Conversely, coal has played a relatively limited role in LDCs’ electricity generation mix, although its weight may expand somewhat as recently planned investments in new coal-based plants come online. As discussed in the next subsection, however, there is evidence of an acceleration of non-hydro renewable energy deployment in LDCs since 2014, and utility-scale plants currently under construction will increase their weight in the near future. At the 22nd Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC) (COP22), the Climate Vulnerable Forum (including 24 LDCs5) pledged to achieve 100 per cent renewable energy by 2050. Thus, half of the 47 LDCs — including island LDCs dependent on fossil-fuel generation as well as others with a larger share of renewable energy — consider a transition to a low-carbon power sector a strategic long-term objective. Other LDCs, such as Lao People’s Democratic Republic, Mozambique and Uganda, are also experimenting with the deployment of various renewable-based generation technologies.
