Tumbling offshore wind costs, the big-data revolution, innovation in wind and PV, the transformation of utilities, corporate PPAs, and the roles of batteries and hydrogen in the energy transition – these were just a few of the issues tackled at the 2017 Recharge Thought Leaders Summit.

Held last Thursday amid the spectacular setting of the Holmenkollen Park Hotel high above Oslo, the annual invitation-only event brought together leading figures from the wind and solar sectors, financiers, policy experts and others industrial influencers to discuss the key challenges facing renewables and the wider energy sector in an era of profound upheaval.
