Residents in north-east China are experiencing unannounced power cuts, as an electricity shortage which initially hit factories spreads to homes. Philippe Benoit at the Center on Global Energy Policy at Columbia University, explains why this is significant. Also in the programme, Germany's centre-left SPD party has claimed victory in the federal election. Parties will now try to form a coalition government, the BBC's Victoria Craig in Frankfurt assesses what the outcome of the vote means for the German economy. We discuss urban reforestation across the globe and the impact of latest wildfires in California. Plus, regular contributor Peter Morgan asks whether it's time for greater transparency in the workplace about how much money people are paid.

All through the show we're joined by Alison van Diggelen of Fresh Dialogues in Silicon Valley.
