With respect to “energy mix” that determines the composition of the electric power sources as of 2030, the government has firmly established a policy that the ratio of renewable energy such as solar, wind, and hydroelectric power will exceed nuclear power. Renewable energy is estimated to be somewhere in mid-20s percentile whereas nuclear power will be between 20 and 25%; thereby, the government can show clearly its stance of attaching importance to renewable energy. The Ministry of Economy, Trade and Industry will make a proposal on the policy to an expert panel at the end of April.
The breakdown of electric power sources before the East Great Japan Earthquake was 60% for thermal power; 30% for nuclear power; and 10% for renewable energy. With the shutdown of nuclear power plants, the composition is currently 90% for thermal power and 10% for renewable energy. The government is currently deliberating on ways to raise the ratio of nuclear power and renewable energy while reducing greenhouse-gas emitting thermal power generation, which contributes to global warming as well as drives up the cost of imported fuel.
The government announced in the Basic Energy Plan decided in April 2014 to reduce dependence on nuclear power as much as possible. Therefore, in order to apply the brakes on global warming, the government judged that active introduction of renewable energy is inevitable. At the same, amid the expected start-up as early as this summer of Kyushu Electric Power’s Sendai Nuclear Power Plant (Kagoshima Prefecture), the government aims to lessen public opposition.
