Edie Taylor, Rebecca Esau and John Matson at Rocky Mountain Institute explain how their report “Grid-Interactive Efficient Buildings Made Easy” identifies simple, low-cost steps that produce immediate cost, energy, and carbon savings. As utilities evolve their pricing structures to encourage users to avoid peak times, building managers must ready themselves with the controls that will allow them to buy electricity when it is cheapest. Demand … [Read more...]
When Electrification is cheaper than maintaining Gas infrastructure
The gas sector continuously faces major expenses to maintain and replace aging distribution systems. Non-Pipeline Alternatives (NPAs) are solutions that avoid the scale of these infrastructure costs by judiciously spending money on cutting future gas use instead. Given gas’s limited long-term future in a net-zero world, this makes sense. It’s not just about efficiency wins, explains Max Dupuy at RAP who summarises their research. Gas utilities … [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...]
IEA WEO 2021 message to COP26: 40% of clean energy goals will cut costs
The IEA’s latest World Energy Outlook was published on Wednesday. This year’s WEO-2021 is released earlier than usual to inform COP26 and, for the first time, is available for free to ensure the widest possible audience. Simon Evans at Carbon Brief offers his summary of the 386-page report, quoting relevant numbers and charts. He first points to the new scenario, Net-Zero Emissions by 2050 (NZE), as the IEA’s recognition that this is what … [Read more...]
Green hydrogen-based fuels pivotal in decarbonising Shipping by 2050
The international shipping sector’s emission levels are comparable to Germany’s. Like aviation and heavy transport, reaching net-zero will need renewable fuels – direct electrification won’t be sufficient. Existing fossil fuel engines allow for biofuel blends of up to 20% without any modifications, and 100% methanol engines are a proven technology. Making sufficient quantities of clean fuels - without consuming food crops – is the challenge. … [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-efficient and affordable housing will increase public support for the Green Deal
Energy poverty – the inability to afford basic household energy needs – affects up to one-third of U.S and European households. The energy transition can be part of the solution, says Clare Taylor. Targeted energy-efficient retrofits and newbuilds for low-income households will cut bills and improve living conditions. This will not only cut emissions, but get the beneficiaries behind wider climate change policies like the Green Deals in Europe … [Read more...]
We’re not costing energy correctly: reward clean energy optimisation, not maximum generation
Laura Sandys at Energy Systems Catapult says policy makers today are too focussed on rewarding clean energy generation, in other words supplying as much energy as possible. With that comes a focus on reducing the cost of the energy generated. But how about reducing demand? Demand optimisation should be equally rewarded: efficiency, non-generation demand management (even at the household level: think EVs and heat pumps), and any assets that … [Read more...]
Central and Eastern Europe’s buildings renovation plans fall far short of 55% emissions cuts
There are big decarbonisation gains to be had in a renovation wave in Central and Eastern Europe (CEE) precisely because their building stock is very energy-inefficient, explains Christophe Jost at CEE Bankwatch. But Bankwatch's report on eight national plans - Bulgaria, Czechia, Estonia, Hungary, Latvia, Poland, Romania and Slovakia – reveals weaknesses in scale, funding, strategy and policy. Many are planning to comply with only the former 40% … [Read more...]
‘Fit for 55’ should prioritise decarbonisation of laggards: buildings, transport, industry, agriculture
Today’s long-awaited "Fit for 55" legislative package from the European Commission will trigger intense and difficult negotiations that will last two years, says Nicolas Berghmans at IDDRI. Its scope is wide and inevitably interconnected. The twelve legislative proposals include adjustments to existing measures (renewable energy, energy efficiency, carbon market/EU ETS, energy taxation, climate effort sharing between Member States/ESR, land use … [Read more...]
UK: exposing the gap between ambitious climate laws and actual policies
Like many nations, the UK has big gaps between what is actually needed to reach net zero by 2050, what targets and ambitions have actually passed into law, and what policies are actually in place to comply with those laws. The UK’s climate watchdog, the Climate Change Committee (CCC), has issued two reports that measure the UK’s performance and makes recommendations, summarised here by Josh Gabbatiss at Carbon Brief. The first report focuses on … [Read more...]
Buildings Retrofits: inaccurate efficiency ratings are going to waste budget
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. What’s the best way to pay for it? The financial incentives governments put in place now will determine what investments get made, how cost-effectively it’s done, and who ultimately pays. Meredith Fowlie at UC Berkeley’s 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 it’s 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 Energy’s comprehensive plan, “A National Roadmap for Grid-Interactive Efficient Buildings”, 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 world’s 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 India’s challenges and which areas show the most potential for partnership with the EU. They focus on five themes: energy, … [Read more...]
