The German Federal Association of Housing and Real Estate Companies (GdW) has claimed that money and effort spent on the nation’s buildings renovations have not worked. But Andreas RĂĽdinger at IDDRI has looked into the evidence and concluded that the opposite is the case. CO2 emissions from the residential sector in 2018 were 37% lower than in 1990. Though final energy consumption was broadly stable, that’s because efficiency gains were offset by … [Read more...]
New research into Catalysts can boost Hydrogen manufacture
Catalysts are materials used to enable and accelerate a chemical reaction. There is a long history of using them in industry to manufacture different hydrocarbons, ammonia, sulfuric acid, and the list goes on. By choosing your materials well and tinkering with the structure at the molecular level, the catalyst can greatly improve the efficiency of the conversion process. Glennda Chui at the SLAC National Accelerator Laboratory describes how their … [Read more...]
A new EU Gas Market must expose it to all clean energy solutions, not just gas-on-gas
Towards the end of this year the EC is expected to issue new proposals for gas legislation, a once in a decade market reform. Simon Skillings and Lisa Fischer at E3G highlight the big difference between the design of gas and electricity markets for Europe. The electricity market is growing, the gas market needs to shrink. The authors quote figures showing that the EU's 55% emissions reduction target for 2030 means natural gas use will reduce by … [Read more...]
Quantum Well solar cell sets new record for converting light to energy
There’s a new world-record for two-junction solar cells, converting 32.9% of sunlight into electricity. Although it’s only a small improvement on the previous record of 32.8% it uses a design that should lead to even greater performance. NREL, in collaboration with the University of New South Wales (Australia), has built a cell consisting of a series of more than 150 ultrathin layers of alternating semiconductors that create quantum wells which … [Read more...]
A beginner’s guide to European climate laws
Confused by the range of EU and national climate laws? The EU-ETS, the Effort-Sharing Regulation, the Renewable Energy Directive, the Energy Efficiency Directive, the Clean Energy for all Europeans Package, LULUCF, and more? Which are the important ones? Who exactly is making policy, and how? What are the real world effects? Julian Wettengel at Clean Energy Wire has asked experts to improve our understanding by answering a list of questions on … [Read more...]
Europe has enough Gas infrastructure. Why build more?
In early November a first vote is expected in the European Parliament on the Recovery & Resilience Facility’s €672.5bn budget. Esther Bollendorff at CAN Europe runs through the arguments against providing any funding for new gas infrastructure. She presents evidence to show that the EU is already oversupplied with gas import capacity, and all new fossil gas transmission projects have been rejected by the market since 2017. Solar and wind … [Read more...]
The Energy Charter Treaty needs updating, but remains a valuable tool for the transition
Last Thursday we published this critique of the Energy Charter Treaty (ECT). Created in the 1990s, the ECT was designed to protect cross-border energy investments from political risk. Critics now say it is being used to protect fossil fuel investments in a world committed to phasing them out. Today, Andrei Belyi of energy consulting firm Balesene OU and Adjunct Professor in Energy Law and Policy at the University of Eastern Finland, who was named … [Read more...]
Perovskites: the next generation of solar cells and lighting?
Enthusiasm about the discoveries being made about perovskite materials is spreading, explains Sam Stranks at the University of Cambridge. Perovskite solar cells hit 25.2% efficiency in 2019, not far off crystalline silicon cells at 26.7%. Research is suggesting that figure could rise higher still. Perovskite can be “tuned” to absorb particular frequencies of light, allowing different layers of perovskites to absorb different and therefore more … [Read more...]
Energy Charter Treaty: reform will only happen when energy ministers get involved
Negotiations are underway for the reform of the Energy Charter Treaty (ECT), an international trade agreement under fire from former Energy Charter executives, members of the European Parliament, and NGOs. Created at the end of the cold war, it was designed to protect cross-border energy investments – in a fossil fuel world – from political risk. Clare Taylor quotes the critics who say it no longer makes sense for the treaty to protect oil and … [Read more...]
We need Behaviour Change and “Life Efficiency”, because efficiency gains and clean energy will never be enough
Behaviour change – reducing emissions by changing how we live our lives - should be part of every government and think tank’s sustainable scenario, explains Schalk Cloete. That’s because impressive advances in energy efficiency and clean energy won’t be enough to contain the emissions of a world continuing with the essential task of lifting billions of people out of poverty. But this should not be seen as a problem, says Cloete, because behaviour … [Read more...]
Little progress decarbonising Industry. Renewables can be the answer
The decarbonisation of heavy industry is making little progress. There are two main reasons. Firstly, there are no easy technology wins. Efficiency and carbon capture have been the favoured options. But efficiency gains have their limits, and carbon capture is still proving very expensive. Secondly, governments don’t want their home industries to lose competitiveness incurring costs reducing emissions. Dolf Gielen and Paul Durrant at IRENA say a … [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 RĂĽdinger 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 MĂĽhlenhoff at CAN Europe … [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...]
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...]
