A new report published today (15 November) by the World Meteorological Organization and the World Trade Organization points to the role that trade can play to help supply meet demand for electricity from renewable sources. Launched at the 29th UN Climate Change Conference (COP29) in Baku, this first joint WMO-WTO report underscores how interconnection projects can tap into supplies of hydro—, solar— and wind-generated energy from regions with comparative advantage in renewable electricity generation and help to bring down the cost of the transition to low-carbon energy.
