Really Good Ideas


MSc Organisational Psychology

Chartered Civil Engineer

Practitioner Member of the Association of Business Psychology

I have extensive engineering and corporate development experience in the infrastructure sector and a record of delivering novel behavioural insights projects.

I began my career in engineering consultancy, later moving to major projects contracting before leading strategy and business development projects in the managed services sector.

I advise clients on the behavioural aspects of major infrastructure projects, procurement exercises and provide a critical review of behavioural programmes in both the programme implementation and mobilisation phases.

I am also an Associate Tutor for Birkbeck’s Organisational Psychology MSc and an Independent Financial Adviser.

When not engrossed in all the above I escape to enjoy running and cycling in the hills and woods near where I live.

Charlotte Powell



Chartered Civil Engineer

MSc Renewable Energy and Environment

I have programme management, engineering and operational leadership experience of large complex infrastructure and technology projects involving green technology, renewable energy, carbon capture, bio-degradable waste management and sustainable construction. I have been privileged to work on ground-breaking initiatives, not just in the UK, but also Europe, Australia and North America.

I have championed sustainable energy solutions and as a Chartered Civil Engineer, having moved from the defence sector to the renewable energy sector over 15 years ago, I continue to  challenge the status quo. As  John F Kennedy said:

“Change is the law of life and those who look only to the past or present are certain to miss the future”.

In 2018 I established Eighty20 Consultants to help all businesses, including SMEs and start-ups, in the green and renewables sector. Whether developing their commercial offer or seeking significant expansion through market or product diversification I can help develop business strategy, build partnerships and embed cultural change. I know first-hand, that In a rapidly developing sector where technology and processes are changing at pace, it really is possible to make a positive difference to address a global challenge.  

I am also a Trustee and Non-Executive Director of the MCS Charitable Foundation, which is helping create a world where everyone can access to affordable and reliable renewable energy.
