30+ nations now subsidise Heat Pumps because lifetime cost is cheaper than fossil boilers

January 10, 2023 by Josh Gabbatiss

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 “Announced Pledges Scenario” (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 APS’s heat pump growth … [Read more...]

Doubling clean energy investments from “natural” redirection of existing spend on infrastructure, buildings, fossils +more

December 19, 2022 by Stephen Peake

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...]

EU Energy Outlook to 2060: how will power prices and revenues develop for wind, solar, gas, hydrogen + more

December 6, 2022 by Alex Schmitt and Huangluolun Zhou

Alex Schmitt and Huangluolun Zhou at Energy Brainpool present a summary of their “EU Energy Outlook 2060”. Its scenarios map out how the European (EU 27, UK, Switzerland and Norway) energy system will change dramatically in the coming decades. Current geopolitical tensions are added to climate mitigation and an outdated power plant fleet as the main drivers of change at the EU and national levels. The in-depth modelling is trying to answer the … [Read more...]

Solar PV windows on highly glazed skyscrapers can cut energy by 40%+

November 30, 2022 by Wayne Hicks

Around a third of the world’s energy consumption and CO2 emissions come from buildings. Highly glazed skyscrapers and buildings may look beautiful and let in plenty of light, but waste a lot of energy due to the extra cooling needed in summer and heating in winter. Modern skyscrapers can have window-to-wall ratios of 70%+. But modern thermally efficient photovoltaic windows not only provide insulation but turn the absorbed light into power. Wayne … [Read more...]

Measuring the effect of radical protests on the public and the national agenda

November 11, 2022 by Colin Davis

Climate protest happen all over the world now. In some places they hit the news headlines hard because roads are blocked and cultural artefacts are vandalised by small numbers of protestors. These radical protestors are facing the “activist’s dilemma”: even though many of the public object to their methods, will the publicity help their cause? Colin Davis at the University of Bristol offers research that tries to measure the phenomenon. … [Read more...]

Tools to design energy systems resilient to natural disasters: from small villages to big cities

November 9, 2022 by Connor O'Neil and Moriah Petty

There is little doubt that emissions reduction will not be enough to cope with climate change. Adaptation will be essential too. Connor O’Neil and Moriah Petty at NREL describe how the National Renewable Energy Laboratory is developing free-to-use tools to help configure and create energy systems that are resilient to natural disasters. The tools have already been applied to small and large populations, ranging from a 500-person town to big … [Read more...]

Energy Security: what if the UK government had not “cut the green crap” from 2013

October 24, 2022 by Simon Evans

The UK provides an example of a government that cut back its green ambitions only to see its energy security suffer. In 2013, then-prime minister David Cameron told his ministers to “cut the green crap”. That led successive governments to downgrade home energy efficiency, requirements for new homes to be “zero carbon”, end subsidies for onshore wind and solar, and effectively ban onshore wind in England. What if the UK had stayed on its … [Read more...]

New U.S. ‘Buy Clean’ plan earmarks billions for low-carbon cement, steel and other building materials

September 27, 2022 by Victor Olgyay, Anish Tilak and Connor Usry

New guidance from the U.S. federal government, combined with historic Inflation Reduction Act investments, could turbocharge markets for low-carbon cement, steel, and other building materials. Victor Olgyay, Anish Tilak and Connor Usry at Rocky Mountain Institute explain how the new “Buy Clean” recommendations will mean the procurement of green building materials for federal building and transportation projects. That will lead to a boost in … [Read more...]

Buildings Renovation: city-wide comprehensive data management tools to transform each building

September 21, 2022 by Molly Rettig

In the U.S. the National Renewable Energy Laboratory (NREL) and Lawrence Berkeley National Laboratory have created a free-to-use (and develop) online data management tool – called SEED - that allows whole cities to collect details on thousands of buildings and use them to assess energy wastage at the single building level. Molly Rettig at NREL explains that hundreds of data points can be collected for each building. The tools, along with … [Read more...]

Grid Distribution Systems: access to usage data is uncovering the optimal design for future electrification

July 18, 2022 by Meredith Fowlie

The more efficient a distribution grid is, the less likely other potential supply bottlenecks (from lithium for batteries to trained electricians) will slow the transition to greater and greater electrification. State-of-the-art modelling of future grids is already happening, but the robust modelling of the distribution system is conspicuously missing because good data are notoriously hard to find, says Meredith Fowlie at UC Berkeley’s Energy … [Read more...]

Event summary: “45% RES by 2030: EU’s latest investment challenge to DSOs”

July 5, 2022 by Sara Stefanini

Sara Stefanini provides a written summary of our panel discussion held on Thursday June 30th 2022. It’s a full summary of the 90 minute discussion (including audience questions), but it begins conveniently with a summary of the highlights. Investment in and the modernisation of the electricity distribution grid is one the biggest challenges the EU has to overcome in the next decade. It’s a €400bn investment challenge by 2050 says Eurelectric, an … [Read more...]

Implementing Poland’s national Recovery and Resilience Plan

June 27, 2022 by Sonia Buchholtz

How should Poland implement its national Recovery and Resilience Plan (RRP)? Sonia Buchholtz at Forum Energii outlines some important answers. First, a deep analysis of the challenges and assessment of the solutions and reforms must start now. Buchholtz says though the directions set out in the RRP are correct, the details are out-of-date. Policy reforms and more ambitious targets are needed in all the main areas: energy efficiency and heating; … [Read more...]

4 ways to cut whole system electricity costs with flexible Demand Side Management

June 23, 2022 by Laura Sandys

Right now, energy system costs are driven by generation capacity, infrastructure upgrades, network reinforcements, curtailment and constraint payments, and imbalance costs. What’s missing is the investment in a raft of demand side management assets that are ready to go but are not part of the market, therefore not rewarded, and therefore not being invested in. Laura Sandys at Energy Systems Catapult, writing for WEF, explains why flexibility must … [Read more...]

EU Heat Pumps: warnings against “one size fits all” policies

May 31, 2022 by Helen Farrell

The EU is aiming for the installation of 50 million heat pumps by 2030, equating to annual growth of 16%, reaching one third of the total 150 million boiler installations in the bloc. Helen Farrell reviews these ambitious targets and the policies that are driving them, and turns to a report by RAP to identify the weaknesses in the plan and how it can be improved. The main danger is a ‘one size fits all’ approach. Different countries have … [Read more...]

Netherlands and China co-operate on Aquifer Thermal Energy Storage for heating and cooling

May 19, 2022 by Daisy Chi

Aquifer Thermal Energy Storage (ATES) accesses the stable temperature of groundwater to warm buildings in winter and cool them in summer. The solution uses much less power than conventional heating and cooling systems. As Daisy Chi at ECECP explains, ATES first took off in China in the 1960s but ran into problems with the required circulation of the groundwater. However, the technology has been developed and optimised in the Netherlands: of the … [Read more...]
