The issue of protecting the environment and preventing environmental pollution is one of the priorities of Iran’s economic and social development plans. The purpose of this paper is to analyze changes in the environmental effects of electricity generation, as electricity production patterns change, on production and welfare of households in Iran by using the social accounting matrix of 2011 ...
In this study, thermodynamic and economic analysis of a photovoltaic electricity generation system (PVEGS) with and without self-cleaning panels is reported. In the first part, thermodynamic analyses are used to characterize the performance of the system. In the second part, the economic comparison of photovoltaic electricity generation with and without self-cleaning panels is carried out for a...
tehran has a population of over 12 million and produces more than 7500 tons of waste every day. tehran’s municipal solid waste is processed and landfilled at kahrizak disposal center. due to inappropriate waste management, a lake with a leachate volume of 180,000m3 has been formed. to solve this problem a leachate treatment plant is currently under construction. a byproduct of leachate treatmen...
in most of the developing countries, particularly in asian countries, the initial step of electricity industry restructuring has begun by spot market design. in addition, electricity industry, all around the world, is approaching competitive markets. meanwhile there are many unanswered questions including deregulation mechanism. in this new framework, producers are considered as private compani...
producing biogas is the most common method of energy generation in municipal and industrial wastewater treatment plants in the world. methane production rate depends on degradation rate of organic pollutants in wastewater, temperature and treatment process. typical parameters for assessment of organic wastewater such as bod or cod indicate the potential to produce methane. there is no accurate ...
Electricity generation and greenhouse gas (GHG) reductions were researched by making comparisons between municipal solid waste (MSW) landfill and incineration systems with three different electricity generation efficiencies - 10%, 21%, and 24.7%. For MSW landfill systems, it is shown that the total electricity generation is 198,747 MWh, and the total GHG emission reduction is 1,386,081 tonne CO...
Medium-term modeling of electricity market has essential role in generation expansion planning. On the other hand, uncertainties strongly affect modeling and consequently, strategic analysis of generation firms in the medium term. Therefore, models considering these uncertainties are highly required. Among uncertain variables considered in the medium term generation planning, demand and hyd...
Growing demand for electricity and the reduction of fossil fuels have made it essential to consider alternative and renewable energy sources, such as solar and wind, to generate electricity. In this paper, by computing levelized output energy cost and levelized cost of electricity, the prices of electricity generated from the different combined cycle, wind, and photovoltaic power plants are com...
Electricity is an essential energy that can benefit our daily lives. There are many sources available for electricity generation, such as coal, natural gas and nuclear. Among these sources, coal has been widely used in thermal power plants that account for about 41% of the worldwide electricity supply. However, these thermal power plants are also found to be a big pollution source to our enviro...
The paper provides an overview of the generation of electricity in 10 countries in South East Europe during 1995-2004. Using the latest available statistics the potential of the nascent integration of the electricity markets in South East Europe is explored. We conduct a cross-country analysis of electricity production based on different types of fuel used. The region has a low level of gasific...
