How One Old Car (and an AI) Helped Put More Solar on the GRID

I set off to donate a used car to charity. Somewhere between “public radio station” and “radical climate litigation,” I landed on GRID Alternatives, a nonprofit that puts solar on roofs in underserved communities while training people for clean‑energy jobs.

How I went from “some charity” to GRID Alternatives

I’d tried to donate my old car to Houston Public Media, and… nothing. No follow‑up. So I started looking for a better cause to donate to. On a lark, I decided to see if my AI could come up with any good choices. (I like to say “my AI”. I use Perplexity.ai which I think is pretty decent. It’s an aggregator of different AI models. Check it out.)

I told the AI some of the topics I was interested in donating to: high‑impact, well‑rated organizations, that do work at the community‑level.

The AI gave me a respectable first batch of suggestions: veteran car‑donation programs, education‑focused car charities, and immigrant‑rights orgs that take vehicles. Good start—but I got to thinking about climate change, so I also wanted this donation to lean into climate-related causes. So began my journey down the rabbit hole.

Isn’t using power-hungry AI to donate to climate solutions a bit ironic? (click triangle at left for more on this)

Yes, AI uses a lot of electricity. And yes, I used AI to figure out where to send a car so it could fund climate solutions. That seems contradictory at first glance, but it helps to think of costs as different from leverage.

On the cost side, large AI models run in power‑hungry data centers. Training and serving them is not free in climate terms. The energy footprint is real and growing.

On the leverage side, AI is already doing useful work for the transition we actually need:

• Helping grid operators forecast and balance alternative energy output and demand
• Optimizing where and how we site clean‑energy projects
• Improving energy efficiency in buildings and industry
• Accelerating research on batteries, materials, and next‑gen clean tech

Used well, AI can speed up the clean‑energy transition and make existing infrastructure work harder and smarter.

So the question isn’t “pure or hypocritical?” It’s: does the benefit of using AI in a given case outweigh its marginal energy cost? In this context—using a handful of queries to redirect a whole car’s value into community solar and workforce training — the climate and equity impact of that decision dwarfs the energy used to ask the questions.

The job now is to push for both: AI that runs on clean energy, and AI applied to problems (like climate and resilience) where it clearly has an impact.

The actual prompts I used along the way

To use AI effectively, you need to think of it as a conversation with a rigid, but all knowing oracle. The more questions you ask, the closer you get to information that is actionable for your particular needs.

Here’s a pared down sequence of questions I ended up asking the AI, which you can steal and adapt to your own use:

• “I have a used car to donate… other worthy causes in Houston and beyond? I am interested in donating to organizations with high ratings for effective work, community level, veterans, early childhood education, immigrant rights.”
• “How about scholarships for underrepresented groups?”
• “Any other ideas? STEM education would be a good one. Helping veterans is still up there.”
• “Tell me more about Workshops for Warriors.”
• “Another thought, any programs training vets or others to install wind turbines, solar panels, etc.?”
• “Besides what we have discussed above, how about any orgs that help communities switch to alternative energy or adapt to climate change?”
• “Do any of these non‑profits in this space take car donations directly?”
• “GRID Alternatives sounds pretty interesting.”

That list is basically a blueprint for turning “help me donate a car” into “help me align this donation precisely with my priorities.” This conversation took all of about 15 minutes.

From STEM and veterans to clean energy and communities

Once I started layering in STEM and underrepresented groups, the AI brought in:

• STEM nonprofits for girls and minority students
• Scholarship orgs for underrepresented students in engineering and science
• Workshops for Warriors – a veteran‑focused advanced manufacturing school

Workshops for Warriors was tempting: veterans plus solid technical careers. But I realized I wasn’t sure how future‑proof those skills are compared to clean‑energy jobs.

That thought pushed the conversation toward renewables‑specific training. So I asked about organizations that help communities switch to alternative energy or adapt to climate change. That’s when things started coming into focus.

The moment GRID Alternatives rose to the top

Once the AI pulled in community‑focused climate and energy nonprofits, GRID Alternatives immediately stood out:

• They install solar for low‑income households, Tribes, and community projects.
• Their installations double as hands‑on job training for people from underrepresented backgrounds trying to get into the solar industry.
• They sit squarely at the intersection of climate change mitigation, adaptation, and equity.

At the same time, me and my AI also talked about:

• Extinction Rebellion and 350.org – direct‑action climate movements, more disruptive and confrontational.
• Earthjustice and the National Resources Defense Council (NRDC) – legal and policy heavyweights with stellar charity ratings.

The AI made a nice table for me to compare the different options…

Organization	Main focus	Charity rating snapshot	Approx. % to programs	What my car would effectively fund
Earthjustice	Environmental law & litigation	Top‑rated; long‑running 4‑star status on major watchdogs	~80–85% programs, remainder admin/fundraising	High‑impact lawsuits shaping climate, air, and water rules.
NRDC	Policy + litigation on climate, energy, health	Top‑rated; ~97% overall scores on Charity Navigator‑type metrics	~80–85% programs	Policy, legal work, and campaigns on climate and health.
GRID Alternatives	Community solar & workforce training in underserved communities	Featured as a strong sustainability/climate org	Majority to projects and training	Solar on low‑income homes and community sites plus solar‑installation job training.

For my car I wanted something I could imagine concretely: somebody’s A/C staying on during a heat wave, and somebody else getting real experience installing solar on a roof.

Vetting a charity before committing

Right before committing, we did a quick “trust but verify” pass:

• Financials – GRID has multiple years of Form 990s and financial reports publicly available, with the most recent year highlighted (2024 at this point, because nonprofit reporting cycles are usually a little over a year behind).
• Watchdog listings – They’re present and up‑to‑date in the usual nonprofit directories and rating sites, with no glaring red flags in revenue, spending, or governance.

How donating a car to charity actually works

The process is refreshingly dull and simple:

• GRID uses a national vehicle‑donation processor.
• You go to their “donate your vehicle” page.
• You fill out a form or call with…VIN, make/model/year, condition, and the address where the car is located.
• They arrange free towing, even if the vehicle is not running, as long as it’s towable and accessible.
• You sign the title over when the tow truck arrives and they tow it away
• The vehicle is sold at auction or to a buyer; net proceeds go to the charity you specified.
• You get:
  • A thank‑you letter that doubles as a tax receipt
  • A formal IRS form if the sale price is above the reporting threshold (usually around $500)

And that’s it. Your ancient fossil‑fuel asset becomes a small, targeted contribution to a climate‑justice‑and‑adaptation project.

Because my car wasn’t running and the engine was seized up, it probably ended up at a pick a part place – a “junkyard” where you go to pull parts yourself.

When I was a bit younger I had an old Toyota 4-Runner and would go to the junkyard to get various parts, cheap. It’s actually a lot of fun to do that! You bring your own tools and they give you a basket, you go wander out in the field of cars, find one close to your model and harvest the replacement part yourself.

Part harvesting is also climate positive as it keeps older cars running (the carbon cost of a new ICE vehicle is higher than getting a long lifespan out of an older ICE vehicle) and reuses parts (no carbon used to manufacture new parts).

PS. That old 4-Runner was also donated to charity after it gave up the ghost at 251,000 miles!

How to copy this process

If you’re like‑minded and you’ve got a used car to offload, here’s a distilled version of the process you can follow.

1. Pick your impact lane before picking the nonprofit

Write down your top one or two types of charitable impact you’d like to have.

2. Use AI for iterative narrowing, not one‑shot answers

Don’t just ask, “Where should I donate my car?” and call it good. Instead, chase it down like I did:

• Start with: “I want to donate a car to a nonprofit that [does X].”
• Then layer in your target actions or groups
• Keep going when results are close but not quite right, e.g.:
  • “This looks good, but how about [your impact of choice].”
  • “I want something closer to [a more specific impact of your choice!].”

The back‑and‑forth is the point! The AI is your guide, but you make the decisions.

3. Run a quick due‑diligence checklist

Before you hand over the title:

• Check that the nonprofit:
  • Has recent financials posted
  • Appears on at least one major rating/listing platform
  • Doesn’t have obvious governance or financial red flags
  • Confirm they have a car‑donation program (if you are donating a car! Otherwise, I am sure they’d appreciate cash too! 😉 )

4. If you care about climate adaptation and justice, look for GRID‑type models, or just go to GRID now 🙂

Specifically, look for organizations that:

• Put clean‑energy or resilience infrastructure in low‑income or frontline communities
• Pair that with workforce training or local capacity‑building
• Have clear, transparent finances and a track record of on‑the‑ground projects

If you have ever donated a car, you might think of it as a nice little tax‑deduction errand. But if you’re willing to have a slightly more insightful conversation with yourself—and with an AI—you can turn that errand into an intentional act of climate adaptation and justice.

In my case, that meant following the trail all the way to GRID Alternatives and saying: Yes. This is where this machine should end its fossil‑fuel life and start its climate‑justice afterlife.

You can do the same.
