Denryoku mondai wa dou miru noga tadashiika
Denryoku mondai
Denryoku mondai souran
Denryoku mondai zadankai
Denryoku mondai ni tsuki
Denryoku mondai no shinsou
Denryoku mondai o yoron ni kiku
Denryoku tousei mondai hihan
Kakushin seisaku no ue kara mita denryoku mondai hihan
Denryoku minyuu kokuei mondai
Denryoku tousei mondai ni kansuru shiryou
Denryoku minyuu kaneian to denki ryoukin mondai
Denryoku mondai : minyuu kokuei an o nanzu
Nihon wa dokomade yukuka
Nihon wa dokomade yukuka
Denryoku kokka kanri mondai no konpon igi
Denryoku kokuei mondai to sono shisouteki konkyo
Tousei keizai to denryoku kokuei mondai ni tsuite
Denryoku kokuei mondai : zen sangyoukai ihen no daiippo
Shisoujou kara mita denryoku mondai no shinsou : ippan zaikai eno eikyou ikani
Denryoku kokka kanrian zaikai ni dou hibiku
Kokunai kaikaku mondai o gunbu wa dousuruka
Gakusei shisou mondai zatsuwa : karera wa doushite sakeishitaka
Keiji mondai ga okitaraba
