Electricity Sector In Japan
The electric power industry in Japan covers the generation, transmission, distribution, and sale of electric energy in Japan. Japan consumed approximately 918 terawatt-hours (TWh) of electricity in 2014. Before the 2011 Fukushima Daiichi nuclear disaster, about a quarter of electricity in the country was generated by nuclear power. In the following years, most nuclear power plants have been on hold, being replaced mostly by coal and natural gas. Solar power is a growing source of electricity, and Japan has the third largest solar installed capacity with about 50 GW as of 2017. Japan's electricity production is characterized by a diverse energy mix, including nuclear, fossil fuels, renewable energy, and hydroelectric power. Japan has the second largest pumped-hydro storage installed capacity in the world after China. The electrical grid in Japan is isolated, with no international connections, and consists of four wide area synchronous grids. Unusually, the Eastern and Western gr ...

Electricity Production In Japan
Electricity is the set of physical phenomena associated with the presence and motion of matter possessing an electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others. The presence of either a positive or negative electric charge produces an electric field. The motion of electric charges is an electric current and produces a magnetic field. In most applications, Coulomb's law determines the force acting on an electric charge. Electric potential is the Work (physics), work done to move an electric charge from one point to another within an electric field, typically measured in volts. Electricity plays a central role in many modern technologies, serving in electric power where electric current is used to energise equipment, and in electronics dealing w ...

EU15
The 1995 enlargement of the European Union saw Austria, Finland, and Sweden accede to the European Union (EU). This was the EU's fourth enlargement and came into effect on 1 January of that year. It is also known as the EFTA Enlargement round. All these states were previous members of the European Free Trade Association (EFTA) and had traditionally been less interested in joining the EU than other European countries. Norway had negotiated to join alongside the other three, but following the signing of the treaty, membership was turned down by the Norwegian electorate in the 1994 national referendum. Switzerland also applied for membership on 26 May 1992, but withdrew it after a negative referendum result on 6 December 1992 (and that was not changed after a second negative referendum result on 4 March 2001). Closer links The three states, plus Norway and Switzerland (which never joined due to their referendum results) began ...

Electricity Market
An electricity market is a system that enables the exchange of electrical energy, through an electrical grid. Historically, electricity has been primarily sold by companies that operate electric generators, and purchased by consumers or electricity retailers. The electric power industry began in the late 19th century in the United States and United Kingdom. Throughout the 20th century, and up to the present, there have been deep changes in the economic management of electricity. Changes have occurred across different regions and countries, for many reasons, ranging from technological advances (on supply and demand sides) to politics and ideology. Around the turn of the 21st century, several countries restructured their electric power industries, replacing the vertically integrated and tightly regulated "traditional" electricity market with market mechanisms for electricity generation, transmission, distribution, and retailing. The traditional and competitive market app ...

Nuclear Power In Japan
Nuclear power generated 5.55% of Japan's electricity in 2023. The country's nuclear power industry was heavily influenced by the Fukushima accident, caused by the 2011 Tōhoku earthquake and tsunami. Before 2011, Japan was generating up to 30% of its electrical power from nuclear reactors. After the Fukushima accident, all reactors were shut down temporarily. , of the 54 nuclear reactors present in Japan before 2011, there were 33 operable reactors but only 13 reactors in 6 power plants were actually operating. A total of 24 reactors are scheduled for decommissioning or are in the process of being decommissioned. Others are in the process of being reactivated, or are undergoing modifications aimed to improve resiliency against natural disasters; Japan's 2030 energy goals posit that at least 33 will be reactivated by a later date. The Fukushima accident hardened attitudes toward nuclear power. In June 2011, immediately after the accident, more than 80% of Japanese said they wer ...

Japan Times
''The Japan Times'' is Japan's largest and oldest English-language daily newspaper. It is published by , a subsidiary of News2u Holdings, Inc. It is headquartered in the in Kioicho, Chiyoda, Tokyo. History ''The Japan Times'' was launched by on 22 March 1897, with the goal of giving Japanese people an opportunity to read and discuss news and current events in English language, English to help Japan participate in the international community. In 1906, Zumoto was asked by Japanese Resident-General of Korea Itō Hirobumi to lead the English-language newspaper ''The Seoul Press''. Zumoto closely tied the operations of the two newspapers, with subscriptions of ''The Seoul Press'' being sold in Japan by ''The Japan Times'', and vice versa for Korea. Both papers wrote critically of Korean culture and civilization, and advocated for Korea under Japanese rule, Japan's colonial control over the peninsula in order to civilize the Koreans. The newspaper was independent of government ...

Renewable Energy In The European Union
Renewable energy progress in the European Union (EU) is driven by the European Commission's 2023 revision of the Renewable Energy Directive, which raised the EU's binding renewable energy target for 2030 to at least 42.5%, up from the previous target of 32%. Effective since November 20, 2023, across all EU countries, this directive aligns with broader climate objectives, including reducing greenhouse gas emissions by at least 55% by 2030 and achieving climate neutrality by 2050. Additionally, the Energy 2020 strategy exceeded its goals, with the EU achieving a 22.1% share of renewable energy in 2020, surpassing the 20% target. The largest renewable energy category for Europe in 2023 was solid, liquid, and gaseous biomass, which comprised half of all renewable energy consumption that year. In particular, wood is the leading source of renewable energy in Europe, far ahead of solar and wind. In 2023, renewables provided 26.2% of total EU energy consumption in heating and cooling, ma ...

Solar Energy
Solar energy is the radiant energy from the Sun's sunlight, light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture. It is an essential source of renewable energy, and its technologies are broadly characterized as either passive solar or active solar depending on how they capture and distribute solar energy or convert it into solar power. Active solar techniques include the use of photovoltaic systems, concentrated solar power, and solar water heating to harness the energy. Passive solar techniques include designing a building for better daylighting (architecture), daylighting, selecting materials with favorable thermal mass or light-dispersing properties, and organizing spaces that ventilation (architecture), naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technolo ...

Waterpower
Hydropower (from Ancient Greek -, "water"), also known as water power or water energy, is the use of falling or fast-running water to produce electricity or to power machines. This is achieved by converting the gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce carbon dioxide or other atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. International institutions such as the World Bank view hydropower as a low-carbon means for economic development. Si ...

Biomass
Biomass is a term used in several contexts: in the context of ecology it means living organisms, and in the context of bioenergy it means matter from recently living (but now dead) organisms. In the latter context, there are variations in how biomass is defined, e.g., only from plants, from plants and algae, from plants and animals. The vast majority of biomass used for bioenergy does come from plants and fecal matter. Bioenergy is a type of renewable energy that the bioenergy industry claims has the potential to assist with climate change mitigation. Uses in different contexts Ecology * Biomass (ecology), the mass of living biological organisms in a given area or ecosystem at a given time. This can be the biomass of particular species or the biomass of a particular community or habitat. Energy * Biomass (energy), biomass used for energy production or in other words: biological mass used as a renewable energy source (usually produced through agriculture, forestry or ...
