''by [[User:Nick Gardner|Nick Gardner]]''
<small>
----The term '''[[Arab Spring]]''' (also known  as the "Arab Awakening") refers to the sequence of protest movements that started  in Tunisia in December 2010. The  protests there, and subsequently  in other Arab countries, were  intended to put an end to  government oppression, corruption and incompetence. They have led to the overthrow of existing regimes in Egypt and in Libya as well as in Tunisia, and to the initiation in those countries of transitional plans that include the election of representative assemblies and the adoption of new constitutions. Major protest movements in Syria and in Yemen have so far been frustrated by governmental violence, and protest movements elsewhere in the Arab world have achieved little more than promises of minor reforms.

===Background: the Arab condition===
</small>
The political structures of nearly all of the countries involved in the Arab uprisings have  been categorised as authoritarian (with Syria, Libya and Saudi Arabia ranking among the 15 least democratic countries), and the governments of five of them have been categorised as exceptionally corrupt (Morocco, Egypt, Algeria, Libya and Yemen appear among the upper half  in the ranking of Transparency International's Corruption Perception Index). Their populations are predominately ethnically Arab with small native Berber minorities. They include two mixed oil economies (Algeria and Libya); three oil economies (Bahrain, Oman and Saudi Arabia); six diversified economies (Egypt, Jordan, Lebanon, Morocco, Syria and Tunisia); and  one primary export economy (Yemen). The oil-producing countries of Oman, Bahrain, Saudi Arabia and Libya are among the world's more prosperous countries, but the prosperity of each of the others is below, or well below the world average in terms of GDP per head, with Syria ranking 153rd out of a total of 228. At least 19% of the Arab population lived below the poverty line at the end of the 1990s (according to an estimate based upon data from Egypt, Jordan, Morocco, Tunisia and Yemen.
 
===The development of national protest movements===
Protesters in Tunisia and in Egypt succeeded within a few months in ousting their governments, and  regime change was achieved in Libya after eight months of civil war. The governments of Morocco, Algeria, Jordan and Oman responded to more limited protests with  promises of political and constitutional reform. In Saudi Arabia the administration sought to avoid confrontation by a  programme of infrastructure investment, and its forces were used to suppress dissent in Bahrain. Political instability in Lebanon  inhibited  governmental response to demonstrations for constitutional change. In Yemen and in Syria, continuing protests were frustrated by  violent military opposition.
 
The processes of creating democratically-elected governments now dominate the situations in Tunisia and Libya, and in Egypt they are being accompanied by sporadic demonstrations against the behaviour of its transitional military government. The transitional process in Libya  may be hampered by  the need to disarm its local militias. The undeterred vigour of the protest movements in Syria and Yemen suggests a continuing prospect of democratic transition. Elswhere in the Arab Spring countries, the prospects  appear to be limited to partial relaxations of authoritarian governance.

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.
