Which energy source is the best?
Most Efficient Energy Sources
Although there are many types of energy, the most efficient forms are renewable: hydro-thermal, tidal, wind, and solar. Solar energy has been proven to be the most efficient and effective among renewable energy sources for home and commercial use.
Where does the US get its electricity?
According to the U.S. Energy Information Administration, most of the nation’s electricity was generated by natural gas, coal, and nuclear energy in 2019. Electricity is also produced from renewable sources such as hydropower, biomass, wind, geothermal, and solar power.

Nuclear power plants
As of May 2019, there are 39 operable reactors in Japan. Of these, 9 reactors in 5 power plants are currently operating. Additionally, 5 reactors have been approved for restart and further 12 have restart applications under review.
Why is Japan energy poor?
Resource-poor Japan is dependent on imports for 94% of its primary energy supply. Japan’s energy supply structure is extremely vulnerable. … Despite these improvements, oil still accounts for about 40% of Japan’s primary energy supply, and more than 80% of imported oil comes from the politically unstable Middle East.
Does Japan have coal?
Japanese coal is found in the extreme ends of the country, in Hokkaidō and Kyūshū, which have, respectively, 45 and 40 percent of the country’s coal deposits. Kyūshū’s coal is generally of poor quality and hard to extract, but the proximity of the Kyūshū mines to ports facilitates transportation.

The Japanese intended the attack as a preventive action to keep the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States.
Is Japan rich with natural resources?
With few exceptions, Japan’s mineral reserves are small, and the quality of those mined is often poor. Coal, iron ore, zinc, lead, copper, sulfur, gold, and silver are among the most abundant minerals (in relative terms), with lesser quantities of tungsten, chromite, and manganese.
Why does Japan use 50HZ and 60HZ?
Initially it was an accident of history that evolved into a large installed base of 50 and 60 Hz power systems that are now too costly to change. In 1895, Germany’s AEG sold a 50 Hz generator to the power company in Tokyo, setting the Eastern half of Japan on the course towards a 50 Hz system.
