The .energy zone is a generic extension, so it is not linked to any country. Energy is the capacity to do work, and in everyday use the word means power, heat, fuel and the supply that keeps homes and factories running. Installers of solar panels, heating engineers, consultants, researchers and community projects may choose a .energy name, because the ending points to their field at once. Use the availability form just below this text to see whether your name in .energy is still free.

A short history
The .energy extension came with the group of newer generic endings. Its clear meaning has made it a common choice in the energy trade and among renewable projects, although it is still less familiar to the public than older endings such as .com. Because energy topics change quickly, many sites in this field revise their content often.
Who runs it
As a generic zone, .energy is run by a registry operator under an agreement with ICANN, the organisation that coordinates the global domain name system. The operator sets the registration policies and keeps the database, while accredited registrars sell names and forward the orders. Policies can be revised, so the terms in force on the day of your order are the ones to read.
Rules in practice
- Open registration: generic zones are usually open to businesses and individuals alike, although the operator can attach conditions on acceptable use.
- Holder details: the information provided must be accurate, and the registrar may ask for confirmation.
- Characters: names use letters, digits and hyphens, and a single label can be up to 63 characters long.
- Renewal: set a reminder for the expiry date and enable auto-renewal, so that the name stays with your business.
Who uses .energy
- Installers of solar panels, heat pumps and battery storage who explain their services and projects.
- Energy consultants, auditors and advisers who help households and businesses plan their use of power.
- Research groups, clean-energy initiatives and community projects that share data and news.
- Suppliers and engineering firms that publish technical guides and project pages.
Strengths
- The word is clearly linked to power and fuel, so a visitor knows the subject before clicking.
- It is short and easy to say, which helps when you explain your business in person or on the phone.
- Because the zone is generic, it can serve projects in several countries.
Things to keep in mind
- Energy topics are often regulated. Claims about savings, output or efficiency should be specific, accurate and supported by evidence.
- Some energy services need licences or certificates in certain places, so show the ones you hold and do not imply others.
- A broad word is common, so pairing it with a place or a service often makes the name clearer.
- Visitors may still look for .com first, so consider whether you want both addresses.
Tips before you register
- Check the name in .com and in the business registers and social channels you plan to use.
- Write the company details exactly as they appear in your official records.
- Publish clear pages for services, certifications and contact information before you start promoting the site.
- Set up mail authentication records before you send quotes or invoices from the domain.
- Use two-factor login on the registrar account and keep the expiry date in your calendar.
Frequently asked questions
Is .energy only for energy companies? No. Consultants, researchers and community groups use it too, as long as the content fits the theme.
Can a .energy site promise lower bills? Avoid promises you cannot document. State what your service does and, if you cite savings, explain how they were measured.
Does .energy help a site rank in search results? It may help visitors understand the subject, but search results depend mainly on the quality of the content, the speed of the pages and the links that point to them.
