Business
Sunny side up
Tesla, the Palo Alto maker of solar panels and electric cars, has put the final touches on a sprawling solar farm on the Hawaiian island of Kauai. The farm means business: it is made up of some 50,000 panels that will be used to reduce the sunny island’s fuel consumption by a whopping 1.6 million gallons (more than 7.3 million litres) of petroleum each year. It’s the latest in a string of renewable-energy developments for Hawaii, which has traditionally been dependent on expensive imports of fossil fuels from the mainland but in recent years has pursued an ambitious green agenda. In 2015 it became the first US state to announce a 100 per cent renewable-energy target by 2045 and in January it struck a deal with AES Corp to build what will be one of the world’s largest solar-battery plants. The island is fast becoming separated from a mainland whose president still refuses to acknowledge that climate change is happening.
