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...]
The world needs 200,000 Offshore Wind turbines by 2050: mapping the locations, constraints
Hugo Putuhena, Fraser Sturt and Susan Gourvenec at the University of Southampton summarise the results of their methodology that determines where to locate the hundreds of thousands more offshore wind turbines the world needs to meet net-zero targets. The world may need as many as 200,000 offshore turbines by 2050, generating 2,000GW. At the end of 2022, 63GW had been installed worldwide, so that means 32 times current capacity. If the “power … [Read more...]
Only certain types of Hybridisation (Wind or Solar + Storage) beat building expensive transmission lines
In some regions, the roll out of new wind and solar has outpaced new transmission. That causes “congestion” at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. That’s certainly the case in the U.S. now. One answer is “hybridisation” where storage is built alongside the renewables, to save that excess power for when it can be sold later. Julie Mulvaney Kemp at … [Read more...]
EU’s 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesn’t make sense
The proposed Net Zero Industry Act includes a target for the EU to manufacture domestically at least 40% of its cleantech deployment needs by 2030. That includes the key technologies of solar PV panels, wind turbines (onshore and offshore), EV batteries, heat pumps and hydrogen electrolysers. But it doesn’t make sense to have the same 40% target for all, explain Giovanni Sgaravatti, Simone Tagliapietra and Cecilia Trasi at Bruegel. The main … [Read more...]
How will China respond to the EU’s “40% made at home” clean energy tech ambition
The EU’s Net Zero Industry Act wants to drive home-grown production of eight “strategic” net-zero technologies, including solar, wind, batteries and CCS. The target is 40% made at home, though the policy is yet to be worked out. You Xiaoying writing for China Dialogue talks to experts in China and the EU for their predictions. Most say that Chinese firms are not very worried. Firstly, they can – and are already making moves to – set up production … [Read more...]
IEA report: global manufacturing capacity is expanding rapidly for solar, wind, batteries, electrolysers, heat pumps
The IEA summarises its special briefing, “The State of Clean Technology Manufacturing.” It’s a global update on recent progress in key regions, focussing on five technologies – solar PV, wind, batteries, electrolysers and heat pumps – critical to the energy transition. It should be read to keep decision makers informed of investment trends and the impact of industrial strategies. Overall, manufacturing capacity for these technologies is expanding … [Read more...]
Five charts on the Energy Transition: the 2020s is the decade of maximum disruption. By 2030 the endgame will be clear
Sam Butler-Sloss and Kingsmill Bond at RMI present a succinct summary of why the energy transition matters, how the 2020s is the era of maximum disruption, and how by 2030 the transition’s endgame will be apparent (though far from complete). Four key technologies are already entering the exponential growth stage: solar, wind, EVs and heat pumps. As early as 2030 their cheapness will flush away the fossil equivalents in succeeding decades, say the … [Read more...]
“Exascale” computing algorithms can deliver new Wind Turbine designs and on-site power-maximising strategies
Advances in exascale computing algorithms and models for multiscale atmospheric flows are leading to new wind turbine designs and on-site power-maximising strategies previously not possible, explains Brooke Van Zandt at NREL. The models can contain and process two billion grid points, simulating the air flow around turbines in a large wind farm with unprecedented accuracy. Van Zandt describes how the new tools are being used to deal with highly … [Read more...]
Record clean-power growth in 2023: is Coal and Gas decline now structurally embedded?
Last year, wind and solar reached a record 12% of global electricity generation, according to think tank Ember’s latest global electricity review. The overall share of all forms of low-carbon electricity rose to almost 40% of total generation. Josh Gabbatiss at Carbon Brief goes through the Ember review which heralds this as the moment fossils began their permanent decline. Ember calls it “structural” and “enduring” because previous declines only … [Read more...]
Wind Turbines: how dependent is the EU on China?
Joseph Webster at the Atlantic Council’s Global Energy Center takes stock of the European wind sector’s dependence on China. Nobody wants geopolitics and a worsening relationship with Beijing to disrupt positive cooperation in the urgent energy transition. The news is mostly good: the dependence is low because the international trade in turbines is constrained by weight-to-value ratios, transportation costs, and local content requirements. In … [Read more...]
Turning Ethanol production’s CO2 by-product into E-Fuels using Wind power
With vast open spaces, Midwest states in the U.S. produce millions of gallons of ethanol from corn as well as thousands of kilowatt-hours of electricity from wind farms every year. Research led by NREL is working on using wind power to drive electrolysers that turn the ethanol’s CO2 by-product into e-fuels, explains Erik Ringle at NREL. A typical 50 million-gallon-per-year ethanol plant releases 14 tons of CO2, a natural by-product of … [Read more...]
Renewables “cost of capital” in Europe lower than oil, gas, coal. What the U.S. and China can learn
The ultimate price of anything is highly dependent on the cost of capital needed to put it in place. That cost reflects the risks financial markets perceive. And policy certainty reduces risk. Gireesh Shrimali, Christian Wilson and Xiaoyan Zhou at Oxford University, writing for WEF, summarise their global study which shows the cost of capital for different energy technologies, and therefore which ones will trend upwards and dominate. They cover … [Read more...]
