David Jozefy, Chodov, Czech Republic. A true guru of the Czech wind energy industry, David Jozefy has been involved in the industry for the last 20 years. He probably knows the story behind every windmill in the country. He is a consultant, owner and developer of wind energy and is currently working on several projects all that were approved before the clean energy freeze currently underway in the Czech Republic. He believes that to change the energy system it needs to come from a government level and that the Czech national plans have to coincide with the promises being made at an EU level.
