in such cases the international community should ideally provide the finance technology transfer and technical support needed for pursuing further decarbonization of ldc power sectors similarly environmental sustainability considerations call for an adequate assessment of the options for the safe disposal or recycling of generation apparatus containing potentially hazardous materials notably solar panels or in the case of largescale hydroelectricity projects of their potential social and environmental impact on riverbased ecosystems and related communities while the costs of storage technologies have declined rapidly over the last few years and may make battery storage a feasible option in due course this is not yet the case in all ldcs at least not at minigrid or utility scale
