Thinking Energy

Discussing how to make intelligent decisions about energy


My name is Barny Evans and in work I specialise in renewable energy, sustainable development and energy policy. I have worked in this sector for over 12 years but it is also my interest and I spend a lot of my time reading, thinking and talking about these subjects.

I do write a fairly regular blog for Building magazine and have written or co-written several papers, including one on all-electric cities, overheating in new homes and on energy storage. Despite that I was keen to share my thoughts and learning because I think “sustainable” energy is one of those areas where I think we all need to be more literate and make better decisions for a more efficient, cleaner and greener energy system and built environment.

So, this is my truth, tell me yours.
