Visitors to Sensation science centre in Dundee were learning about energy at the weekend.

Futuristic Energy is a 20-minute show that explores what energy is, why people need it, where it comes from and how future requirements might be met.

It also examines renewable energy, including wind and solar power, and looks at hydrogen and its potential.

The show, repeated throughout the day, is included in the admission price and runs until October 26, with further details on 01382 228800 or at www.sensation.org.uk.
