...renewable energy alternatives to compete with fossil fuels are described. Among them presented in this video were wind power, solar energy, and biomass fermentation. Although each of these energy sources provides efficient energy without extensive harm to the environment from byproducts, they each possess their own challenges while using and managing them. Wind power is generated through the use of a turbine, usually mounted on a tower. The turbine collects wind energy and converts it to electricity which is transferred to your houses breaker pane. Energy from wind powered devices depends on strong enough winds to move the large turbines, which makes the turbines create energy. Without wind to spin the turbines, energy would not be created through this method. Solar energy is energy produced from the sun using panels. Solar panels are very expensive to purchase and maintain. A challenge with using solar panels is the intensity of sunlight affects the output of energy. If the solar panels do not receive enough sunlight, they will not produce enough energy for use. Biomass Fermentation involves converting biomass into ethanol. The fermentation process converts sugars into ethanol using yeast or bacteria which feed on sugars. Ethanol and carbon dioxide are produced as the sugar is consumed. A challenge with using biomass fermentation as a means of energy is getting farmers to collect the material after harvesting to convert it into fuel. In addition to the renewable energy resources...

...Energy Resource Challenges SCI/275 Joshua Dodson 11/04/11 Renewable energy alternatives have many challenges, and managing these resources has become a nightmare. Renewable alternatives such as wind, solar, biofuels, and hydroelectric have become very popular as an alternative to nonrenewable energy resources. The first renewable energy alternative is wind energy. Because wind will always be around, the use of wind turbines is an energy alternative. A big challenge is that we cannot control the wind; some days it is strong and other days it is calm. Solar energy is another energy alternative. Photovoltaic solar electricity is the technology that is most cost effective to consumers in the United States. The greatest challenge to solar energy is that for 12 hours a day we do not have any sunlight, and there are days when it is to cloudy. Biofuels are derived from biomass (organic material) plants and animal waste. With today’s technology we can gather the leftovers from a harvest of corn such as, stalks, and stubble to produce ethanol. The challenge with this process is that it takes a great deal of organic material to produce a small amount of biofuel. Another renewable alternative that was not mentioned is hydroelectricity. The use of dams to produce electricity is very costly, and it takes a great deal of water to generate a small amount of electricity. Nonrenewable energy resources include coal, oil, and natural gas, which pollute our environment. The...

...Energy Resource Challenges Checkpoint SCI/275 August 25, 2010 Bridgette Mack The Alternative video talked about different types of renewable energy wind power, solar power and biofuel. Wind power a method that solely depends on if there is wind that will make these very large turbines turn and if there is no wind they don’t turn. Another type of renewable energy would be solar power and it depends on the sun and uses panels that collect sun light beams and with the use of generators to form energy. You also have biofuel that is use to produce ethanol which comes corn scientist want to use other materials from farmers after they have harvest their land to see if it can also be made into liquid fuel. Having a different method of energy I think would be good especially if these methods aren’t harming our environment but with the good there is some bad. The challenges I think would be with wind energy this object depends on if the wind is blowing strong enough to turn those turbines and what if there isn’t any wind at all that mean there no energy to produces and the solar panel I think would be costly in the begin and they may off in the long run but it would have to take many miles and much land to produce enough of these panels to supply everyone with solar power and what it there is no sun what then. One other source of renewable would be water power which you can produce power from the use of water. I think that we need to start now to find some other way to produce...

...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...

...the uncertainty over future global sources of energy supply With the worlds primary energy needs set to grow by 55% by 2030, and electricity consumption expected to double over the next few decades, managing future need is a global challenge, perhaps one of the most significant of our time. The international energy authority or the IEA estimates that $22 trillion of new investment will be needed by 2030. At the same time, there is the global challenge of climate change and the need to develop cleaner sources of energy in order to improve, or at the very least not worsen, the health of out environment. As oil and gas supplies become scarcer an more expensive, the hunt for new reserves is creating political alliances and the danger of fresh conflicts. China is moving aggressively to find sources of energy imports, potentially setting up a confrontation with the USA over the dwindling resources of the Middle East and Africa. As fossil fuel prices rise, the option of exploiting resources previously considered uneconomic becomes more attractive. It is now possible to pull carbon out of the ground in forms that were once too expensive or too technically difficult to compete with cheap oil and gas. Governments around the world have re-examine their energy supplies, looking particularly at possible indigenous sources of 'unconventional oil'. Canada's oil-sands seem to offer a vast energy resource, but it can only be exploited at considerable cost to the environment. This...

...Introduction Energy is a vital element in all countries’ development. Considering the importance of energy for sustainable development, the United Nations (UN) introduced a global plan in 2012 called “sustainable energy for all (SE4ALL)” to involve all societies in providing global sustainable renewable energy by 2030. The term sustainable development has been defined in different ways, but the most commonly quoted definition is “the development that meets the needs of current generations without compromising the ability of future generations to meet their own needs” (cited in Soubbotina, 2004, p. 9). The renewable energy plays a crucial role in contribution to sustainable development to satisfy the needs of the future generations. This paper...

...access, as the easiest and highest-quality resources are depleted first, and many non-fossil fuel resources will remain costly to produce at scale. Sustainability – action is needed to limit carbon dioxide (CO2) and other greenhouse gases (GHG) emitted through fossil fuel use. Supply security – more than 60% of the world’s known reserves of natural gas are in just five countries, and more than 80% of global oil reserves are located in nine countries, often distant from the hubs of energy consumption. Continued advances in technology and energy-industry productivity are required to deliver affordable, sustainable and secure energy. The shale gas revolution demonstrates the potential impact of such developments. Effective policy We believe governments must set a stable framework to encourage private sector investment and to help consumers to choose wisely. This includes secure access for the exploration and development of energy resources; mutual benefits for resource owners and development partners; and an appropriate legal and regulatory environment with an economy-wide price on carbon. Energy efficiency Greater efficiency helps with affordability – because less energy is needed; with security – because it reduces dependence on imports; and with sustainability – because it reduces emissions. Innovation can play a key role in improving technology, bringing down cost and increasing efficiency. For example, we believe that energy efficient technologies and biofuels could offer...

At the moment we are facing a major crisis in the electricity department where demand of electricity has exceeded what South Africa can supply. Numerous interventions have been implemented by South Africa but it does not seem that those were enough. Some of the challenges may be seen below: “A target of 10 000 GWh” of contribution of renewable energy contribution to energy consumption by year 2013 (The White Paper policy, 2003). The challenge is that the policy did not specify the percentage target credited to municipalities and other sectors and therefore municipalities and other sectors...

...Universal Energy, Inc. The Oil & Gas Crossroads Steve Ferris is sitting in his new office at Universal Energy, Inc. contemplating the importance, as well as the complexity, of his first assignment. Steve has recently joined Universal Energy, Inc. as Vice-President, Business Development after spending the past ten years at British Petroleum. He is excited, and just a bit overwhelmed, with the first task given him by Universal’s CEO. His job is to conduct a thorough environmental analysis that will be used as the foundation for the later development of a competitive land lease proposal for oil and gas production on a plot of land in Colorado owned by the state. The CEO has hired him for his strategic background and reputation for leading teams. Because the bid has a tight time schedule, the CEO has already formed the team Steve will be working with. There are representatives from a cross section of the company including finance, engineering, human resources, management, government affairs, legal, and the relatively new corporate responsibility/sustainability areas. The team’s task is to use secondary sources (no time for primary research) to inform the proposal development team around six basic environments—political, social, economic, regulatory, competitive, and technological. Besides describing the issues, they have been asked to provide conclusions and recommendations going forward to the proposal group. The results of this analysis will be used by the proposal...

...Environment and Development Department of Policy Studies, The Energy and Resource Institute (New Delhi) Submitted on 9th December 2012 Table of Contents Executive Summary 1 Literature Review 4 Scope 6 Conclusion 10 Works Cited 11 Executive Summary The gradual shift of the US gas sector- from one of deficit to one of surplus has gathered appreciative appraisals from the rest of the world and initiated talks about the prospect of harnessing shale gas in other countries, as US reached the lowest CO2 emission level in the last 20 years due to shift to natural gas. It has been referred to as “the biggest energy innovation of the decade”, in light of the growing need for suitable alternatives to conventional oil and gas with increasing pressure on energy over time. 90% of global shale gas is currently produced by the US. India meets two-thirds of its petroleum requirements by importing of fuels that include coal, and this figure is expected to rise in the future in spite of India being a coal-rich country. Even with introduction of more efficient technologies and cases of higher CO2 emission reduction, our country’s import dependence on petrol, oil and gas will significantly rise in the future, raising the pressure on the resources. This concern for energy security calls for further research in technological solutions for greater efficiency and control. With that backdrop, India’s Integrated Energy Policy (IEP) in its policy proposal has stressed heavily on the...
