Should energy data be consolidated in Tuvalu?
One of the study’s recommendations is the consolidation of all energy data, to build an energy balance and to include it in the annual economy report. Since Tuvalu’s electricity generation efficiency is low, around 35%, the significance of the electricity sector is higher in the primary energy balance than in final end-use consumption.
What is the balance of supply in Tuvalu?
The balance of supply is oil (Fig. 2). Tuvalu is close to being a totally oil dependent economy. In 2004 the total energy consumption was 4.6 ktoe 4, oil accounting for 3.8 ktoe (82%) and biomass for 0.8 ktoe (almost 18% of the total primary energy consumption).
How can Tuvalu protect its energy supply?
Protect Tuvalu’s energy supply from the whims of the international market. Using specific bioenergy technologies such as biogas digestion can help reduce pollution, run-off and contamination from organic waste, including human and animal sewage, therefore preventing land, sea, and groundwater contamination.
How much energy is wasted in Tuvalu?
Only 3,232 toe (71%) of primary energy supply reached an end-use category. 1,341 toe (29% of primary energy supply) was wasted, mainly due to low electricity generation efficiency. Tuvalu’s electricity consumption is increasing rapidly at a 3.8% yearly average rate over the last ten years. It reached 4,121 MWh in 2004.
What is Tuvalu's energy policy framework?
A PIEPSAP (Pacific Islands Energy Policy and Strategic Action Plan) National Energy Policy Framework has been developed for Tuvalu which emphasises renewable energy technologies (RET’s) for sustainable development. Once the GoT has accepted this framework, it must be put into practice.
What should the outputs and outputs of the Tuvalu energy sector development project be?
Outcomes and outputs (including, but not limited to, technical or policy recommendations, concept design, detailed design, equipment specification) should be consistent with the safeguard policies of the World Bank and the Environmental and Social Management Framework of the Tuvalu Energy Sector Development Project.
