'''Buddhism''' is usually considered a  [[religion]]. On most estimates it has in the region of 350,000,000 adherents, making it the 4th to 6th largest religion in the world, and one of the three major universal religions (as distinct from those largely confined to a single ethnic group). There are "significantly large communities" of Buddhists in 126 countries.<ref>''World Christian Encyclopedia'', Oxford University Press, 2nd ed, 2001, volume 1, page 3</ref> Half the world's population live in areas where Buddhism is or was at some time a major force.
==Footnotes==
 
It was founded by Gautama, known as the  [[Buddha]] (literally ''Awakened One''). He lived and taught in areas now in northeast India and [[Nepal]]. Historians now generally date his death somewhere in the region of 400 BC. There are several major [[Buddhism#See also|branches of Buddhism]], each with notable differences in teachings. Buddhists divide themselves into [[Mahayana]] and [[Theravada]], the former being further subdivided.
 
===Nomenclature===
 
The word "Buddhism" is of course an English one, first recorded in 1801. "Native" Buddhists use names in their own languages. The name is derived from "Buddha" ([[Sanskrit]] and [[Pali]]), which is a title rather than a name. Literally it means "awakened". It is often translated as "enlightened".
 
The usual practice of Western scholars is to use Sanskrit terms when writing of Buddhism generally. Sanskrit was the language used by Buddhism in its heartland in the Middle Ages, but is little used by any Buddhists now. Theravada uses Pali, a dialect from an earlier phase of Buddhist history, while Chinese and Tibetan are widely used by those countries deriving their Buddhism from them.

After decades of failure to slow the rising global consumption of coal, oil and gas,[1] many countries have proceeded as of 2024 to reconsider nuclear power in order to lower the demand for fossil fuels.[2] Wind and solar power alone, without large-scale storage for these intermittent sources, are unlikely to meet the world's needs for reliable energy.[3][4][5] See Figures 1 and 2 on the magnitude of the world energy challenge.

Nuclear power plants that use nuclear reactors to create electricity could provide the abundant, zero-carbon, dispatchable[6] energy needed for a low-carbon future, but not by simply building more of what we already have. New innovative designs for nuclear reactors are needed to avoid the problems of the past.

Issues Confronting the Nuclear Industry

New reactor designers have sought to address issues that have prevented the acceptance of nuclear power, including safety, waste management, weapons proliferation, and cost. This article will summarize the questions that have been raised and the criteria that have been established for evaluating these designs. Answers to these questions will be provided by the designers of these reactors in the articles on their designs. Further debate will be provided in the Discussion and the Debate Guide pages of those articles.

Footnotes

  1. Global Energy Growth by Our World In Data
  2. Countries, organizations, and public figures that have reconsidered their stance on nuclear power are listed on the External Links tab of this article.
  3. Pumped storage is currently the most economical way to store electricity, but it requires a large reservoir on a nearby hill or in an abandoned mine. Li-ion battery systems at $500 per KWh are not practical for utility-scale storage. See Energy Storage for a summary of other alternatives.
  4. Utilities that include wind and solar power in their grid must have non-intermittent generating capacity (typically fossil fuels) to handle maximum demand for several days. They can save on fuel, but the cost of the plant is the same with or without intermittent sources.
  5. Mark Jacobson believes that long-distance transmission lines can provide an alternative to costly storage. See the bibliography for more on this proposal and the critique by Christopher Clack.
  6. "Load following" is the term used by utilities, and is important when there is a lot of wind and solar on the grid. Some reactors are not able to do this.
