The 1970s oil crisis once again changed the dynamics of the energy market. New products became available – methane in particular – and F.lli Ceresa invested in these alternative energy sources for heating management, developing new professional capacities to meet the evolving needs of the sector. The old oil furnaces were steadily replaced with new, more economical, cleaner heating systems. A new F.lli Ceresa S.p.A. logo was created – a shield with a stylised sun, symbol of universality and energy – signaling a precise strategic choice and a new business reality. Diversified energy services were added alongside the traditional distribution of fuel products: engineering, installation and operation of heating plants. • 1980: integrated energy services Photos: 1.
