people, 2% of the global workforce. Half of that workforce is already in the clean energy sector, and demand for skilled employees is soaring. Whereas fossil jobs are heavily weighted to low skilled and very high skilled, most clean energy jobs are at the high end. Helena Uhde at Ea Energy Analyses looks at this new world, explains the differences, and notes that although … [Read more...]
Scaling up global grid-scale Storage to 80GW/year (it was 16GW in 2022)
Globally, annual additions of grid-scale battery storage must rise to 80GW between now and 2030, explain Amit Jain, Gabriela Elizondo Azuela and Aakarshan Vaid at the World Bank, writing for WEF. In 2022 it was only 16GW. The biggest gap, perhaps understandably, is in developing countries. It’s in these regions where renewables auctions for deployment – primarily solar and wind – need to start including hybrid storage as part of the package. The … [Read more...]
Though the price shocks hurt, Renewables installed between 2021-23 saved Europe €100bn
According to the IEA, without the solar and wind capacity additions made in 2021-23 Europe’s energy costs would have been €100bn higher in those three years, as prices spiked due to Russia’s invasion of Ukraine and the unexpected drop in output from nuclear and hydro. That money saved is another reason why the ramp up of renewables is so important, explains Joe Myers writing for the World Economic Forum who summarises the IEA data. Natural gas … [Read more...]
Spain: as Renewables rise, managing supply and demand is the next challenge
In May this year Spain reached a landmark day when it was powered 100% by renewables - solar, wind and hydroelectric power - from ten o'clock in the morning until seven o'clock in the evening. In four years the share of renewable energy generation rose from 37% to 50%, while non-renewables dropped from 62% to 49%. Its draft Law on Climate Change and Energy Transition targets 35% of renewable energy in final consumption by 2030 and 100% in the … [Read more...]
Europe’s grid bottlenecks are delaying its energy transition
***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids aren’t ready to integrate them. As … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany can’t agree
France and Germany lead the camps in disagreeing on the future of nuclear in Europe. Camille Lafrance and Benjamin Wehrmann at CLEW take a deep dive into the reasons why, quoting experts and politicians. Germany’s vision of a fully renewables-based EU is at odds with France’s unwavering support for low-carbon nuclear energy. European-wide agreement on targets matter because they drive future investment in the targeted technologies and the design … [Read more...]
