Energy consumption structure of Japanese professional baseball games was analyzed. Multiple linear regression analyses of electricity consumption in stadiums indicated that the length of games, air-conditioning load (calculated from the temperature), starting time of games (day or night) and humidity affected the electricity consumption in most stadiums, and also the number of spectators and atmospheric pressure affected in some stadiums. Total electricity consumption was decomposed to each factors based on the result of the analyses. Nippon Professional Baseball had started "Green Baseball Project" in 2008, in which each player himself and team tries to save electricity through speedy play and to shorten the game length. Total electricity consumption in 2008 was reduced by 2.58% compared to 2007 and energy consumption by gas was also reduced, although the reduction ratio in the game length was no more than 1.4%. Furthermore, the degree in contribution of game length to total consumption of electricity increased in 2008. This cannot be explained by the reduction of game length, and these results suggested that some factors other than the game length also affected to the reduction of energy consumption such as the increasing awareness of players, spectators and stadium officers about energy saving, considering restricted contribution of game length to total electricity consumption.

エネルギー作物栽培は、よりエネルギー利用に特化した品種の導入や栽培技術の改善により、そのエネルギー効率を改善し、環境負荷を低減させることが可能である。本研究ではテンサイ、バレイショ、カンショ、ソルガム、サトウキビの5種類のエネルギー作物について、品種改良や栽培技術上の改善がライフサイクルでのエネルギー効率や温室効果ガス排出量に与える影響を評価し、慣行栽培に比べどの程度エネルギー効率を改善でき、環境負荷を低減できるかを検討した。
