In May this year Spain reached a landmark day when it was powered 100% by renewables - solar, wind and hydroelectric power - from ten o'clock in the morning until seven o'clock in the evening. In four years the share of renewable energy generation rose from 37% to 50%, while non-renewables dropped from 62% to 49%. Its draft Law on Climate Change and Energy Transition targets 35% of renewable energy in final consumption by 2030 and 100% in the … [Read more...]
Europeâs grid bottlenecks are delaying its energy transition
***While you're here... REGISTER NOW for "REPowering the grid for Solar PV" with the Vice-President of Tauron, DG ENER C, Eurelectric and SolarPowerEurope - Online Wednesday September 20 from 11:00 to 12:15 CEST*** No amount of record sales and deployment in Europe of heat pumps, EVs, solar farms, wind turbines and all the rest will guarantee the region meeting its electrification targets if the grids arenât ready to integrate them. As … [Read more...]
Buildings Efficiency: cars have an âeco modeâ button. Why not our homes?
Households need the right tools to be able to take control of their real-time energy consumption, says Maximilian Auffhammer at the Energy Institute at Haas. Smart meters are just too crude. They donât tell you how much energy individual devices are using â fridges, ovens, heaters, EV chargers, TVs, lightbulbs, toasters, etc. You have to work it out yourself by switching devices on and off and seeing the difference. Auffhammer argues if you price … [Read more...]
Power to the people: citizen-centred Just Transitions challenge energy system centralisation
EU Member States need to phase-out coal and transform their carbon-intensive industries to make Europe climate-neutral. However, these should not be the only goals: transparency and justice must also accompany this path, argue Diana SĂŒsser at IEECP, Serafeim Michas at TEESlab and Ricardo Antonio GarcĂa Mira at the University of A Coruna. As Member States implement their territorial just transition plans, they must ensure they benefit affected … [Read more...]
Steel, Aluminium: 20% of emissions reductions target must come from Recycling. How?
Recycling is needed to achieve 20% of the emissions reductions targets for the steel and aluminium sectors. Itâs an integral part of the 1.5°C climate-aligned decarbonisation pathways in many metal sectors, explain Sravan Chalasani, Wenjuan Liu and Lachlan Wright at RMI. For aluminium products, the share that comes from post-consumer scrap needs to increase from 21% in 2020 to 46% by 2050. Recycling is already a reality, but reporting and … [Read more...]
Perovskite: abundant, cheap, printable solar cells demonstrated, ready to generate power
Laboratories around the world are racing to make printable perovskite solar cells, produced in abundance and so thin they can be wrapped around almost anything. Itâs a huge advantage over the typical silicon cell that is relatively big and fragile. And perovskite is much less expensive to produce. David Beynon at Swansea University describes research there that has demonstrated how a roll of plastic film can be loaded into a printing press to … [Read more...]
âRebound Effectâ: cheap LEDs mean more lights everywhere. But brighter homes, offices and public spaces are worth having
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 ârebound effectâ 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 itâs counter to maximising energy savings. More and brighter … [Read more...]
Will the computing power needed for self-driving cars create a carbon emissions problem akin to data centres?
Few predicted, in their early days, that the scale-up of data centres would result in them having a measurable impact on global energy consumption. Today they contribute 0.3% of global emissions. Thatâs a big enough number to put it on the global radar and for the IEA to be monitoring it. Will the wide scale take-up of autonomous vehicles have the same effect? Yes, explains Adam Zewe at MIT who describes new research from there. In summary, one … [Read more...]
Virtual Power Plants: efficiently networked households wonât 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...]
How to sell Heat Pumps to the public in Europe
In EU households, 62.8% of energy consumption is for space heating, and another 15.1% for water heating, mostly powered by fossil fuels. Heating and cooling is responsible for 52% of final energy demand in Europe. So, with REPowerEU, the EU has once again strengthened support for heat pumps to achieve energy independence and climate goals. Heat pump sales in Europe grew by an unprecedented 34% in 2021, thanks to a total 2.18m heat pump units … [Read more...]
30+ nations now subsidise Heat Pumps because lifetime cost is cheaper than fossil boilers
The global growth in heat pumps can deliver almost 40% of all possible emissions cuts from heating by 2030 (with most of the rest coming from efficiency, mainly insulation), says the IEA. This is according to their âAnnounced Pledges Scenarioâ (APS) which assumes that governments carry out all of the climate commitments they have made. Keeping buildings warm produces one-tenth of global energy-related CO2 emissions. So the APSâs heat pump growth … [Read more...]
Doubling clean energy investments from ânaturalâ redirection of existing spend on infrastructure, buildings, fossils +more
Annual investments in clean energy stand at $1.4tn, now greater than investments in fossil fuels ($1tn). But that needs to double by 2030. This steep climb will be made easier by the natural cycle of global investment, as well as the cost-benefits of abandoning fossil fuels for renewables and greater efficiencies, says Stephen Peake at The Open University. Each year, around a quarter of our GDP is anyway spent on new machinery, buildings and … [Read more...]
Distribution Grid Digitalisation – benefits, policy, cost & funding
About a third of European grids are over 40 years old. A rapid physical overhaul would be impossible, so the addition of a layer of digital technologies is the key to preparing them for the distributed and intermittent generation from renewable sources, the increased electricity demand from transportation, heat pumps and other sectors, and for ensuring energy efficiency at all levels. Itâs why the EC expects about âŹ584bn of investment in Europeâs … [Read more...]
Comparing the efficiency and progress of the 5 leading Solar PV cell technologies
NRELâs âBest Research-Cell Efficiency Chartâ allows researchers to easily compare the performance of specific PV technologies, stretching back 50 years. Itâs regularly updated and is free to use, explains Wayne Hicks and Harrison Dreves at NREL. A new âinteractiveâ version is now available. The focus is on crystalline silicon cells, single-junction gallium arsenide cells, multijunction cells, thin films, and emerging PV. For example, you can … [Read more...]
