Photovoltaic technology, which harnesses the photoelectric effect to directly convert sunlight into electricity, has been in use since the late 19th century. Unlike in our timeline where it only saw widespread adoption in the late 20th century, in this alternate history the technology was developed and deployed much earlier, driven primarily by the needs of colonial empires rather than environmental concerns.
The photoelectric effect, the basic principle behind photovoltaic cells, was first observed and explained by Albert Einstein in 1905. By the 1880s, early prototypes of photovoltaic cells began appearing in laboratories across Europe and North America. The first reasonably efficient photovoltaic device was created in 1888 by Russian inventor Aleksandr Stoletov.
However, widespread practical application of photovoltaic technology did not occur until the 1910s, when it was rapidly developed and deployed by colonial powers like the United Kingdom, France, and Germany to provide electricity in remote outposts, research stations, and infrastructure projects in their overseas territories. This early adoption was driven not by environmental concerns, but by the need to power isolated settlements and military installations.
The ability to generate electricity directly from sunlight proved invaluable for colonial administrators and engineers. Photovoltaic systems were installed to power everything from telegraph stations and weather monitoring facilities to water purification plants and railways. This enabled a much faster spread of electrification to remote regions compared to traditional centralized power grids.
Massive investments in photovoltaic research and manufacturing by the colonial powers drove down costs and improved efficiency through the early 20th century. By the 1930s, photovoltaic systems were commonplace across the global South, enabling both critical infrastructure and quality of life improvements like lighting, refrigeration and communications for colonial subjects.
However, this rapid expansion also came with significant environmental and social costs. The mining of raw materials like silicon, gallium, and indium for solar cell production led to extensive resource extraction and habitat destruction in colonized regions. Meanwhile, the profits flowed back to the metropoles, exacerbating existing economic imbalances.
In the modern era, photovoltaic technology remains a major source of renewable electricity generation globally. Nearly two-thirds of the world's solar capacity is installed in the former colonial powers and their successor states. However, the technology's history and continued environmental impacts have made it a target of criticism and controversy.
Advocates highlight photovoltaics' advantages of zero emissions, modularity, and democratization of energy production. Critics argue that the long-term effects of mining, manufacture, and disposal of solar panels have been severely underestimated, leading to significant ecological damage and human rights abuses in the global supply chain.
Additionally, the legacy of colonial exploitation in the origins of photovoltaic technology fuels resentment and skepticism, especially in the global South. Decolonial and environmental justice movements have increasingly challenged the industry, demanding reparations, better working conditions, and a shift towards truly sustainable, community-controlled renewable power.
As the world grapples with the need to transition away from fossil fuels, the complex history and impacts of photovoltaic technology will undoubtedly continue to be debated. Its role in shaping the global distribution of resources, wealth and environmental costs remains a crucial and contentious issue.
