A solar panel, a wind turbine and a hydro dam are all getting to know each other.

‘What kind of music are you into?’ asks the dam. ‘I’m into trance’, replies the solar panel. ‘Ooh, too intense for me’, dam says, ‘I much prefer classical melodies, maybe a little 60s soul at the weekends.’ ‘What about you Mr Turbine? What are you into?’ ‘Me?’ He replies, ‘I’m a huge metal fan.’
