Europe's drought has reduced water levels on the Danube, causing headaches and lost income for companies generating electricity from hydro, coal-fired and nuclear power plants.
We travel down the river, stopping off in Austria, Hungary, Serbia and Romania to look at how each country is dealing with the challenges and what ordinary people are doing to help.
