Paul gave a class in energy use to students at the Petit Plançó school in Olot. The students are working on interesting projects related to energy efficiency and energy in the home. The 12-year old learned about the large amount of energy we use every day, what this energy has done for us (air travel, long lives, time away from washing clothes by hand!), and why we need to transition to renewable energy. The students asked excellent questions about wind turbines, solar panels, and nuclear energy and were especially interested in the environmental impacts of renewable energies. The student engagement, concentration, and ability to follow the class (even though it was in English!) was fantastic, and also reflects how important the environment is to children.
