The present pilot study examined the potential of tobacco (Nicotiana tabacum L.) as an energy source. The fresh matter of whole tobacco plants, the yield of dry matter of stems and leaves, as well as the higher heating value and methane production potential from tobacco biomass were determined. The yield of tobacco leaves was on average 4.69 Mg ha−1 (dry matter) and 76.90 GJ ha−1 yr−1 (biomass energy yield). Tobacco stems yielded on average 8.55 Mg ha−1 and 150.69 GJ ha−1 yr−1, while yields of whole tobacco crops were (on average) 13.24 Mg ha−1 and 227.59 GJ ha−1 yr−1. Methane potential of tobacco plants was (on average) 248 Nm3 Mg−1 VS (volatile solids). The tobacco plants tested in the study could be used as energy crops as their dry matter and energy yields are similar to those of the most popular energy crops being currently used in biomass production in Poland and the European Union. Nevertheless, further studies to choose the Nicotiana species and varieties most suitable for energy production and to assess the cost-effectiveness of tobacco biomass production are needed.
