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...]
District Heating Roundtable: Policy across RED, EED and EPBD “must take account of conditions in all Member States”
Sara Stefanini provides a written summary of our panel discussion held on 10th February: District Heating under the "Fit for 55" package: challenges and opportunities. Under the “Fit for 55” package, the EC proposed several regulatory changes that, combined, are meant to decarbonise district heating in Europe. But are these options workable for all? The participants raise questions over the support for district heating, whether the multiple … [Read more...]
The greenest energy is the energy we don’t use
As COP26 comes to a close, Martin Rossen, Senior Vice President, Head of Group Communication and Sustainability at Danfoss reminds us in a powerfully persuasive way why the most direct route to net-zero is managing consumption. Inspired by a glaring omission by Bill Gates in his recent book, Rossen draws our attention to the futility of developing new tech if we don’t prioritise making use of readily available energy efficiency solutions. … [Read more...]
PET: a toolkit to make existing Coal plants more efficient
Many nations are struggling to phase out coal. Some, like China, are heavily dependent on it, and have more plants in the pipeline to ensure energy security and keep prices low. In other words, a lot of coal will remain in operation for the medium term. Given that, it makes sense to make them more efficient while they are in use. Daisy Chi at ECECP looks at a new set of tools – the Plant Efficiency Toolbox (PET) - that can analyse and optimise a … [Read more...]
Appliances and Equipment Efficiency Standards: energy savings rival total Wind & Solar generation
Don’t underestimate the effect of Energy Efficiency Standards and Labelling (EES&L) programmes for appliances and equipment, says the IEA. In other words, the gradual tightening of efficiency rules for things like refrigerators, ACs, TVs, washing machines, cookers, vending machines and other electronics. In the nine countries and regions measured (including the U.S., the EU and China), EES&L programmes reduced electricity consumption by … [Read more...]
Energy Efficiency solutions for electrification can help deliver the Transition – with the right policies
The latest climate assessment from the IPCC has underlined the urgency for the energy sector to make the transition quickly and effectively to net zero. The general drive towards mass electrification is a vast and complex undertaking but one that is made more manageable by the innovative development of energy efficient solutions for the built environment. Vesa Laisi, President at Danfoss Drives, outlines how cutting edge technologies are ready to … [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 China’s 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...]
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 FIRST” 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...]
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 “Efficiency First” - … [Read more...]
Five countries to become the field of behavioural experiments to encourage energy efficiency habits
The EU has ambitious targets for increasing energy efficiency and mitigating climate change, aiming that there are no net emissions of greenhouse gases by 2050. To achieve this and other targets, much effort and investment are focused on digital infrastructure (e.g., smart meters) that enables energy consumers to monitor and manage their energy usage more actively and efficiently. … [Read more...]
Guiding SMEs and national authorities through the energy transition by taking profit of multiple benefits and energy management approaches
Improving energy efficiency is the most cost-effective way to reduce energy-related emissions, improve economic competitiveness and increase energy security. In the European Union, several pieces of legislation aimed at guiding states and companies, regardless of their size, on ways to improve their energy efficiency: one of them is the Energy Efficiency Directive, establishing a common framework of measures and requirements with the goal to … [Read more...]
The importance of energy efficiency for a carbon neutral society
Energy efficiency has proven to be an effective solution for curbing carbon emissions from fossil fuels. But what if we imagined a future energy system without fossil fuels, will it still make sense to invest in energy efficiency or will it be sufficient to develop enough renewable energy to cover demand? A recent COGEN Europe study, conducted by consultancy Artelys, underscores the importance of energy efficiency for a cost-effective energy … [Read more...]
The nexus between data centres, efficiency and renewables: a role model for the energy transition
How much will electricity consumption from data centres grow from today’s 1% of the global total? 40-fold by 2030? Or a more manageable 5-fold? Or less? Sean Ratka and Francisco Boshell at IRENA try to answer this question by looking at the innovations being made by the tech industry to drive down power costs and emissions. The evidence is promising. Though data centre computing output jumped 6- fold between 2010 and 2018, their energy … [Read more...]
Developing nations: Efficiency is cheaper than Coal in Indonesia
Developing economies face a particularly big challenge in reducing emissions. Their economies are growing rapidly, industrialising and urbanising. Their populations surely deserve the same rewards of wealth that the rich countries – the historical and per capita big emitters - have experienced. Can they get there without all the emissions? Indonesia believes so, committing itself to 29% unconditional emissions reductions by 2030. Virginie … [Read more...]
From Buildings to Solar Thermal: using electric charge to vary insulating properties tenfold
The insulating properties of a material don’t normally vary. Applying an electric charge to a material can vary its electronic and magnetic qualities, but not its thermal conductivity, normally. David Chandler at MIT says now a team of researchers there have found a way to do it. Their “electrical heat valve” can increase the thermal conductivity of thin-film strontium cobalt oxide (SCO) on demand by running a charge through it after adding … [Read more...]
