The main aim of this report is to identify the different sustainable forms of energy and their technological principle which are under substantial development replacing the conventional or traditional forms of energy. It is also the objective of this study to indentify the advantages and disadvantages of each system of energy in their actual application now and in the future. In addition, the report discusses the different Efficient Energy Management systems, which are currently in use....
The aim of this study is to discuss the vulnerability of two cotton growing regions in India to climate change in regard to water availability and pesticide use. Three variables namely, precipitation, irrigation and pesticide, have been used to look at water conditions, yields and farmers' livelihoods, in the two regions and also how future precipitation (due to climate change) will affect these conditions. Can these variables tell us something about the system's capacity to handle disturbances...
Introduction Concerns over disruptive fossil fuel markets, uncertain pricing and significant environmental consequences have placed greater emphasis on sustainable energy policies that include the significant development of renewable energy supplies. With rapid economic growth in newly-emerging economies, demand for energy around the world is increasing at an alarming rate. The International Energy Agency predicts that 93% of this increase is expected to come from newly-emerging economies like...
The climate change and forests are interlinked. The increased destruction of the rainforest forming a precious cooling band around the Earths equator is recognized as one of the main causes of climate change. Forests trap and store carbon dioxide, playing a major role in mitigating climate change (Madonna, n.d.). Forests compensate for fossil fuel emissions through carbon storage; and to enhance ecosystem health, sustainability, and resilience.(Denman et al., 2007).Fossil fuel as a...
Water is the most abundant substance on the face of the earth, and animals and plants likewise need it to sustain life. Outweighing land on Earth three-to-one, it has the potential to be more destructive than it can bring life. When most people think about the destruction that water can bring they think about hurricanes, floods, and droughts. Compared to acid rain, it is arguable that these are minor problems, considering that they do not occur very often. In discussing acid rain, it is...
Climate change and invasive species have been a challenging problem in this global change. When many stresses act in synergism they may eventually have unexpected and irreversible consequences for the native communities and also may impact economically valuable human activities such as fisheries in a particular region (Ambrogi, 2007). To avoid and minimize impact of invasive species, appropriate detection and control should be determine to achieve optimum result, include considering influence...
In this assignment, I will learn about the outcome two that is Newton's law and harmonic oscillation. Newton's law can be divide by three types that is 1st law, 2nd law and 3rd law. It is teach about the motion in our real life. Thus, harmonic oscillation can be divided by three types that are pendulum oscillation, damped oscillation and mechanic oscillation. All of these oscillation are useful in our life especial is use in different type of mechanics.Question OneResearch on the Newton's Laws...
With rising fuel costs, concerns about Climate Change, and the growing demand for power from the developing world, the question that is on everybody's mind is, "How should we generate electricity?" Do we really need Nuclear Power or are there other methods that are better? The 20th and 21st Century The last two centuries saw energy efficiency increase enormously, in areas such as motive power, electricity generation, lighting, the conservation of heat, and in many other applications....
National rural electrification policies and programs, together with international donor programs, have employed renewable energy as an adjunct to "access" strategies, thereby serving increasing percentages of rural populations who do not have access to central electric power networks. An estimated 350 million households worldwide still lack such access. In Africa, the share of rural populations with access to electricity is extremely low in many countries-for example, 24 percent in...
MEANING OF WASTE WATER TREATMENT: Domestic wastewater treatment or sewage treatment, is the process of removing contaminants from wastewater and household sewage, both runoff (effluents) and domestic. It includes physical, chemical, and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce an environmentally-safe fluid waste stream (or treated effluent) and a solid waste (or treated sludge) suitable for disposal or reuse (usually as farm...
