The world just passed a huge solar milestone: three trillion watts of power
The last decade and a half has been monumental for solar power. The world first crossed the 100-gigawatt mark in 2012, and by 2022 had deployed 1 terawatt — or one trillion watts — enough to meet all U.S. power demand at its peak.
Now, in 2026, the world has reached 3 terawatts, with experts seeing no sign of rapid solar deployment slowing. Experts forecast that global solar capacity will exceed 9 terawatts by 2036.
So far, high-income countries have accounted for the lion’s share of solar deployment, while photovoltaics have remained too expensive for many low- and middle-income countries. But in recent years, Pakistan, Nigeria, and the Philippines have seen huge growth in rooftop solar, and forecasters expect more of the world to benefit from the cheapest source of electricity.
Even better: The rapid uptake of solar power is often followed by a “battery boom,” as lithium-ion batteries store excess electricity during the day and release it at night. Data shows that in low-income countries such as Pakistan and the Philippines, battery adoption surges soon after solar takes off.
Hunger has declined globally for three consecutive years
According to the latest report from the United Nations, an estimated 645 million people faced hunger in 2025. While that’s still a heartbreakingly high number, it’s 14 million fewer than in 2024, and 43 million fewer than in 2022.
It’s the third consecutive year hunger declined globally, after surging during the COVID-19 pandemic, though hunger levels are still higher today than they were in 2019.
An estimated 7.8% of the global population experienced hunger in 2025, down from 8.1% in 2024 and 8.6% in 2022 — demonstrating that progress is possible, and we must continue to make it.
