Dear colleagues, organizers and participants of the 6th Conference,

it is my great pleasure to be a member of the Scientific and organizing committee of the conference for several reasons. The main reason is that in today’s world, energy and ecology are in the focus of interest, and I am glad that the organizers of the conference are institutions of countries with whose scientific and educational institutions I have many years of successful cooperation. I regret that due to the Coronavirus Pandemic we will not have the opportunity for personal contact, but we remain in the hope that we will realize this next year.

I greet you from my city of Petrinja, where I live, and from Sisak, where I work, cities that were badly damaged in two strong earthquakes in December last year. However, that did not destroy our hope for recovery.

I wish you all the best in business and personal life,

Ladislav
