LEDs are 90% more efficient than modern incandescent bulbs. Their rapid uptake has resulted in measurable cuts in energy demand and emissions. But their plummeting cost over the last ten years is also causing a “rebound effect” where people are using more and more LEDs, not least for outdoor lighting. Lucas Davis at the Haas School of Business believes we must embrace it, even if it’s counter to maximising energy savings. More and brighter … [Read more...]
Virtual Power Plants: efficiently networked households won’t need new expensive generation
Virtual Power Plants (VPPs) are the next new innovation that can change the landscape of the global energy transition in our favour, cheaply and fast, explain Liza Martin and Kevin Brehm at RMI. Essentially, they link and aggregate hundreds of thousands of households and businesses to manage their electrical devices. Their thermostats, EVs, appliances, batteries, and rooftop solar arrays are coordinated to ensure loads, charging and discharging … [Read more...]
The light bulb transition: when standards and subsidies promote sub-optimal technologies
This article is for those who want to understand the importance of timing: when is the right time to impose new standards and start/stop subsidies, to optimise the pathway to maximum efficiency? The light bulb transition of the last two decades is one of the successes of energy efficiency: from the old incandescents (15 lumens/watt) to halogen incandescents and CFLs, and then, finally, to LEDs (80 lumens/watt and prices falling 90% in ten years). … [Read more...]
Wellbeing peaks at just 75GJ per capita: a reachable target for poorer nations to rise to (and rich ones to fall to)
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...]
