Global Solar Power Tops 2,000 TWh in 2024, Enough to Power All of India
Published · 3 min read
Solar energy crossed a historic threshold in 2024, generating more than 2,000 terawatt-hours (TWh) of electricity worldwide for the first time ever. That is more electricity than the entire country of India consumes in a year.
The milestone marks a turning point in how the world produces power, with clean energy sources now supplying more than 40 percent of global electricity generation.
A Record That Took Just Three Years to Reach
It took eight years for annual solar generation to grow from 100 TWh to 1,000 TWh. The jump from 1,000 TWh to 2,000 TWh happened in just three years, showing how fast the technology is scaling.
In 2024 alone, the world added 585 gigawatts (GW) of new solar capacity, a 30 percent increase over 2023 and more than double the installations recorded in 2022. Total installed capacity worldwide reached 2.2 terawatts by the end of the year.
Solar met 40 percent of the growth in global electricity demand in 2024, more than any other single energy source.
China Leads, but New Markets Are Rising Fast
China remained the dominant force, installing 357 GW of cumulative capacity and accounting for nearly 60 percent of new global solar capacity added in 2024.
But the geography of solar is shifting. India surpassed the United States to become the world’s second-largest solar market, more than doubling its capacity additions to 30.7 GW, up from just 12.5 GW in 2023.
Brazil ranked as the fifth-largest solar generator globally. The United States set its own record, adding 47.1 GW of new capacity to reach 224 GW in total.
Perhaps most surprising were the emerging markets. Pakistan imported 17 GW of solar panels in 2024, double the prior year, driven largely by consumers seeking cheaper alternatives to expensive grid power. Saudi Arabia imported 16 GW, also doubling its previous year’s total.
Emissions Avoided at Massive Scale
The environmental impact of the 2,000 TWh milestone is significant. According to researchers, the carbon emissions avoided by solar generation in 2024 are comparable to the entire annual output of the United States power sector.
A study published in Science Advances found that increasing solar output by just 15 percent across the U.S. could cut annual carbon dioxide emissions from power plants by 8.5 million metric tons, equal to taking nearly two million gas-powered cars off the road.
Clean electricity generation as a whole surged by a record 927 TWh in 2024, covering 96 percent of global electricity demand growth unrelated to temperature increases.
Storage Investment Races to Keep Up
The solar boom is driving parallel growth in battery storage. The world added a record 69 GW of new battery capacity in 2024, up from 41.5 GW in 2023. Global battery capacity has grown more than 12 times since 2020.
Costs have dropped sharply. Average battery prices fell from $511 per kilowatt-hour in 2019 to just under $213 per kWh in 2024, a decline of roughly 58 percent.
In California, battery capacity as a share of peak electricity load jumped from 6 percent in 2021 to 25 percent in 2024, reflecting how storage is being deployed to manage solar’s variable output throughout the day.
What Comes Next
Ember Energy is set to release its Global Electricity Review 2026, which will examine how solar and other clean energy sources are reshaping electricity systems worldwide. The findings are expected to show whether solar can maintain its record growth pace into the second half of the decade.
Analysts from SolarPower Europe project the world could be installing 1 terawatt of solar per year by 2030, roughly double the current rate, if investment and policy conditions remain stable.
