The International Energy Agency recently hosted two energy efficiency events related to Japan’s presidency of the G20.

The third workshop of the G20 Energy End-Use Data and Energy Efficiency Metrics initiative took place on 21 and 22 November at the IEA headquarters in Paris under the title “Uncovering the role of digitalisation for energy efficiency indicators.”

This initiative – co-led by the IEA and the French government through its national energy efficiency agency (ADEME) – aims to bring professionals together to develop international cooperation on energy end-use data and energy efficiency metrics by sharing best practices and experiences on the topic. This year, it included a special focus on the role of new digital technologies.

The workshop drew wide interest and engagement, gathering 30 representatives from 14 countries and 4 international organisations around the table. Their discussions will feed into a paper under the framework of the initiative that will compile good examples of traditional data collection methodologies across sectors and the development of new technologies and digitalisation for end-use data collection.

The presentations are available on the workshop page. More information on the IEA’s work on energy efficiency data is available here.

The two-day event was preceded by a half-day workshop on 20 November on global energy efficiency benchmarking. Aimed at government and industry experts, it focused on the specific processes and challenges associated with collecting data and benchmarking energy efficiency in energy-intensive industry sub-sectors, specifically iron and steel.

The IEA is eager to continue engaging with countries in the G20 and beyond on efficiency data and benchmarking activities, as well as discussing development priorities and the latest advances around these topics.

IRENA and the ESA Agree to Advance Energy Transition in Space Activities

Published

on

The International Renewable Energy Agency (IRENA) and the European Space Agency (ESA) signed a Memorandum of Understanding (MoU) today to advance the global energy transition through space-based services and products. The new partnership was signed by the two Director-Generals Francesco La Camera and Josef Aschbacher in pursuit of the common goal to ensure sustainable long-term socio-economic development within planetary boundaries.

Data and images from satellites can play a significant role to help countries better assess the geographical potential of renewables, identify the best locations for projects, forecast weather patterns and support long-term planning of new renewable generation capacity and infrastructure.

Francesco la Camera, IRENA’s Director-General said: “Today’s partnership opens a new avenue of cooperation to advance the international cooperation on energy transition globally. While an energy system underpinned by renewables is key to decarbonising our world in line with climate goals, renewables bring socioeconomic benefits with economic opportunity and social equity at its heart. By combining IRENA’s knowledge on energy transition with ESA’s space research and technology, we can accelerate the low-carbon energy transition and promote sustainable growth.”

Under the agreement, IRENA and ESA will make use of space assets and data to improve renewable generation site location, access to energy, electrification modelling, renewable resource mapping and smart grid planning. Urban energy system planning with focus on local renewables may also benefit from satellite data while enhancing system resilience.

Making use of digital technologies including 5G and combining for example satellite imagery with artificial intelligence and big data provide a unique opportunity to enable a wider space economy and support energy transitions across the world.

IRENA Outlines Action Agenda on Offshore Renewables for G20

Published

on

Boosting offshore renewables will accelerate the energy transition and allow G20 countries to build a resilient and sustainable energy system, a new report by the International Renewable Energy Agency (IRENA) finds. Offshore Renewables: An Action Agenda for Deployment actively contributes to the G20 agenda by identifying actions which support the commercialisation of offshore technologies such as wind, wave, tidal, ocean thermal and floating PV in pursuit of extending their deployment worldwide. The report was launched by IRENA’s Director-General Francesco La Camera during the meeting of G20 Environment, Climate and Energy Ministers in Naples.

“Offshore renewables have the potential to meet more than twenty times of today’s global power demand”, said Francesco La Camera, Director-General of IRENA. “Particularly offshore renewables constitute a critical pillar for decarbonising energy systems and fostering a global blue economy. I congratulate the G20 Presidency for their forward-looking decision to integrate offshore renewables in the G20 agenda. IRENA is pleased to support the G20 Offshore Renewables Action Agenda with our energy transition expertise and valuable input from our global membership.”

To put the world on a climate-safe pathway, IRENA’s 1.5°C scenario foresees a massive growth of offshore wind,  ocean energy and floating photovoltaic in the coming decades. Offshore wind for example would increase from 34 gigawatts (GW) today to 380 GW by 2030 and more than 2,000 GW by 2050. Ocean energy would represent additional 350 GW of offshore renewable generation capacity by 2050.

Today’s report includes 50 concrete actions that G20 countries could take while defining their national strategies for offshore renewables. Suggested actions include the strengthening of oceans governance in line with UN Law of the Sea, the integration of offshore renewables in national marine spatial planning and early planning for infrastructure like underwater cables and grids. Policy frameworks, international cooperation and investment in R&D are key recommendations to drive offshore globally. The report recommends to promote financing for offshore within the “Finance Track” of the G20.

Offshore renewables have the potential to greatly contribute to SDG 14 on the sustainably use of oceans while boosting blue economy activities such fishery, shipping and tourism. A blue economy fuelled by offshore renewables would help islands and countries with coastal areas to meet their national goals aligned with the Paris Agreement and 2030 Sustainable Development Agenda.

The G20 is well placed to foster offshore renewables. Members account for the vast majority of global economic activity and trade and are home to over three-quarters of total offshore renewable installed capacity to date. 99.3% of total offshore wind capacity and nearly all installed ocean energy capacity globally can be found in G20 countries.

Today’s report was prepared by IRENA on the request and to the Italian Presidency of the G20. It benefited from the input of the G20 Working Group on Energy and insights by IRENA’s global membership gained under the Agency’s Collaborative Framework on Offshore Renewables.

Empowering “Smart Cities” toward net zero emissions

Published

WAN

The world’s cities can play a central role to accelerate progress towards clean, low-carbon, resilient and inclusive energy systems. This idea is recognized by climate and energy ministers from G20 nations who will meet under the presidency of Italy in Naples to focus on steps that national governments can take to support urban areas to deploy solutions and technologies to reduce emissions.

New technologies and increased connectivity, as well as the sheer scale of the world’s metropolises, are opening up massive opportunities to optimise urban planning, improve services and extend access, while at the same time creating revenue streams, jobs and business ventures. In this context, the International Energy Agency developed a report at the request of the Italian G20 presidency to showcase the opportunities and challenges facing cities, and the actions that can be taken to support progress.

The IEA’s Empowering Cities for a Net Zero Future builds on extensive consultations with over 125 leading experts and organisations, and presents case studies from 100 cities in 40 countries. The examples illustrate the wide range of opportunities and solutions that can help city-level authorities make full use of efficient and smart energy systems.

At the same time, urban agglomerations are incubators for cutting-edge technologies, and their density and size offer economies of scale that can cut the cost of infrastructure and innovation. This mix of factors puts cities at the leading edge to come up with creative solutions to climate and energy challenges.

And with growing urbanisation trends, the central role of cities will keep increasing. Cities today account for more than 50% of the planet’s population, 80% of its economic output, two-thirds of global energy consumption and more than 70% of annual global carbon emissions. By 2050, more than 70% of the world’s population will live in cities, resulting in a massive demand growth for urban energy infrastructure.

From smart streetlamps to self-cooling buildings to smart electric car chargers, investing in city-level action can provide the biggest carbon-mitigation return on investment and accelerate inclusive clean energy transitions.

The new report contains a set of high-level recommendations to accelerate energy transitions and leverage the full potential of cities to reduce emissions thanks to digitalisation.

By 2024, an anticipated 83 billion connected devices and sensors will be creating large, diverse datasets on a wide range of topics, such as energy consumption, air quality, and traffic patterns. Next-generation energy systems can leverage the data from these connected buildings, appliances and transportation systems to reduce energy consumption, improve grid stability and better manage city services. 

For example, digital simulations can show how different designs, technologies and equipment affect energy demand pathways and associated costs. The LA100 study, conducted by the U.S. National Renewable Energy Laboratory, points the way towards achieving a 100% renewables-supplied city by 2045. The study simulates thousands of buildings, using aerial scans, customer adoption models as well as utility planning tools to ensure power system stability, and estimates that these measures would avoid between USD 472 million and USD 1.55 billion in distribution network investments.

The electricity consumed in street lighting globally is equivalent to Germany’s total annual electricity consumption, and can constitute up to 65% of municipal electricity budgets. Yet only 3% of the globe’s 320 million street lighting poles are smart enabled, even though smart street lighting can reduce electricity use by up to 80% by adjusting output based on ambient light levels and weather. Smart street lamps can also monitor traffic, pedestrian crossings, and noise and air pollution, as well as incorporate electric car chargers and cell phone infrastructure.

India, under its National Streetlighting Programme, has reduced peak energy demand by more than 1000 MW thanks to 10 million smart LED streetlights. Digitalisation can also help improve maintenance. In Italy, an app developed by Enel X allows citizens to report street lighting faults using their smartphones.

To reduce congestion and greenhouse gas emissions, Jakarta’s Smart City initiative integrated public transport management and payment systems to help plan a more reliable, safe and affordable rapid bus transit system. Under PT JakLingko Indonesia, this comprehensive integration process increased the number of Transjakarta commuters from about 400 000 per day in December 2017 to just over 1 million per day in February 2020.

Vancouver, Canada, now requires every residential parking space in new developments to feature electricity outlets to charge electric vehicles. Meanwhile, digitalisation can shift around 60% of the generation capacity needed to charge these vehicles away from peak demand times. Smart traffic management systems can reduce congestion by 8%.

As economies recover from the Covid-19 pandemic, CO2 emissions are rebounding rapidly. The increase in global energy-related CO2 in 2021 could be the second largest in recorded history. Cities are the globe’s economic engine, and the solutions they seek can transform the energy landscape by creating new synergies to reduce emissions, improve energy efficiency, enhance resilience and provide a cleaner prosperous future for us all. Strong international cooperation and collaboration can play a crucial role in this, notably through emerging knowledge-sharing networks that span cities and countries.
