Recent analyses suggest that harnessing solar energy from a fraction of the Sahara Desert could meet global electricity demands. Covering approximately 1.2% of the Sahara’s 9.2 million square kilometers—equating to about 110,400 square kilometers—with solar panels could generate an estimated 22,080 terawatt-hours annually.

This output aligns closely with the world’s total electricity consumption, which was approximately 23,000 terawatt-hours in 2021.

The Sahara’s high solar irradiance and vast, uninhabited expanses make it an ideal location for large-scale solar farms. Implementing such projects could significantly reduce reliance on fossil fuels and contribute to global carbon emission reduction efforts.

However, logistical challenges, including the construction of extensive transmission infrastructure to deliver electricity to distant regions, present significant obstacles. Additionally, environmental concerns arise, as large-scale solar installations could alter local climates and ecosystems.

Despite these challenges, advancements in solar technology and international cooperation could make the Sahara solar initiative a viable component of the global renewable energy strategy. Ongoing research and pilot projects continue to explore the feasibility and potential impacts of such endeavors.
