Case study: Understanding the trade-offs of alternative energy sources

1. Welcome

Renewables play a fundamental role in our transition away from fossil fuel energy sources to more sustainable options. However, no energy source is perfect, and it is essential to understand both the benefits and different potential impacts.

Evaluating different energy sources enables communities and individuals to select the most appropriate energy source for their location and needs. Knowledge of trade-offs is not only important for the evaluation process but also ensures that informed support or challenge of investment decisions based on environmental, social and justice considerations.

You may be: 

• Considering different alternative energy sources.  
• Interested in the benefits and trade-offs of different energy types. 
• Making decisions about how to address or mitigate against trade-offs. 

By reviewing this case study, you will:

• Understand why examining the benefits and potential impacts of renewables is important. 
• Be able to name some key benefits and potential trade-offs of different alternative energy sources. 
• Develop an understanding of how trade-offs can be addressed. 

Every1 case studies aim to support conversation, reflection and action on a key topic. Case studies provide key facts, examples, practical advice and reflective questions.

We would love to hear your thoughts on this case study! Please complete our short survey.  

2. Factsheet

Let's take a closer look at the benefits and potential trade-offs of five key renewable energy sources. In this fact sheet you will:

• Find out why the impact of renewables is important.  
• Examine some key benefits and trade-offs of five different alternative energy sources.
• Consider one example of how balancing trade-offs works in practice.

Time to reflect: Based on this video, what local factors would be important to consider when choosing a renewable energy source for your community? 

4. Reflective Questions

If you’re evaluating different alternative energy sources, you may want to consider:

• Which trade-offs matter most in your community?
• Energy justice: Who benefits from – and who bears the impact of – renewable energy projects?
• Cumulative impacts: Whilst a single solar panel has minimal impact… what happens when thousands are deployed?
• Life-cycle assessment: What is the life cycle of a particular energy source? What emissions and resources are used to produce the equipment needed? How will you dispose of a particular technology when it reaches the end of its life?
