In this task, you will select one of the scientific articles from the list below

In this task, you will select one of the scientific articles from the list below to evaluate. In any evaluation, you must make an argument supported by evidence. As evidence, you are encouraged to draw upon material from the article, and also to make comparisons with the readings from this and any other relevant articles.
In the guide below we suggest a structure and some guiding questions to assist you with the assignment.
Scientific articles from which to choose:
Option 1: Davis et al. (2018) Net-zero emissions energy systems, Science 360 eaas9793 (2018) (Links to an external site.)
Write a synopsis of this article in the context of the how Australia could meet its emissions target of net zero greenhouse gas emissions in 2050. What fraction of the green power sources (i.e. those coloured green in Fig 1) could be deployed to meet Australia’s needs by 2050? How does this compare with the global context (Fig 2)? What role will energy storage play in scenarios for 2050? Has the study adequately considered risks?
Option 2: Dowling & Lewis (2021) Long-duration energy storage for reliable renewable electricity: The realistic possibilities, Bulletin of the Atomic Scientists, 77:6, 281-284, DOI: 10.1080/00963402.2021.1989191 (Links to an external site.)
Although this article is written for the US context, write a synopsis of this article in the context of the how Australia could meet its emissions target of net zero greenhouse gas emissions in 2050. Do you agree with the Authors’ premise that 80% of the US power needs could be met with wind and solar and would this be the same for Australia? Provide a brief summary of the main long-duration storage systems proposed by the authors. Would the pumped-hydro options be suitable for Australia? What are the likely barriers to rolling out this option? The article is silent on the proportion of each proposed for the future. What do you see as the capacity needed for each option? What are the risks?
Option 3: Lewis (2007) Powering the planet, MRS Bulletin, 32 2007 (Links to an external site.)
This article was influential in focusing attention of the problems of reducing greenhouse gas emissions and looking at alternatives. Write a review of the article in the context of 2022) and give your opinion on the outcomes of predictions now after 15 years have elapsed. What implications does this have for your conclusions from Workshop 3 for likely scenarios in 2050?
Structure for the report
All reports have an introduction, body, and conclusion through which an argument should be mounted. Below we outline the content that would appear in each of these broad sections.
Your Introduction (~ 100 words)
Your introduction should, in your own words, concisely summarise what the research contributes to what we understand, or the action that might be taken for climate change and/or sustainability.
To determine this, consider the aims, approach, and conclusions of the paper.
Your Body (~ 600 words)
You will want to discuss the strengths and weaknesses of the article. Consider the following questions about the different sections of the article. They will assist you to identify where the strengths and weaknesses may lie.
Consider the article’s key arguments
What is the main argument of the paper?
Does the argument hold up? Do you find it convincing? Why/why not?
Are there gaps in the evidence?
Does the logic follow?
What are the strongest and weakest argument points in the article?
How are the arguments in this article similar or different from the other articles you’ve read on fire during this investigation?
Consider the article’s methods and results
Does the design of the study test the hypothesis?
Have they made any assumptions in their methods that have ethical or cultural implications, or that would make their work contestable?
What methods have they used?
What data or evidence did this generate?
Is it clear how the evidence they plan to collect relates back to their aims?
Was their sampling regime or selection of participants representative? reliable? ethical?
Are there uncertainties or sources of error?
Have they utilised primary and/or secondary data?
What is similar or different about the methods in this article to the others you’ve read during this investigation?
Consider the article’s conclusions
Do you think the article assists in addressing climate change, sustainability, environmental or social issues? Why/why not?
Have the authors overstated their conclusions based on their findings?
Do the authors show caution by identifying potential sources of error?
Have the authors considered the breadth of implications from their findings, including any ethical or cultural concerns?
How do the conclusions of this article compare to the others you’ve read during this investigation?
Your Conclusion (~ 100 words)
In your conclusion, you will concisely summarise your position on the article, drawing on the strengths and weaknesses you identified in the body of your evaluation. Do not introduce any new ideas here, rather, reflect on the benefits of the research within the article for sustainability &/or climate change in light of your evaluation.
