The International Energy Agency’s latest and most comprehensive assessment of clean energy transition finds that the vast majority of technologies and sectors are failing to keep pace with long-term goals. Of the 45 energy technologies and sectors assessed in the IEA’s latest Tracking Clean Energy Progress (TCEP), only 7 are on track with the IEA’s Sustainable Development Scenario (SDS). The SDS represents a pathway to reach the goals of the Paris Agreement on climate change, deliver universal energy access and significantly reduce air pollution.

These latest findings follow an IEA assessment published in March showing that energy-related CO2 emissions worldwide rose by 1.7% in 2018 to a historic high of 33 billion tonnes.

Some clean energy technologies showed major progress last year, according to the new TCEP analysis. Energy storage is now “on track” as new installations doubled, led by Korea, China, the United States and Germany. Electric vehicles had another record year, with global sales hitting 2 million in 2018. China accounted for more than half of total sales.

Solar PV remains on track with a 31% increase in generation – representing the largest absolute growth in generation among renewable sources. But annual capacity additions of solar PV and renewable power as a whole levelled off in 2018, raising concerns about meeting long-term climate goals.

This year’s analysis expands coverage to include flaring and methane emissions from oil and gas operations, which are responsible for around 7% of the energy sector’s greenhouse gas emissions worldwide. Despite some positive developments over the past year, current technology deployment rates, policy ambition and industry efforts are still falling well short.

The buildings sector also remains off track, with emissions rising again in 2018 to an all-time high. This was the result of several factors, including extreme weather that raised energy demand for heating and cooling. Another concerning development was the slowdown in fuel economy improvements around the world as car buyers continued to purchase bigger vehicles.

Given the urgency and scale of actions needed for clean energy transitions around the world, this year’s TCEP features much greater emphasis on recommended actions for governments, industry and other key actors in the global energy system. The analysis also includes in-depth analysis on how to address more than 100 key innovation gaps across all sectors and technologies.

TCEP provides a comprehensive, rigorous and up-to-date expert analysis of clean energy transitions across a full range of technologies and sectors. It draws on the IEA’s unique understanding of markets, modelling and energy statistics to track and assess progress on technology deployment and performance, investment, policy, and innovation. It also draws on the IEA’s extensive global technology network, totalling 6,000 researchers across nearly 40 Technology Collaboration Programmes.

TCEP is part of the IEA’s broader efforts on tracking energy transitions and key indicators to help inform decision makers on where to focus innovation, investment and policy attention to achieve climate and sustainable development goals.

    DISTRIBUTOR OF 100% CLEAN ENERGY

    Feníe Energía, the installation agent’s company, is the independent energy distributor that has demonstrated the highest level of growth in Spain. Its model makes it stand out from other companies as it benefits from a network of energy agents who assess and understand the needs of the customer and who furthermore, are shareholders. Our mission is for customers to make savings through the work and experience of the network of energy agents, which is Feníe Energía’s own commercial network. They are the ones that maintain a direct contact with customers, providing them with personal assessment, which implies a close relationship and proximity with the customer and what they call “management through trust”. As a distributor of 100% clean energy committed to the environment, in addition to electricity and gas, the company offers energy saving, self-consumption, mobility and energy management services.

    The buildings in which Europeans sleep, eat, shop, learn and work, house a great opportunity for energy saving and emissions reduction, particularly in the so-called technical systems: heating, DHW, cooling, ventilation and lighting. A recent study by energy consultancy Ecofys, sponsored by Danfoss, shows the energy saving that can be achieved by improving energy management in Europe’s buildings. This hitherto under-exploited potential is calculated to save €67bn on the annual energy bill of European citizens by 2030, while reducing CO2 emissions by 156 Mt. Documents have been published as part of the study that focus on different types of buildings. This article sets out the main conclusions of the study in the case of supermarkets, along with some of the more recent success stories from Danfoss in this sector on the Iberian Peninsula.

    Buildings allocated to supermarkets in Europe occupy an approximate surface area of 115 million square metres. Part of the study included an assessment of the energy saving potential of a sample supermarket with a surface area of 1,025 m2 and a total energy consumption of 181 kWh/m2a. This sample building is equipped with a gas condensing boiler for heating (with energy recovery for the refrigeration system); mechanical ventilation systems with no heat recovery; a refrigeration and air conditioning system by means of compression chillers; and a direct and indirect lighting system via fluorescent tubes.

     

    Improvements to the technical systems in this sample supermarket reveal the possibility of achieving a 45% saving in energy, which translates into just over 8,000 €/year, with an investment of some €36,000 that would be amortised in around 4.5 years. Read more…

    To date, building certification standards have not taken into account the energy saving potential of every aspect relating to the automation and control of buildings’ energy consumption. The eu.bac methodology, based on currently applicable standards (EN 15232, DIN V 18599) and scientifically validated by the Technical University of Dresden (Germany), aims to fill this void. This article describes the success story of the hotel Pago del Olivo, demonstrating the savings potential that can be achieved in a building designed for hotel use following the application of this methodology.

    Opened in January 2011, the hotel Pago del Olivo is a three-star establishment located in Simancas (Valladolid), offering 36 rooms, a 70 m2 lounge as well as indoor and outdoor car parking. Sedical undertook the certification, for which end an authorised inspector visited the establishment. Using a standard questionnaire, filled out by the owner, the person responsible for the building or the systems integrator, the authorised inspector checked to see if the stated functions were available and active.

     

    Following a study of the documentation and the site inspection to check on the existence and type of control equipment, as well as ensuring it was working properly, the audit produced a score of 22 points with an E rating under the eu.bac system. The calculation tool also indicated that the installation had a margin for improvement of 78 points. Read more…

    The buildings where you sleep, eat, shop, learn and work hold a huge opportunity: EUR 67 billion savings on energy bills for EU citizens annually in 2030, and a reduction in emissions of 156 Mt. CO2. These groundbreaking results are presented in a study, released by energy consultancy Ecofys, a Navigant Company. The report, initiated by Danfoss, provides proof of the huge energy savings potential that can be obtained from better management of energy flows inside European buildings. A potential that has been insufficiently exploited.

    We spend most of our time in buildings. It is, therefore, no surprise that buildings consume a large amount of energy. But 75% of our housing stock is energy-inefficient. Most of the vast amounts of energy is used to maintain the right temperature and air quality in heating, cooling and ventilation systems – collectively known as a technical building system.

     

    When these systems are not working optimally, energy goes to waste, they cost money and cause damage to the health and the environment. But we have the technologies to prevent this. Consistent improvements could help reduce energy waste, cut costs and make our buildings better places to be. The report assesses a scenario where buildings are renovated in the period until 2030. The energy consumption in these buildings could be reduced by around 30% through upgrades to heating, cooling, ventilation, lighting and hot water systems.

    We have all the technologies at hand to make our buildings smart. Taking the findings of the new Ecofys study into account, we see that optimizing the control of energy flows inside buildings and leveraging new technologies, like digitalization, could deliver around 15% of the EU 2030 energy efficiency target. Political support is needed to remove barriers and accelerate the speed and scale of the investments. This will send the right market signals for innovation, jobs and sustainable growth,” says Andre Borouchaki, Senior Vice President and CTO, Danfoss.

    According to calculations by Danfoss based on the World Resources Institute’s report, Accelerating Building Efficiency, from 2016, reaching 15% of the EU 2030 energy efficiency target will create 300,000 new jobs.

    The EUR 67 billion we can save annually on a full application of high performance technical building systems, mostly from not importing gas from third countries, could be invested in Europe instead, providing additional comfort and well-being for EU citizens.

    The only way to significantly improve building energy efficiency is to focus on existing buildings. Nine out of ten of existing buildings in the EU will be occupied by 2050. Renovation of our building stock is more affordable than many currently believe. The investment cost for basic improvements of controls of energy flows inside buildings is low, and the payback time is two years to get the basics right.

    The consistent optimization of the energy use of technical building systems in existing buildings across Europe should start now,” says Dr. Andreas Hermelink, Associate Director at Ecofys, a Navigant Company. “We are talking about no-regret measures that can quickly deliver very significant reductions of energy consumption, energy bills and CO2 emissions. The revision of the Energy Performance of Buildings Directive should give a strong and effective push for unleashing the full cost-effective savings potential of technical building systems.

    The 29th edition of the Gas Forum which took place in Madrid last 6 and 7 October at the CNMC’s premises as part of the presidency of the European Union, discussed the need to assess the future of natural gas in Europe (up until 2030 and as from that date). Specifically, participants highlighted the need to start strategic discussions in the gas sector that address aspects including the impact of decarbonisation policies, developments in the electricity sector, the benefits of energy saving and the use of new technologies. Below is a summary of the main conclusions of this edition as contained in a document available on the European Commission website.

    The Forum saw intensive debate on the issues regarding the foundations of natural gas supply and demand in the EU, both for the pre- and the post-2030 periods. Despite differences in modelling and assessments, the Forum agreed on the need to start strategic discussions on this matter. This discussion should be based on an in-depth assessment of the possible drivers and consequences of the respective scenarios on all levels of the EU gas sector value chain. These include the evolution of decarbonisation policies, developments in the electricity sector, improvements in energy efficiency, new technologies for example in the field of gas-to-power or green gas, and market developments.

     

    The Forum welcomed the overall improvements in the EU market operation – as reflected in the ACER Market Monitoring Report 2015 which includes a health check on the wholesale gas market – but noted that in certain markets, this remains unsatisfactory. The Forum also took note of initiatives, such as CESEC and the implementation of the general Network Code, to address these shortcomings. The Forum confirmed the potential of LNG and storage in the context of diversification and the security of the supply, urging further scrutiny on a case-by-case basis to ensure the most efficient use of such an infrastructure.

    The lighting solutions from Schréder Socelec have achieved a high level of quality in the lighting renovation of the premises of Cañamás Hnos., a company specialising in the cultivation and processing of citrus fruits, by providing a high performance LED alternative at minimal cost to the owners. Thanks to the solution adopted, a saving of around 75% has been achieved compared to the total consumption of the previous lighting system that comprised old floodlights/bell lamps. In addition to saving energy, both security and comfort have been enhanced at premises that have a considerable movement of workers and vehicles.

    Cañamás Hnos., in collaboration with Schréder Socelec, has renovated the lighting at its fruit and vegetable plants located in Oliva and in L’Alcudia (Valencia) where the citrus fruit grown on its land is handled and processed.

    Schréder Socelec undertook a detailed study of the different industrial areas in which the employees work with different types of machines that create potentially dangerous situations. These areas require lighting levels that are adapted to that specific environment to guarantee the safety of the workers. Moreover, the luminaires have had to adapt to special conditions (flameproof, extreme temperature-proof, explosionproof, etc.).Read more…

    As governments focus on implementing their commitments to save energy and reduce carbon emissions under the recently ratified Paris agreement, a new report from the International Energy Agency (IEA) highlights the progress made by energy efficiency policies around the world over the past year, particularly in China and other emerging economies.

    The role of energy efficiency in the global energy transition is examined in the IEA’s Energy Efficiency Market Report 2016, which finds that its importance cannot be overstated. Simply put, there are no realistic or affordable energy and climate change policy without a sizeable and vigorous energy efficiency component.

     

    Energy intensity — the amount of energy used per unit of GDP — improved by 1.8% percent last year, meaning the global economy needed less energy to grow. The improvement exceeded the 1.5% gain of 2014, and was triple the average rate seen over the past decade. What’s more, last year’s gains were achieved in spite of lower energy prices, which generally dampen the enthusiasm for energy savings.

    However, the report also shows that while much has been accomplished, global progress is still too slow. Global energy intensity improvements need to reach at least 2.6% per year to put the world on a sustained pathway for a decarbonised energy system.

    Energy efficiency policies aim to deliver the maximum amount of social and economic benefit from the energy we use. For that reason, they are essential tools for government action that have a real impact on global energy demand. For instance, car fuel economy standards around the world saved 2.3 million barrels a day of oil last year, or 2.5% of the global oil supply.

    Efficiency standards now cover 30% of energy use globally, up from 11% in 2000. IEA countries saved USD 540 billion in energy expenditure in 2015 as a result of energy efficiency improvements since 2000.

    One country in particular showed significant progress, China, where energy intensity improved by 5.6%. That was up from an annual rate of 3.1% over the previous decade, according to the report. Primary energy demand in China grew by just 0.9% in 2015, its lowest rate since 1997, while the economy grew by 6.9%. Without this contribution, the global energy intensity improvements would have been just 1.4% in 2015.

    The IEA has identified energy efficiency as a critical “fuel” in the transition to a low-carbon economy. Its analysis has shown that over a third of all emissions reductions needed to reach climate goals by 2040 must come from energy efficiency policies. Efficiency gains in the IEA’s member countries were large enough to power Japan in 2015 making efficiency a critical component of a secure, sustainable energy system.

    The report demonstrates the central role of government policy in driving energy efficiency. It shows that policies must be strengthened and expanded to boost the potential gains from energy efficiency.

    Since 2013, the Hospital de Manises, together with its associated healthcare centres and special units, have managed to bring down their energy consumption by 16% as well as achieving a 50% reduction in CO2 emissions. These figures go beyond the initial objectives forecast for 2015, given that the target was to reduce the 2015 carbon footprint by 20% by means of measures including: saving energy on the consumption of gas and electricity, the green purchase of renewable energy sources of 100% of the electricity consumed in the area, a reduction in the number of business trips and the acquisition of hybrid vehicles for home care.

    The centre has obtained this good result thanks to the launch of an ambitious sustainable management programme that has been implemented alongside other actions including replacing the lighting system in the hospital and primary care centres with LED technology that consume less than conventional systems.

    A high level of performance has also been achieved from the centre’s solar thermal plant to reduce the consumption of natural gas in domestic hot water generation. The optimisation of the solar PV panels has been another savings factor as they are able to supply the consumption equivalent to all the lighting for the hospital’s main foyer over the course of 14 hours a day.

    The LED is a light source with a future full of possibilities. This technology has experienced an exceptional evolution in recent years, surpassing in efficiency terms the most efficient lamps that exist in the market based on other conventional technologies. The possibilities of this technology in combination with smart control systems offer unique regulation and immediate response features, essential to achieving a significant energy saving, in addition to prolonging the life of the LED and, as such, considerably reducing maintenance costs. These energy savings can even amount to over 85%.

    For more than five years, the technicians at Leycolan have been working to equip outdoor and industrial lighting systems, in other words, the lighting of large spaces, with intelligence and to make them more efficient. Leycolan’s solutions bring together LED technology based on COB LED (Chip-on-Board) that considerably facilitates maintenance tasks and the job of replacing lighting components, with Power Line Communication (PLC) technology.

    In this way, the existing light cabling infrastructures can be made use of to communicate with the lighting points via a physical medium, which is much harder to sabotage or be interfered with by external agents. In addition, they can be integrated into other IP services, such as peripheral-type cameras, information panels, WiFi relays, IP speakers, etc., with the system providing a communication bridge for all these applications that can subsequently be centralised or redirected as necessary via web-based communication.
