    Thousands of kanji characters were in use in various writing systems, leading to great difficulties for those learning written Japanese. Additionally, several characters had identical meanings but were written differently from each other, further increasing complexity. After World War II, the Ministry of Education decided to minimize the number of kanji by choosing the most commonly used kanji, along with simplified kanji (see Shinjitai) commonly appearing in contemporary literature, to form the tōyō kanji. This was an integral part of the postwar reform of Japanese national writing. This was meant as a preparation for re-introducing their previous unsuccessful reform abolishing Chinese characters. Although the postwar timing meant no public debate was held on the future of the Japanese written language, the defenders of the original kanji system considered and accepted the tōyō kanji as a reasonable compromise. Since this compromise could not then be withdrawn in favour of more rad...

    In addition to a list of the standardized tōyō kanji, the reform published by the Ministry for Education in 1946 also contains a set of guidelines for their use. Regarding provenance and scope, the foreword of the document states that: 1. The table of tōyō kanji put forth therein, are the selection of kanji recommended for use by the general public, including legal and governmental documents, newspapers, and magazines. 2. The presented kanji are selected as an approximate set of those characters found to be of no insignificant utility in the lives of today's Japanese citizens. 3. Concerning proper nouns, there is a wide range of usage beyond what may be formulated as rules, and consequently they are treated as outside the scope of this standard. 4. The simplified character forms from modern custom are taken as the proper form, and their original forms are provided alongside them for reference. 5. A systemization of the character forms and their readings is still under consideration...

    Because the majority of character-based words are composed of two (or more) kanji, many words were left with one character included in the Tōyō kanji, and the other character missing. In this case, the recommendation was to write the included part in kanji and the excluded part in kana, e.g. ふ頭 for 埠頭 and 危ぐ for 危惧. These words were called mazegaki(交ぜ書き, "mixed characters").

    The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet. Most of the world's population live in areas with insolation levels of 150–300 watts/m2, or 3.5–7.0 kWh/m2per day. Solar radiation is absorbed by the Earth's land surface, oceans – which cover about 71% of the globe – and atmosphere. Warm air containing evaporated water from the oceans rises, causing atmospheric circulation or convection. When the air reaches a high altitude, where the temperature is low, water vapor condenses into clouds, which rain onto the Earth's surface, completing the water cycle. The latent heat of water condensation amplifies convection, producing atmospheric phenomena such as wind, cyclones and ant...

    Solar thermal technologies can be used for water heating, space heating, space cooling and process heat generation.

    Solar power is the conversion of sunlight into electricity, either directly using photovoltaics (PV), or indirectly using concentrated solar power (CSP). CSP systems use lenses or mirrors and tracking systems to focus a large area of sunlight into a small beam. PV converts light into electric current using the photoelectric effect. Solar power is anticipated to become the world's largest source of electricity by 2050, with solar photovoltaics and concentrated solar power contributing 16 and 11 percent to the global overall consumption, respectively.In 2016, after another year of rapid growth, solar generated 1.3% of global power. Commercial concentrated solar power plants were first developed in the 1980s. The 392 MW Ivanpah Solar Power Facility, in the Mojave Desert of California, is the largest solar power plant in the world. Other large concentrated solar power plants include the 150 MW Solnova Solar Power Station and the 100 MW Andasol solar power station, both in Spain. The 250...

    Sunlight has influenced building design since the beginning of architectural history. Advanced solar architecture and urban planning methods were first employed by the Greeks and Chinese, who oriented their buildings toward the south to provide light and warmth. The common features of passive solar architecture are orientation relative to the Sun, compact proportion (a low surface area to volume ratio), selective shading (overhangs) and thermal mass. When these features are tailored to the local climate and environment, they can produce well-lit spaces that stay in a comfortable temperature range. Socrates' Megaron House is a classic example of passive solar design. The most recent approaches to solar design use computer modeling tying together solar lighting, heating and ventilation systems in an integrated solar design package. Active solarequipment such as pumps, fans, and switchable windows can complement passive design and improve system performance. Urban heat islands (UHI) ar...

    Agriculture and horticulture seek to optimize the capture of solar energy to optimize the productivity of plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields. While sunlight is generally considered a plentiful resource, the exceptions highlight the importance of solar energy to agriculture. During the short growing seasons of the Little Ice Age, French and English farmers employed fruit walls to maximize the collection of solar energy. These walls acted as thermal masses and accelerated ripening by keeping plants warm. Early fruit walls were built perpendicular to the ground and facing south, but over time, sloping walls were developed to make better use of sunlight. In 1699, Nicolas Fatio de Duillier even suggested using a tracking mechanism which could pivot to follow the Sun. Applications of solar energy in agriculture aside from growing crops include pumping water, dr...

    Development of a solar-powered car has been an engineering goal since the 1980s. The World Solar Challenge is a biannual solar-powered car race, where teams from universities and enterprises compete over 3,021 kilometres (1,877 mi) across central Australia from Darwin to Adelaide. In 1987, when it was founded, the winner's average speed was 67 kilometres per hour (42 mph) and by 2007 the winner's average speed had improved to 90.87 kilometres per hour (56.46 mph).The North American Solar Challenge and the planned South African Solar Challengeare comparable competitions that reflect an international interest in the engineering and development of solar powered vehicles. Some vehicles use solar panels for auxiliary power, such as for air conditioning, to keep the interior cool, thus reducing fuel consumption. In 1975, the first practical solar boat was constructed in England. By 1995, passenger boats incorporating PV panels began appearing and are now used extensively. In 1996, Kenichi...

    Solar chemical processes use solar energy to drive chemical reactions. These processes offset energy that would otherwise come from a fossil fuel source and can also convert solar energy into storable and transportable fuels. Solar induced chemical reactions can be divided into thermochemical or photochemical. A variety of fuels can be produced by artificial photosynthesis. The multielectron catalytic chemistry involved in making carbon-based fuels (such as methanol) from reduction of carbon dioxide is challenging; a feasible alternative is hydrogen production from protons, though use of water as the source of electrons (as plants do) requires mastering the multielectron oxidation of two water molecules to molecular oxygen. Some have envisaged working solar fuel plants in coastal metropolitan areas by 2050 – the splitting of seawater providing hydrogen to be run through adjacent fuel-cell electric power plants and the pure water by-product going directly into the municipal water sys...

    Thermal mass systems can store solar energy in the form of heat at domestically useful temperatures for daily or interseasonal durations. Thermal storage systems generally use readily available materials with high specific heat capacities such as water, earth and stone. Well-designed systems can lower peak demand, shift time-of-use to off-peakhours and reduce overall heating and cooling requirements. Phase change materials such as paraffin wax and Glauber's salt are another thermal storage medium. These materials are inexpensive, readily available, and can deliver domestically useful temperatures (approximately 64 °C or 147 °F). The "Dover House" (in Dover, Massachusetts) was the first to use a Glauber's salt heating system, in 1948. Solar energy can also be stored at high temperatures using molten salts. Salts are an effective storage medium because they are low-cost, have a high specific heat capacity, and can deliver heat at temperatures compatible with conventional power systems...

    Beginning with the surge in coal use, which accompanied the Industrial Revolution, energy consumption has steadily transitioned from wood and biomass to fossil fuels. The early development of solar technologies starting in the 1860s was driven by an expectation that coal would soon become scarce. However, development of solar technologies stagnated in the early 20th century in the face of the increasing availability, economy, and utility of coal and petroleum. The 1973 oil embargo and 1979 energy crisis caused a reorganization of energy policies around the world. It brought renewed attention to developing solar technologies. Deployment strategies focused on incentive programs such as the Federal Photovoltaic Utilization Program in the US and the Sunshine Program in Japan. Other efforts included the formation of research facilities in the US (SERI, now NREL), Japan (NEDO), and Germany (Fraunhofer Institute for Solar Energy Systems ISE). Commercial solar water heaters began appearing...

    Solar energy is not available in all regions, due to geographic location or due to deployment and infrastructure. For instance, while the European Union has installed more than 130 GW of capacity in 2019, China had reached more than 200 GW and the US more than 100 GW. The Desertec Foundation has estimated that an area of ~300 x 300 miles in the Saharaarea would be sufficient to produce all the electricity the world used (based on 2005 levels). Summaries of solar energy use and production are available on these pages: Africa and Middle East: Israel, Morocco, Saudi Arabia, South Africa, Yemen Europe: Austria, Belgium, Bulgaria, Czech Republic, Denmark, France, Germany, Greece, Cyprus, Italy, Lithuania, Netherlands, Poland, Portugal, Romania, Spain, Switzerland, Turkey, Ukraine, United Kingdom Americas: Canada, United States, Brazil, Chile, Mexico Asia: Burma (Myanmar), China, India, Japan, Pakistan, Thailand Australia and New Zealand
