Less than a week after President Trump pulled out of the Paris agreement, at least ten state governors and the mayors of more than 200 American cities had recommitted to the climate accord’s emission standards. But Hawaii was way ahead of the curve — the state passed a law enforcing even stricter clean energy standards back in 2015. And they did it to save money.
Life in Hawaii looks pretty good, but there’s a challenge to living on an island in the middle of the pacific. It’s expensive. And nothing is more expensive than energy. Ninety percent of Hawaiian energy comes from fossil fuels and 100% of that needs to be imported.
An average Hawaiian family can pay up to $600 a month in energy bills. So Hawaii’s governor has set a goal: to power the island completely with renewable energy by 2045.
Getting off oil by 2045 will take wind turbines, volcanic energy, bio-mass recycling, and ocean energy. But Hawaii’s biggest power source will be solar. The trouble is, a sunny day in Hawaii is so sunny, the electrical grid can’t handle all the solar power that is captured, So the state’s opening giant battery fields. Meanwhile, Tesla is building the world’s largest battery factory.

If you want to see a quick idea of how solar panels are put together in less than 5 minutes then this is the video for you… Aquatooth.com is owned by Simon Bradley who’s a true expert at everything to do with renewable energy technology – from QC to designing systems. Thanks for inviting me along to the factory that day, Simon! The footage was shot on two iPhone 4′s and a little Canon Ixus 210 camera during a couple of visits to the factory with no idea of making a video originally – but I just started playing around with it and here it is.
