Energy Efficiency 2018
…current technology. This delayed action on energy efficiency ends up locking in inefficiencies that mean much stronger action needs to be taken in the future. 2.2 million barrels of oil per day If all countries had adopted the best passenger fuel economy standards. 16% of industry electricity use If all countries had adopted the strongest electric motor standards. $20 billion If everyone had purchased the top 10% most efficient refrigerators. The Efficient World Scenario So what will the world look like if between now and 2040 countries implemented all the economically viable energy efficiency potential that is available? The…

Clean Energy Transitions Programme 2023
Annual report 2023 The Clean Energy Transitions Programme (CETP) is the IEA’s flagship initiative for accelerating progress toward a global net zero energy system. Launched at the 2017 IEA Ministerial to leverage the Agency’s expertise, insights and influence, the programme has provided world-class analysis, technical assistance and capacity building to support the most ambitious reorientation of the world’s energy systems this century. The CETP’s work is structured across three pillars of activity, with a particular focus on emerging markets and developing economies. The first of these focuses on supporting emerging and developing countries to establish…

Clean Energy Transitions Programme 2022
…not have been possible, with great benefit to the programme’s focus countries and IEA member countries alike.This CETP Annual Report 2022 provides an overview of the programme’s major achievements in the last year. During this time, the CETP has driven forward an ambitious and impactful agenda, even as the world has contended with multiple overlapping crises. As just some examples, the CETP delivered the Energy Sector Roadmap to Net Zero Emissions in Indonesia, which ministers strongly welcomed at the G20, and has played a key role in shaping Indonesia’s landmark Just Energy Transition Partnership (JETP). Similarly…

Implementing Clean Energy Transitions
Focus on road transport in emerging economies This report assesses the impact of the road transport sector on energy demand, CO2 emissions and air pollution in several selected major emerging economies over the coming decades under several IEA modelling scenarios. Most notably the Announced Pledges Scenario (APS) aims to show to what extent announced ambitions and targets, including the most recent ones, are on the path to deliver emissions reductions required to achieve net zero emissions by 2050.Bringing about a road transport decarbonisation pathway in line with the APS in the selected major emerging economies - Brazil, People’s Republic…

…Review was prepared in partnership between the Government of Portugal and the IEA. It draws on the IEA’s extensive knowledge and the inputs of expert peers from IEA Member countries to assess Portugal’s most pressing energy sector challenges and provide recommendations on how to address them, backed by international best practices. The report also highlights areas where Portugal's leadership can serve as an example in promoting secure and clean energy transitions. It also promotes the exchange of best practices among countries to foster learning, build consensus and strengthen political will for a sustainable and affordable energy future.

Scaling Up Demand Flexibility
…management to efficient system operation This report has been developed as part of the International Energy Agency (IEA) Digital Demand-Driven Electricity Networks (3DEN) initiative to examine the growing importance of demand flexibility in electricity systems amid rising demand, increased renewable energy integration and the electrification of power systems. Case studies in chronological order to examine the changing role of demand flexibility over time from South Africa (2025), Thailand (2030) and Ireland (2035) demonstrate how demand flexibility improves reliability, reduces costs, supports renewables integration and manages network constraints. To realise these benefits, the report emphasises the role for smart technologies…

…taken towards the liberalisation of energy markets, including the innovative creation of a single operator for the transport of natural gas and electricity, natural gas storage and operation of the Sines LNG terminal.
Still, a number of challenges remain. Energy markets are not as competitive as policy makers may have wished, and energy research and development policy coordination needs to be strengthened.
This review provides sectoral critiques of existing policy and recommendations for further improvements. It is intended to serve as an indispensable guide for Portuguese policy makers as they travel along the path to a more sustainable energy future… -

Energy Policies of IEA Countries: Portugal 2016 Review
…to examine implementation of energy policy to ensure that it remains relevant and cost-effective. Following the economic crisis, Portugal was left with a substantial tariff deficit as retail electricity tariffs were set below costs, including subsidies to renewables. Portugal’s plan to address the tariff deficit was the outcome of a negotiation process with industry stakeholders. Eliminating the tariff debt by 2020 is a significant challenge. The government must ensure swift implementation of all reform proposals and continue its efforts to identify further potential cost-saving measures in the energy sector. This review analyses the energy policy challenges facing…
