Global GridLesotho's energy mix and electricity
🇱🇸 In 2022, Lesotho generated 0.48 TWh of electricity. Almost all of it, 100%, came from hydro. In total, 100% came from low-carbon sources (nuclear and renewables) and 0% from fossil fuels.
On average, each kilowatt hour produced about 21 grams of carbon dioxide (CO₂), far below the world average of 458 grams in 2025.
Electricity demand was 0.91 TWh. Lesotho imported 0.43 TWh more electricity than it exported, equal to 47% of its demand.
Since 2000, electricity generation has grown by 66%, from 0.29 TWh. The low-carbon share went from 100% to 100%. Carbon intensity fell from 34 to 21 grams per kWh.

Energy security score
Vulnerable. It is not ranked because its power system is very small. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 4 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for Lesotho, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, hydro, made 100%. | 0 |
| Little reliance on imported power Net imports were 47% of demand; each 1% takes off 2 points. | 5 |
| Low-carbon power Nuclear and renewables made 100% of generation. | 100 |
| Low gas and oil use Gas and oil made 0% of generation; the score is 100 minus that share. | 100 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
