In 2005, while flying around Western Australia's countryside for the government, connecting solar energy batteries to microgrids, he encountered a major problem: Cheaper batteries encouraged people to go off-grid, hiking up prices for everyone else. Electricity was already pricey, and with fewer people contributing to the grid, it grew even more expensive.<br><br>He crossed paths with [ Jemma Green], his future Power Ledger co-founder, through various solar energy conferences. She was a "disenchanted merchant banker" who'd moved back to Perth in 2013 after 11 years in the UK.
