Fred Lambert reports via Electrek: As part of a state initiative, Tesla deployed over 300 Powerwalls in schools to cool down hot classrooms in Hawaii. Hawaii has a problem with hot temperatures in public classrooms that is affecting students negatively. The problem was so significant that the Hawaii State Department of Education had to intervene. They put together a $100 million fund, which has already helped cool down 1,190 classrooms to date, with contracts set for more than 1,300 classrooms, according to The Garden Island. In order to roll out the program without significantly increasing energy costs for public schools, they partnered with Tesla to pair Powerwalls with solar power to reduce the impact of running the air conditioners in classrooms across the state. It also resulted in an interesting learning opportunity about renewable energy and energy storage for students.
