Dear Angela,

for Greece you could check this page, it has detailed monthly reports on electricity generation by type of fuel.

The only bad thing.....it's in Greek..

With a little patience you could understand and extract the data.

Good luck,

Nikos

Thanks for your answer Nikolaos, it is really useful.

Hello Angela,

You can browse through https://www.iea.org/publications/

They have provided such data since around 2010 (the moment I started to follow a new publications) but hopefully you might find some earlier reports, too.

Best of luck, Adam.

try International Energy Agency reports as they provide complete data year wise.
