Looking for a writer who gets sustainability?

You don’t need a technical expert (you probably have plenty of those) but you do need someone who understands the subject matter well enough to translate dry technical details into clear and compelling stories for your customers. Most generalist content writers just can’t do that effectively for the sustainability and clean energy sector.

But I know my way around the acronym soup that is corporate sustainability and the jargon jungle of energy systems.

I have been working and writing in the sustainability space for almost 9 years, including comms & marketing roles at the environmental disclosure non-profit CDP, the climate tech startup TransitionZero, a boutique eco-architecture firm, and running my own blog on climate politics.
I have developed a strong base of knowledge in climate & sustainability, particularly corporate sustainability, the clean energy transition and the built environment.

This means I can ask good questions, save you time by getting started quickly, and deliver well-informed, thoughtful content.

Why clean energy?

The climate crisis is the biggest challenge of our time, and the clean energy transition is the biggest opportunity of our time.  

Renewable energy from the sun, wind and water has the potential to power our whole world, without carbon emissions. Innovations in zero-carbon buildings, heating, distributed energy and energy storage are also key to this transformation. Not only is this shift essential for the climate, it’s also a massive business opportunity. Clean energy is booming. Renewables accounted for the biggest growth in energy capacity in 2023. We are living through a new green industrial revolution.  

Clean energy is dynamic and complex. Customers need to be educated on the problems and solutions in an engaging way that resonates with their needs.  

With excellent content and copywriting, the clean energy sector can grow even faster.  

And the more your clean energy business succeeds, the closer we all get to a beautiful zero-carbon energy future. That’s why I want to help you grow!
