Today energy Is still needed to cook our DOD and make our daily lives easier thus satisfying the original need. Although energy is still necessary, I believe humans use too much Reference: Barbecue, A. J. (2006). Energy: Physical, environmental, and social impact (3rd De. ). Upper Saddle River, NJ: Pearson-Prentice Hall. WOK -SQ: What Is the connection between population growth and energy use? How are each interrelated to the supply and demand of energy consumption and creation? Explain your answer. The increase in population is supported by the steady increase of our use of energy.
Modern society is dependent on a massive amount of energy. If that energy were not available or If it declined at any significant amount, It could have a detrimental effect on the population. Should energy supplies decline, price will increase, and the economic challenged population may have to go without needed fuel or electricity. If they are already below a sustaining level, this could be tragic. WOK-SQ: Why is it more expensive to transmit electricity locally than over long distances? Please list various reasons for this.
Why would an energy plant want to distribute electricity locally If there are fewer profit margins? According to Barbecue (2006), ten recent of electric energy is lost in the transmission process. Of the ten percent, eight percent is loss locally. There are higher losses of energy at very low distribution voltage. Therefore, the cost to transmit electricity locally is more expensive. The Increase in market share, market growth, and no way to storage unused energy, would be reasons why an energy plant would want to distribute electricity locally even though profit margins were less.

WOK-SQ: Explain what is meant by base load, intermediate load, and peak load. Why are these concepts important to understanding the production of electricity and energy management? How do these relate to the end users of the product? According to Barbecue, base load is the basic amount of electricity that is always required. Base load is generated by the utilities large facilities. Intermediate load is the amount of electricity that slowly cycles on and off. Peak load is the time in which demand for electricity is the greatest. Peak load is usually only a few hours a day.
Utilities meet peak load demand by using additional generators that can be stated quickly. Electricity cannot be easily stored. Therefore, demand has to be anticipated by the utility company. Season and time of day are the predominate drivers of consumption. Enough electricity needs to be supplied to meet demand on the hottest day of summer. Maintaining a reliable electric system without interrupting power to the consumer cannot be accomplished without the balance of supply and demand. Describe the extent of damage done to the power grid during Hurricane Strain in Mississippi, Texas, and Louisiana.
Explain major concerns that plagued electric utilities during the restoration phase. What effects did the demand for electricity have on assorted load requirements in these areas? Why was electrical load an important issue? WOK-SQ : Should the world be concerned that China, with enormous coal deposits, is undergoing explosive economic development? Explain why or why not, with reference to pollution control. How does this deter the U. S. Energy sector from pushing towards a more costly, but greener means of energy production? The world should be concerned that China is undergoing explosive economic development.
China consumes the most energy in the world and is expected to increase its demand by 75% between 2008 and 2035. China is the largest producer and consumer of coal. 0% of China's energy supply is produced by coal. China produces more carbon dioxide than any other country in the world. If China's carbon usage mirrors it's economic growth, by 2030 its carbon dioxide emissions would equal Honestly, I would think with stats like the above would motivate other countries to be responsible and produce clean energy regardless of the cost. The world, not Just China or the U.
S. , needs to take drastic steps to produce clean energy. Http://www. China-mike. Com/facts-about-china/facts-pollution-environment-energy/ WOK-SQ: What is the reason that nuclear utility plants are so expensive? How is nuclear power's cost different from that of coal burning plants? Why and when would you choose one over the other? Explain your answer. Nuclear utility plants are so expensive because of the capital cost. A 1,000-megawatt nuclear unit is estimated to cost $10-$12 billion to construct. A plant generally consists of more than one unit.
The cost of producing electricity using nuclear power is less than that of a coal-fired plant. In 1999 the cost to produce a kilowatt hour for coal was 2. 07 cents, for nuclear it was 1. 83 cents. I believe there are many factors that need to be considered in using one over the other. Safety, the effects on the environment, emissions, waste, delivery to the consumer, location of fuel, sustainability, and reliability are a few. References: http://FL . Pebble.

C=Electricity,Benefits_^Effects WKWOKQSQAmong the various strategies for producing energy, how are the various renewable resources similar in how they produce electricity? What differentiates them mechanically from each other? Which renewable resource is the most difficult to manage? How do these various sources compensate for expansion? According to AuBarbecue2006), renewable resources are similar in that they are all products of the energy delivered by the sun. The energy from the sun warms the earth, "and drives the winds and the ocean current" (pgpig54). The mechanical difference is the sources themselves. The sun provides heat/sun ray which is captured via solar panels, it drives the wind which move the blades of a windmill, and it drives the water current used by water mills or dammed to generate energy. Each resource has its advantages and disadvantages in terms of management. To say one is easier than the other is relative. It is my opinion that renewable resources ominsensateor expansion by being replenished. WKWOKQSQWhat is the main cost driver of renewable energy production?
How does this differ from nonrenewable energy costs? Aside from environmental implications, why would energy companies lean towards a more costly means of producing energy? The main cost driver for renewable energy production is the cost of capital. After the infrastructure is in place, the fuel is free. This is not the case for nonrenewable energy production, where fuel prices can be volatile and supply is finite. The benefit of an infinite supply of free fuel would cause energy organizations to lean towards a ore costly means of producing energy.
