Buildings renovations are going to be expensive, and complicated to roll out. Accurately predicting how much energy a building actually wastes will make that process easier and cheaper. EPC ratings are used to categorise the energy efficiency of homes. But Freya Wise at The Open University quotes research in Europe, along with her own investigations in the UK, to show that a lot of older buildings waste less energy than the standard estimates are … [Read more...]
Financial incentives for Grid Modernisation: the problem with guaranteed returns on investment
Grid modernisation is going to be very expensive. Whatâs the best way to pay for it? The financial incentives governments put in place now will determine what investments get made, how cost-effectively itâs done, and who ultimately pays. Meredith Fowlie at UC Berkeleyâs Energy Institute at Haas explains that a common method is for a government to give some sort of guaranteed return on investment for the new asset. But itâs far from ideal. … [Read more...]
U.S. DoE: National Roadmap for Grid-Interactive Energy-Efficient Buildings
Buildings account for more than 70% of U.S. electricity use and one-third of economy-wide CO2 emissions. Andrew Satchwell at the Lawrence Berkeley National Laboratory presents the U.S. Department of Energyâs comprehensive plan, âA National Roadmap for Grid-Interactive Efficient Buildingsâ, that could deliver up to $200bn in savings to the U.S. power system and cut CO2 emissions by 80m tons per year by 2030 (6% of total power sector emissions). … [Read more...]
EU-India cooperation: how to tap the large potential for climate action
India is the worldâs fifth largest economy, the second most populous, and over the next few decades is expected to see energy demand grow more than any other country. Ritu Ahuja and Mekhala Sastry at TERI, Abhishek Kaushik at the Centre for Global Environment Research, and Alexandra Deprez and Lola Vallejo at IDDRI look at Indiaâs challenges and which areas show the most potential for partnership with the EU. They focus on five themes: energy, … [Read more...]
Bidenâs Leaders Summit: turning climate commitments into solutions
President Biden's Leaders Summit on Climate last month helped focus minds on making firm commitments to reducing global emissions. As we all know, targets are one thing, credible and realistic solutions are another. To understand the challenge better, Dolf Gielen, Ricardo Gorini and Gayathri Prakash at IRENA break down into themes those areas that need much more effort and, if dealt with successfully, can get us to net zero by 2050: structural … [Read more...]
“China and Europe – Energy Efficiency, the foundation of our net-zero future” [EVENT highlights and VIDEO]
We present the videos of the third of our three, 4-session workshops on the opportunities for European energy solutions providers to take part in Chinaâs energy transition, held on April 13th and 14th 2021. In this workshop the theme was efficiency, with special reference to finance, buildings, heating and cooling, and smart solutions. Both regions need to go beyond the efficiency "easy wins" so we take a close look at what Europe can offer as … [Read more...]
Plastic Solar Cells: OPV power conversion efficiency now reaches 18%
Donât just think plastics are insulators. Two Nobel prizes were won by showing they can be semiconductors. That celebrated research opened the door to polymer-based solar cells. They are made in a lab from common elements, using processes established decades ago for ordinary household items like plastic wrap. A design strategy breakthrough led by NREL has now created an organic photovoltaic (OPV) solar cell with a record-breaking 18.07% power … [Read more...]
Buildings Efficiency in China, and what EU partners should know
To set up our upcoming online event (April 13th & 14th) "China: Carbon Neutral by 2060 -EFFICIENCY FIRSTâ we look at how Buildings Efficiency is being tackled by Energy Management Contracting (EMC), when an ESCO (energy service company) provides energy retrofit services and gets paid for the future energy savings. The up-front investment cost is recouped over the multi-year lifetime of the service contract by taking a cut of the genuine … [Read more...]
Energy efficiency is the âfirst fuelâ, making decarbonisation easier for all other sectors
To set up our upcoming online event âChina: Carbon Neutral by 2060 -EFFICIENCY FIRSTâ we look at the profound importance of efficiency to the global energy transition. Energy efficiency is the âfirst fuelâ, meaning success here will make the decarbonisation of all the other sectors and technologies easier, faster and cheaper. Basically, use and waste less energy. Alyssa Fischer at the IEA starts by noting that their Sustainable Development … [Read more...]
Five practical steps Oil & Gas can take to accelerate their energy transition
The Oil & Gas sector has a role to play in the energy transition, and not just by winding down operations. Thatâs because they will, by most projections, continue to be a major part of the energy mix through to 2050. But their activities must transition too, explain Bart Valkhof, Pedro Gabriel Gomez Pensado and Wan Sayuti at the World Economic Forum. The sector must therefore work out which strategies and investments can produce the lowest … [Read more...]
EU Recovery funds: where is the support for District Heating?
District Heating is an efficient way to heat homes, particularly in a country like Latvia where 58% of its primary energy consumption is used for heating. But SelÄ«na VancÄne at Riga City Council is very concerned that the draft EU Recovery plans do not include any support under the climate goals for district heating projects. Perhaps itâs because of a blind spot: most of Europe is prioritising individual heating units powered by electricity. … [Read more...]
EU Buildings Renovations: get ready for minimum energy performance standards (MEPS)
To meet Europeâs 2030 climate targets the buildings sector must cut its emissions by 60%. That means annual renovations need to jump by an order of magnitude; at the moment itâs crawling at 1% per year. Worse, standard renovations save very little energy, just 9% in homes and 16% in commercial buildings. Itâs the deep renovations that cut energy by 60% or more, but thatâs only happening to under 0.3% of the stock. Louise Sunderland at RAP … [Read more...]
Wave Energy: how variable geometry designs can raise conversion efficiency
Wave energy is another renewable technology waiting to break through. One main challenge is that about 35%â50% of WEC (wave energy converter) costs come from the device structure alone. Researchers at NREL are experimenting with variable geometry, changing the shape of the WEC so that in more energetic seas the structural loads are controlled. In turbulent seas the excess load can easily be shed, while when the seas are quiet the maximum energy … [Read more...]
Wide variations in National Energy and Climate Plans: how can the EU seriously budget for emissions reductions?
The EU has big and growing ambitions for emissions reductions by 2030: down 40% below 1990 levels, increasing the share of renewables to 32% of final energy consumption and improving energy efficiency by 32.5% above business-as-usual. These targets will be further revised as the more ambitious goal of cutting emissions by 55% by 2030 becomes legally binding. This means the EU as well as individual nations must estimate the cost of meeting these … [Read more...]
Policy-makers still undervalue Energy Efficiency as a grid resource
Supply-side solutions to grid stability are few in number, and expensive. More baseload generation, electricity networks, capacity markets that pay power plants all year round to be available for dispatch during a few peak hours. Demand-side solutions are usually smaller, and multitudinous: building fabric improvements, equipment upgrades, customer behaviour interventions, and more. So, for grid stability, the principle of âEfficiency Firstâ - … [Read more...]
