By the dawn’s early light

Electrification

The dawn of electrification

In October, we launched our 250 years of US innovation series with a focus on the transcontinental railroad. This month, I’m excited to present the second edition, featuring the dawn of electrification.

The incandescent lightbulb was a bright idea that sparked electrification. After nearly 3,000 prototypes, Thomas Edison created an incandescent lightbulb in 1879 with a carbonized cotton-thread filament that burned for 13 hours. His invention would receive US patent number 223,898 on 27 January 1880. Perhaps unsurprisingly, Edison got his start working in the growth industries of his era: railroads and telegraphs. Some of those early experiences spurred him to tinker and experiment to find new innovations, like the quadruplex telegraph that enabled four messages to be sent simultaneously. The same curiosity that spawned the lightbulb led to less well known but equally important advances in power distribution like generators, meters, and wiring switches. His overall approach to invention and entrepreneurship would inspire an entire new school of thought, embodied by people such as Henry Ford.

The lightbulb was a revolutionary invention, but it took more than a decade for electrification and its benefits to become essential for businesses and households—a necessity that sparked a wave of follow-on inventions. By the early 1900s, when electricity was just beginning to power commerce, the benefits of the telegraph and the transcontinental railroad were also becoming more entrenched. Productivity would rise rapidly in urban areas before climbing nationally in the 1920s as these transformational technologies reshaped the industrial and agricultural landscape. Electrification would spur yet another wave of productivity growth in the 1950s with the invention of household appliances.

Today, electric utilities are experiencing another significant growth phase—this time to power artificial intelligence (AI) and the energy needs for reshored manufacturing and electrification. Investors must now reconsider the electric utility sector, as its performance profile appears slightly less defensive and is instead powered by structural growth in revenues and earnings resulting from electrification and AI. In other words, the sector is experiencing accelerating power demand growth and investment like its dawning in the early light of the 1900s.

From sea to shining sea

The transcontinental railroad

The spirit of enterprise

“No sooner do you set foot upon the American soil than you are stunned by a kind of tumult,” wrote Alexis de Tocqueville, taken by the pace of a young republic, in 1835’s Democracy in America. I, too, was stunned. Like Tocqueville, having been educated in Europe, America appeared to have turned things upside down. The question of “why could it work?” rather than “why will it not work?” seemed reckless yet enticing.

For the first time as a young professional, I stepped onto American soil in 2000 for a narrowly defined purpose—a project involving data, analytics, and a new way of systematic equity investing—much like Tocqueville, who crossed the Atlantic in 1831 under the banner of studying the US penitentiary system. I did not expect, however, to be swept into the same whirlwind that struck Tocqueville nearly two centuries earlier. 

Everywhere I turned, I witnessed what Tocqueville described as “the spirit of improvement always abroad in the United States.” In conversations with investors, business leaders, and start-up entrepreneurs, I encountered the same impatience with the present. I saw associations—what Tocqueville had once described as “the art of pursuing in common the object of their common desires”—not only in civic groups but also in venture capital and incubators.

This passion, still vivid today, extends beyond material wealth. It is about impact, legacy, and the drive to leave something behind that is bigger than oneself. While I came to America for a project, I stayed because of this restless, inventive spirit that is part fever, part discipline, and part collaboration.

The almost 250-year history of the United States stands as a testament to the power of its unique democratic and societal spirit of entrepreneurship. Leading up to 4 July 2026, we will celebrate the semiquincentennial with a series of reports highlighting prime examples of uniquely American innovation and entrepreneurship that have not only transformed the US economic landscape but also impacted the world in profound ways. 

I’m delighted to share our inaugural report, which takes us back to the mid-1800s and the building of the transcontinental railroad. This significant and foundational innovation revolutionized transportation and commerce, but only after overcoming numerous logistical and geographic challenges.

Transformational innovation has been an engine of US economic growth since the nation’s founding and is one of the three perspectives that shape our investment views. A review of the past—the capex cycles, capital flows, productivity booms, and wealth creation—suggests many parallels to what lies ahead, especially in the areas of AI, electrification, and longevity. This arc is what fascinates me most: the chance to learn from history in order to guide portfolios through the next wave of structural change.

The transcontinental railroad, completed in 1869, revolutionized American society—it dramatically reduced travel time, lowered costs, and enabled economic expansion. Key “before” and “after” data illustrate the railroad’s transformative impact on transportation, industry, and settlement. From transit time traversing the continental US to population growth in the West, these figures showcase the scale of American innovation and infrastructure development.
