The European Green Deal must grasp the opportunity to kick-start buildings renovations, says Thibaud Voïta at the IFRI Center for Energy & Climate, summarising his report “The Renovation Wave: A Make or Break for the European Green Deal”. A lot of European buildings are old, and progress is slow. Stiffer regulations have helped, and household energy efficiency has risen by 30% since 2000. But the number of deep building renovations completed … [Read more...]
Decarbonising end-use sectors: buildings, transport, industry. Which strategies are best?
The rapid pace of change in the energy sector is a positive sign for the transition. But the disruption it causes creates another big problem. It makes it harder to predict what will happen next. That makes strategies and pathways harder to design, and increases the risk of stranded assets. To try to come to grips with that future, Sean Ratka, Paul Durrant and Francisco Boshell summarise the findings of IRENA's 4-day “Innovation Week” held last … [Read more...]
Changes to national targets and forestry mean EC’s 55% plan is weaker than it looks
The EC’s plan to reduce the bloc’s emissions by 55% by 2030 compared to 1990 levels, instead of the previously agreed 40%, is very welcome but its implementation plan is flawed, says William Todts at Transport & Environment. The EU Emissions Trading System (EU ETS) won’t be enough on its own. So the plan allows nations to include “managing” forests and “tree plantations”, a big change because forests were not part of previous emissions … [Read more...]
City-level emissions reductions: what can successful cities teach us
The EU Covenant of Mayors for Climate and Energy (EUCoM) requires their member cities to commit to exceeding their national goals. EUCoM is one of the world’s largest subnational climate action networks, with over 1,000 cities and home to 50m people. Writing for Carbon Brief, Angel Hsu, Nihit Goyal and Amy Weinfurter at Yale-NUS College review the data to see how successful they have been. About 40% of the cities show emission reductions that are … [Read more...]
Cooling: up-front costs are the barrier to new solutions that cut energy use by two-thirds
Existing, latest technology could be delivering the world’s current air conditioning needs with just a third of the energy use, say Sneha Sachar at the AEEE (India) and Iain Campbell at RMI. The main barrier is the up-front costs. And that’s for everything from improving the thermal efficiency of buildings to accelerating the deployment of the most efficient cutting edge ACs (at present, legal minimums lag behind the best ACs, and the best ACs … [Read more...]
France’s recovery plan: will support for emissions-high sectors compromise a new Green economy?
The French recovery plan, formally presented today, combines emergency rescue measures, economic stimulus and longer-term investments. A substantial €32bn out of the €100bn budgeted is earmarked for the green economy. But Sébastien Treyer at IDDRI asks whether rescue measures for traditionally emissions-high sectors - tourism, aviation, automotive, buildings, agri-food – will collide with climate targets. He references studies that should be used … [Read more...]
New U.S. climate bill is unprecedented in “ambition, concrete details, and urgency”
Mark Silberg, Alisa Petersen and Ben Holland at RMI pick out six highlights from a new U.S. climate bill and accompanying report that they describe as unprecedented in “ambition, concrete details, and urgency”. The Democrat-sponsored “Moving Forward Act” passed the House at the start of July and now goes to the Senate. Though regional commitments already get the U.S. halfway to meeting the 1.5°C goal, federal action is needed for the rest. … [Read more...]
Buildings Efficiency: France must embed deep retrofits into its market
France’s energy efficiency ambitions for buildings are well off target. Buildings account for 28% of the nation’s emissions and they’ve hardly reduced since 1990 – only by 3%. It’s because of the lack of development of the buildings renovation sector, explains Andreas Rüdinger at IDDRI. Without it, there’s little chance of renovating 500,000 housing units per year and bringing the entire housing stock up to the "low-energy building" (BBC) … [Read more...]
The PAC Scenario: net-zero by 2040 to meet Europe’s Paris goals
The EU is not on track to meet its Paris Agreement obligations on emissions and limiting the global temperature rise to 1.5°C. CAN Europe and the European Environmental Bureau (EEB) present their Paris Agreement Compatible (PAC) scenario, designed to do just that. It’s been created through the careful analysis of contributions from more than 150 stakeholders including NGOs, scientists, industry and grid operators. Jörg Mühlenhoff at CAN Europe … [Read more...]
German Geothermal: from 1.2TWh to 100TWh by 2050?
The IEA’s Sustainable Development Scenario sees the world's geothermal power generation tripling to almost 300 TWh by 2030. That’s because there’s an almost unlimited supply that can provide power, heating and cooling. It’s also a continuous supply uninterrupted by the weather, unlike solar and wind. The plants are small and quiet. For heating, ground-source heat pumps use significantly less electricity than other technologies. Writing for CLEW, … [Read more...]
Germany’s Corona stimulus package: what’s in it for energy, climate?
€30bn of Germany’s €130bn Corona economic stimulus package is dedicated to the energy sector and the climate. Simon Göss at Energy Brainpool runs through the four main areas of focus. There’s €11bn to fund a reduction in the EEG levy (renewables surcharge) to help electricity consumers. €9bn goes to creating a hydrogen industry for Germany. There’s €7bn to promote e-mobility (tax exemptions, subsidies, co-financing of charging stations and … [Read more...]
How to cut Full Life-cycle Buildings Emissions
Most efforts to decarbonise buildings are focused on “operational” emissions. That’s because, once constructed, buildings are responsible for a massive 30% of global final energy use and 28% of carbon emissions. But that focus has meant the “embodied” carbon – from the materials, construction, demolition, and recycling of buildings – has received little attention, explain Meng Wang and Yihan Hao at RMI. That’s despite the numbers still being … [Read more...]
UK heating plan still means 120 gas boilers installed for every low-carbon system
Though the UK is a leader in grid electrification it is a poor performer when it comes to the electrification of heating. In May the UK government proposed a clean heat policy to support the switch away from gas heating for 12,500 homes a year for two years. Jan Rosenow and Samuel Thomas at RAP say that looks like business as usual: for every one new low-carbon heating system, more than 120 gas boilers will be installed as normal. In 2019, 1.7m … [Read more...]
Will Member States support the EC’s green recovery plan?
The EC’s “Next Generation EU” plan for a joint loan of €750bn is a major breakthrough as it accepts the need for the member states to share a large debt burden to revive the EU economy. It will be in addition to the European budget under discussion before the pandemic crisis. The other breakthrough is that green policies – climate neutrality, biodiversity, “food-to-fork” - are central, explains Nicolas Berghmans at IDDRI. He summarises the plan, … [Read more...]
Why savings from the 2009 Buildings Refits stimuli were poor. Let’s do better this time
“Shovel ready” buildings renovations and refits can play an important part in a nation’s economic recovery programme. It gets money straight into the pockets of manual workers doing the refits, across the whole country, cuts the energy bills of all (both low and high income households), and accelerates efficiency gains for meeting climate targets. But first we need to learn lessons from the U.S. renovation stimuli of 2009, says Meredith Fowlie at … [Read more...]
