Costa Rica has used 100% renewable energy for over 115 days. They are the first country to do it.
They are now aiming for a year without any fossil fuels. Many countries in the world are following Costa Rica’s example. In Europe, Sweden leads with over 50% of their energy coming from renewable sources. The UK is nearly at 6% by comparison. Scotland was able to provide 106% of its renewable energy requirements for a single day.
Hydropower is the most reliable source for the Latin American nation. That’s because of the large river systems and the heavy tropical rainfalls.
