[en] On behalf of ADEME, the DREAL and the Region of Brittany and produced by ENEA, consulting company in energy and sustainable development, this brochure presents main technologies for power and thermal energy generation in an effort to maintain objectivity (efficiency, intrinsic features of each technology and key figures as regards power and energy). If most of the technologies are operational or in development in Brittany, such as ocean energy, the scope has been extended to encompass all existing technologies in France in order to give useful references. The French Brittany is a peninsula, with regards to both its geographic situation and its energy context. The region has decided to investigate energy and climate issue through the Brittany Energy Conference and to commit for energy transition. Discussions which have taken place since 2010 at the regional level as well as the national debate on energy transition in 2013 have highlighted the need for educational tools for the main energy generation technologies. Thus, the purpose of this brochure is to share energy stakes with a broad audience
[en] Projections show over 250 steam-electric and hydroelectric units beginning operation within the next 20 years in the US. The coal-fired, nuclear, geothermal, and hydroelectric plants listed in this report will add about 137 GWe (gross) to US electric capacity. Seven new units have begun operation since the last report. Other notable changes include the licensing of several nuclear plants, the removal of 14 coal-fired units from the data base, and the addition of five hydroelectric units. The report describes all known projected plants and lists architect/engineering firms, construction companies, and boiler and turbine/generator manufacturers if they are known
[en] In the paper some advantages and defects of the nuclear and conventional electro-power stations are compared. The considerations are conduct over the charges of electric energy generation in the both kinds of power station, on the example of Opole electro-power station and nuclear power station in Bezanu.

[en] This paper gives a short overview about the types of power stations in Germany and Poland. The energy production in Germany in 2012 was 629,7 TWh. Every type of power plant poses a risk to humans and the environment but in a different way and to a different extent. A discrete mathematical method, named Hasse diagram technique is applied. The software package used is the PyHasse software. A first ranking approach is presented taking the 8 most used types of power plants in Germany into account and ranking those applying 5 different evaluation criteria, including 3 environmental health attributes. In this first approach not only nuclear power stations but also coal-driven power stations come worst in this ranking method. Renewable energies come best in our approach. Unfortunately their percentage of the overall energy production is still too low (about 22,1 % in Germany and 10,4 % in Poland). This underlines the necessity for urgently supporting the development of renewable energy power plants. Furthermore, we plan to extend our scoring approach to other European countries, starting with the neighboring country Poland.
[en] New UDI report combines historical construction costs for more than 1,000 coal, oil, gas, nuclear and geothermal units that have entered commercial operation since 1966 and projected power plant construction costs for about 400 utility-owned generating units scheduled to enter commercial operation during the next 20 years. Key design characteristics and equipment suppliers, A/E, constructor and original installed cost data. Direct construction costs without AFUDC are provided where known. Historical construction cost data are also provided for about 130 utility-owned hydroelectric, gas turbine, combined-cycle and diesel units (these data are generally for units entering service after 1980)
[en] This Practical information sheet explains how to generate electricity from low-carbon solutions. To do so, it is necessary to identify: - the local decarbonated energy sources; - the power generation processes for each local carbon-free source
[fr]Vous souhaitez produire de l'energie electrique a partir de solutions decarbonees. Il vous faudra pour cela identifier: - les sources d'energies decarbonees locales; - les procedes de production de l'energie electrique pour chaque source decarbonee locale
[en] This revised edition incorporates newer topics and modern instruments introduced in the subject area. It has improved and updated coverage on load duration curves and Indian energy scenario, in-depth coverage of hydroelectric, diesel engine and gas turbine power plants. It covers unique chapters on energy storage mechanism with new sections on supercritical boilers, ultra-supercritical and advanced ultra-supercritical technology, flue gas de-nitrification, desulphurization etc.
[en] The most common heat exchanger design problems are rating and sizing problems. In this paper the basic design methods for two-fluid direct-transfer heat exchangers are reviewed. A heat exchanger is a device in which heat is transferred from a hot fluid to a cold fluid. In its simplest form, the two fluids mix and leave at an intermediate temperature determined by the conservation of energy. This device is not truly a heat exchanger but rather a mixer. In most applications, the fluids do not mix but transfer heat through a separating wall that takes on a wide variety of geometries. Three categories are normally used to classify heat exchangers: recuperators, regenerators, and direct-contact apparatus
[en] The topics discussed include environmental impacts of the use of fossil fuels and renewable energy sources for electricity generation, and impacts of the use of nuclear energy accruing from the normal operation of nuclear power plants and from accidents, from uranium ore mining and processing, nuclear fuel fabrication and reprocessing, radioactive material transportation, and nuclear waste storage and disposal.
