Electricity generation from renewable energy Japan FY 2022, by energy source

In the fiscal year 2022, the electricity produced from solar power in Japan stood at approximately 93 terawatt hours. To reduce greenhouse gas emissions and be less dependent on fossil fuel imports, the Japanese government is currently working on expanding electricity production from renewable energy sources.  Renewable energy in Japan  The share of renewable energy in electricity generation increased to around 20 percent in recent years. Until 2020, hydropower represented the largest renewable energy source in Japan. But since the conventional hydropower potential is considered to be almost fully developed, a further increase in capacity is hardly possible. The country currently makes investments in solar power a priority.The mountainous country has a lack of space for renewable power facilities on land. Therefore, it has recently made investments in floating solar panels and offshore wind farms with floating turbines. Wind energy currently only produces a small amount of energy supply, but the electricity production from offshore wind energy increased significantly in recent years.  Current climate policy To realize its climate goals as a member of the Paris Agreement, the Japanese government plans to reduce its greenhouse emissions by 46 percent until 2030, compared to the level of 2013. Furthermore, the Japanese prime minister announced the goal for the country to become entirely carbon neutral by 2050, with a renewable energy share of around 50 percent. Even though most Japanese people agreed that renewable energy generation should be increased to reduce greenhouse gas emissions, the expansion of nuclear energy as a source of low-carbon energy will also be essential to meet this goal.

在2022财政年度，日本通过太阳能产生的电力约为930亿千瓦时。为了降低温室气体排放并减少对化石燃料进口的依赖，日本政府目前正在致力于扩大可再生能源的电力生产。近年来，日本电力生产中可再生能源的占比已上升至约20%。截至2020年，水力发电曾是日本最大的可再生能源来源。然而，鉴于传统水力发电潜力几乎已完全开发，进一步增加产能的可能性微乎其微。目前，日本将投资太阳能作为优先事项。这个多山之国在陆地上缺乏可再生能源设施的空间，因此，近期已开始投资浮式太阳能板和配备浮式涡轮机的海上风力农场。风能目前仅产生少量的能源供应，但近年来，来自海上风能的电力生产显著增加。为实现作为《巴黎协定》成员国的气候目标，日本政府计划将温室气体排放量到2030年相比2013年水平减少46%。此外，日本首相宣布了到2050年使国家实现完全碳中和的目标，届时可再生能源占比将达到约50%。尽管大多数日本民众赞同应增加可再生能源发电以降低温室气体排放，但作为低碳能源来源的核能的扩展也将是实现这一目标的关键。
