Ask Americans which state is the greenest, most unspoiled, most eco-conscious place in the country, and a lot of people would probably say Hawaii. So it may come as a surprise to learn that Hawaii is actually the most oil-dependent state in the nation. Because it’s unreachable by trains or pipelines, the state spends $5 billion a year importing oil. As recently as 2003, more than 90 percent of their electricity came from foreign oil. That’s not just bad for the environment; it’s bad for consumers: Hawaii residents pay the highest electricity rates in the nation.That could all soon be changing, however. Thanks to sweeping legislation adopted last year, Hawaii has set a goal to become the first state in the country to generate 100 percent of its electricity from renewable energy resources. If it’s successful — the 100 percent goal has a deadline of 2045 — Hawaii would move from worst to first on clean energy. To call the plan ambitious would be an understatement. Getting to a completely renewable portfolio requires not only new investments and new technologies, but also a complete overhaul of the energy industry in the state. But the truth is that Hawaii has already made notable strides in reducing its dependence on fossil fuels. Thanks to a committed effort over the past 15 years, the state has decreased its dependence on oil by about 20 percentage points from that 2003 high.
