According to the IEA, without the solar and wind capacity additions made in 2021-23 Europeâs energy costs would have been âŹ100bn higher in those three years, as prices spiked due to Russiaâs 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...]
Rooftop Solar: will subsidies benefit wealthy early adopters, while grid limits lock out the latecomers?
Subsidies encouraging homeowners to install rooftop solar are being won by the affluent who can afford to be first movers. And when the technology has come down in price, the remaining majority of households will be shut out of the benefits of own-generation because the grid wonât have the capacity to integrate everyone. Thatâs the argument made by Juan Jose Cuenca Silva, Barry Hayes and Hannah Daly at the University College Cork who summarise … [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...]
Rooftop Solar for industry: up to 35% of U.S. manufacturing sectors could supply all their own power
Rooftop solar could supply the complete electricity needs of 5-35% of U.S. manufacturing sectors, explains Matthew Eckelman at Northeastern University who summarises his co-authored paper âTechnical feasibility of powering U.S. manufacturing with rooftop solar PVâ. At present, only 0.1% of industrial electricity demand in the U.S. is supplied by on-site sources of renewable energy. But large, unobstructed industrial rooftops and the declining … [Read more...]
Europeâs 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 arenât ready to integrate them. As … [Read more...]
Does Nuclear slow down the scale-up of Wind and Solar? France and Germany canât 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. Germanyâs vision of a fully renewables-based EU is at odds with Franceâs 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...]
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 âcongestionâ at times when the variable renewables are producing too much power locally, and cannot sell the excess, which squeezes profitability. Thatâs certainly the case in the U.S. now. One answer is âhybridisationâ 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...]
Power to the people: citizen-centred Just Transitions challenge energy system centralisation
EU Member States need to phase-out coal and transform their carbon-intensive industries to make Europe climate-neutral. However, these should not be the only goals: transparency and justice must also accompany this path, argue Diana SĂŒsser at IEECP, Serafeim Michas at TEESlab and Ricardo Antonio GarcĂa Mira at the University of A Coruna. As Member States implement their territorial just transition plans, they must ensure they benefit affected … [Read more...]
EUâs 40% domestic Cleantech ambition: same target for Wind (easy) and Solar (hard) doesnât 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 doesnât 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 EUâs â40% made at homeâ clean energy tech ambition
The EUâs Net Zero Industry Act wants to drive home-grown production of eight âstrategicâ 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 â and are already making moves to â 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, âThe State of Clean Technology Manufacturing.â Itâs a global update on recent progress in key regions, focussing on five technologies â solar PV, wind, batteries, electrolysers and heat pumps â 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...]
Community Batteries: when theyâre the best option for overcoming grid constraints. And when theyâre not
Community batteries are a shared asset in neighbourhoods with rooftop solar, avoiding the need for every household to have its own battery. Even people unable to have rooftop solar can use it. Itâs taking off in Australia, supported at both the state and federal level. But Bjorn Sturmberg, Alice Wendy Russell, Hedda Ransan-Cooper, Louise Bardwell and Marnie Shaw at the Australian National University summarise their research which warns that it … [Read more...]
Perovskite: abundant, cheap, printable solar cells demonstrated, ready to generate power
Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. Itâs a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [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 transitionâs 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...]
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 Emberâs 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 âstructuralâ and âenduringâ because previous declines only … [Read more...]
