Energy markets are commodity markets that deal specifically with the trade and supply of energy. Energy market may refer to an electricity market, but can also refer to other sources of energy. Typically energy development is the result of a government creating an energy policy that encourages the development of an energy industry in a competitive manner. Until the 1970s when energy markets underwent dramatic changes, they were characterised by monopoly-based organisational structures. Most of the world's petroleum reserves were controlled by the Seven Sisters. Circumstances changed considerably in 1973 as the influence of OPEC grew and the repercussions of the 1973 oil crisis affected global energy markets. ==Liberalization and regulation== Energy markets have been liberalized in some countries; they are regulated by national and international authorities (including liberalized markets) to protect consumer rights and avoid oligopolies. Regulators includes the Australian Energy Market Commission in Australia, the Energy Market Authority in Singapore, the Energy Community in Europe, replacing the South-East Europe Regional Energy Market and the Nordic energy market for Nordic countries. Members of the European Union are required to liberalize their energy markets. Regulators seek to discourage volatility of prices, reform markets if needed, and search for evidence of anti-competitive behavior such as the formation of a monopoly. Due to the increase in oil price since 2003 and the increase of speculation, energy markets are being reviewed and by 2008, several conferences were organized to address the energy market sentiments of petroleum importing nations. In Russia, the markets are being reformed by the introduction of harmonized and all-Russian consumer prices. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「energy market」の詳細全文を読む スポンサード リンク
