8 Companies Turn Waste into Clean Energy and Internet Access

Geothermal energy just got its biggest breakthrough in decades, and it happened by borrowing tricks from an unlikely source: the oil industry.

Fervo Energy's Cape Station in southwestern Utah will start feeding clean electricity to Southern California homes later this year. Unlike solar panels that stop when the sun sets or wind turbines that idle on calm days, this geothermal plant will run 24/7 without pause.

Founder Tim Latimer adapted horizontal drilling techniques from oil and gas extraction to pump water through naturally hot underground rock. The result is constant, reliable renewable energy that could scale to 100 megawatts by 2027, enough to power roughly 70,000 homes.

The company's recent public debut valued it at $3 billion, signaling investor confidence that geothermal can finally compete with traditional power sources. For communities tired of choosing between reliability and sustainability, Cape Station offers both.

But Fervo isn't alone in rethinking resources. Curio is tackling one of nuclear energy's biggest problems: what to do with spent fuel rods. Their recycling process transforms nuclear waste into reusable uranium, dramatically cutting both disposal costs and environmental concerns.

In remote villages where digging trenches for fiber optic cables costs millions, Taara brings fiber-speed internet through wireless optical communication. No excavation, no cable, just connectivity beaming through the air to places previously left in the digital dark.

Even invasive species are getting a second life. One honoree discovered that crown-of-thorns starfish, which devastate coral reefs, can be processed into effective road deicer.

The Ripple Effect

These eight companies share a common thread: they see opportunity where others see obstacles. Plastic waste becomes circular carbon at Cecilia. Municipal utilities get easier-to-use digital manuals from LSPS Solutions. Each project chips away at the false choice between economic growth and environmental responsibility.

The Fast Company World Changing Ideas recognition highlights solutions that work right now, not decades from today. Cape Station's grid connection this year proves clean baseload power is ready for prime time.

When drilling expertise meant for extracting fossil fuels instead taps Earth's natural heat, the energy transition stops feeling like sacrifice and starts feeling like innovation.
