How Things Work: Micro Hydroelectricity in Japan - Our World

The Momura micro hydropower is an early example of generating electricity by using irrigation water, which has most often been for growing rice. Growing rice is a water-intensive business. For most of Japan’s rice fields, water is brought in through human-made irrigation systems that source water from local lakes and rivers.Get price

2019 – Understanding the current energy situation in Japan

Japan’s Energy Self-Efficiency Ratio and Dependence on ImportsChanges in Electricity RatesGreenhouse Gas (GHG) EmissionsEnergy Policy Toward 2030Energy such as electricity, gas and petrol, being indispensable for human life, is supporting our society. Japan, as a country that lacks resources such as oil and LNG (liquefied natural gas), needs various measures to secure a stable supply of energy. The energy self-efficiency ratio of Japan in 2017 was 9.6%, which is a low level when compared with other OECD countries. It has been increasing since 2014 when it was 6.4%, the lowest ever. However, a low energy self-efficiency ratio results in dependence on other countries for resources. This makes a country susceptible to the effects of international situations, causing difficulties in securing energy in a stable manner. Japan, in particular, is largely dependent on fossil fuels such as oil, coal and LNG (liquefied natural gas). In the year preceding the Great East Japan Earthquake, Japan was dependent on fossil fuels for 81.2% of the total primary energy supply. Dependence rose to 87.4% in 2017 as a result of increased utilization...Get price

Micro combined heat and power - Wikipedia

Micro combined heat and power, micro-CHP, µCHP or mCHP is an extension of the idea of cogeneration to the single/multi family home or small office building in the range of up to 50 kW. Usual technologies for the production of heat and power in one common process are e.g. internal combustion engines, micro gas turbines, stirling engines or fuel cells. Local generation has the potential for a higher efficiency than traditional grid-level generators since it lacks the 8-10% energy losses fromGet price
