Who they are
Rosemary Barnes is an engineer and the creator of Engineering with Rosie, a channel about energy technology and infrastructure. Her videos explain engineering questions involving energy systems, including renewable power and the equipment and processes used to produce and manage electricity. She presents technical topics with calculations and engineering reasoning, helping viewers understand assumptions as well as conclusions. The channel focuses on energy rather than the full range of civil practice, but its treatment of technical evidence can be useful to engineers working with energy projects.
Why firm owners follow them
For firms involved in energy, utilities, or related infrastructure, Barnes's explanations can help staff build subject knowledge and prepare better questions for project teams and clients. Her calculation-based approach can also serve as a prompt for staff training on how to communicate assumptions and technical tradeoffs. Owners should check applicable codes, project criteria, and local requirements separately, since a public educational channel is not a substitute for design guidance, licensure advice, or market pricing information.
How to use them: Use a video relevant to your practice as a prompt for a technical lunch discussion.
