2. Energy Sources and Consumption Level
a) Fossil Fuel: Oil, Nature Gas and Coal
Oil
China is the second largest oil consumer and oil importer in the world.(EIA,2013) The demand of oil is driven by the rapidly growing economic and the large population. Oil consumption is also influenced by Chinese government’s energy polices, national oil companies and oil imports. In order to perform more efficiently the Chinese government has improved their policymaking and implementation capacity. Nation oil companies dominate the production of China’s oil. They also do oversea acquisition to meet the increasing demand of oil and develop more qualified technicians. China’s oil imports are increasing over years. It predicted that China will become the largest oil importers by 2013. Most of China’s oil fields are located onshore. They are more mature and the productions are approaching the peak of capacity. Now, China is more concentrated on developing fields which are located in new western interior provinces and offshore.
Nature Gas
The consumption of nature gas is rising very fast. In 2007, China became to be a net import of nature gas since the Chinese government promoted the consumption of nature gas to reduce the pollution from the use of coal.(EIA,2013) The major source of natural gas are from southwest of country and offshore fields such as Yellow Sea and South China Sea. Government encourages to developing more fields, pipelines and advanced technology to satisfy the rapidly growing need from corporations, factories and residences. China is also focus on importing more natural gas and building more pipelines from neighboring countries.
Coal
China is the largest producer of coal in the world. (EIA, 2013) Coal is the first primary energy in China. Before 2009, China is a net coal exporter. After 2009, China became a net coal importer. (EIA, 2013) In the past,…...

Alternative Energy Sources

...Alternative Energy Sources Geology Many people believe that we must depend on fossil fuels for energy, where as the reality of it is the earth provides an abundance of renewable energy sources. These energy sources can produce enough energy that we would never have to use fossil fuels again. Alternative energy is the use of other energy sources instead of the use of fossil fuels or nuclear energy. Solar power can be used to operate cars and provide electricity to homes and businesses. Hydropower can be used to provide electric power to small towns and cities. Geothermal power can heat up buildings or water to power turbines to make energy. Wind power can be used to pump water and generate electricity. So let’s start with solar power since it is the most known of the group. Energy from the sun is one of the most abundant resources available today out of the alternative group. It is one of the most important of the non-conventional energy sources as well, because it does not pollute the earth. “One of the reasons for this is that the total energy we receive each year from the sun is around 35,000 times the total energy used by man”. (Alternative Energy Sources) One way to capture the sun’s energy is through the use of solar panels made out of Photovoltaic cells, which are commonly called (PV) cells. These panels can be used on homes, businesses, greenhouses, water heaters, traffic lights, or grouped together as a solar power plant. PV cells can transform the sun’s energy......

Alternative Energy Sources

...Alternative Energy Sources: Ending Human Dependence on Oil Craig A. Rockwell SCI 207 – Dependence of Man on the Environment Instructor Gomillion July 13, 2012 Alternative Energy Sources: Ending Human Dependence on Oil We live in a world where oil is the primary source of energy. It is used to produce heating fuels, gasoline, propane, and many other lesser-known fuels. Globally, we are consuming approximately 88 million barrels of oil daily. The Central Intelligence Agency (2012) shows that the United States consumes 19,150,000 barrels daily (pg. 1). Many will argue that we need to end our dependence on oil by finding other sources of energy that we can use in place of oil. This is where the question comes in on whether or not alternative energy sources are the answer to ending human dependence on oil. While alternative energy sources may be a big step in reducing our dependence on oil, they are not a solution to it due to our lack of knowledge on how to harvest and use them efficiently, as well as the limits of what they can do for us. If we are going to talk about alternative energy sources, we have to look into some of the sources that fall into the category of “Green Technology”. Sheer (1995) writes, “The economic and social advantages of renewable energies are enormous: they offer the way toward saving both the earth’s atmosphere and human health; they ensure an independent, safe, long-term energy supply as well as economic development; they will......

Energy Sources

...Lloyd 1 Alternative Energy Sources Energy is all around us. Almost everything that you can see or touch is energy or took energy to make. Even our bodies are made up and made from energy and we can also produce energy but it takes energy to do so. So when you think of it in that way how can anyone say that the United States and even the world may be entering an energy crisis? We are though and some parts of the world already have. Even though it maybe true that some sources of nonrenewable energy sources are virtually inexhaustible because of technological advancements. However, these resources such coal, oil, and natural gas are slowly killing us, the environment, and the whole world we live in. This is because fossil fuels such as those previously mentioned give off greenhouse gases such as carbon dioxide (CO2) and sulfur dioxide (SO2) which cause smog and allow harmful radiation from the sun to penetrate our atmosphere. This problem is continually getting worse because we continue to use more and more of these fossil fuels every year. This is mainly because of population growth, inefficient buildings, lighting, and automobiles, and a general wasteful attitude towards energy. In fact 43 percent of all commercial energy produced is wasted unnecessarily because of factors Lloyd 2 such as these. If we could be as completely efficient in energy use as technologically possible we would only need the current amount of electricity provided by the hydroelectric power......

Energy Consumption

...ENERGY CONSUMPTION AND ITS IMPACT ON HUMANS AND THE ENVIRONMENT Americans consume energy in multiple ways: heating and cooling our homes, lighting our offices, transporting ourselves from one place to another, powering factories, among many other aspects of our daily lives and work. Sometimes energy consumption is obvious, as when we pump gas into a car. Many other times it is easy to forget that we are consuming energy. The fact of consumption is hidden by the ordinariness of turning on a switch, altering a thermostat, or cooking a meal. This everyday consumption, however, is massive: with only four per cent of the world's population, the U.S. consumes over a quarter of its energy. When we consume energy, we affect the natural environment. This is true for virtually every kind of energy, although the kind and scale of impact varies greatly. Production of hydroelectric power involves damming rivers and thus harms fish runs. Windmills occupy huge amounts of open space. Even solar energy involves production of batteries and solar cells that have some impact. While all energy production has environmental consequences, the production and use of fossil fuels cause by far the most negative effects, at virtually every step of the way. Extraction of these fuels, such as drilling for oil or mining coal, often destroys forests, mountains, coastlines, and other natural areas. When crude oil is transported by sea to refineries, leaks and spills can destroy marine life for huge areas....

Wind Power as a Source of Energy

...a room that you aren’t in; or falling asleep with the T.V. on (which I do quite often). It could be this, but it could also be the fact that the world’s source of fossil fuel is running out. We may need to switch to other sources of energy in the near future, like wind power or solar power. These changes would also help reduce the amounts of greenhouse (A gas in the atmosphere that absorbs and emits radiation within the thermal infrared range) gasses being emitted into the air, which would help slow down the effects of global warming. Wind is air in motion (Casper), and wind power is a large percent of current energy produced. It can help reduced emitted greenhouse gasses and slow down the effects of global warming. The global wind energy potential is roughly five times current global electricity use (Flavin). Also the price of wind generated energy fell more steeply than any other energy source over the past 30 years (Burnett). The cost of wind power fell from approximately 25 cents per kilowatt per hour (kwh) in the early 1980s to between 5 cents and 7 cents per kwh (Burnett). Advocates argue that a new generation of turbines will bring down the cost to below 5 cents per kwh (Burnett). This would make it much easier for people to be able to afford it. Wind power could provide as much as 6 percent of the nation’s energy (Burnett). It is currently providing less than 1% of the U.S. power supply but could double its shares within 10 years (Burnett). Furthermore, wind power...

The Sources of Energy for Muscle Contraction

...FIS3703 Discuss the sources of energy for muscle contraction Sources of energy for muscle contraction Muscle contraction is dependent on energy supplied by ATP. The majority of this energy is needed to actuate the walk-along mechanism by which the cross-bridges drag the actin filaments, but some energy is also needed for (1) propelling C ions into the sarcoplasmic reticulum from the sarcoplasm after the contraction is over and (2) propelling sodium and potassium ions through the muscle fiber membrane to keep suitable ionic environment for conduction of muscle fiber action potentials The ATP concentration in the muscle fiber is enough to maintain full contraction up to 2 seconds. ADP is formed after it splits from ATP and ADP transports energy from the ATP molecule to the contracting machinery of the muscle fiber. After that, the ADP is rephosphorylated and new ATP is synthesized within a few split seconds which permit the muscle to maintain its contraction. Numerous sources of energy for rephosphorylation exist, the first one being phosphocreatine which transports a high-energy phosphate bond almost the same to the bonds of ATP. Phosphocreatine has a little bit more free energy than that of an ATP molecule. Thus, phosphocreatine is immediately cleaved and the energy released from it results in the combining of a new phosphate ion to ADP to reconstitute the ATP. However, there is not much phosphocreatine in the muscle fiber and thus, the collective energy of the......

Alternative Energy Sources

...Are Alternative Energy Sources The Answer? Jose Ortiz SCI 207 Bradley Wells April 16, 2012 Since the existence of mankind we have depended on this earth for food, shelter, and water. These are the basic necessities that are required for survival. With one of the necessities taken out of the equation mankind existence would become extinct. Worldwide humans have left an ecological footprint on earth that has made it difficult to sustain itself. Mankind has entered in a race against time trying to find alternatives to alleviate some the demands we have this earth and one that comes to mind is alternative energy resources. With oil at an all time high researchers have been searching for alternatives energy sources. The question is: are alternative energy sources the answer to ending human dependence on oil? Although oil has a negative impact on our environment, oil is here to stay as many countries rely on it financially. Investing time and money in alternate energy source has potential rewards for the consumer and ultimately the sustainability of our planet. The possibility of being able to replace a fossil fuel such as oil would be a turn of the century. Fossil fuels are non-renewable in which it cannot be replace or replaced a very slow rate. Once it is used it is all gone (Turk & Bensel, 2011). At the rate of oil being used it is unable to replace itself in the natural process. Not only is there so much oil that can be used, but eliminating oil......

Renewable Energy Sources

...Lanier Meghan Woods Comp I: Thesis Statement 11/11/2014 Intuitive Energy Consumption In modern day society, I have observed the emerging negative impacts on the natural environment and human society from global climate change, and rising prices of traditional sources of energy. These two physical occurrences have led me to view renewable energy development as an ever increasing, promising approach to mitigating climate change, diversifying energy supplies, and even stimulating economic development. CNN news recently reported that in the United States, renewable energy development is a very active policy arena, in which an array of policy instruments are designed and implemented (CNN, 2011). CNN goes on to describe that over the past decade the states have experienced a rapid growth of renewable energy sources with an accelerating rate over the last few years. It is my ultimate and fervent belief that instead of maintaining oil and coal as the predominant energy sources in the United States, more emphasis should be placed on organic and less harmful renewable energy sources. More importantly, how and to what extent do political factors in each state influence renewable energy development practices. The influence of political institutions, interest groups, and government ideologies in the renewable energy deployment process is very substantial in my opinion. Industries driven by oil & coal consumption such as the automotive and other combustion engine......

Sources of Energy

...Sources of Energy The law of conservation of energy states that the total amount of energy stored in a system will be constant throughout time. Since energy remains constant in a system, it cannot be created or destroyed, but it can be converted into other forms of energy (Law of Conservation, n.d.). Other forms of energy use include fossil fuels, nuclear energy, solar energy, wind power, water (hydro) power, and bio-conversion (biofuel). There are both pros and cons in using these various forms of energy. Fossil fuels are a common source of energy used that are naturally occurring substances found on the surface of the earth. It is a non-renewable source of energy. One major advantage of fossil fuels is their availability. They can easily be found on the surface of the earth. However, depletion of this non-renewable source of energy is increasing because of the demands. Therefore, in the future there will a high demand and a low supply of fossil fuels (Energy.gov, n.d.). Nuclear energy is a controversial non-renewable source of energy. According to Maehlum, about twenty percent of the entire electricity generation is produced using nuclear energy. Generating electricity at a nuclear power plant is relatively low in costs as well as low in pollution. However, the nuclear waste is potentially harmful to both humans and the environment (Maehlum, 2013). Solar energy is a renewable energy source. As long as there is sunshine, solar energy will be available. ......

Renewable Energy Sources

...Renewable Energy Sources The Sustainability Revolution John C. Ayers "In a sense, the fossil fuels are a one-time gift that lifted us up from subsistence agriculture and should eventually lead us to a future based on renewable resources." Kenneth Deffeyes (2001) "I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that." — Thomas Edison, 1931 We cannot create or destroy energy. We can only capture it. The sun provides either directly or indirectly nearly all of the energy available to us. Plants capture solar energy directly through photosynthesis. Fossil fuels contain the energy of sunlight captured hundreds of millions of years ago. Photovoltaic (PV) cells also capture sunlight energy directly. Other energy sources capture the energy of sunlight indirectly. Heat from the sun powers the flowing air and water. We usually capture the kinetic energy of wind and water by using turbines that transfer the energy to an alternator, an electrical generator that produces alternating current. Geothermal energy is different in that it captures flowing heat energy produced by radioactive decay in the earth’s interior. In this chapter we will see that Wind, Water, and Sun (WWS) energy sources are sustainable because they are renewable, clean, safe, and nearly carbon-free. Although they have low energy densities, meaning that they require large areas of land or water to produce energy, they......

Renewale Energy Sources

.... Renewable Energy Resources March 1, 2015 To My Great-great grandchildren, RE: PRESERVATION OF THE RENEWABLE ENERGY RESOURCES I want you to know that the renewable energy sources are the cornerstone of our nation. The mentioned sources of energy have historically played a pivotal role in building our economy. The interesting part is that about 9.5 percent of all the energy consumed by our country is from renewable sources. The cited percentage forms 12.9 percent of our country’s total electricity production. Evidently, the most current information from the Energy Information Administration reveals that our nation is the world largest consumer of renewable energy. The above means that our country has consumed solar, wind, wood and geothermal at a greater length. Similarly, our country greatly depended on the use of oil. The transport sector alone consumes about two-thirds of the petroleum energy. Also, building and appliances consume about 4 percent of the said energy. Lighting on the other takes a quarter share of oil energy. The above examples clearly indicate that our nation at greater length relies on the use of the oil and renewable resources. It is very imperative to note that our country is facing myriad challenges in managing the energy resources. Just to mention but a few, energy resources both renewable, and oil energy has in a way caused environmental challenges. The body concern with the management of the mentioned energy has placed less effort in......

Convng to Nuclear Energy Sources

...There is an issue in society that continues to be a concern and needs to be seriously addressed. The problem is that global warming is increasing at a significant rate. According to NASA’s article entitled “Global Warming”, global warming is the unusual “...rapid increase in Earth’s average surface temperature,” (2014, para. 1). Our planet, Earth, has had its temperature changed a significant amount of times throughout history. These changes were due to receiving more or less sunlight from the shifts in the Earth’s orbit. However, scientists have found that over the past century another source has influenced the change of Earth’s temperature: mankind. Scientists from NASA’s Earth Observatory suggests that these significant changes are primarily due to the release of greenhouse gases as people burn fossil fuels, given the fact that the rate of temperature increase nearly doubled in the last 50 years (GlobalWarming, 2014, para. 3). Greenhouse gases allow sunlight to shine into the atmosphere freely. When the sunlight strikes the Earth’s surface, some of it reflects back to space as heat. The greenhouse gases absorbs this heat and traps it in the atmosphere keeping the Earth at a suitable temperature for humans to live in. There are various amounts of greenhouse gases but carbon dioxide, oxygen, methane and nitrous oxide seem to be more dominant (Hunt, 2011, online). However, when too much of the gas is released then too much of the heat gets trapped within the atmosphere. This...

Energy Sources

...Since the beginning of time, mankind has been using energy and converting it to different forms. This conversion of energy from one form to another is known as Thermodynamics. Energy conversion takes place in our every day lives. Many conversions of energy are possible, such as chemical to heat, heat to mechanical, hydraulic to electrical or mechanical. Almost all energy can be converted from one form to another (Kehmani, 2010). Examples of energy conversion can be seen in day to day life. For example, in cars, the chemical energy of fuel is converted into the mechanical energy of the vehicle; in motor electrical energy is converted into mechanical energy, in hydro power plants the hydraulic energy of water is converted into electrical energy, in nuclear power plants the nuclear energy is converted into electrical energy etc. With the Green movement we are seeing increased use of solar energy, such as solar water heaters and solar cookers where solar energy is converted to heat energy (Kehmani, 2010). While mankind has learned to harness energy and convert it to useful forms, Thermodynamics is governed by scientific laws. The first law of Thermodynamics is that energy can’t be created or destroyed (Kehmani, 2010). The second law states that heat energy can only be transferred from a body of higher temperature to a body of lower temperature. The third law refers to the law of absolute zero on the Kelvin temperature scale, stating that entropy of the body at absolute...

...Energy Sources Connie Collins Strayer University Prof. Alisha Etheredge SCI110 July 18, 2012 There are many ways energy can be converted from one form of energy into another form of energy. Three of the ways are through action of forces, which is where gravity accelerates a falling object that converts potential energy to kinetic energy. Gravitational forces, electric and magnetic force fields, and frictional forces are some examples. A pendulum is a great example of potential and kinetic energy working at the same time. When the pendulum swings upward all the energy is considered potential energy, when it begins its downward swing it gains kinetic energy and loses potential energy (The McGraw-Hill Companies, Inc., 2008). Another way would be atoms being absorbed or emit photons of light. Examples of this are photothermal, photoelectric, and photochemical. The last way is Nuclear reaction with examples of fission and fusion (Debian Gnu/Linux, 1999-2011). Technology devices are considered energy converters. They convert electrical or chemical energy into radiant or mechanical energy. For example a light bulb uses electrical energy and converts it into light while the rest is converted into heat. Light and heat are forms of radiant energy. Washing machines convert mechanical energy and ovens convert thermal energy. Our bodies also convert energy into our muscles by converting chemical energy into glucose which in turn converts into mechanical energy to make muscle......
