WASHINGTON (AP) — World leaders have joined President Joe Biden at a virtual climate summit to share their stories about how nations can break free of climate-damaging fossil fuels. The summit showcased Kenyans leapfrogging from kerosene lamps to geothermal power and Israeli start-ups scrambling to improve battery storage. Friday’s second and final day of the summit also focused on what Biden says is the need for massive investment for cleaner energy — and what he says is the economic payoff. Biden called it time to rebuild economies now for better economies for the word’s children and grandchildren.
