Announced at COP28, a total of 123 countries committed to tripling renewable power capacity and doubling energy efficiency by 2030. China didn’t. Why? Quoting experts, Lin Zi at China Dialogue explains that the bundling together of the two targets is the problem. Tripling renewables is very achievable; in fact China may well exceed that target. But reducing energy intensity is not easy, even though China has a good record: among the G20 members, … [Read more...]
Global inflation: high borrowing costs threaten the continued growth in Renewables. What must be done?
Over the last decade, investors and governments got used to two supportive trends: relatively cheap capital from low interest rates, and steadily falling costs. However, this changed as the world emerged from the Covid pandemic and into the global energy crisis. In a new era of high interest rates, the impressive growth in renewables deployment is under threat, explain Tim Gould, David Fischer, Paolo Frankl and Heymi Bahar at the IEA. Renewables … [Read more...]
Another good year for Renewables. But can we triple Wind and Solar by 2030?
COP28 saw a calling for a tripling of renewable capacities by 2030, off the back of positive signs. In 2022, 80% of incremental power demand and 12% of electricity generated worldwide came from solar and wind. And the IEA believes solar generation can grow at 25% to 2030. But, as Ramnath Iyer at IEEFA explains, specific challenges must be met to ramp up successfully. The non-financial barriers include a lack of policy clarity, permitting, and … [Read more...]
Four net-zero opportunities for 2024: wind, solar, lab-grown meat, positive tipping points
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...]
China is still playing the long game with its ‘new three’: solar cells, lithium batteries, EVs
China’s “new three” – or xin san yang – are solar cells, lithium-ion batteries, and EVs. The term harks back to the concept of its “old three” that were once the pillars of its exports: clothing, home appliances and furniture. China’s success is seen in the numbers: it accounts globally for 80%+ of solar cell exports, 50%+ of lithium-ion batteries and 20%+ of EVs. You Xiaoying, writing for China Dialogue, interviews experts and quotes reports … [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...]
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...]
Making Fuel Cells cheap enough for mainstream use: can Cobalt nanoparticles replace Platinum as catalysts?
Fuel cells could be a game-changer in decarbonisation. They efficiently convert chemical energy into electricity with only water and heat as byproducts. One of the most promising types is the PEMFC (polymer electrolyte membrane fuel cell) because of its applications in transportation, as well as stationary power sources. But it can’t go mainstream until the costs come down, specifically the platinum catalysts. Platinum is scarce and expensive. … [Read more...]
New Solar study: 50% of global power by 2050, even without more ambitious climate policies
Nadia Ameli at UCL and Femke Nijsse and Jean-Francois Mercure at the University of Exeter present their study that shows solar is on track to make up more than half of global electricity generation by 2050, even without more ambitious climate policies. This far exceeds any previous estimates: last year’s IEA World Energy Outlook predicted that solar would account for only 25% by 2050. The authors’ macroeconomic model takes the latest … [Read more...]
EU now has 9,000+ “energy communities”: smart, decentralised, flexible generation and consumption
The goal of the EU’s “Clean Energy for all Europeans package” (CEP), adopted in 2019, is to improve the functioning and design of Europe’s energy markets and systems. Luca Arfini, writing for ESCI, explains how, as part of the CEP, new market actors called “active customers/consumers and citizens” and “energy communities” are being established. As variable renewable generation grows, the whole system needs to be more decentralised, smarter and … [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...]
1,500GW of Renewables deployment delayed globally because Grids aren’t modernising fast enough
A first-of-its-kind global country-by-country study, “Electricity Grids and Secure Energy Transitions” by the IEA finds that electricity grids are not keeping pace with the rapid growth of clean energy technologies. Without greater policy attention and investment, shortfalls in the reach and quality of grid infrastructure puts at risk our climate goals. Worldwide, we need to add or replace 80m kms of power lines by 2040 – an amount equal to the … [Read more...]
