High costs, unreliable resources for long term use and extensive negative impact on our environment are such problems associated with traditional sources of energy and fossil fuels which make us move toward implementation of renewable sources of energy. Fossil fuel pollution and reserve depletion in oil producing countries caused by increasing demands, make wind energy an attractive source of e...
A complete understanding of the limits, barriers, and equipment available for the use of national energy resources is essential. This will increase the use of existing regional energy potential and pave the way for sustainable development. In this study, the Green Cottage power management system from a renewable energy source was designed and evaluated using a decision-making algorithm. Thirtee...
The world's increasingly voracious appetite for fossil fuels is driven by fast-growing populations and ever-rising aspirations for the lifestyles and standard of living exemplified in the developed world. Forecasts for higher electricity consumption, more comfortable living environments (via heating or cooling) and greater demand for transport fuels are well known. Similar growth in demand is p...
© The Ecological Society of America www.frontiersinecology.org T energy demands of modern societies are steadily increasing. Today, much of this demand is satisfied by fossil fuels, such as gas, oil, and coal, energy resources that are not renewable, and which will eventually be exhausted. The first glimpse of the energy crisis to come has been the price increases at the gas station. Additional...
--------------------------------------------------------ABSTRACT-------------------------------------------------Due to depletion of fossil fuel reserves and increasing cost of the petroleum products are the big troubles of today's world .from past to present, tendency of oil price have increased consecutively. Especially, India has deficient amount of fossil fuel .for this reason, India has to...
The muskrat (Ondatra zibethicus) lives in both modern and prehistoric wetlands. Sexual dimorphism is a characteristic of many species that is relevant to both modern behavior, such as the partitioning of resources, and the accurate assessment of fossil populations. If sexual dimorphism is present in muskrats, what is known about their interaction with the environment may be inaccurate, as could...
Fossil fuels developed from ancient deposits of organic material, and thus can be thought of as a vast store of solar energy from which society meets >80% of its current energy needs. Here, using published biological, geochemical, and industrial data, I estimate the amount of photosynthetically fixed and stored carbon that was required to form the coal, oil, and gas that we are burning today. T...
Given the increasing importance of sustainability aspects in national energy plans, this article deals with the prospective analysis of life-cycle indicators of the power generation sector through the case study of Spain. A technology-rich, optimisation-based model for power generation in Spain is developed and provided with endogenous life-cycle indicators (climate change, resources, and human...
In recent days, fossil fuel resources are decreasing day by day while the population number is continually increasing. This is why many researchers make their efforts to find new sources of energy, especially the renewable ones to compensate the deficiency of fossil energy. Biodiesel fuels are making its place as a key future renewable source and are attracting increasing attention worldwide as...
The current fossil fuel-based generation of energy has led to large-scale industrial development. However, the reliance on fossil fuels leads to the significant depletion of natural resources of buried combustible geologic deposits and to negative effects on the global climate with emissions of greenhouse gases. Accordingly, enormous efforts are directed to transition from fossil fuels to nonpo...
