The rapid expansion of solar energy across Africa and developing Asia is significantly accelerating the proliferation of smartphones and social media, fostering digital inclusion in previously underserved regions. This energy transformation is occurring amidst ongoing, yet complex, demographic shifts in these continents.
Solar power is emerging as a cornerstone of energy access in Africa and developing Asia. Africa, holding 60% of the world's best solar resources, is poised for substantial growth, with projections indicating a 42% surge in its solar market by 2025. In 2024, 21 African nations generated at least 5% of their electricity from solar, with seven surpassing the 10% mark. Similarly, off-grid solar PV applications have seen cumulative growth in developing Asia, providing a decentralized solution to energy needs.
This energy access directly fuels the digital revolution. Off-grid solar solutions, often coupled with mobile payment systems like Pay-As-You-Go (PAYG), enable millions to charge smartphones and access the internet, bridging the digital divide. As one social media user noted, "Massive growth of solar energy in Africa & developing Asia will greatly aid in proliferation of smartphones+social media to those last corners of last countries without 100% penetration." This synergy allows communities without traditional grid access to connect, fostering economic activity and social interaction.
However, the tweet also touched upon population growth, stating, "Those concerned about African/developing world population growth should not as it will end." While fertility rates are indeed declining globally, United Nations projections indicate that Africa's population is expected to nearly quadruple by 2100, rising from 1.4 billion in 2023 to just under 4 billion. This significant increase is driven by a large young population entering reproductive age, creating demographic momentum that will sustain growth for decades.
In contrast, Asia's population, currently around 4.8 billion, is projected to peak around 5.3 billion by 2050 before experiencing a decline in the latter half of the century, potentially returning to current levels by 2100. The global population growth through 2050 is overwhelmingly concentrated in less developed countries, with over half coming from sub-Saharan Africa. This highlights a nuanced demographic future where different regions follow distinct trajectories.
The convergence of widespread solar energy adoption and increasing digital connectivity presents immense opportunities for development, education, and economic growth across Africa and developing Asia. While population dynamics remain a critical factor, the transformative power of renewable energy and digital access is reshaping the future of these regions.
