Electricity expense has a large part in household budget.
But at the same time, home appliances are necessary to earn an ordinary life.

The point
Why do we try to save electricity in daily life? ・Energy conversion sector (power plant etc.) 39% ・Energy conversion sector (power plant etc.) 6%
Reference from the Japan Center for Climate Change Actions
・Nuclear power 0.5％
Reference from Agency for Natural Resources and Energy
We found about 50% respondents have negative images such as "I do not want to do it because it is troublesome" from questionnaire.
Reason for saving electricity can be thought for “The Earth” or “Future Generation”.
We thought about the reason why we do so from various view.
Carbon dioxide emissions
Percentage of carbon dioxide emissions by sector in Japan - Direct emissions of each sectors -
・Industry sector (factory etc.) 28%
・Transportation sector (car etc.) 17%
・Business or Others (Commercial, service, office etc.) 5%
・Household sector 4%
・Industrial process (limestone consumption etc.) 4%
・Waste (incineration of waste plastic, waste oil) 2%
・Agriculture and Others 0.3%
Carbon dioxide emissions by sector in Japan - indirect emissions of each sectors -
・Industry sector (factory etc.) 34%
・Transportation sector (car etc.) 17%
・Business or Others (Commercial, service, office etc.) 22%
・Household sector 15%
・Industrial process (limestone consumption etc.) 4%
・Waste (incineration of waste plastic, waste oil) 2%
・Agriculture and Others 0.3%
These chart were made by us.
“Direct Emission” shows the volume of CO2 emission in generating heat or electricity by those power producers.
“Indirect Emission” shows the volume of CO2 emission generated by the consumers of heat or electricity.
The gap between Direct from Indirect emission tells that CO2 emission from household covers 11% in 2015.
Large CO2 emission may change environment and it impacts to daily human activities.
The effect from saving electricity in household to total CO2 emission control is limited, however we believe it is important to always have a mind for saving energy and resources even the contribution is limited.
Energy self-sufficiency rate
Japan's Primary Energy Domestic Supply Structure and Self-Sufficiency Rate
・Geothermal energy and New energy 3.2％
・Hydraulic power 1.5％
・Coal 26.5％
・Natural gas 23.3％
・Petroleum 44.9％
・Energy self-sufficiency rate(%) = National production volume / Primary energy x 100
= 6.0%
This chart was made by us.
In Japan, primary energy is water, geothermal heat, nuclear power, natural gas and new energy.
Portion is small so that energy self-sufficiency ratio is only 6%.
Energy depletion
Number of years until resource exhaustion
Reference from Kansai Electric Power Company
This chart was made by us.
We do not have enough natural energy resources.
It is our duty to reduce unnecessary energy consumption.
Questionnaire
We found that many people are saving energy for household budget from questionnaire.
What is the purpose you want to conserve electricity at home? (Essential)
Questioned by Google Form.quantity of responses:88
60% of respondents answered "Purpose of electricity saving is reducing electricity bill."
In addition, 91% of people answered "Purpose is included reducing electricity bill ."
Image of power saving
What kind of image do you have for power saving? (Free will ・ Multiple answers possible)
Questioned by Google Form.quantity of responses:88
Based on the results of the questionnaire, we will introduce the image that we should have for power saving.
Contents
Although, forced to save more electricity below minimum level may impact health.
So, we decided to put a theme to saving electricity in easy way with keeping comfort life.
The point is to save unnecessary electricity.
We verify “How to save electricity in house with effective and efficient way”, by 2 points; “Use electricity with ZERO WASTE” and “Save electricity cost”
