Reducing Power Consumption Volume語 本 日




Today, energy is indispensable for daily life and industry.
However, there are various energy-related problems!
1.This is a worrisome problem.

The average per capita consumption of electricity in the world today is 3260 kwh, but Japan's consumption is higher than that at 8010 kwh. This means that more electricity is required in Japan than in other countries. However, there is a worrisome problem.

 2. Japan's Energy Self-Sufficiency Rate

Japan is a member of the OECD, the Organization for Economic Cooperation and Development(OECD) which is an international organization whose members are mainly from developed countries in Europe. Among the 35 countries in the OECD, Norway has the highest energy self-sufficiency rate at 792.6%, while Japan's energy self-sufficiency rate is only 9.6%.(100% means that a country can provide its own electricity in its own country.)

3. Energy Imports

Japan imports oil and other resources from Iraq and Saudi Arabia due to the scarcity of domestic resources. The breakdown is as follows: Saudi Arabia 40%, United Arab Emirates 36%, Kuwait 13%, and Qatar dash 11%.

4. What energy has been relied on in the past compared to the present?

In 1973, oil was the main source of energy in Japan, but the oil crisis brought oil usage down to 40% in 2010. Elsewhere, nuclear power dropped from 10% in 2010 to 1% in 2017 after the Great East Japan Earthquake. The reason why nuclear power has not been utilized as much is because the Great East Japan Earthquake caused an accident at a nuclear power plant, and nuclear power plants were shut down.

5.What Are Renewable Energies?

Renewable energies include solar power, wind power, geothermal power, small and medium-sized hydropower, and biomass. They are characterized by the fact that they do not emit greenhouse gases, can be produced domestically, and contribute to energy security. In Japan, renewable energies account for 10% of electricity generated, and solar power generation is the most common type of renewable energy.

  6. Energy of the Future

Renewable energy is one current source of energy . In Japan, renewable energy is expected to account for 40% of all energy in 2030, with nuclear power at 20%, LNG (liquefied natural gas) at 20%, coal at about 20%, and oil at 2%.

7. Electricity Consumption at Home

Although the number of people living in each household differs, the electricity consumption of one person is roughly 6.1 kwh per day. 2 people living together is about 1.7 times that of one person, 3 people living together is about 2 times, 4 people living together is about 2.2 times, and 5 people living together is about 2.4 times that of one person.

8. Household Appliances that Consume the Most Electricity

Refrigerators are the largest consumer of electricity in the household at 14.2%, followed by lighting fixtures at 13.4%, other home appliances at 8.9%, air conditioners at 7.4%, electric water heaters at 5.4%, eco-cutes at 3.8%, and other appliances at 46.9%.
