Energy use
Global Issue:
Why energy use is a problem:
Energy use isn’t just some far off thing that affects nobody, in fact, it affects most people’s everyday lives. Many issues arise from the use of energy: greenhouse gas emissions, acid rain, climate change, and dependency on depleting supplies of fossil fuels— especially from politically unstable regions of the world. It also increases land pollution when renewable energy isn’t used as well as water and atmospheric pollution. 1
It’s actually not really the energy use that’s the problem, it’s the way we harvest it. On one end, petroleum is a non-renewable energy source that isn’t particularly environmentally friendly either, but on the other hand, there’s hydro-electric power, tidal energy, wave power, biomass, wind energy and solar energy which are both renewable and environmentally friendly 2
Statistics:
Actually, energy usage is also not a bad thing if we use it in minimal amounts, but research has shown that this is not the case, even though we (Australia) have been improving slightly over the last few years. As you can see, in 2001-02, the amount of energy used was 175 000 GW per hour, that figure had increased to 200 000 GW per hour in 2007-08 which is when energy use peaked. In that year, we used around 80% of our energy from coal which is a non-renewable energy source. After that, we can see a definite downhill slope that tells us Australia is not-only using less energy overall, but is also using a much smaller amount of coal, the same amount of natural gas used and larger amounts of hydro-electricity and wind energy used.
Why are we doing about are current situation:
As you can see, we have been using declining amounts of energy since 2007-08, but how? Mostly because most of our appliances have become way more energy efficient than before. As we are mainly depending on our appliances for most of our work, this makes a huge difference.
Case Study 1:
What I chose:
I chose the coal mining industry in Australia for my case study in energy.
Spatial dimension:
Well obviously this take part Australia, but the particular parts of Australia produce lots of coal. The part of Australia that produces the most coal is
The Energy We Use Kaplan University Prof: Dr. Allen The Energy We Use We don’t even think about it when turning on our TV’s or Laptops, or even our Cell Phones that they are all using energy and the kind of energy that isn’t always renewable. Imagine walking on the sidewalks in New York City and you come to find that the lights are out and its pitch black. There has been a power outage at a local power substation where power is condensed. Some forms of energy that I rely on, well on an…
Before the Industrial Revolution the United States energy uses were very simple. Animals were used for transportation by land, and win was used to navigate the waters. Animals were also used for labor in which man power was not enough to get the job done. Flowing water was captured and used to run mills and boats. Eventually steam engines took the role of most of these techniques. They were used to power vehicles, factories, and farming equipment throughout the country. The popularity of the…
No. We should not continue using oil as the major source of energy. ------- Student ID: ------ 1st year, --- Professor --------- Workshop 1 class EE July 2, 2014 For the past several decades we have been relying on oil as our major source of energy. It is oil that driven the industrial revolution and turn the global economy into what it is right now. However, the increasing rate of our reliance and hunger for oil has been causing us devastating problems so awful that we can’t afford to ignore…
Energy gives us one more tool to use to approach physical situations. When we were analyzing situations in terms of forces and accelerations, we would usually freeze the action at a particular instant in time, draw a free-body diagram, set up force equations, figure out accelerations, etc. With energy the approach is usually a little different; often you can look at the starting conditions and the final conditions and not have to worry about what happens in between. The initial and final information…
Energy is the ability to do work. Work is the product of force and distance. Energy is used every day and everywhere. The nuclear reactions in the sun releases heat light and other electromagnetic energy. Corn uses that energy to grow. The corn stores chemical metabolic energy. When the chicken eats the corn it stores energy in itself. When we chicken we store energy inside of us. Then we use metabolic energy and turn it into mechanical energy by pedaling a bike up a hill. The pedaling of the bike…

are many different types of renewable energy resources that can be used. These include wind energy, solar energy, geothermal energy etc. renewable energy sources have immense impairments, for example, having to use all of the assets to produce a wind plant, or utilizing a lot of area to have huge amounts of solar panels. But, one of the advantages of these renewable resources is that they can restock themselves and can be used as many times as necessary. An energy source that does not destroy the environment…
the following questions: How do you use energy every day, including electricity, transportation, water heating, etc.? How could you have used less energy? Are you willing to make such changes to decrease your energy use? Why or why not? When you are finished, put your essay in the Chp. 15 & 16 Essay drop box.Essay (10 pts): After reading Chapters 15 and 16, write an essay in which you address the following questions: How do you use energy every day, including electricity, transportation…
expect to see a vast change in the way that mankind harnesses energy. Alternative fuels will play a colossal role in what has become one of our generation’s largest challenges, limited supplies of fossil fuels. Scientists have been working for years to develop alternative methods to power the globe given that materials such as coal and oil are not renewable resources. Once they are used up, they are gone forever. New forms of energy have to be developed but what other sources are there and where…
revolution, the demand of energy from human has increased dramatically; simultaneously the emissions of pollutants have increased, which has led to environmental problems and health issues. One could have predicted that the apocalypse of human race is looming should humanity maintain high level of use of energy, particularly in maintaining the use of non-renewable energy. Thermodynamics is an important field of physics where it deals with the relationships between energy and various forms of transformation…
