Consumers in Germany and the UK are growing more curious about rooftop solar and electric vehicles as they seek to shield themselves from surging energy prices resulting from the Iran war.

Octopus Energy, the UK’s biggest energy supplier, said inquiries about home solar were 27% higher than average the week the war started, while German companies also reported a rise in interest. Data on actual sales won’t be available for a few months.
