The European Green Deal was not designed to cope with the extraordinary series of overlapping crises the world has been facing. Though the EU has ultimately been reinforced through crises, that may not continue, explain Marc-Antoine Eyl-Mazzega and Diana-Paula Gherasim at IFRI who summarise their study âHow Can the Green Deal Adapt to a Brutal World?â Costs are rising and investment is not keeping pace. Dependence on China and the burst of … [Read more...]
Study: universities worldwide are still producing far more graduates for fossil fuels than for clean energy
Universities worldwide still produce more workers for fossil fuels than for renewable energy industries. Roman Vakulchuk and Indra Overland at the Norwegian Institute of International Affairs summarise their new study on the energy transition in global higher education, published by the Energy Research & Social Science journal. The study is based on a review of 18,400 universities in 196 countries. 68% of the worldâs energy educational … [Read more...]
Two years on, how is Russiaâs invasion of Ukraine driving energy security and decarbonisation?
Russiaâs invasion of Ukraine has boosted anxiety and therefore action on energy security and dependence on oil and gas. Sanctioning Russian oil and gas imports is an opportunity to replace fossil fuels with low or no carbon alternatives, an opportunity that is being taken. And renewables like wind and solar are by their nature local and therefore good for energy security (though with notable exceptions). Charles Hendry, Ellen Wald, Olga Khakova, … [Read more...]
Electrostatic Generator fabrics can capture energy from cars depressing roads, swaying buildings + more
Literally anything that moves is using energy that can be harnessed. Not just waves rolling toward shore but cars depressing roads, buildings swaying in the wind, and much more. One way to harness it is to create a material that can be woven into the fabric of roads and buildings so that it captures the energy and converts it into electricity. Caitlin McDermott-Murphy at NREL describes research into Hexagonal Distributed Embedded Energy … [Read more...]
Tandem solar cells (perovskite + silicon) can reach 40% energy conversion rates
Tandem solar lays new perovskite cells over standard silicon cells. Perovskite absorbs the shorter wavelengths of light that silicon misses. So the thin layer of perovskite collects the visible wavelengths, and lets the near-infrared light through to the silicon underneath. Martina GrĂźnwald and Sarah Michaud writing for the WEF point at the results of R&D and demonstrations in Germany, Switzerland, Saudi Arabia and China. Energy conversion … [Read more...]
Recyclable, plant-based glue cuts carbon footprint of Wind Turbines
Everyone knows that wind and solar have significant carbon footprints because of the energy and materials that go into the manufacture of their components. Itâs why research continues on how to get that footprint down. Emily Mercer at NREL describes research there that has developed a glue, used to hold a wind turbine blade together, made of resin made from plant waste using a low-energy process, and is easily recycled. In contrast to the current … [Read more...]
Massive global expansion of Renewables coming. But weâre still short 20% of our 2030 target
The IEA has released the 143-page âRenewables 2023â, the latest edition of its annual report on the sector. The world added 50% more renewable capacity in 2023 than in 2022 and the next 5 years will see fastest growth yet. Under current policies and market conditions, global renewable capacity is already on course to increase by two-and-a-half times by 2030: great news but still short of the tripling we need. A key reason for the gap is the lack … [Read more...]
Clean energy forecast map tells firms where to build their facilities to minimise emissions
For companies that are serious about their net-zero targets, where you run a facility affects your results. Building a new facility in a region where renewables are ramping up will keep your emissions low. Connor O'Neil at NREL explains how analysts there, in partnership with Amazon, are building out datasets that take a forward look at where clean energy is growing. The âCambiumâ data sets contain modelled hourly emission, cost, and operational … [Read more...]
China didnât sign the global pledge to triple Renewables and double Efficiency. Why?
Announced at COP28, a total of 123 countries committed to tripling renewable power capacity and doubling energy efficiency by 2030. China didnât. 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 ânew threeâ: solar cells, lithium batteries, EVs
Chinaâs ânew threeâ â or xin san yang â are solar cells, lithium-ion batteries, and EVs. The term harks back to the concept of its âold threeâ that were once the pillars of its exports: clothing, home appliances and furniture. Chinaâs 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 Windâs 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. Thatâs why it put its climate reputation at risk in October when the state government announced it would not renegotiate contracts with offshore wind providers Ărsted, 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 IEAâs 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...]
