Q. What is ‘My Profile’?

As a registered user, when you are logged in you will have access to your profile page

In this area you can update your password and, if you are an EI Member, you can also update your interests and work areas.

The profile page also recognises EI Scientific and Technical Committee members (who gain access to a secure working area) and any other subscriptions you have.

Q. What is ‘My Library’?

‘My Library’ is your e-bookshelf – here, as a registered user, you can store the documents and searches you want to keep. Next time you login, they will be saved and easy for you to access.

Documents on this website can be found by using either the quick search facility or by the advanced search tool. The quick search tool and the link to the advanced search tool are located above (in the green bar). You can also browse the Energy Matrix, a powerful search tool for retrieving energy information classified by relevant topics.

Q. How does the search engine work?

When you search, using a word or phrase, the search engine returns your results by ‘content type’ which are:

  • Published Resources
  • News and Abstracts
  • Contacts and Networks
  • Training and Events
  • Periodicals

You can switch from one content type to another by clicking on the blue tabs.

Each content type is then divided into different “Types” such as books, articles, organisation addresses, conferences or job profiles.

Q. How does the Energy Matrix work?

The Energy Matrix is a compilation of links, themes and categories that correspond to the energy value chain – moving from primary energy production through conversion, transportation and end use to reuse of energy. The categories and themes we use have been classified according to international standards (e.g. International Recommendations for Energy Statistics) and recommendations from EI members.

To browse the Energy Matrix, simply click on the category you are interested in to return the relevant material across a broad range of curated content and record types (e.g. books, periodicals, courses, addresses, etc.). In some cases, we have identified sub-categories, which help you to dig even further into your chosen subject. Sub-categories will appear as you hover your mouse over the Energy Matrix.

Q. Where does the content come from?

The EI Knowledge Service team is continually adding new, relevant content to the Energy Matrix. This content is taken from a range of internal and external sources, depending on its type. This includes more than:

  • 30,000 news items
  • 19,000 bibliographic records for books and reports – all of which are available at the EI
  • 16,000 journal abstracts
  • 7,000 organisation addresses
  • Job profiles, factsheets, periodicals and statistics.
