What's a better problem for the consumer?
Engineers supported by modern-day technology having to grapple with the problem of too much clean energy from an inexhaustible source -- which no one controls -- or recurring shortages from the traditional sources and their ever-increasing costs that are controlled by monopolies operating with technology that is decades old?
"As customers generate more than they need and feed the excess back into the grid for others to use, it makes managing the system much more complex. What happens when a cloud passes over and dozens of rooftop units suddenly grind to a halt? What's to be done on a sunny autumn day, when rooftop solar systems are producing way more power than the grid can use?
Hawaii finds itself pushing the envelope not just because of its abundant sunshine. A bigger driver has been the state's reliance on oil to fuel its power plants. Oil is always more expensive than natural gas, but prices shot up even higher last year when Japan's nuclear disaster sent demand, and soon prices, skyrocketing on the Asian markets where Hawaii buys its supplies.
The state has set a goal of obtaining 40% of its power from locally generated renewable sources by 2030. Already, the Big Island has jumped ahead and is producing 44% of its power from renewable sources, and it could hit 100% by the end of the decade."
