UKERC Summer School
If you are a PhD student in the energy domain then this summer school
can be a good opportunity to learn about the challenges in this domain
in a broader perspective. They normally prefer 2nd year PhD students but
1st year students are allowed to apply too.

I attended this summer school two years ago and found it very useful.
