The geothermal exploration of Campanian volcanoes: Historical review and future development

Since Roman time, the heat produced by Neapolitan volcanoes was an appeal for people living in and outside the area, for the fruition of the famous thermal baths. This very large area, which spans from Campi Flegrei and Ischia calderas to Somma-Vesuvius volcano, is characterized by high temperature at shallow depth and intense heat flow, and is yet utilized for the bathing and spa treatment industry, while only in the middle of the 20th century a tentative of geothermal exploitation for energy production was performed. Pioneering researches of geothermal resource were carried out in Campanian region since 1930, until 1985, during which a large amount of geological data were collected. In this paper, we make for the first time a review of the history of geothermal explorations in the active Campanian volcanic area. By the analysis of a great amount of literature data and technical reports we reconstruct the chronology and the main information of the drillings performed since 1930 by the SAFEN Company and successively in the framework of the ENEL-AGIP Joint Venture for geothermal exploration. The available data are utilized to correlate the temperatures measured within the deeper wells with the possible sources of geothermal heat in the shallow crust, down to about 8-10 km of depth. Finally, we assess the geothermal potential of the hottest areas, Ischia Island and Campi Flegrei, which have shown the best data and favorable physical conditions for a reliable, and cost-effective, exploitation for thermal and electric purposes.     

Implementation of coal development programs and the future role of indonesia as a potential coal supplier in the southwest Pacific region

The 1973 oil crisis and the increased domestic oil consumption during the 1970s made Indonesia aware of the vulnerability of its petroleum-based economy. Since oil—a limited energy resource—had formed the main source of foreign exchange earnings for decades, a policy of diversification of energy away from oil was imperative in order to meet the increasing energy demand in the country, while saving the valuable commodity for export purposes. An ambitious program to develop other energy resources, in particular coal, started with the rehabilitation and expansion of the two state-owned coal-mines in Sumatra. The coal produced was expected to fuel the newly built coal-fired power plants and the expanding cement industry.Aware of the limited available funds, the Government of Indonesia invited foreign investors to participate in the development of the nation's coal potential, especially in Kalimantan. The exploration efforts of these contractors resulted in the identification of vast reserves of coal that, when fully developed, would have been sufficient to meet the expected domestic coal demand. However, because of the world-wide recession and the sharp drop in oil revenue, ambitious construction programs in the power sector and the cement industry had to be restrained and coal consumption projections dropped substantially.In view of the vast coal potential identified, which in general is amenable to inexpensive openpit mining, and the large number of contractors involved in the development projects, it is anticipated that production capacity toward the end of the 1980s will far exceed domestic demand. Since the other ASEAN member countries and the northern industrialized Asian countries will be potential net importers of coal and in view of Indonesia's favorable geographic location, there is reason to believe that excess Indonesian coal can be allocated to the aforementioned export markets.     

Geothermal resources in Iran: The sustainable future

Because of disadvantages of fossil fuels, renewable energy sources are getting importance for sustainable energy development and environmental protection. Among the renewable sources, Iran has geothermal energy potential. The Iranian government is considerable attention to the utilization of renewable energy, especially wind, solar and geothermal energies. Due to recent advancements in geothermal energy, many investors in the country have become interested in investing in this type of energy. Geothermal studies in Iran started in 1975 with a cooperative between the ministry of Energy of Iran and ENEL Company from Italy. Preliminary studies indicated potential for geothermal power generation in four areas in northern Iran (Khoy-Maku, Sabalan, Sahand and Damavand at Azarbaijan Gharbi, Ardebil, Azarbaijan Sharghi and Tehran provinces), respectively. Geothermal development in Iran has gained momentum in the last five years with increased exploration and industry growth in the country. Iran is developing a geothermal plant for power production. Iran government plans to build 2000 MW of renewable energy capacity over the next five years. Total projected use (geothermal capacity) has been estimated 100 MW at the end of 2010. Exploration drilling is currently in-progress for Meshkinshahr project in North-Western Iran. The Sabalan geothermal power plant is expected to produce 50 MW electric powers in 2011. The plants are planned by Iran Ministry of Energy and the Renewable Energy Organization of Iran (SUNA). This study presents a brief introduction to the resource, status and prospect of geothermal energy in Iran.     

The distinction between coking coal and steaming coal — implications for the assessment of energy resources

Contemporary energy policy has been characterized by many assessments of in situ national energy stocks. While such assessments often include estimates of black coal reserves, no attempt is usually made to classify these reserves on the basis of their suitability for transformation into coke. This paper shows, by reference to the economic relationship between fossil fuels in the pig iron manufacturing and bulk heat markets, that coking coal and steaming coal are poor economic substitutes at current prices. From this it is concluded that there is a potential for misguided energy policymaking so long as national in situ black coal stocks continue to be assessed without regard for their coking properties.     

The UK coal industry—recent past and future

Against a background of rising prices and unsure supplies of oil, coal is rapidly regaining its former position as a key fuel in the UK. In this article, Mr Bailey traces the history of the industry from its decline in the 1960s to the substantial assistance given in the Coal Industry Act of 1973, and discusses the 1974 miner's wage settlement in relation to the future importance of coal for both the UK and the EEC.     

北京的地热资源及其开发利用前景

一前言地热资源是指在当前技术经济和地质环境条件下,人类能够科学、合理地开发出来的埋藏于地表以下岩石或流体中的热能及其伴生的有用组分。地热能与太阳能、风能、生物能、海洋能等统称为可再生能源。地热能只有转化为水、汽、干热气体或岩浆等形式才能为人类利用,通常把地热流体相对富集、具有一定渗透性并含载热流体的岩层或岩体破碎带称为热储,热储是地质勘探寻找和开发地热资源的重要目标。地热资源按其在地下的赋存状态可
