Sara Stefanini provides a written summary of our panel discussion held on 31st March 2022, “Options to Reform the EU ETS”. It’s a full summary of the 90 minute discussion (with a link to the video), but it begins conveniently with a summary of the highlights, leading with the role of financial players, who they are, the causes of price volatility, what reforms can create stability, and the cost of decarbonisation. The main concern is speculation … [Read more...]
U.S. EIA Annual Energy Outlook 2022 reveals no reduction in emissions to 2050
The U.S. Department of Energy’s Energy Information Administration (EIA) has released its influential 2022 “Annual Energy Outlook” (AEO2022) which projects the electricity mix over the next 30 years. The modelling takes policies and global conditions as they were in November 2021, so the current Russia-Ukraine crisis is not accounted for, nor any future unforeseeable shocks, and assumes no new policies to 2050. Sandra Sattler at the Union of … [Read more...]
Lower driving speeds + more: behaviour change can make up for 2.7m barrels/day loss of Russian oil imports
Russia normally exports 5m barrels of oil a day. Sanctions may now see Ukraine-supporting nations refuse to buy 3m of them. Can those nations cut their consumption by the same amount, immediately, and stop shortages and further price rises? Yes, says Lucas Davis at the Haas School of Business. Following the Russia-Ukraine crisis, the IEA has released a report “A 10-Point Plan to Cut Oil Use”, with ten ideas for immediate actions in advanced … [Read more...]
The metals sector should back global carbon taxes. It’ll be good for business
Most of the metals mining sector has been opposing carbon taxes. This is a foolish mistake that works against their interests, argue Sally Innis, Benjamin Cox, John Steen and Nadja Kunz at the University of British Columbia. The tax on the carbon emissions from mining and producing most metals (with only aluminium and steel being outliers) are small compared to the price of the metal, so a carbon tax will add little to the selling price. But the … [Read more...]
“Floato-voltaics”: floating solar farms on existing municipal water reservoirs
The municipality of Cohoes, population 17,000, in New York State, is building a floating solar farm on its 10-acre water reservoir. It should power all the city-owned buildings and streetlights, save $500,000/year in electricity costs and still leave 40% of the generated electricity remaining for other civic use. It will cost $6m. It will be a first for a U.S. city, explains Connor O'Neil at NREL. The case for city “floato-voltaics” is so … [Read more...]
All estimates of the ‘cost’ of climate action should include the savings and benefits
Too many climate mitigation scenarios calculate the cost of that transition without measuring the savings and benefits, explain Alexandre Köberle and Joeri Rogelj at Imperial College London, Toon Vandyck at the EC's Joint Research Centre, and Celine Guivarch at the Centre International de Recherche sur l’Environnement et le Developpement, writing for Carbon Brief. This leads to a pessimistic view of the challenges ahead, and public aversion to … [Read more...]
Will turning down Europe’s thermostats ease the Gas supply crisis?
To counter the extremely high gas prices caused by the Russia-Ukraine crisis the IEA has proposed turning thermostats down in households to use less gas. The IEA estimated lowering the heating by just 1°C would reduce gas demand by around 10 bn cubic metres a year, or 7% of Europe’s annual imports from Russia. Aurore Julien at the University of East London looks at quantifiable past attempts around the world to get citizens to cut their energy … [Read more...]
Russia-Ukraine: Support for U.S. Oil & Gas producers must tie them to low-emissions investments
Like many countries, the U.S. is set to raise oil and gas production to compensate for cuts in Russian imports consequent to the war in Ukraine. The danger is that short-term solutions to sky rocketing fossil fuel prices will taking precedence over climate targets. But Ben Cahill at CSIS explains how this is an opportunity for the Biden administration to give support to fossil energy producers with one hand and extract solid commitments on … [Read more...]
Why sustainable Buildings are critical for a resilient, healthier society
Europe and its Member States are committing large sums to buildings renovations. The policy emphasis has been on insulation, energy savings and emissions reduction. The latest Healthy Homes Barometer 2022 by Velux draws attention to the health benefits of renovations that target damp, lack of daylight, excess noise or cold, and other indoor climate hazards. To get an idea of the scale of the problem, 34 million Europeans are unable to keep their … [Read more...]
What can replace Russian gas: modelling Germany’s options on renewables, coal, nuclear, LNG, lowering thermostats
A sudden cut in Russian gas imports means Germany will have to cope with the loss of TWhs. How? Tobias Federico at Energy Brainpool wants decision-makers to get the facts straight. He uses modelling tools to answer this question that is causing fierce debate. The first thing to note is that the loss of gas TWhs (of the order of 100TWh) will be most felt in the provision of heat over winter. Heating systems mostly depends on gas, so intermittent … [Read more...]
Using electrostatic repulsion to clean Solar panels, avoiding up to 30% power loss
Dust build-up on solar panels can reduce the power output by as much as 30% in just one month. Even a 1% reduction in power for a 150MW solar installation could result in a $200,000 (€180,000) loss in annual revenue. Cleaning normally requires purified water, but that needs to be trucked in to prime locations like deserts where solar potential is highest. Cleaning with brushes is labour intensive and can damage surfaces irreparably. David … [Read more...]
Russia-Ukraine and Europe’s energy strategy: a snapshot of a fast-moving crisis
Every day brings news of how Europe’s energy policy is reacting to Russia’s invasion of Ukraine. It’s a big topic and fast moving. Helen Farrell gives a summary of the situation so far. She lists some of the major U-turns at both EU and national levels, the IEA’s ten-point recommendations, the feasibility and repercussions of cutting Russian fossil imports, the prospects for clean energy (solar, wind, nuclear, storage) and our net zero targets. … [Read more...]
Event summary: “Unlocking the potential of Bioenergy”
Sara Stefanini provides a written summary of our panel discussion held on Thursday March 17th 2022. It’s a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights (potential for bioenergy, hard-to-abate sectors, sustainability, policy needs). Those highlights include the need to scale bioenergy up from around 50 EJ today to 150 EJ by 2050; the importance of carbon … [Read more...]
Energy Charter Treaty: four ways to amend it and enable green investments
The European Green Deal (EGD) aims to mobilise at least €1 trillion in sustainable investments over the next decade. But the Energy Charter Treaty (ECT) in its current form - designed to protect cross-border investments, enabling those whose energy projects have been shut down to sue nations – is causing fierce debate. The ECT protects all investment alike, but the result has been fossil (and nuclear) investors suing nations that have curtailed … [Read more...]
What is Energy Security? And what it isn’t
What is energy security? That’s what Maximilian Auffhammer at the Energy Institute at Haas asks and tries to answer, and he starts by saying what it is not and what solutions should not be used. Not importing won’t help because prices are global. “Energy security” can’t be taxed as an externality for much the same reason. Subsidising high prices for consumers decreases the value of energy efficiency investments. Instead, Auffhammer says the … [Read more...]
