The second highest emitter of CO, from fossil fuel combustion is the power sub-sector, which has contributed 27% in 2000. According to the published future electricity generation plan of the Ceylon Electricity Board (CEB), Sri Lanka's CO, emission from this sub-sector will show a rapid growth in view of coal power becoming the main source of electricity in the near future. The government has also declared that at least 10% of the electricity supplied to the national grid should come from non-conventional renewable energy (NCRE) sources by 2015. The CEB has also announced a NCRE scenario through which it plans to increase the NCRE installations by about 600 MW by 2020. Currently, about 4% of the electricity generated comes from these sources and considering the large number of applications received from investors for NCRE project approvals, it is very likely that this target could be achieved, if not more. It is estimated that a 28% saving of CO emissions between the BAU and the NCRE based scenario could be achieved by 2020 in the power subsector.
