Renewables for accordion solo is a commission by The Finnish Association for Accordion Teachers for the 50th anniversary of the children's accordion competition "Minä Soitan Harmonikkaa" - "I Play Accordion". The competition has three age categories, C for musicians who are 10–11 years old, B for 12–13 year old players and A for 14–16 year old accordionists. Renewables consists of 8 pieces of which the first three are suitable for category C, pieces 4–6 are suitable for category B and the last two pieces are for category A. Renewables is also composed so that it can be performed as a suite with eight movements. Renewables is inspired by different forms of renewable energy: wind, waves, rain, sun, tide and geothermal heat.
