Hawaii's utility-scale electricity generation from solar energy more than doubled in 2014. Hawaii generated 29% of its renewable electricity from both utility-scale resources and small-scale solar photovoltaic panels installed on rooftops across the islands. Hawaii is the first state to set a goal of producing 100% of its electricity from renewable energy sources. The state plans to reach that goal by 2045.
The bad news is that the majority of renewable energy is hydropower, which is not an exponentially improving technology. The good news is that solar energy is an exponentially improving technology, growing 30% a year in the US. If this continues, solar installations, which just hit one million in Q1 2015, will account for virtually 100% of US electricity production, according to Stanford's Tony Seba.
