The National Academy of Sciences was established in 1863 by an Act of Congress, signed by President Lincoln, as a private, nongovernmental institution to advise the nation on issues related to science and technology. Members are elected by their peers for outstanding contributions to research. Dr. Marcia McNutt is president.
The National Academy of Engineering was established in 1964 under the charter of the National Academy of Sciences to bring the practices of engineering to advising the nation. Members are elected by their peers for extraordinary contributions to engineering. Dr. John L. Anderson is president.
The National Academy of Medicine (formerly the Institute of Medicine) was established in 1970 under the charter of the National Academy of Sciences to advise the nation on medical and health issues. Members are elected by their peers for distinguished contributions to medicine and health. Dr. Victor J. Dzau is president.
The three Academies work together as the National Academies of Sciences, Engineering, and Medicine to provide independent, objective analysis and advice to the nation and conduct other activities to solve complex problems and inform public policy decisions. The National Academies also encourage education and research, recognize outstanding contributions to knowledge, and increase public understanding in matters of science, engineering, and medicine.

Consensus Study Reports published by the National Academies of Sciences, Engineering, and Medicine document the evidence-based consensus on the study’s statement of task by an authoring committee of experts. Reports typically include findings, conclusions, and recommendations based on information gathered by the committee and the committee’s deliberations. Each report has been subjected to a rigorous and independent peer-review process and it represents the position of the National Academies on the statement of task.
Proceedings published by the National Academies of Sciences, Engineering, and Medicine chronicle the presentations and discussions at a workshop, symposium, or other event convened by the National Academies. The statements and opinions contained in proceedings are those of the participants and are not endorsed by other participants, the planning committee, or the National Academies.
Rapid Expert Consultations published by the National Academies of Sciences, Engineering, and Medicine are authored by subject-matter experts on narrowly focused topics that can be supported by a body of evidence. The discussions contained in rapid expert consultations are considered those of the authors and do not contain policy recommendations. Rapid expert consultations are reviewed by the institution before release.

The world is about to undergo one of the greatest transformations in human history. To avoid irreparable damage to the natural world and to human health and well-being, societies must move away from a heavy reliance on fossil fuels to energy systems that result in no net release of carbon dioxide to the atmosphere.
Engineers will be at the vanguard of this energy transition. They will develop, commercialize, implement, and evaluate the technologies that will result in net-zero carbon. They will work with natural and social scientists, policymakers, and the general public to provide guidance on needed investments and technological options.
The energy transition is already underway, and many countries and regions have committed to reducing their greenhouse gas emissions and replacing them with renewable and other non-carbon-producing energy sources. But no one energy technology has emerged as the obvious solution to the immense challenges of this critical transition. All potential energy sources need to be on the table.
At the 2022 forum of the National Academy of Engineering’s annual meeting, five prominent engineers who are experts in the area of energy discussed the transition to net-zero carbon:
The forum was again adroitly moderated by television host and entrepreneur Deanne Bell. Drawing on her background in engineering and expertise in communicating with the public, she helped ensure that the forum was both substantive and engaging.
Engineers transform human life through the creation and refinement of new and existing technologies. Today they are being asked to undertake a task more momentous than any they have taken on previously. I’m confident that they will rise to the occasion.
