Energy consumption is strongly linked to health and wellbeing, in particular life expectancy, infant mortality, happiness, food supply, access to basic sanitation services and access to electricity. But as Josie Garthwaite at Stanford University explains, new research is saying that those improvements cease above a certain number of gigajoules per person per year. Knowing that number will make understanding and setting targets much easier. For a … [Read more...]
How could Germany wind down Russian oil imports by the end of 2022
Berlin has said that, though difficult, it could become independent of Russian oil imports by the end of 2022, with a target of halving them by the middle of the year. Kerstine Appunn at Clean Energy Wire compiles information on the practical challenges for Germanyâs oil infrastructure, refineries and security of supply. Germany is serviced by three pipeline systems for the west, the east and the south of the country. But they are not connected … [Read more...]
Post-war Ukraine needs energy independence, decarbonisation and EU cooperation
Energy independence is a choice for some countries. For Ukraine it is a life-or-death necessity, says Andriy Konechenkov, VP of the World Wind Energy Association and Chairman of the Ukrainian Wind Energy Association, in this op-ed. The Russian invasion has exposed the vulnerability of Ukraineâs current energy system. Many of its fossil-fuelled power plants are near the Russian border, exposing them to disruption by the invading neighbour. The … [Read more...]
Europeâs long-term energy security: do not become dependent on âgreenâ Russiaâs future LNG and Hydrogen exports
Itâs not enough for Europe to cut Russian energy imports without a plan to make the change endure, says Leslie Palti-Guzman writing for the Atlantic Council Global Energy Center. Boycotts and divestments usually have expiry dates. Whatâs more, Russia will be proactive in driving its export capabilities to make them commercially attractive in the post-war world. Russia plans expanding LNG shipments from its Yamal Peninsular, as well as getting … [Read more...]
46% of Buildings âEmbodied Carbonâ can be slashed at little to no cost
Buildings and their construction account for around 40% of all carbon emissions today. Half those emissions come from the construction alone, so buildings successfully powered by clean energy wonât come close to fixing the whole problem. John Matson and Rebecca Esau at RMI describe how industry leaders are creating the tools to measure and gather data on the âembodied carbonâ in building materials (concrete, rebar, glazing, insulation, other … [Read more...]
Q&A: How fast can renewables deliver on Germany’s new energy independence goals?
How quickly can Germany reduce its dependence on fossil fuels? Benjamin Wehrmann at Clean Energy Wire asks six practical questions that must be answered, then gathers the expert answers. What are the current expansion goals for wind, solar and other renewables? Following Russiaâs invasion of Ukraine, will the new emergency plans bring an end to Russian imports as well as reach climate targets? Are renewable power companies ready to deliver a fast … [Read more...]
Aviation policy alert: non-CO2 emissions have up to four times the climate impact
Thereâs little point designing CO2 policies without knowing what other factors are heating up the atmosphere. So it is with aviation. The non-CO2 emissions (aromatics, NOx, SO2, H2O, particulate matter, etc.) from jet engines have up to four times the effect of CO2. You can see it in the contrail cirrus streaks trailing behind aircraft. Carlos LĂłpez de la Osa at Transport & Environment summarises their recent summit that brought together … [Read more...]
An open-source standardised toolkit for modelling Marine Energy
New innovations need a lot of high quality modelling. That means collecting real world data, then coding the programs that run the models. This is labour intensive and takes time to do properly. The modelling needs to be standardised too, otherwise direct comparisons between competing ideas are virtually impossible. Caitlin McDermott-Murphy at NREL describes the latest version of their Marine and Hydrokinetic Toolkit (MHKiT)Â for modelling a wide … [Read more...]
Fossil Fuel divestment is premature: instead, enable investment to keep prices low, and tax consumption
We need to shift investment from fossil fuels to other climate-friendly energy sources, but it must be done more intelligently than weâre doing it today, says Schalk Cloete. The rapid global economic development needed to uplift the 86% of the worldâs population currently living below $1,000/month is inextricably linked to the continued and timely growth in an abundant supply of affordable energy. It would be unjust â and probably futile â to … [Read more...]
Worldâs biggest Carbon Capture project: Shute Creekâs âsell or ventâ business model isnât working
ExxonMobilâs Shute Creek CCUS facility is the worldâs largest carbon capture project. But since its launch in the 1980s half of that CO2 has been vented into the atmosphere, with most of the rest sold for pumping it underground to push out more oil from depleted wells (called Enhanced Oil Recovery). Only 3% has been sequestered underground, explain Bruce Robertson and Milad Mousavian at IEEFA, following their study based on publicly available … [Read more...]
Buildings Renovation: if Europe had started a decade ago it wouldnât have a Russian oil & gas problem
Itâs a message we are starting to see a lot. If ambitious climate policies struggling to be implemented today had been launched a decade ago, Europe wouldnât have a Russian oil and gas problem. Andreas RĂŒdinger at IDDRI looks at buildings renovations in France. Two missed targets, proposed in 2008, are a 38% reduction in energy consumption in existing buildings by 2020, and 400,000 âmajorâ renovations annually. If they had been met, natural gas … [Read more...]
Price volatility and greenwashing: do Gas and LNG make economic or climate sense?
While governments urgently rethink their gas policies, Christina Ng and Sam Reynolds at IEEFA summarise the evidence against the claim that gas and LNG can be green and have a sound economic future. Firstly, most measurements of emissions do not include the full life-cycle of production. For LNG that includes extraction, transport, liquefaction, and re-gasification. They point at studies that say it can be almost as much as the emissions produced … [Read more...]
Could nano-scale filters for isolating CO2, Hydrogen and Biogas accelerate the energy transition?
Nano-scale filters have been developed to separate out molecules like CO2 and hydrogen from gaseous streams. The research, led by MIT, could open a new door to raising the efficiency of carbon capture, isolating hydrogen for fuel use, and the purification of biogas fuel from waste. David Chandler at MIT explains how it would replace century-old methods of separating gaseous molecules that use energy-intensive and hard-to-electrify high … [Read more...]
âOptions to Reform the EU ETSâ: coping with price volatility and speculation (event summary)
Sara Stefanini provides a written summary of our panel discussion held on 31st March 2022, âOptions to Reform the EU ETSâ. Itâs 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 Energyâs Energy Information Administration (EIA) has released its influential 2022 âAnnual Energy Outlookâ (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...]
