Given the evidence about climate change impacts and remaining uncertainties associated with the future configuration of energy systems and infrastructure, there is high confidence that U.S. energy systems will evolve in ways that affect risk with respect to climate change and options for adaptation or mitigation.' contributors: [] description: 'As new investments in energy technologies occur, future energy systems will differ from today’s in uncertain ways. Depending on the character of changes in the energy mix, climate change will introduce new risks as well as opportunities.' display_name: NCA3 Finding 4.5 evidence: 'A number of studies describe U.S. energy system configurations in terms of supply and use assuming different scenarios of climate change, including SRES B1 and A2.4b3a36af-895d-4151-9fbc-206d991558cb,6ac1aea5-6b76-46e1-822e-664cb3d11e9a,2e002d5f-fcf1-4d2e-a8b9-7f672a26e5a1 A technical input report to the NCA by DOEf0803451-5a89-474a-974f-99c13fdc725d,3c34748e-be5d-4831-896e-70cbae0f0d22 provides details and updates earlier studies.

Early in the development of key messages and a chapter outline, the authors reviewed all of the four dozen relevant technical input reports that were received in response to the Federal Register solicitation for public input. Selected authors participated in a U.S. Department of Energy (DOE) sponsored workshop on Energy Supply and Use, December 29-30, 2011 in Washington, D.C. The workshop was organized specifically to inform a DOE technical input report and this National Climate Assessment and to engage stakeholders in this process. The authors selected key messages based on the risk and likelihood of impacts, associated consequences, and available evidence. Relevance to decision support within the energy sector was also an important criterion.\r\nThe U.S. maintains extensive data on energy supply and use. The Energy Information Administration (EIA) of the U.S. Department of Energy is a primary organization in this activity, and data with quality control, quality assurance, and expert review are available through EIA Web pages (for example, EIA 2012, EIA 20132af3709d-81eb-48b7-9183-afc6c27015ea,9f0adb9b-5a9c-4fc2-8df7-ebed4322e185)." references: - href: http://52.38.26.42:8080/reference/2af3709d-81eb-48b7-9183-afc6c27015ea.yaml uri: /reference/2af3709d-81eb-48b7-9183-afc6c27015ea - href: http://52.38.26.42:8080/reference/2e002d5f-fcf1-4d2e-a8b9-7f672a26e5a1.yaml uri: /reference/2e002d5f-fcf1-4d2e-a8b9-7f672a26e5a1 - href: http://52.38.26.42:8080/reference/3c34748e-be5d-4831-896e-70cbae0f0d22.yaml uri: /reference/3c34748e-be5d-4831-896e-70cbae0f0d22 - href: http://52.38.26.42:8080/reference/4b3a36af-895d-4151-9fbc-206d991558cb.yaml uri: /reference/4b3a36af-895d-4151-9fbc-206d991558cb - href: http://52.38.26.42:8080/reference/6ac1aea5-6b76-46e1-822e-664cb3d11e9a.yaml uri: /reference/6ac1aea5-6b76-46e1-822e-664cb3d11e9a - href: http://52.38.26.42:8080/reference/9f0adb9b-5a9c-4fc2-8df7-ebed4322e185.yaml uri: /reference/9f0adb9b-5a9c-4fc2-8df7-ebed4322e185 - href: http://52.38.26.42:8080/reference/f0803451-5a89-474a-974f-99c13fdc725d.yaml uri: /reference/f0803451-5a89-474a-974f-99c13fdc725d report_identifier: nca3 statement: 'As new investments in energy technologies occur, future energy systems will differ from today’s in uncertain ways. Depending on the character of changes in the energy mix, climate change will introduce new risks as well as opportunities.' type: finding uncertainties: 'Understanding of options for future energy supply and use within the U.S. improves, as the EIA and other organizations update data and information about U.S. energy systems as well as projections of the mix of primary energy under various assumptions about demographic, economic, and other factors. With additional data and better models, alternative energy mixes can be explored with respect to climate change adaptation and mitigation. But numerous factors that are very difficult to predict – financial, economic, regulatory, technological – affect the deployment of actual facilities and infrastructure.
