Generation of electricity using Biomass in Nova scotia, Canada Term Paper

Generation of electricity using Biomass in Nova scotia, Canada - Term Paper Example People are deeply at odds over the proposal, for many support this idea when some others question the viability and sustainability of this project. Evidences suggest that today many countries are successfully generating electricity from biomass to resolve their electricity crises. Referring to the shortcomings of other major electricity generation techniques and the available resources of Nova Scotia, it can be argued that electricity generation from biomass will be a potential proposal for the region. This paper will discuss why Nova Scotia must generate electricity from biomass to meet its power needs and to make electricity cost affordable to its people. 2. Discussion 2:1. Potentiality of generating electricity from biomass â€Å"Biomass is biological material derived from living, or recently living organisms† (Biomass Energy Centre). Biomass is a broader term that represents diverse fuels derived from agriculture and food wastes and timber. Sewage sludge and animal manure may also form biomass fuel whereas it is also derived from trees. Considering the regeneration capacity of trees, it seems that biomass fuels are renewable. In the context of rapidly deteriorating non-renewable energy resources, the biomass fuels have a vital role to play in the electricity generation. ... Currently, lumber or other wood wastes are burnt in most biomass power plants. According to Augustine and Bockenhauer, in direct combustion power plants, biomass fuel is burnt direct in boilers which in turn provide steam for steam-electric generators. Under the biomass gasification process, biomass is initially converted into methane which is capable of fuelling steam generators, fuel cells, and combustion turbines. The major benefit of biomass gasification over direct combustion is that â€Å"extracted gasses can be used in a variety of power plant configurations† (Power Scorecard). The major argument against biomass fuelled power plants is that they cause air emissions. Although this argument is valid and has many environmental reasons to justify, it is not sufficient to abandon the concept of biomass fuelled electricity. Air emissions can be reduced by carefully choosing fuel and technology. There is a common perception that electricity generated using renewable technologi es is more expensive than the electricity generated from fossil fuels. Although it may be true in the case of wind energy and solar energy, electricity generation using biomass is cost-effective. In addition, this technique is considered to be greenhouse neutral. This feature is really advantageous in the context of current global warming and climate change issues. According to the findings of US Energy Information Administration, biomass fuelled power plants assist the agriculture industry to solve waste disposal problems. In terms of availability, biomass is better than other renewable technologies such as solar energy. Since biomass is easy to convert into high energy portable fuel forms like gas or alcohol, electricity can be easily generated from biomass without the application of

WHICH METHOD (MRI OR DIAGNOSTIC MAMMOGRAPHY) IS MORE SENSITIVE AT DECTECTING BREAST CANCER IN WOMEN UNDER THE AGE OF 50 - RESEARCH PROPOSAL - Essay Example Medical experts impute the decline in breast cancer deaths to earlier detection and more efficient treatments. Breast cancer is dangerous because of its early latent character and long asymptomatic stage. Treatment can be much more effective if detected in the early stages. The benefits of early detection are capable of offsetting the anticipated risks and costs involved. This research project is therefore proposed to examine the relative sensitivity and cost effectiveness of two methods of detecting breast cancer. The methods examined are Magnetic Resonance Imaging and Digital Mammography. The study is confined to women under the age of fifty due to the particular issues faced by patients in this age group. Breast cancer is a common form of cancer, accounting for a high rate of mortality among women, next only to lung cancer (Taft & Taylor, 2001). The incidence of breast cancer is on the rise all over the world, posing a significant risk for women. One out of eight women in the developing world is estimated to develop breast cancer at some stage of their lives. Among the various factors identified as responsible for the incidence of breast cancer, genetics, environmental and lifestyle risk factors are considered significant ones (Nkondjock, & Ghadirian, 2005). Mortality caused by breast cancer is especially high among women between the ages of forty and forty-nine. Even apart from the mortality rates, the emotional and psychological impact of the condition is severe. Fear of the disease and the nature of treatment to be undertaken add to the negative impact (Breast Cancer Screening For Women Ages 40-49 – NIH Consensus Statement. Medscape General Medicine. 1999) Early, accurate detection leading to effective and less drastic treatment methods can significantly reduce the trauma associated with breast cancer, resulting in better prognosis and
