Alternative Energy Options

As you know, our world is heavily dependent on fossil fuels for meeting our energy needs. In Chapter 6 of Contemporary Environmental Issues, you have read that there is concern about the possibility of reaching a peak in oil production, and even coal and natural gas will eventually run out. (Next week, in Chapter 7 of the textbook, we will read about an even more pressing reason for no longer relying on fossil fuels: global climate change.) Chapter 8 of Contemporary Environmental Issues introduces a variety of possible alternative energy sources, including nuclear power and many renewable options like wind power and solar energy.

Next week, you will be participating in a collaborative project aimed at developing an alternative energy plan for a particular community – the details of which won’t be revealed until then. For now, let’s all pool our research into what possible energy choices might be able to help us move away from fossil fuels.

In your main post this week, please

• Identify two alternatives to fossil fuels that are currently available.
• Discuss the barriers that keep these alternatives from replacing coal, oil, and natural gas as our primary means of energy.
• Discuss the role that government plays in ensuring a transition to these renewable alternatives in a post-carbon world.

Be creative here – the ideas you explore now might become the building blocks for next week’s sustainable energy plan.

Your initial post should be at least 250 words in length. Utilize at least two scholarly or reputable resources and your textbook to support your claims, using the Scholarly, Peer Reviewed, and Other Credible Sources (Links to an external site.)Links to an external site. document for guidance.

Hi Tutors!

Please, help with math forum:

One common type of calculation that is made frequently out there in the real world is a “fixed and variable cost problem” – it’s a “lump and per” scenario. You pay a fixed cost (or a lump sum) to rent the car, or have phone service. Then, in addition, you have to pay a variable cost (so much per mile or per minute). People use math all the time (or should!) to decide which company has the best plan for their needs.

For the purposes of this Forum, we are going to discuss a subject near and dear to everyone’s heart these days – the price of operating your vehicle. To do this, we need to collect three types of data – our fixed costs, our variable costs and our usage. If you either don’t own a car just borrow a friend’s data or use a hypothetical example based on internet research. One student even did the analysis on his aircraft carrier!
Please click on Start a New Conversation and make the subject of your post your car’s year and model (2012 Toyota Camry, Brooklyn, NY), so that people can tell at a glance which postings might be of the most interest to them.

Presenting data to others in a clear and understandable fashion is an important skill for many people in the workplace, not just mathematicians. For your initial post give a full and complete answer to the following questions in outline form, following this model. Be sure to actually answer the questions – do not get sidetracked on the current prices at the gas pump. Your initial post should be at least 150 words.

Although most Americans view their car expenses as an inevitable part of life and not part of their actual car calculations, we are going to figure out what our car expenses really are.

A – What are your fixed monthly car expenses? (1 point)

I want you to add up all the payments that you must make (car payment, garage rent, license tags, insurance, etc.)–regardless of whether or not old Betsy ever emerges from the garage. If you only pay insurance once a year then divide that number by 12 to add it to your monthly fixed expenses. You don’t have to share the specifics if you would prefer not to–you can just give the total.

B – What are your variable monthly car expenses? (1 point)
Add up your variable expenses—the ones that depend on how many miles you drive the car. Don’t get into the nitty-gritty of your car’s miles per gallon—just give an approximation of what you spend each month on variable expenses (gas, oil, washer fluid, car washes, etc.).

C – What is your total cost per month? (1 point)

Add your fixed and variable costs together.

D – Approximately how many miles do you drive a month? (1 point)

All of the discussion in the media is about the price of gasoline per gallon, but to calculate your personal cost, a more relevant statistic for you is your cost per mile. That is one of the things that you should consider when you decide whether or not to drive home for lunch.

E – Divide C by D to figure your cost per mile. (1 point)

Pay attention here. If the money is more than the miles, the cost is over $1.00 per mile – if the miles are more than the money, the cost is under $1.00 per mile. What is your cost per mile?

Surprised? One student did the calculations wrong and got that she was spending $316.00 a mile. That would go way beyond surprised!

F – What changes might you make to save money on your total car expenses? (1 point)

Another student lived in a big city and only used the car on weekends. When he finished the calculations, he cut a deal with a local car rental company, sold his car, and wound up renting a very nice car every weekend for less than he was spending on a car of his own

Before you start, look over the instructions for the Unit 3 Assignment. This Discussion will assist with forming your responses for the Assignment.

First, think about a health problem that you find interesting, such as a disease outbreak, chronic condition (heart disease, diabetes, etc.), or common injury in a population (falling among seniors, occupational injuries, etc.). You could also choose a health problem that is currently affecting your community.

Next, choose and research an organization that is part of the public health system (local, state, federal or global health organization, non-governmental organization, or other organization) that is addressing the health problem.

For your initial response to the Discussion, provide a brief description of the public health problem and the organization you have chosen. How is the organization actively addressing the health problem? Who are the stakeholders in the community that the organization might reach out to in partnership to address the problem?

Your two peer replies should ask probing questions about the organization or the health problem that is being addressed by your peers. You can also make additional suggestions to your peers regarding other stakeholders or organizations that might be appropriate to include when addressing the public health problem.

Be sure to include a list of credible references to support your response.

Classmate Post #1

Hello everyone,

This was a very interesting topic to discuss this week, because I got to see all different types of organizations, and how many of them come together to help the community. The health problem I decided to choose was diabetes. I found a few different organizations that target diabetes, since it is such a large and deadly problem. The organization I chose was CDC’s Division of Diabetes Translation (DDT). Diabetes is a disease when the human body cannot produce or respond to insulin. Since diabetes is such a large problem, with 729 million people in the United States suffering from it, I decided it was an issue that needed to be paid attention to (“Diabetes Home,” 2018). Many people have prediabetes, while other people do not even know that they have it. It is important for people to know whether or not they have diabetes, so they can get the proper treatment. If gone un-treated, this can lead to heart disease, strokes, blindness, amputations, and even death.

The DDT program helps people with diabetes by funding states and local health departments to support their programs and activities that they provide. These programs and activities being supported and funded, help prevent or delay type 2 diabetes. Funding from the organization also goes towards improving any health outcomes for people suffering from diabetes. Funding programs in local communities and all the different states is extremely important, because it can help people who are struggling financially get help for their disease. In my opinion, people should not have to worry about their health with diabetes just because they are unable to afford help. This organization is great at helping address the problem of diabetes by not only targeting diabetes, but also targeting other diseases that can cause diabetes as well. This organization is about prevention, so that people can get the support they need without also worrying about being diagnoses with other diseases due to diabetes. DDT will help with the funding of obesity programs as well, so that people have a less likely chance to become obese, which can develop into having diabetes.

The stakeholders in the community that the organization would reach out to would be the specific state’s health department. State health departments are in charge of certain support groups and support activities that the organization would be funding. This organization also helps schools that are having diabetes and obesity problems. This would mean that another stakeholder that the organization would reach out to would be the school’s super intendent or principals of schools. Community programs are the main source to help people suffering from diabetes; so, this would mean that anyone that is in charge of support programs would be the people to talk to about setting up funds from the organization.

Classmate Post #2

For this discussion topic, I chose to research Polycystic Kidney Disease. Not because I think it’s interesting but because I know I need to educate myself on it. PKD runs in my family and I have always avoided going to get myself checked. My grandfather on my mother’s side was diagnosed with it and passed very young, when my mother was only 16 years old. My mother inherited the disease, and just recently my brother had an accident at work and when he went to the doctor, they diagnosed him as well.

PKD is defined as a genetic disorder that causes many fluid-like cysts to grow in your kidneys (National Institute of Diabetes and Digestive and Kidney Diseases, 2017). The Polycystic Kidney Disease Foundation is the only organization in the U.S. solely dedicated to finding treatments and a cure for PKD to improve the lives of those it affects (PKD Foundation, 2018). Thankfully, On April 24, 2018 the FDA granted approval of Jynarque to be the first treatment in the U.S. for adult patients with PKD (PKD Foundation, 2018). Not only did the PKD Foundation support early studies that led to the development of Jynarque, they also helped guide patients to the clinical trials. If the PKD Foundation isn’t already partnered with the Otsuka Pharmaceuticals, who developed Jynarque, they will be in the near future to spread the word of this treatment.
