…and second-generation biofuels. But thus far, no federal government policy is in place to establish as a target an absolute reduction of CO2 emissions. The resulting uncertainty risks holding back investments into new technologies and may delay projects that are urgently required. The transport sector will be a key to a sustainable success. In the short to medium term, reduced fuel demand through higher vehicle efficiency will increase security and reduce CO2 emissions. Yet the policy for the revision of CAFE (the corporate average fuel economy) standards will leave consumers with vehicles that fall short of the technological possibilities.

Scaling Up Demand Flexibility
From peak 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…

…in partnership between the Government of the United States and the IEA. It draws on the IEA’s extensive knowledge and the inputs of expert peers from IEA member countries to assess the United States’ most pressing energy sector challenges and provide recommendations on how to address them, backed by international best practices. The report also highlights areas where United States’ leadership can serve as an example in promoting secure 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 clean energy future.

Renewables 2020
…hurting – but not halting – global renewable energy growth. Half a year later, the pandemic continues to affect the global economy and daily life. However, renewable markets, especially electricity-generating technologies, have already shown their resilience to the crisis. Renewables 2020 provides detailed analysis and forecasts through 2025 of the impact of Covid-19 on renewables in the electricity heat and transport sectors. Executive summary Renewables’ resilience is driven by the electricity sector In sharp contrast to all other fuels, renewables used for generating electricity will grow by almost 7% in 2020. Global energy demand is set to decline 5% – but…

Energy Policies of IEA Countries: United States 2019 Review
…has achieved notable reductions in CO2 emissions over the past decade, led by its power sector. Low-cost shale gas combined with falling costs and policy support for renewables have shifted dependence away from coal-fired generation. Still, closures of coal and nuclear plants are expected to continue, requiring policy and regulatory responses to ensure a steady transition. Energy security remains a priority for the United States, which continues to demonstrate a strong focus on reliability and resilience. In this report, the IEA provides energy policy recommendations to help the United States smoothly manage the transformation of its energy sector.

Powering Ireland’s Energy Future
…this transition, supported by a detailed security study on the electricity supply mix.The analysis sets out five pillars for policy action: Establishing a cross-sectoral energy security strategy for the 2030s; delivering the enabling infrastructure to accommodate the growth of electricity demand and supply; accelerating the delivery of generation capacity, storage and demand-side flexibility; enabling secure system operation under high renewable penetration; advancing workforce skills, strengthening partnerships and facilitating electrification. Ireland can build on its progress in power system transformation to set an example of secure integration of large shares of variable renewable generation while safeguarding energy security.

…growth in demand. Growth in demand for gas has given rise to concerns about the diversity of the fuel supply and security of supply. Peat will become the only domestic energy resource in a matter of years, unless new gas development occurs to replace the Ballycotton and Kinsale gas fields. There is no electricity interconnector other than to Northern Ireland, and the single gas interconnector is close to full capacity. Policies on peat have had social objectives. These objectives may not be compatible with economic efficiency and environmental objectives and could have implications for the future of the energy sector…

Energy Policies of IEA Countries: Ireland 2019 Review
…to transform its energy sector, Ireland is not on course to meet its 2020 greenhouse gas emissions reduction target. The decarbonisation of heating in buildings, one focus of this report, is a particular challenge.
In a more positive development, wind power accounted for around one-quarter of total generation in 2017 – the third-highest share of all IEA member countries. Additionally, this report suggests that Ireland has considerable scope to further advance alternative means of transport and public transport infrastructure, especially in urban areas.
In this report, the IEA provides recommendations for further improvements of Ireland’s energy policy to…

…finds that US energy policy has an influence on energy policy throughout the world. The 2001 National Energy Policy is an important development. The US is taking unilateral action as an alternative to the Kyoto Protocol. This report urges consideration of legislation on carbon dioxide and adoption of policies allowing international trading in emissions. Strengthening fuel economy standards is an encouraging approach to energy use in transport. Different standards for cars and light trucks should be addressed as a priority. Policies to promote new sources of energy supply should be balanced by continuing effort to enhance efficient use of energy…
