36. Policy instruments fostering wind energy projects: a multi-perspective evaluation approach

Author

Enzensberger, N., Wietschel, M., and Rentz, O.

Subjects
Energy policy -- Technology application, Decision support systems -- Usage, Policy sciences -- Models, Alternative energy sources -- Laws, regulations and rules, Technology application, Government regulation, Decision support software, Business, Environmental issues, Petroleum, energy and mining industries
Abstract

A more integrated evaluation approach taking into account the different interests of all relevant stakeholder groups in the three fields: renewable energy business, policy making and conventional power business is proposed. A number of policy instruments have been developed and implemented all over Europe aiming at supporting renewable energy project development.

43. Integration of price-depending demand reactions in an optomising energy emission model for the development of CO2-mitigation strategies

Author

Wietschel, M., Fichtner, W., and Rentz, O.

Subjects
Linear programming -- Analysis, Energy economics -- Research, Business, Business, general, Business, international
Abstract

Incorporation of price-depending demand approach to energy emissions models was undertaken to formulate and assess carbon dioxide (CO2)-mitigation strategies. Such act allows the inclusion of price-related changes in customer behavior on the study of emission mitigation strategies. It was shown that incorporation of price-depending demand approach leads to emission reduction costs that are lower compared to costs produced by a model without consumer price reaction consideration.

44. Environmental integrated production and recycling management

Author

Spengler, Th., Puchert, H., Penkuhn, T., and Rentz, O.

Subjects
Operations research -- Case studies, Production planning -- Management, Waste minimization -- Planning, Recycling (Waste, etc.) -- Management, Linear programming -- Case studies, Business, Business, general, Business, international
Abstract

Two case studies demonstrating the application of mixed-integer linear programming to environmental integrated production and recycling planning problems in Germany are discussed. The first involves the recycling of waste from dismantled buildings in the Upper Rhine Valley region. The second involves the Strategic Recycling Management System based on multistage capacitated warehouse location problems for recycling the byproducts of iron and steel mills.

45. Environmental integrated production planning for the ammonia synthesis

Author

Penkuhn, T., Spengler, Th., Puchert, H., and Rentz, O.

Subjects
Operations research -- Case studies, Nonlinear programming -- Case studies, Production planning -- Environmental aspects, Chemical processes -- Models, Business, Business, general, Business, international
Abstract

An environmental integrated operative planning model (OPM) was developed for ICI Inc.'s AMV process of ammonia synthesis. The nonlinear optimization model, which was constructed using the ASPEN PLUS process simulator, takes into consideration emission taxes as well as the byproducts and residues while generating input-output relations using nonlinear thermodynamic formulas. Its results, which demonstrate higher accuracy over other linear programming models, indicated the feasibility of enhancing the operating margin of ammonia production using the AMV process.

46. Emission reduction strategies for Central and Eastern Europe

Author

Lueth, O, Jattke, A., Schoettle, H., Wietschel, M., and Rentz, O.

Subjects
Central Europe -- Environmental aspects, Eastern Europe -- Environmental aspects, Air quality management -- Models, Business, Environmental issues, Petroleum, energy and mining industries
Abstract

The energy flow optimization model environment (EFOM-ENV) energy-environment model was applied to the Central and Eastern European countries of Poland, Ukraine, Czech and Slovak Republics with the aim of reducing emissions and formulating efficient energy systems. Results reveal that a reduction in CO2 emissions can also lead to a decrease in SO2 levels. The ensuing costs of emissions reduction per DM, such as fuel switching or energy saving, are shown to be lesser than in Western European countries.
