From the Extreme Energy Gathering website:

Extreme Energy is the process where energy extraction methods grow increasingly more intense over time, as easier to extract resources are depleted. A number of new extraction methods threaten to devastate our countryside, while increasing our contribution to the global ecological crisis.
Empowering and connecting communities to resist this destruction is crucial. The gathering aims to provide a space to allow diverse campaigns to meet, share information and support each other. In particular it is intended to help network people who are organising to resist including those from threatened communities.
