Abstract: Biogas production from animal manure produced in farms in the Canary Islands may represent an additional energy source for producing heat and/or electricity. Data of different animal farms distributed all around the islands were used for evaluating the potential biogas generation and contribution to the production of renewable energy in the Canary Islands. Total manure production is 495,622 tons per year. Results show that animal manure as a source of biogas may be associated with an overall biogas potential of 27.1 Mm3 year−1 with an equivalent installed power capacity of 6.8 MWe. Considering 0.5 t day−1 manure as the lowest limit for implementing biogas projects, 546 farms raising different animal types (poultry, sheep, swine, cows or goats) have potential for producing and using their own biogas for generating heat and/or electricity with electrical powers ranging from 3 to 185 kWe. Potential GHG emissions savings due to the production of biogas from animal manure could reach yearly 55,745.1 tons of carbon dioxide equivalents, including both substitution of fossil fuels and appropriate management of animal manure.
