This special stamp issue by Australia Post illustrates the diversity of renewable energy production in Australia. Energy production using sustainable sources is generally safer and cleaner than production using fossil fuels, such as coal, oil and natural gas. The stamps feature some of the sustainable sources where renewable energy is produced – sun (solar), wind, water (hydro) and organic matter (biomass).
