Scenario 3: Urban-rural mutual cooperation
In this scenario (Fig. 7.8), both urban and rural areas take an equal role in the
local energy system. Natural resources in the local area are expected to be fully
exploited as the main energy carrier to serve local energy requirements. Nevertheless, in order to guarantee consistent energy service, connection to local
utilities remains necessary.
7.4 Energy Technology Options
As important input data for a bottom-up optimization model, technical information
regarding both electricity and heat generation are assumed according to previous
studies, as shown in Table 7.1 (Kojima et al. 2007; Nagata 2009; NEDO 2010; Ruan
et al., 2009; Xu, 2008). Wind power and hydropower are not included in the
following analysis due to local topographic conditions.
