The share of renewable energy that achieved lower costs than the most competitive fossil fuel option doubled in 2020, a new report by the International Renewable Energy Agency (IRENA) shows. 162 gigawatts (GW) or 62 per cent of total renewable power generation added last year had lower costs than the cheapest new fossil fuel option. Renewable Power Generation Costs in 2020 shows that costs for renewable technologies continued to fall significantly year-on-year. Concentrating solar power (CSP) fell by 16 per cent, onshore wind by 13 per cent, offshore wind by 9 per cent and solar PV by 7 per cent. With costs at low levels, renewables increasingly undercut existing coal’s operational costs too. Low-cost renewables give developed and developing countries a strong business case to power past coal in pursuit of a net zero economy. Just 2020’s new renewable project additions will save emerging economies up to USD 156 billion over their lifespan.
