Despite the abundance of renewable energy resources in Australia, and huge growth in solar and wind farms, along with hydro, getting it into our cities and households is still a challenge. An old, complex energy grid, our island nation status and the complexity of demand vs supply mean we still have some work to do. But Monash engineers and scientists are confident we can solve these problems. Behrooz Bahrani works on grid integration - how we get all the valuable energy produced by Australia’s sun, wind and waves into the grid and powering our houses. Roger Dargaville is researching pumped hydro and explains how it can help take us all the way with renewables.
