Harri has just finished her engineering degree at university. She studied how the weather affects how much energy wind turbines can capture.
Harri is curious to find new ways for people to use renewable energies in their everyday lives!
She just started her first job in an engineering company which produces batteries for hearing aids. In her new job, she studies which are the best materials to build batteries from, for different weather conditions. You might think you have cold ears, but batteries hate the cold even more than you do – so cold conditions can make hearing aids stop working.
“I really love this activity because you can put weights in the paper cup to see just how amazing wind power can be!”
