"Based on the Strategic Energy Plan, the Long-term Energy Supply and Demand Outlook presents the ideal structure of energy supply and demand that can be realized if appropriate measures are taken based on the fundamental direction of energy policies by envisioning policy objectives to be achieved on safety, energy security, economic efficiency, and environment, which are the basic ideas of the policies.
"Based on the policies stipulated in the Strategic Energy Plan, which the Cabinet approved in April 2014, METI established the Long-term Energy Supply and Demand Subcommittee under the Strategic Policy Committee of the Advisory Committee for Natural Resources and Energy in order to consider a future vision of a realistic, yet well-balanced energy supply and demand structure. So far, a total of 11 meetings on these matters have been held.
"METI has approved the Long-term Energy Supply and Demand Outlook based on the report compiled by the subcommittee."
The energy and demand outlook for 2030 serves as de facto energy efficiency and renewable energy targets. For renewable energy, it is described that Japan will aim to increase the share of renewables in total electricity generation to 22-24% by 2030. For energy efficiency, it is described that Japan will aim to reduce its final energy use by about 10%, from 361 million kl crude oil equivalent (coe) in 2010 to 326 million kl coe in 2030.
Original title: ????????????. For the primary energy supply, the envision structure for FY2030 is as follows: renewables 13-14%,Nuclear power: 10-11%, Natural gas: 18%, Coal: 25%, LPG: 3%, Oil 30%. For the power source mix, the structure is for FY2030 is as follows: Renewables: 22-24%, Nuclear power 20-22%, LNG: 27%, Coal: 26%, Oil 3%. Renewables are divided into: Geothermal: 1-1.1%; Biomass: 3.7-4.6%, Wind: 1.7%; Solar: 7%; Hydro: 8.8-9.2%. With a projection of economic growth at 1.7%/year, energy efficiency and conservation measures are also expected to allow a 196.1 bn kWh reduction (reduction of 17%).
Japan's INDC is developed based on this Long-Term Energy Supply and Demand Outlook.
