Rainwater Harvesting: A Strategy For Reducing The Use Of Municipal Water
No full textCanadians, like most developed nations, enjoy unlimited access to high quality potable water pumped directly to their homes at a relatively low price. Although this may seem to be an ideal situation, the reality is that it is an unsustainable one, as the costs of operating the system are much greater than the user fees recovered, and fresh water supplies which were once thought to be abundant, are quickly becoming scarce. As a result there is a growing realization that there needs to be a change in the fundamental way in which water management is approached, that the supply side solution of simply expanding the centralized water distribution system is not the right path to take, and alternatives solutions, known as a ‘soft-path’ approaches are gaining in popularity. One such alternative is rainwater harvesting (RWH). The collection and storage of rainwater for human use, has been used throughout history for agricultural purposes, yet it has received little attention in modern society, mostly because the centralized water distribution system is so convenient and, a public work, inexpensive. However, increasing social trends of environmental consciousness and protection have led to the growing realization that freshwater is not an infinite resource, and that current rates of consumption and distribution methods are unsustainable. RWH is way of responding to this problem by reducing demand on the municipal infrastructure through the onsite collection and use of rainwater for normal domestic purposes. Only a small portion of the municipal water supply is drank, yet all of it is treated to the very high potable water standards at considerable expense. The vast majority of it is used for purposes which do not require potable water, such as flushing toilets or watering lawns, making the treatment process quite inefficient. This report will study the feasibility of Calgarians using rainwater to replace the non-potable uses of water in the home, and by doing so, how it could result in savings for the City through reduced demand on water infrastructure, while also benefiting the environment through reducing the amount of water withdrawn from the rivers while reducing the GHG emissions emitted by generating the electricity needed to power the system

No full textThis paper highlights one of the main challenges faced by modern Kuwait. Drinkable water is a major problem in Kuwait due to which the government had opted out for desalination plants. The paper explored the Ocean Thermal Energy Conversion (OTEC) as an alternate to desalination plants for Kuwait as the desalination plants are causing economic, social and environmental concerns as well as they are not sustainable in long term. The analysis explored the impact of OTEC on environment, economy, society and the technical feasibility in terms of providing desalinated water and electricity as a sustainable source

Oil Sands And Water
No full textThe oil sands of Northern Alberta contain extensive reservoirs of bitumen. This resource is very important for enhancement of domestic and international energy supplies as well for positive impacts to Canada’s economy. However, development of the oil sands is very controversial because of many issues, both social and environmental. In order to operate the oil sands industry in Northern Alberta must comply with government regulatory standards which are in place to address environmental impacts and public concern. Nevertheless, the pace of development and stringency of regulations may not be sufficient to consider long term and cumulative impacts to both available water quantity and quality. Technologies such as centrifuges, coagulants, in situ combustion, and steam/solvent in situ recovery, are in development which will reduce quantity of water use and impacts to water quality from oil sands development. It is the role and responsibility of government to ensure regulations are in place which allow this resource to be developed in a manner which ensures long term sustainability
Environmental Dispatch Of Electrical Power Generation With Air Quality Constraints Case Study : Ecuadorian Electricity Market
No full textThis investigation examines the Economic dispatch of electric power generation and its impacts on the environment and the Ecuadorian society.
Air emissions constraint during the production of electricity from thermal power plants are included within the scheme of dispatching electric power supply. This new approach considering economical, environmental and technical concerns is known as Environmental dispatch of electric power generation.
The implementation of the Environmental dispatch principle is applied to the Ecuadorian electric power sector.
The influence of meteorology and topography and diffusion on pollutants are analysed as well. Furthermore, this study focuses on for prevention and/or reduction techniques for nitrogen and Sulphur oxides, NOx and Sox, during the electricity generation from fossil fuels power plants
Evaluation Of The University Of Calgary Cogeneration Plant
No full textWith greenhouse gas (GHG) intensity of electrical power in Alberta being among the highest in Canada, facilities are adopting cogeneration technology to achieve reductions in GHG emissions while also benefiting from decreased energy costs. In 2011 the University of Calgary (U of C) completed construction of a $48 million cogeneration plant to work in conjunction with the campus district energy system with expectations of cutting emissions and reducing energy costs. The objective of this evaluation is to provide a high level review of the operation of: cogeneration technology, the U of C cogeneration plant, and energy consumption on the U of C Campus. Data reviewed and analyzed is from a sample operating year from November 2012 to October 2013. This evaluation will identify potential opportunities for system optimization that offer economic or environmental benefits as well as provide a detailed understanding of performance achievements and shortfalls
Investigation Of The Energy, Environmental, And Economic Aspects Of Waste To Energy Technology As An Alternative Solution To Divert Waste From Landfills In The City Of Calgary
No full textThis research project investigates whether waste to energy methods offer a better solution to the current landfill system in the city of Calgary considering the environmental, economic and energy aspects. Municipal solid waste is a by-product of a high consumption society. For some nations, waste became a renewable source of energy instead of a problem. European countries are using waste-to-energy as an effective waste treatment method that also generates energy. Sweden has been a worldwide pioneer and leader on converting waste into energy due to the environmental, economic, and energy aspects of municipal solid waste management. Conversely, Calgary is still using landfills as its primary waste treatment method. The city has one of the highest waste per capita volumes in Canada, which makes it one of the top waste producers globally
