All Office of Energy Efficiency and Renewable Energy (EERE) office and partnership websites must use domains and URLs that have been approved by the Department of Energy (DOE)’s Chief Information Office, the Office of Management and Budget (OMB), and EERE's domain policies. URLs

The EERE website is hosted on the domain. All EERE websites will use an URL unless the Web Governance Team approves it to be hosted outside of the content management system (CMS).

New websites are usually created in their own nested group. A nested group is a sub-section of the EERE website with unique URL and navigation.

Example nested group website URLs:

  • Bioenergy:
  • Communication Standards:

Example content page URL:


Requesting a New Nested Group

Nested groups require Web Governance Team review and approval. Gather key project information and discuss the nested group request at a weekly Web Governance Team meeting.

Requesting Redirects

EERE can create redirects at the or EERE levels. These short URLs will automatically redirect to the full-length URL of another web page. These are typically used in marketing materials where the team needs a short, easy-to-use URL.

Example URLs:

For a redirect at the level, contact the EERE Web Enterprise Manager for approval.

For a redirect at the level, contact the EERE Web Enterprise Manager and the Web Governance Team Facilitator. DOE Public Affairs must approve any redirects at the level.

Non-Standard EERE URLs

Some EERE websites are hosted outside of the CMS because they have unique technical requirements.

URLs Hosted Outside of CMS

Websites hosted outside of the CMS often have URLs at or at (name)

If you believe your site requires a URL outside of the CMS, attend a Web Governance Team meeting. Once it is determined that the website needs to be hosted outside of, the Web Governance Team will send the request to DOE Public Affairs for formal approval. DOE Public Affairs will approve the hosting location and the URL.

Example URLs:

  • The EERE Publications Library:
  • Better Buildings Initiative:
  • WINDExchange:

Legacy Marketing URLs

EERE previously created "marketing URL" redirects at EERE will no longer create new redirects in this format, but the old redirects have been grandfathered in and may still be used by the technology offices to promote their websites. There are no plans to retire the old URLs.

The redirects below redirect to the technology office home pages on

Example URLs:


All 11 of EERE's research offices have a URL in this format that redirects to their office home page. These will remain in place.

Top-Level .gov Domains

UPDATE: New .gov domain requests are paused until January 2024 as the federal government transitions to new infrastructure.

Top-level .gov domains are reserved for federal agencies. Agencies can establish .gov domain names for any legitimate purpose, and are encouraged to register domains as needed to most effectively meet their mission. However, .gov domain names are a shared resource across all U.S.-based government organizations and agencies have a responsibility to carefully consider how potential domain names might impact the public and how they interact with government information and services.

At DOE, unique .gov domains are only approved for high-level, cross-cutting initiatives, and they are very rarely approved.

Learn more about the U.S. Department of Energy's .gov approval process on the DNS Policies and Procedures page.

  • Example URLs:
    • (Solar Decathlon)
    • (EERE Building Energy Codes Program)

To request a new top-level .gov, go to the Web Governance Team

Domain Request Reviews

Federal executive branch agency requests for new .gov domains will be reviewed by the Office of Management and Budget (OMB) as required by M-23-10, "The Registration and Use of .gov Domains in the Federal Government."

When submitting a request, you must describe:

  • What the domain will be used for
  • Who the intended audience is for the domain, including primary users
  • Why the specific domain name is needed and how it follows the naming requirements.

All domain requests must have the approval of the DOE Chief Information Officer, or the head of the agency.

In areas of domain name conflict, OMB will seek resolution with the agencies involved. OMB may deny a domain name request or a domain name renewal, or may request that an agency transfer ownership of an existing domain to another agency to remediate potential conflict or confusion. Agencies that do not follow the requirements and prohibitions below may have the relevant domain name transferred, terminated, or not renewed.

Best Practices

Best practices for agencies requesting domains include:

  • Agencies should be careful when establishing domain names, as not all agency work warrants a separate brand or product identity.
  • Generic names may not be approved when an agency lacks significant or singular authority over a thematic topic; or if the requested domain name could be ambiguous or likely to mislead or confuse the general public.
  • Agencies should avoid requesting unnecessary domain name variants unless there is a compelling need.
  • Agencies should strive to keep their domain name under 15 characters, and include only letters, numbers, or a hyphen

More information on requirements for domain requests can be found on

.ORG Domains

.Org domains are available only for websites that are not part of a federal agency, are not funded by the DOE, or are developed through significant partnership arrangements with non-federal agencies. Special approval is required for these sites.

To request a new .org domain, go to the Web Governance Team. Note that EERE does not approve websites on .com, .net, or other domains.
