For decades the Navajo Nation powered the American Southwest. The coal under Black Mesa ran the Navajo Generating Station, 2.25 gigawatts that lit Phoenix, Las Vegas and Los Angeles, while thousands of Navajo families lived under the transmission lines with no electricity of their own. Brett Isaac grew up next to the Kayenta mine, in a family that worked in coal. As a kid he rode with his uncles to load trucks with coal for the winter, came home covered in black dust, and started wondering who was going to clean it up.

In his twenties he started putting solar panels on off-grid homes in his father's community of Shonto. About 200 homes later he co-founded Navajo Power, a Native-owned developer building utility-scale solar and storage on tribal land, with the Nation sharing in the ownership. Its Painted Desert Power project is 750 megawatts on nearly 5,000 acres, one of the largest solar and battery projects in the Southwest, and the first commercial lease for a utility-scale project on the Navajo Nation. Its residential arm, Navajo Power Home, has put solar and batteries on more than 600 homes, with a goal of 3,000 by 2031.

The first money behind it was not bank money. It was impact investors and foundations: Candide Group, the W.K. Kellogg Foundation, the Sierra Club Foundation, Halloran Philanthropies, the Schmidt Family Foundation, and sixteen CataCap donors who have put more than $360,000 into the Navajo Power fund.

In this episode:

•

The elder in Shonto who had no light bulbs, so the first proof her house had power was the refrigerator light, after years of keeping food on dry ice

•

Why coal workers were the most skeptical customers for off-grid solar, and what changed their minds

•

Nicole Horseherder, the Navajo matriarch and activist who was the toughest skeptic of Painted Desert, and how she became a supporter

•

The Turquoise Share: how Navajo Power gives communities equity in the developer instead of handing them a power plant and its liabilities

•

What Brett got wrong early on, and why eight years of development on tribal land opens the door for every other tribe

•

What he would tell a friend with a donor-advised fund who has never made an impact investment

Brett's line to remember: "Your light switch at some point is tied to one of our facilities."

Tracey Turner has spent three decades proving that the best answer to poverty is often a business. She started at Grameen Bank in Bangladesh, founded MicroPlace, one of the first online platforms that let everyday Americans invest in microfinance (later acquired by eBay), and founded Copia, which turned 52,000 small shopkeepers across Kenya into e-commerce entrepreneurs and hubs for their communities simultaneously increasing their financial earnings 2-3x.

Today she is early to an exciting new way to use philanthropy. She invests a meaningful share of hers in early-stage companies in East Africa, in the cause she cares about most: lifting people out of poverty. When those investments return capital, it goes back into her charitable account to be invested again, multiplying the impact of every dollar she gives.

This conversation is a field guide for anyone with a donor-advised fund, a foundation or an annual giving budget who wants their money to do more. Tracey takes us to a roadside shop in rural Kenya where a woman named Teresia doubled her income and sent her kids to school, and to a hillside near Mombasa where six women farmers may become the country's first coastal cocoa growers. She explains what she looks for in a founder, why she goes to see every business in person, and why the fact that less than 1% of global venture capital reaches Africa is the opportunity, not the obstacle.

In this episode:

•

Why Tracey thinks of her philanthropy as capital, and how the returns get recycled into the next investment

•

The criteria she uses to back an entrepreneur

•

What she learns on the ground that never shows up in a pitch deck

•

How a DAF can fund for-profit social enterprises, and what to check in the fine print

If you give generously and have ever wondered whether your philanthropy could work harder, this is the episode to start with.
