The clean energy economy is making its mark on global GDP, explain Laura Cozzi, Timur GĂĽl, Thomas Spencer and Peter Levi at the IEA. It accounted for 10% of global GDP growth in 2023, primarily through three activities: manufacturing of clean energy technologies, deployment of clean power capacity, and clean equipment sales. Here, the authors present the in-depth results for four of the largest economies: the U.S, the EU, China and India, which … [Read more...]
Can the six Gulf nations meet their ambitious Renewables deployment plans by 2030?
The six Gulf Cooperation Council (GCC) countries (Bahrain, Kuwait, Oman, Qatar, Saudi Arabi, UAE) have all set themselves ambitious renewable energy targets to meet in the next ten years. They are some of the sunniest countries in the world, and existing projects have set records for low solar power costs. But they have a long way to go. In 2022, GCC renewable capacity was 5.7GW, primarily solar PV, out of 165GW of total generating capacity, … [Read more...]
Explainer: The EU’s Green Deal Industrial Plan
Here, the Florence School of Regulation (FSR) provides a summary of the Green Deal Industrial Plan. It’s broken up into: What is the Green Deal Industrial Plan? What are critical raw materials and why do they matter? Where is the EU currently standing on critical raw materials? What is the EU doing about critical raw materials? Where is the EU currently standing on clean tech? How is the EU attempting to boost its domestic clean tech sector? Can … [Read more...]
Study: will sight of a Wind Turbine reduce your property prices?
Onshore wind turbines have a permitting problem in the U.S. and Europe. One main complaint from homeowners is that they believe the sight of a turbine will reduce their property value. Maximilian Auffhammer at the Energy Institute at Haas describes his co-authored published study that tests this assumption. The study looks at sale prices of over 300m homes in the U.S. within 10km of a turbine, sold between 1990 and before COVID hit. The clever … [Read more...]
Who is winning the Clean Energy race between China, Europe, and the US?
“X-Change: The Race to the Top” is the fourth report of an RMI series that reviews the cleantech competition between China, Europe, and the US. Kingsmill Bond, Sam Butler-Sloss and Daan Walter at RMI summarise the findings of the latest report, along with six charts, which focuses on four areas: clean technology supply chains, solar and wind deployment, EV sales, and electrification. Solar and wind deployment is still a close contest. But China … [Read more...]
New Offshore Wind projects: is permitting being slowed by evidence from “grey literature”?
Offshore wind is the new frontier of clean energy generation. The permitting process depends on policymakers’ evaluation of the impact assessment evidence. As Claire Szostek at the Plymouth Marine Laboratory explains, that evidence has two sources: primary and “grey” literature. “Primary literature” comes from structured peer-reviewed scientific journals. “Grey literature” includes all other types of reports and evidence published freely. The … [Read more...]
Solar PV technology improvements are rapid. But how do you test the long-term reliability of the new designs?
Solar PV module technology moves fast, and is delivering improvements continuously. So fast that it’s no trivial matter to judge the long-term reliability of the changes. It’s a crucial issue as modules, once deployed, are expected to deliver results over lifetimes that span decades. Sara Fall and Jarett Zuboy at NREL describes a process designed to identify and address potential reliability problems quickly, before they are observed in the … [Read more...]
Tomorrow’s deep water Floating Wind Turbines: the six main design categories explained
The new frontier of offshore wind power is floating wind turbines. That’s because they can be installed in deep water where wind speeds are consistently higher. The new designs have the floating turbines, that bob and sway with the waves and wind, stabilised with ballast or anchored with chains to the seafloor. Emma Edwards at Oxford University looks at the six major categories of design: Spar, Barge, Tension-leg platform, Semi-submersible, … [Read more...]
The European Green Deal isn’t coping with a turbulent world. What must change?
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 “How Can the Green Deal Adapt to a Brutal World?” 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 world’s energy educational … [Read more...]
Two years on, how is Russia’s invasion of Ukraine driving energy security and decarbonisation?
Russia’s 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 GrĂĽnwald 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. It’s 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 we’re still short 20% of our 2030 target
The IEA has released the 143-page “Renewables 2023”, 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...]
