Power up for a changing climate.

Inspiration

Every time I hear about another El Niño season, an atmospheric river, or the possibility of widespread power outages in California, I find myself asking the same questions: How will this affect my home? Is my family prepared? What should I be doing differently?

As a parent, I feel a growing anxiety about the changing climate. There is no shortage of news reports about extreme weather, wildfire smoke, grid reliability, and climate risks. But so much of that information stops at telling us what could go wrong.

What I really want to know is: What can I do about it?

Having worked in clean energy and climate technology, I've seen firsthand how much innovation is happening in solar, battery storage, electrification, and grid resilience. Yet there is still a gap between these sophisticated technologies and the everyday decisions households need to make.

The climate is changing, and the next generation of consumers needs a different entry point.

Not everyone is ready to invest in solar and storage. Some rent, some own, and many face affordability constraints. But everyone needs to navigate a changing climate.

That's what inspired matcha—a personal climate resilience companion built with the simplicity of a wellness app and the intelligence of a climate resilience platform.

What it does

matcha helps people move from climate awareness to meaningful action, one Power Move at a time.

The experience revolves around three features:

🍵 Power Brew — Your daily climate check-in

Power Brew brings together local weather, air quality, weather alerts, and reported power outages into an approachable, personalized briefing.

Instead of navigating multiple news reports and technical dashboards, users can understand what's happening around them and discover a relevant next step.

Power Brew also includes audio narration, making climate preparedness something you can listen to as part of your daily routine.

⚡ Power Match — Resilience that fits your life

Power Match helps users explore household resilience solutions based on their needs and priorities.

For example, someone concerned about power outages can identify essential devices, select a desired backup duration, and calculate the approximate battery capacity required.

The goal is to make energy resilience understandable and accessible, whether someone is renting an apartment or considering larger investments in their home.

🌱 Power Moves — Small actions, more agency

Power Moves helps users discover manageable steps toward household and community resilience.

These can range from preparing essential devices for an outage to participating in local energy decisions.

Rather than overwhelming people with everything they could do, matcha helps them find something meaningful they can do today.

How we built it

I built matcha solo during the Stanford Cleantech Hackathon using Lovable, React, and TypeScript.

The application brings together multiple sources of environmental and energy information:

• Open-Meteo: Local weather forecasts.
• National Weather Service: Official weather alerts.
• EPA AirNow: Air quality information.
• Cal OES: Utility-reported power outage incidents.
• Lovable AI Gateway: AI-assisted Power Brew narratives.
• ElevenLabs: Audio narration.
• Leaflet and OpenStreetMap: Geospatial visualization.
• Custom TypeScript logic: Personalized Power Move prioritization and backup-power sizing.

An important architectural decision was separating AI-generated explanations from deterministic engineering calculations.

AI helps make complex environmental information easier to understand. Engineering rules calculate energy requirements and evaluate whether backup solutions meet household needs.

Challenges we ran into

Making climate information useful without making it frightening

I didn't want matcha to become another source of climate anxiety.

The challenge was creating a calm, reassuring experience that communicates meaningful risks without overwhelming people or making unsupported predictions.

Bringing fragmented data together

Weather forecasts, air quality measurements, and power outage reports come from different agencies, with different geographic coverage and update frequencies.

Making that information feel like one coherent household experience required careful prioritization and design.

Personalization without overpromising

Household resilience depends on location, personal priorities, essential devices, and financial circumstances.

I had to distinguish between what environmental data can reliably tell us and what requires more detailed property-level or household information.

Building solo under a tight deadline

With limited time, I had to make trade-offs between features, technical integrations, design, and testing.

I prioritized a working experience that connects information to action rather than attempting to build every possible climate resilience capability.

Accomplishments that we're proud of

I'm particularly proud of building a functional consumer climate resilience prototype as a solo hacker.

A few highlights:

• A complete user journey: From a localized Power Brew to personalized Power Moves and household backup-power planning.
• An approachable product experience: A wellness-inspired interface designed to make climate information feel accessible rather than intimidating.
• Real environmental data integrations: Bringing weather, air quality, official alerts, and reported outages into a single experience.
• AI with engineering guardrails: Using AI for accessible communication while keeping backup sizing grounded in explicit calculations.
• Accessibility through audio: Making Power Brew available as a narrated briefing.
• A consumer-first approach: Designing for renters, homeowners, and people who aren't ready to make expensive clean energy investments.

Most importantly, I built something I would genuinely want to use myself.

What we learned

My biggest learning was that more climate data doesn't necessarily make people feel more prepared.

We have increasingly sophisticated climate models, risk assessments, and energy technologies. But translating that intelligence into a practical household decision is a different challenge.

I also learned that climate adaptation doesn't always begin with an expensive purchase.

Sometimes it begins with identifying which devices your family needs during an outage, understanding local weather conditions, or participating in a community energy decision.

And while AI can make technical information more approachable, it needs to be paired with reliable data, transparent calculations, and thoughtful product design.

The real opportunity isn't simply delivering more climate intelligence. It's helping people develop the agency to act on it.
