Accelerating Decarbonization Of The U S Energy System

The world is transforming its energy system from one dominated by fossil fuel combustion to one with net-zero emissions of carbon dioxide (CO2), the primary anthropogenic greenhouse gas. This energy transition is critical to mitigating climate change, protecting human health, and revitalizing the U.S. economy. To help policymakers, businesses, communities, and the public better understand what a net-zero transition would mean for the United States, the National Academies of Sciences, Engineering and Medicine convened a committee of experts to investigate how the U.S. could best decarbonize its transportation, electricity, buildings, and industrial sectors. This report, Accelerating Decarbonization of the United States Energy System, identifies key technological and socio-economic goals that must be achieved to put the United States on the path to reach net-zero carbon emissions by 2050. The report presents a policy blueprint outlining critical near-term actions for the first decade (2021-2030) of this 30-year effort, including ways to support communities that will be most impacted by the transition.

Addressing climate change is essential and possible, and it offers a host of benefits - from better public health to new economic opportunities. The United States has a historic opportunity to lead the way in decarbonization by transforming its current energy system to one with net-zero emissions of carbon dioxide. Recent legislation has set the nation on the path to reach its goal of net zero by 2050 in order to avoid the worst consequences of climate change. However, even if implemented as designed, current policy will get the United States only part of the way to its net-zero goal. Accelerating Decarbonization in the United States provides a comprehensive set of actionable recommendations to help policymakers achieve a just and equitable energy transition over the next decade and beyond, including policy, technology, and societal dimensions. This report addresses federal and subnational policy needs to overcome implementation barriers and gaps with a focus on energy justice, workforce development, public health, and public engagement. The report also presents a suite of recommendations for the electricity, transportation, built environment, industrial, fossil fuels, land use, and finance sectors.

The United States, partner countries and philanthropies are joining forces to accelerate the transition to clean, secure energy systems and build a Net Zero World. The Net Zero World Initiative leverages expertise across U.S. government agencies and Department of Energy (DOE) national laboratories, in partnership with other governments and philanthropies, to accelerate the decarbonization of global energy systems. This whole-of-government approach supports countries committed to raising their climate ambitions by creating and implementing highly tailored, actionable technical and investment strategies that put net zero within reach. The Net Zero World Initiative enables country partners to harness the power and technical expertise of U.S. and international industry, think tanks, and universities.

While technologies are clearly instrumental in transitioning away from fossil fuel-based energy and toward a decarbonized economy, decisions about which technologies are prioritized, how they are implemented, and the policies that drive these changes will have profound effects on people and communities, with important implications for equity, jobs, environmental and energy justice, health, and more. The National Academies of Sciences, Engineering, and Medicine Committee on Accelerating Decarbonization in the United States: Technology, Policy, and Societal Dimensions was tasked with assessing the broad range of technological, policy, and societal dimensions of decarbonizing the U.S. economy. The committee produced a 2021 report that provides the U.S. government with a roadmap of equitable and robust decarbonization policies. The next report of the committee will address the broader range of policy actors who play a role in equitable energy transition. To inform its deliberations, the committee hosted a 1-day workshop on July 26, 2022 to discuss critical issues of equity and justice during the energy transition. The goal of the workshop, titled Pathways to an Equitable and Just Transition: Principles, Best Practices, and Inclusive Stakeholder Engagement, was to move beyond energy technologies and elicit ideas and insights to inform the development of principles, best practices, and actionable recommendations for a broad range of policy actors and stakeholders in order to fully operationalize equity, justice, and inclusion. This publication summarizes the presentations and discussion of the workshop.

While progress has been made in the development of decarbonization technologies, much work remains in scale-up and deployment. For decarbonization technologies to reach meaningful scale, real-world constraints, societal, economic, and political, must be considered. To identify the primary challenges and opportunities to deploying decarbonization technologies at scale across major sectors of the U.S. economy, the Board on Energy and Environmental Systems of the National Academies of Sciences, Engineering, and Medicine convened a workshop on July 22-23, 2019. In addition to technology-specific and sector-specific studies, the workshop considered the types of societal transformations required, as well as potential policy drivers for carbon dioxide emissions reductions. This publication summarizes the presentations and discussion of the workshop.

Clean energy innovation is central to the fight against climate change. To rise to this challenge, the United States should launch a National Energy Innovation Mission. Led by the president and authorized by Congress, this mission should harness the nation's unmatched innovative capabilities-at research universities, federal laboratories, and private firms (both large and small), in all regions of the country-to speed the progress of clean energy technologies. To jumpstart this mission and unlock a virtuous cycle of public and private investment, the US federal government should triple its funding for energy research, development, and demonstration (RD&D) over the next five years to $25 billion by 2025. "Energizing America" offers policymakers a strategic framework to build a growing RD&D portfolio over the next five years, detailed fundingproposals across the full spectrum of critical energy technologies, and recommendations for immediate action.

Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.

Climate change is a key problem of the 21st century. China, as the largest emitter of greenhouse gases, has committed to stabilize its current emissions and dramatically increase the share of electricity production from non-fossil fuels by 2030. However, this is only a first step: in the longer term, China needs to aggressively strive to reach a goal of zero-emissions. Through detailed discussions of electricity pricing, electric vehicle policies, nuclear energy policies, and renewable energy policies, this book reviews how near-term climate and energy policies can affect long-term decarbonization pathways beyond 2030, building the foundations for decarbonization in advance of its realization. Focusing primarily on the electricity sector in China - the main battleground for decarbonization over the next century – it provides a valuable resource for researchers and policymakers, as well as energy and climate experts.

The United Kingdom is committed to reducing its greenhouse gas emissions by at least eighty per cent by 2050, a target that will only be achieved by transforming the way that energy is supplied and used. At the same time there are anxieties about the security of energy provision in terms of European dependency on natural gas and the reliability of electricity supply. This book explores in detail those factors which could help or hinder the attainment of the UK's climate change targets, and how these factors interact with the parallel objective of maintaining a robust and secure energy system. The book is the result of a major national energy research effort by the UK Energy Research Centre, which includes some of the UK's leading energy experts. The results and recommendations are essential reading for policymakers, professionals, researchers, and anyone concerned with achieving large-scale reductions in carbon emissions, both from the UK and internationally. Energy 2050 begins by exploring the evolution of the UK energy system over recent decades: the trends, technologies and environmental impacts related to energy use, and the structures and institutions of governance that have influenced this evolution. It then moves on to changes in energy policy to emphasise decarbonization and resilience, and introduce the approach to scenarios and modelling used in the rest of the book. Later chapters explore different aspects of the uncertainties that may enable or constrain the creation of a low-carbon, resilient UK energy system, related to accelerated technology development, the creation of an infrastructure to support de-centralized energy and microgeneration, to lifestyle and behaviour change, and to public attitudes to wider environmental impacts associated with energy system change.
