My mission

To prove wind, solar and batteries can reliably power the world — one bankable hybrid project at a time.

I'm Charles Haworth, co-founder of Modaso Energy and Tessera Hybrid. I build renewable energy at scale, run my businesses on AI, and write about both.

Speaking & podcasts

I speak from the operator's seat, not the analyst's: financing and building energy projects, and running a real company on AI. Happy to speak on anything across:

Renewable energy & the transition

Hybrid wind-solar-battery, firm baseload power, Africa, hydrogen and the economics behind it.

AI-native companies

Running a real business on an AI operating layer — what it automates and what it changes.

Leadership & investing

Building high-performing teams, closing big deals, and long-horizon investing.

Everything a producer needs — bio, headshot, talk abstracts — on the Speaking page.

Invite me to speak

Conferences, podcasts, and panels on the energy transition and applied AI. For everything else, the essays are free.
