Current patterns of production and consumption of energy in Nigeria are unsustainable, and damaging the environment. As an energy rich country (oil & gas) whose economic need is great, it is essential that energy supplies be developed sustainably; to support economic and social development. The main objective of this research is to critically analyze current energy production and usage patterns, and to identify technical and policy opportunities for greater sustainability of the energy...

We have chosen the pink salmon index stream near Ketchikan, Alaska called Carroll Inlet for our research paper. Maintaining Carroll Inlet is vital to the survival of pink salmon in this estuary. An array of threats has the potential of affecting pink salmon, the largest being overfishing. To protect these fish from future harm, we propose a management plan that provides guidelines against overfishing as well as plans for tests to be made to make sure that we properly preserve pink salmon...

Transesterification is the basic process involved in biodiesel production. In transesterification, fats or vegetable oil reacts with an alcohol in the presence of a catalyst like caustic soda(alkali) to produce a mixture of fatty esters and glycerol.The diesel engine is an internal combustion engine in which the high pressure and temperature conditions associated with the compression stroke are utilized to ignite and burn the diesel-fuel mixture within the combustion chamber. The energy...

India has a severe electricity shortage. It needs massive additions in capacity to meet the demand of its rapidly growing economy. The countrys overall power deficit�11 percent in 2009 has risen steadily, from 8.4 percent in 2006. About 100,000 villages (17 percent) remain unelectrified, and almost 400 million Indians are without electricity coverage. Indias per capita consumption (639 kWh) is one of the lowest in the world.The Integrated Energy Policy Report, 2006, estimates that India will...

The need for renewable energy resources couldn't be more desired than now. The article "Contribution of Renewable Energy Technologies to Future Energy Requirements "was written in 1984, it explains what potential renewable energy could have on many nations. This article was written by D.H. Buckley-Golder, R.G. Derwent, K.F. Langley, J.F. Walker and A.V. Werd to allow us to understand why renewable energy resources need to be developed and used. The time for research and development...

Sustainability is a subject that has become very popular in the recent years as global concern on climate change and growing population has taken more importance. What is more, sustainability is starting to grow in popularity as a costumer concept (Ekvall, et al, 2004). Therefore, businesses are now under legal, economic and commercial pressure to operate in a sustainable way. While some firms have implemented sustainable polices and schemes often facing compromising decisions at the time of...

Environmental conditions are always critical factor for plant growth and development. Among these environmental conditions, the three leading and ecologically important factors are plant light, temperature, and water. Especially in case of light that is the sole source of energy, play a major role for plant growth. The Light has particular dramatic effect on morphological characteristics such as leaf morphology (leaf anatomy and leaf size), plant elongation, axillary shoot formation,...

In terms of health safety and environment some commitments must be present in oil and gas companies, no matter what how big or small size they are. Regarding health, it must prevent risks in the workplace and in the nearby areas, fight against epidemic diseases causing serious social consequences and create schemes for the management of health in case of emergency.The commitments of safety are based in avoid workplace injuries with high standards of requirement in the safety management and...

Whilst proactive actions to reduce the risks posed by hazards in the future are important, the institutionalization of disaster handling should be able to arrange clear mechanisms and procedures in order that impacts do not affect disaster victims too long. Dealing with the importance of disaster handling institutionalization, Dwiyanto (2006:37) suggests the need to revitalize disaster management institutions. Things to be considered are that (1) Disaster management should be conducted...

The introduction of hydrogen into an energy system requires substantial changes and investments of infrastructure. Most publications agree that this is the main barrier to the development of hydrogen as an energy carrier. Hydrogen used in HFCVs can be produced in a centralised production plant or a decentralised on-site station. Hydrogen from the former can be distributed via pipelines, liquid hydrogen tank trucks, etc [39]. Fig. 3-14 exhibits the most possible ways to produce, distribute,...
