Puerto Rico: electricity in context
In 2025, Puerto Rico generated 20.3 TWh of electricity. That puts it in the same league as Mozambique. The biggest single contributor is oil with 47.6%; natural gas adds 29.5% and coal 16.5%.
Renewables supplied 6.4% of the electricity, which ranks Puerto Rico 135th of 158 countries (in the bottom quarter). That is 27 points below the world average of 33.8%. It is also below the average for North America (28.8%). Each kilowatt-hour emitted on average 655 g CO₂e, against a world average of 458 g. This is one of the more carbon-intensive grids in the world. In the cleanest-grid ranking, Puerto Rico is 138th of 158.
Since 2015, the fastest-growing source has been solar power: its output rose by 910 GWh, lifting its share by 4.5 percentage points. The biggest decline came from oil (−1.2 TWh). The net effect: renewables gained 4.6 percentage points of share since 2015. Total generation shrank by 630 GWh over the same period. Carbon intensity dropped from 681 to 655 g/kWh, a 4% cut.
Coal supplies 16.5% of electricity. That is roughly unchanged on 2015.
Solar (4.9%) and wind (1.1%) now add up to 6.1% of generation; the global figure is 17.3%. Per person, that is 309 kWh of solar electricity a year, versus a global average of 338 kWh. Wind adds 71 kWh per person. Solar first passed 1% of the mix in 2018.
Generation per person is 6,265 kWh a year, 1.6× the world average of 3,860 kWh. Puerto Rico does not trade electricity with other countries: the grid is not interconnected with any neighbour.
