日本が直面するエネルギー問題 ─CO₂削減目標とエネルギーミックスにおける課題─

抄録

There are two urgent issues for Japan at present; one is the suppression and reduction of CO₂ and the other is the high cost of installation of renewable energy systems. Japan has set a goal of "26% reduction in the CO₂ level compared to that in 2013 before 2030" to counter global warming and is consciously being watched by the world as it seeks to achieve the target. Though it is considered an ambitious target, some pinpoint that Japan could aim high without knowing target of the EU is partly based on benchmark year by past inefficient eastern part of Europe and CO₂ emission from Japan accounts for just ∼3% of the total CO₂ emissions all over the world. Shifting to renewable energy from fossil fuels is believed to be essential for CO₂ reduction; however, solar power centric installation has caused serious problems in terms of defrayment by low-income citizens and small businesses. A specific reform plan for Feed-in-Tariff (FIT) to reduce the burden on the public to the lowest possible level is proposed by restarting nuclear power plants that can pass security verifications.
