The International Energy Agency (IEA) has declared solar the “new king” of electricity, arguing that, while renewables technologies as a whole are poised for rapid growth over the coming several decades, solar will be “at the centre of this new constellation of electricity generation technologies”. The agency’s ‘World Energy Outlook 2020’ notes that, with sharp cost reductions over the past decade, solar photovoltaic (PV) is now consistently cheaper than new coal- or gas-fired power plants in most countries, while solar PV projects now offer some of the lowest cost electricity ever seen.
