Dear readers,
This issue dedicated to new trends arrives with perfect timing. After the past two drought years, so to speak, we are finally seeing a rising trend in new innovations. For some of those I have wondered how come they have not turned up even sooner.
In this interview, Stephane Schaal of Hitachi Energy discusses in detail some major trends, primarily with regards to energy efficiency standards, decarbonization and digitalization, which now shape our industry and will continue to do so for a long time. One of his conclusions is that only the most agile and innovative players will be able to transform the challenges into opportunities.
