Abstract: Energy demand in an entire community including multiple demanders is properly predicted and energy consumption thereof is properly controlled. Every day, some demanders are selected from the community and a request to adjust energy consumption for the following day is sent to the selected demanders. To decide a content of the request, energy demand for the following day is predicted. In this case, demanders which did not receive a request on past days are specified, and demand in the community for the following day is predicted based on the actual energy consumption by those demanders on the past days.

Abstract: A power demand regulating apparatus is provided which can efficiently achieve the purpose of peak shift in a power system and which can reduce the total incentive which an operator of a demand regulation server distributes to consumers having cooperated with a request for regulating an amount of energy to be used. A demand regulation server (0101) is provided with a cooperation level determining function (0111) of calculating a cooperation level which is obtained by quantifying the height of a cooperation sense of a consumer with a request for regulating an amount of energy to be used. The operator of the demand regulation server observes consumers or consumer appliances responding to the request for regulating an amount of energy to be used on the basis of the magnitude of the cooperation level and transmits the request to only the consumers or the consumer appliances.

Abstract: In a work vehicle, a cutoff-pressure-setting part sets cutoff pressure at a predetermined first pressure value when vehicle speed is greater than a predetermined first speed threshold, and at a second pressure value greater than the first pressure value when vehicle speed is equal to or less than a second speed threshold less than the first speed threshold.
