Wishful plans to replace large proportions of fossil fuel with renewable energy should be replaced with a holistic approach enabling us to attain the best possible energy mix for the environment.

Given the precarious need for climate change mitigation and a scarce supply of renewable energy sources in the foreseeable future, renewable energy sources should be deployed where the climate effect is highest, which sometimes implies a tradeoff between sectors.

Since 2010, Solvang has pursued an innovation path to bring heavy fuel oil (HFO) operation into compliance with the strictest NOx emission control. The climate gain is significant.
