5. Results and discussion
Sectorwise energy demand and resource potential compiled in the following section are based on the detailed investigations carried out earlier [27–30,35–37,39–42].

5.1. Energy demand

Compilation of survey data and sectorwise analyses show that noncommercial sources of energy, such as, firewood and agricultural residues are the major components in the districts energy consumption. Table 1.1 lists sectorwise energy demand based on detailed investigations carried out in various sectors of Uttara Kannada district. It shows that the domestic sector with 77.96% (8941.56 million units-mkWh) of total energy consumption, is the major energy consuming sector followed by industrial (15.93%) and agricultural (5.13%) sectors. This is illustrated in Fig. 3.1.

Tables 1.2 and 1.3 give sourcewise consumption of energy. Uttara Kannada district mainly depends on noncommercial energy sources (96.23%), such as, firewood (78.09%), dung in the form of biogas (13.12%), and animate sources (5.02%). While, commercial sources, such as, electricity (2.86%), kerosene, diesel, petrol, etc., (0.90%) and LPG (0.0001%) constitute 3.77% of total energy consumption in the district. This is illustrated pictorially in Figs. 3.2 and 3.3, respectively. Sourcewise and sectorwise consumption of energy is listed in Table 1.4. Domestic (77.67%), industrial (13.535%) and agricultural (5.024%) sectors mainly depend on noncommercial sources of energy. This aggregated information is depicted in Fig. 3.4. Energy demand of various sources in the district is listed in Table 1.5.
