Electricity supplies an increasing share of the world’s total energy demand and that contribution is set to increase. At the same time, there is increasing socio-political will to mitigate impacts of climate change as well as to improve energy security. This, in combination with the desire to...

The effective and rational energy generation and supply is one of the main presumptions of sustainable development. Combined heat and power production, or co-generation, has clear environmental advantages by increasing energy efficiency and decreasing carbon emissions. However, higher investment...

To mitigate greenhouse gas emissions, coal-fired electricity infrastructure needs to be replaced by low-carbon electricity generation options. Here we examine a range of possible alternative scenarios for sustainable electricity generation in South Korea, considering both physical and economic...

The paper brings new evidence on the impact of separate mechanical ventilation system on the annual energy and exergy performance of several design alternatives of residential heating systems, when they are designed for a house in Montreal. Mathematical models of residential heating, ventilation...

A preliminary feasibility study of the implementation of various absorption heat pump configurations in a Kraft pulping process has been performed. Three different cases were considered: (i) integration of a double lift heat transformer into the heat recovery circuit of the wood chips digesters...

To better understand how city-level greenhouse gas (GHG) emissions have evolved, we performed a multi-sectoral decomposition analysis to disentangle the GHG emissions in Tianjin from 2001 to 2009. Five sectors were considered, including the agricultural, industrial, transportation, commercial...

Many of the modern practices in waste management at the same time represent means of reduction of greenhouse gas (GHG) emissions. The main focus in this paper is given to the measures for recovering energy from municipal solid waste (MSW): Utilization of landfill gas for electricity production,...

In recent years, besides the energy issues, the GHG (greenhouse gas) emission, which is the most important cause of global warming, has received high attention. In order to have sustainable development, it is necessary to manage energy usage and GHG emissions in all production processes. This...

Although it is not at once evident, water supply and sanitation services provided by urban water and wastewater utilities consume a considerable amount of energy. Energy is an operational sine qua non in water treatment and distribution, wastewater collection, and treatment prior to disposal....

The impact on CO2 emissions of integrating new technologies (a biomass-to-Fischer–Tropsch fuel plant and a post-combustion CO2 capture plant) with a complex refinery has previously been investigated separately by the authors. In the present study these designs are integrated with a refinery...
