Costa Rica has achieved a clean energy milestone by using 100 per cent renewable energy for a record 75 days in a row.

The feat was achieved thanks to heavy rainfall, which powered four hydroelectric plants in the first three months of the year, the state-run Costa Rican Electricity Institute said.

Last year 80 per cent of the energy used came from hydropower, while geothermal energy made up about 10 per cent of the mix in the volcano-strewn nation.
