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.
