    • Letting in the Light: How solar photovoltaics will revolutionise the electricity system

      Solar photovoltaic (PV) power generation is poised to revolutionise the electrical system in countries around the world. From around 2% in 2016, the share of global electricity generated from solar PV to grow to as much as 13% by 2030, according to this report from the International Renewable Energy Agency (IRENA). The solar industry’s expansion is driven primarily by cost reductions, with the report anticipating further cost declines by up to 59% in ten years.
