Importance of Renewable Energy in Japan
Renewable Energy :
� Contributes to solving global warning
� Reduces import dependency through energy diversification (energy security)
� Contributes to creating new industries and jobs
However, the introduction of renewable energy systems always involves issues such as output
instability, high costs, and site constraints.
