Introduction
In 2026 some of the most important energy and renewable energy trade shows in the world will happen in the United States, in Europe and in Australia. The events will centre on solar power, storage, wind power, batteries, smart energy, decentralised power, clean technology and the broader energy transition.
For energy companies, attending a major exhibition is only the beginning; the true value is derived from identifying the correct companies and professionals to get in touch with before the event, contacting them, and then staying in contact with them afterwards.
The eight events mentioned below have been selected on the basis of their size, significance to the industry, and business value; our decision was to concentrate on major events rather than on smaller regional ones.
