The University of Tokyo and the Center for Low-Carbon Social Strategy have proposed a framework for "paying electricity bills as it is" from FY2014 in response to the fact that preparation for initial costs has become a hurdle to replace with energy-saving refrigerators at home, and it has become widespread. We are working. "Pay the electricity bill as it is" means that when a household installs energy-saving equipment such as a refrigerator, the financial institution will reimburse the necessary initial cost, and the amount equivalent to the electricity bill saved by introducing the energy-saving equipment will be the actual monthly electricity. A framework for repaying the equipment fee by paying it together with the fee.

　Since April 2015, Shizuoka Gas Co., Ltd. has also participated and measured the power consumption of refrigerators with the cooperation of 4 ordinary households, mainly in Mishima City, Shizuoka Prefecture.Based on the analysis results of this data, we propose "pay the electricity bill as it is" to 20 households.Two of them have replaced their refrigerators.

　At homes that actually replaced the refrigerator, we confirmed an energy saving effect of 60% or more (power saving effect of 1,500 yen / month or more in terms of electricity bill).If you set the monthly electricity bill you saved as the monthly repayment amount for the new refrigerator, you can repay the price in about 7 years, and after the repayment, the electricity bill for the refrigerator will be 400 yen or less every month.

　The University of Tokyo and others are aiming to spread "pay electricity bills as they are" nationwide, and in the future, by applying this framework to a wide range of equipment such as home appliances and lighting other than refrigerators, energy saving at home will be greatly improved. I hope it will be promoted.
