[en] This paper presents a review of bio-diesel development and economic potentials. The basics of biodiesel and its production technology are described. Attention is given to development potential, challenges and prospests of bio-diesel in Nigeria with ground facts on bio-diesel production feasibility in Nigeria highlighted.
[en] The fusion community has created 'mini-Suns on Earth' to obtain unlimited, cheap, safe and clean energy. As little as two liters of water and 250g of stones are enough to cover a European family’s demand for energy for an entire year. In addition, the clean and harmless fusion product is the helium that fills the children balloons. In the last decade, fusion experiments have produced much more energy than consumed. The objective is to achieve the maximum efficiency of the market and thus create a renewable energy landscape. The discovery of materials that can withstand the temperature of the Sun shifts the fusion challenge from heat handling to impurity removal. The first explanation of the operating mode of high energy production 50 years ago had more tan 1500 citations. Here I present the first theoretical explanation of the improved mode, which also removes impurities while absorbing fuel for free, which expects the same citations and impact. This research, funded by ‘La Caixa’ and ‘Rafael del Pino Foundation’ Fellowships (<3% acceptance rate), has won the MIT, the Spanish Nuclear Society, the European (EPS) and the American (APS) Physical Society awards. The 6 publications and one patent derived from it are guiding experimental efforts and bringing fusion codes to a new dimension.
[en] This article reviews all the players of the photovoltaic industry in France (silicon producers, electrical component manufacturers, solar system manufacturers, design offices, solar system wholesalers, installers, and solar farm operators). For each company the following is reported: name, activity sector, historical background, staff, turnover, achievement and projects. (A.C.)
[en] The photovoltaic sector is continuing on track, just as the extent of solar energy's electricity-generating potential is dawning on the public mind. The annual global installation figure was up more than twofold in 2010 (rising from just short of 7000 MWp in 2009). It leapt to over 16000 MWp, bringing worldwide installed photovoltaic capacity close to 38000 MWp. The photovoltaic power generated in the European Union at the end of 2010 reached 22.5 TWh which means an additional capacity of 13023 MWp during 2010. Concerning the cumulated installed capacity, Germany and Spain rank first and second in the European Union with respectively 17370 MWp and 3808 MWp
[en] Nigeria's economic development has been held back by the underdevelopment of the energy sector. Despite being one of the world's major exporters of petroleum, the country has been unable to produce enough electricity to meet domestic demand. The difficulty in harnessing fossil fuels in Nigeria for electricity generation and the connected environmental questions coupled with the acute shortages in electricity generation and supply experienced in the nation have become topics of growing national importance and international attention. Many other clean alternative sources of energy are available, but most of them are either relatively undeveloped technologically or are not yet fully utilized. In this study, nuclear reactor as a primary energy source for clean energy is suggested. An assessment of electricity generation from nuclear energy is presented. A complete Nuclear Power Programme is proposed for Nigeria. A preliminary economical and environmental impact study is performed on the proposed programme. The presented work could be used as a nucleus for a feasibility study for applying this programme in any part of Nigeria with suitable site characteristics.
[en] A decline was expected for small wind turbine business with the advent of bigger wind turbines but it is really not the case. In 2014 the growth rate was about 10 % with a cumulated power installed that year of 830 MW for small wind turbines. China (41% of the installed capacity), United-States (30%) and Great-Britain (15%) are the 3 main players. About 1 million wind turbines are operating in the world - it means 8.3% (∼ 70.000 units) more than a year before. (A.C.)
[en] Our knowledge of Finnish geology and natural resources has considerably increased during the last few decades. Geological Survey of Finland - GTK has mapped the bedrock and Quaternary deposits, as well as mineral resources in great detail using modern geological, geochemical and geophysical techniques, so that Finland today has one of the best geological databases in the world. We have recently compiled countrywide datasets of seamless bedrock information at the scale of 1:200,000, and completed low-altitude airborne geophysical (200 m line spacing and 40 m terrain clearance), regional geochemical (80 000 samples), and reflection seismic surveys at the crustal scale and at high resolution on the main orepotential formations. Isotopic age determinations have been performed at GTK since the 1960s, and we now have accurate ages for about thousand samples, which is a key to studying the complex evolution of the Finnish Precambrian. GTK currently plays a vital role in providing geological expertise to the government, the business sector and the wider community. Specific responsibilities include the promotion and implementation of sustainable approaches to the supply and management of minerals, energy and construction materials, and to ensure environmental compliance through monitoring, assessment and remediation programmes. GTK also contributes to a wide range of international geoscience, mapping, mineral resources and environmental monitoring projects, and is active in developing multidisciplinary research programmes with universities, government agencies and stakeholders across related sectors. This 125th Anniversary Publication aims at elucidating, through a number of short articles, the current focus of research and development at GTK. In reaching the milestone of 125 years, we can state that our anniversary slogan, 'forever young', is justified by the vitality and increasing societal impact of the organization and our research focusing on sustainable development of our society. GTK is currently the centre of geoinformation and applied geoscientific expertise in Finland, and we have very active international co-operation and project export worldwide
[en] 164 scenarios of energy policies have been studied and it is shown that it is possible to reach a contribution for renewable energies between a quarter and 3 quarters of the energy consumed in 2050. The potentialities of renewable energies is huge and almost limitless so mankind is not facing a problem or energy resources but rather a lack of adequate technologies to use them. Today the potentiality of solar energy is the highest of renewable energies. The amount of investment required in any scenario is below 1% of the world national growth product. In fact all depend on the political willingness to embrace such drastic energy changes. (A.C.)
[en] This paper is a reprint of NEA Director-General, William D. Magwood, IV speech at the NEA 60. Anniversary High-Level Session. The speech makes a brief overview of the nuclear science revolution of the 20. Century, and introduces the Nuclear Energy Agency, from its birth in February 1958, to the evolution of its missions through the years as a response to the needs of its members
