India's Clean Energy Startups See 100% Demand Surge

For seven years, Vishakha Chandere sold solar cookers and biochar stoves to a small circle of environmental enthusiasts in Pune. Last month, for the first time ever, her startup Orja Box completely sold out.

"Everyone seems to want a solar cooker or biochar stove now," says Chandere, who's witnessing a 100 percent surge in demand. Stores that once kept 50 clean energy stoves in inventory are now buying everything manufacturers can produce.

The sudden interest follows an LPG shortage affecting India, but clean cooking experts see something bigger happening. "This has woken people up," says Dr Ajay Chandak, who designs and commercializes solar cookers and biomass stoves. "We finally have an opening to talk about the future."

Priyadarshan Sahasrabuddhe, founder of Vaayu Biogas, has been LPG-free since 2019 using systems that convert food waste into clean cooking fuel. He's installed 450 units over seven years, mostly for individual homes, through quiet word-of-mouth growth.

Then his social media went viral. Now a major Pune ice cream manufacturer is calling, along with international companies wanting to power factory canteens for 1,400 workers.

"I never imagined this would happen," says Sahasrabuddhe. While his small operation can't fill massive orders overnight, the conversations themselves represent progress he's been working toward for years.

Hriday Energy Network's Hrushikesh Barve is fielding similar discussions about biogas, ethanol stoves, and bio-CNG alternatives. "A good discussion has started about how these technologies can be better manufactured and scaled," he says.

The momentum comes with growing pains. Many clean energy products require components that are temporarily hard to source, and innovators stress these are long-term solutions, not overnight fixes.

Why This Inspires

What took seven years of patient education to build is now accelerating in weeks. Solar cooker pioneer Vishakha Chandere is getting calls from across India, not just environmental activists but everyday families, small businesses, and industrial operations.

The shift matters beyond any single crisis. India has been quietly building an ecosystem of sustainable cooking alternatives through small startups, technology developers, and community organizations. These innovators worked for years when almost nobody was paying attention.

Now their phone lines are lighting up, and more importantly, people are listening to conversations about energy independence and sustainability that seemed impossible to start just months ago. "If we say we should have robust alternatives in place before the next crisis, people will listen now," says Sahasrabuddhe.

The breakthrough moment these clean energy pioneers waited years for has finally arrived.
