Is there any EU funding available for organisers of an Energy Day? Can you recommend potential sponsors?

There is no EU funding for organising an Energy Day, nor referrals to potential sponsors. By registering your event as an Energy Day, it will gain more visibility as a key component of the EU Sustainable Energy Week (EUSEW) via the EUSEW website. You will also be provided with a promotional toolkit to help further promote your event online and offline.
