What are Japan's new targets for renewable energy and how do they compare to previous levels?

Japan's new environmental plans set ambitious targets for renewable energy sources like solar and wind to account for 40-50% of electricity generation by 2040. This represents a significant increase from last year's level of 23% and exceeds the previous 2030 target of 38%. This substantial commitment to renewable energy is part of Japan's broader climate strategy to reduce greenhouse gas emissions and decrease dependence on imported fossil fuels, marking a decisive shift in the country's energy policy.
