  • BRUCE ASATO / BASATO@STARADVERTISER.COM
    Henk Rogers — the entrepreneur who made the video game “Tetris” famous — of Blue Planet Energy Systems has gone off Hawaiian Electric Co.’s power grid.

Rogers predicted that the uncertain future of rooftop solar in Hawaii, if NextEra buys HECO’s parent company, would push more people to go off-grid in the state.
