Nice! This from the Telegraph (UK). Let's hope it keeps raining.
The Central American country, which has long boasted of its green credentials on energy policy, was able to achieve the milestone thanks to heavy rain in the first three months of the year.
Around four-fifths of its electricity supply comes from hydro-electric power, which was boosted by rainfall at four major dams.
Costa Rica is one of the most developed countries in Latin America, ranking above Italy and several other European Union countries in the annual prosperity rankings put out by the Legatum Institute, a think-tank.
Its environmental record may not be easily copied by other nations - its tropical climate with high rainfall, mountainous interior, and relatively low population of 4.8 million people give it an advantage in terms of renewable energy.
More than ten per cent of its electricity in some years is generated by geothermal projects operating from its string of active volcanoes. It also has wind, biomass and solar energy plants.
Tapping volcanic heat! How cool is that!
Additionally, it has a low heavy industrial base, with its economy relying on tourism, agriculture - particularly bananas and coffee - and an Intel microprocessor plant.
Last year, all but six per cent of its energy was generated renewably.
That figure should come down further when a new geothermal project, commissioned last year by the government at a cost of $958 million, comes on stream.
“It’s good news that more geothermal will be coming on board, as there are obvious downsides of being too reliant on hydro-power, especially run-of-the-river systems, which can be hindered by seasonal changes in water flow,” Jake Richardson, an analyst at Clean Technica, told Science Alert.
Back in the late 70's when I was living in Jamaica, I had an opportunity to visit Costa Rica, but went to Panama and then to Guatemala (where my brother Jim was in the Peace Corp) instead.
