INTRODUCTION
Energy is of principal significance for a modern developed economy. Severe interruptions in the supply of power can lead directly to an almost complete break of public and private life in the Western countries. This is an essential concern that should be taken into account in any potential state.
Extensive trade and industry growth are expected around the world during the 21st century, thus continuing the trend of the 20th century. As a result, average living standards will rise, leading to a strong increase in energy demand, even if the efficiency of energy conversion increases and the potential of energy conservation are exploited.
In the longer term, the increase in world population and a higher standard of living are likely to lead to a much increased demand for power. The intention of this paper is to provide a background for a dialogue concerning the adequate support of current research programmes and the development of technologies for future energy needs beyond the middle of the 21st century. Fossil fuels
In the last century, world energy supply was mainly based on fossil fuels - oil, coal and natural gas. (Cucchiella 2012)(1) This will not change in the near future. However, in view of environmental concerns, it may prove undesirable to use mainly fossil fuels to meet the growing energy demand. Moreover, limited reserves of natural gas and oil as well as their concentration in certain areas are potential sources of conflict. It is therefore of utmost importance to expand the contribution of alternatives to fossil fuel combustion during the next decades.
Supply of electricity is a key

The United Energy Smart Meter Project

...United Energy Smart Meter Project At the request of the Victorian Government United Energy is currently engaging in “best efforts” to replace the analogue meters on its network with smart meters. Smart meters are an advanced energy meter that measures the energy consumption of a consumer (Depuru, Wang and Devabhaktuni 2011), they allow for demand response energy distribution based on on-peak and off-peak consumption. The benefits of Smart meters are well recognised by many counties with world-wide deployment of digital meters expected to reach 212 million units by 2014, perceived benefits include; energy efficiency, environmental benefits, more consumer choice, better services and greater market competition. (Gerwen, Jaarsma & Wilhite R 2009, Filippini, Hrovatin & Zoric 2004, Victorian Auditor General 2009) About United Energy United Energy is an energy distributor responsible for the infrastructure required to distribute energy from the power station to the consumer. There are currently 16 major distribution networks in Australia with each energy distributor maintaining a monopoly over its designated area. (AEC 2009) Energy distributors own, operate and maintain the network of infrastructure that transports electricity from the generator to the consumer. They do not work directly with the consumer and instead work with energy retailers who are responsible for managing the relationship with the consumer. Energy retailers will bulk purchase energy from an energy generator...

Off Grid Renewable Energy

...Off-Grid Renewable Energy Applications- World Wide School of Electrical and Computer Engineering Abstract: About 1.4 billion urban and rural households around the world remain without electricity access today. 85% of these households are in rural areas and find it geographically challenging to benefit from grid-connected electricity for power supply. In the developing countries, rural areas mainly rely on inconvenient non-commercial resources like wood, agricultural residues etc. as sources of power generation. Hence, Off-Grid power, which can be generated on-site from renewable energy sources such as solar, wind and biomass, plays a major role for the future of rural electrification world-wide. To achieve universal access of electricity, International Energy Agency (IEA) estimates that by 2030 about 171 TWh of Off-Grid electricity will need to be generated for providing power to approximately 210M or 20% of total rural households. This paper focuses on understanding the implementation and impact of three Off-Grid renewable energy systems in three different developing countries. Two of them are successfully implemented and the other is currently under implementation. The fully implemented Off-Grid systems selected for this paper are “Off-Grid Rural Electrification-Ladakh” in India and “Off grid Solar Power System for a rural village” in Malaysia. The system that is currently being implemented is the “Rural Renewable Energy Development Project” in Bhutan. These projects have...

Industrial Revolution

...Why did the Industrial Revolution take place in eighteenth century Britain and not elsewhere in Europe or Asia? Answers to this question have ranged from religion and culture to politics and constitutions. In a just published book, The British Industrial Revolution in Global Perspective, I argue that the explanation of the Industrial Revolution was fundamentally economic. The Industrial Revolution was Britain’s creative response to the challenges and opportunities created by the global economy that emerged after 1500. This was a two step process. In the late sixteenth and early seventeenth centuries a European-wide market emerged. England took a commanding position in this new order as her wool textile industry out competed the established producers in Italy and the Low Countries. England extended her lead in the late seventeenth and eighteenth centuries by creating an intercontinental trading network including the Americas and India. Intercontinental trade expansion depended on the acquisition of colonies, mercantilist trade promotion, and naval power. The upshot of Britain’s success in the global economy was the expansion of rural manufacturing industries and rapid urbanisation. East Anglia was the centre of the woollen cloth industry, and its products were exported through London where a quarter of the jobs depended on the port. As a result, the population of London exploded from 50,000 in 1500 to 200,000 in 1600 and half a million in 1700. In the eighteenth century, the expansion...

Constructing Change: Energy Efficiency and India’s Buildings Sector

...Constructing Change: Energy Efficiency and India’s Buildings Sector   “The urban sprawl is creating unique challenges and opportunities related to natural ecosystems. As a result, policy makers need to think innovatively about a range of issues from land-resource planning to broader ecological and energy implications. The resulting challenges include reducing pollution, increasing biodiversity, managing peak energy demand and cost, heat-stress health implications, and ensuring an adequate supply of water and nutrients.” Radhika Khosla February 21, 2012 In 2008, for the first time ever, the urban population of the world outnumbered that of the rural. This visible trend has escalated over the last couple of decades; projections suggest that by the end of the twenty-first century, 80 percent of the world’s population will live in cities (which occupy 0.05 percent of the Earth’s surface). Rapid urbanization is creating vast opportunities through an unprecedented demand for the construction of buildings, which already account for more than 30 percent of India’s total electricity consumption. In line with expanding development, the country’s buildings sector is expected to increase five-fold from 2005 to 2050. India is at a unique crossroads where two-thirds of the commercial and high-rise residential structures that will exist in 2030 are yet to be built. Implementing energy efficiency in buildings that are being constructed in the next ten years thus presents a singular...

Proposal on Impact of Solar Panel

...IMPACT OF SOLAR PANEL IN LIVELIHOOD IN SOME SELECTED (MD. IBRAHIM KHOLILULLAH, DEPT OF AG.FINANCE, BAU MOB: 01718996557) AREAS OF BOGRA DISTRICT Introduction Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity. Electricity is the prime mover for the advancement of all economic and industrial activities. About 59% of total population live in rural and isolated areas and most of them have no electricity access. This scenario is more acute in the rural and isolated areas in Bangladesh where only about 25% have electricity access ( Energy Bangla, January, 2014 ). Bangladesh is a semi-tropical region lying in northeastern part of South Asia gets abundant sunlight year round. The average bright sunshine duration in Bangladesh in the dry season is about 7.6 hours a day, and in the monsoon season is about 4.7 hours, Solar energy can be harnessed. So, solar panel technology is advised. A total of 3,00,000 solar panels had been installed in more than 40,000 villages of 456 upazilas of all districts of Bangladesh. Daily on average 44 MW electricity is being produced by these solar panels.( Momotaz and Karim,2012).Now a days solar panel is applied in different aspects such as solar based recharging station ,solar cooking etc. It presents an attractive alternative to conventional electricity such as no monthly bills, no fuel cost, little repair and maintenance costs, easy to install any where etc. The solar panel technology is very...

Food in 2050

...MEETING THE WORLD'S FOOD CRISIS IN 2050 Vanessa Lorig BRAE 340 Dance 233 Benali Burgoa May 27, 2011 Introduction The world must manage the impending crisis of feeding nine billion people by the year 2050 if it is to avoid wide-scale famine and malnutrition. The earth's finite resources of land, water, and energy pose an unparalleled challenge in meeting this goal. It is expected that food production must increase seventy to one hundred percent by 2050 to feed the world's population while the amount of land available for agriculture will remain stagnant due to land degradation and climate change. Food waste, difficulties in distributing food to where it is needed, and greater demand by those with money account for why food production must rise beyond the fifty percent increase in worldwide population. People living in more developed countries with expected rising wealth will demand "better" food, often meat-based, that will place greater strain on meeting the world's goal. Meanwhile, historically over the last one hundred years, water use has grown at twice the rate of population growth. The competition for water will be severe in the future due to agricultural use, accounting for seventy percent of worldwide water usage; urbanization of the world's population; and other water needs such as generating hydroelectric...
