Tanzania
TZATanzania's grid has been getting dirtier, not cleaner.
Low-carbon electricity went from 79% to 33% in 20 years.
What this grid depends on
Three measures that say more about a country than how much power it makes. Open “what this means” on any of them if the term is new.
Cleaner than 6 in 10 grids worldwide.
What this means
How much planet-warming gas is released to make one unit of electricity. Two countries can generate exactly the same amount and one of them be ten times dirtier doing it. Lower is better.
Tanzania buys in more electricity than it sends out.
What this means
The share of the electricity used here that was generated abroad and carried in over high-voltage lines. The higher it climbs, the more this country relies on a neighbour to keep its lights on.
Also true of Tanzania
Gas overtook hydro on Tanzania's grid in 2011.
Today gas supplies 63% and hydro 32%.
Tanzania's electricity is cleaner than the world average.
345 grams of CO2e a kilowatt-hour against a world figure of 458 — 25% below.
Tanzania’s neighbours
UgandaUganda has about as many people as South Korea, and 104 times less electricity to share between them.
KenyaKenya is first in the world for geothermal.
Democratic Republic of CongoThe Democratic Republic of Congo has about as many people as Japan, and 57 times less electricity to share between them.
ZambiaZambia's grid has been getting more carbon-heavy, not less.
MozambiqueMozambique has about as many people as Saudi Arabia, and 23 times less electricity to share between them.
Figures are for 2024, the most recent year reported for Tanzania. Generation shares are a percentage of electricity generated, not of energy used. How this is calculated.
