Summary — The Whole Chapter in One Scan

Aims & hypothesis come first — they turn a vague curiosity ("what do people think of this wind farm?") into a testable geographical question.
Site selection uses sampling (systematic, random, or stratified) to avoid bias — and sometimes an opportunistic approach is needed if access is limited.
Equipment is simple and purposeful: clipboard, EQS sheet, questionnaire, pencil, camera, and — uniquely for energy fieldwork — a digital decibel meter for noise.
Risk assessment is essential before any fieldwork — weather, traffic, unfamiliar places, and talking to strangers are the classic energy-fieldwork risks.
Questionnaires mix open, closed, and statement questions to gather both qualitative opinions and quantitative data.
Environmental Quality Surveys (EQS) score features like litter, traffic, and green space on a scale (e.g. −2 to +2) to compare sites objectively.
Photographs & field sketches are qualitative primary data — useful for capturing detail and can be annotated (not just labelled) for deeper analysis.

1. Aims and Hypothesis

Every piece of fieldwork starts with a question. In an energy enquiry, that question is usually about a development like a wind farm or renewable energy plant — something being built, or already built, that changes the local area.

Think of it like this: you wouldn't set off on a road trip without deciding where you're going first. The aim is your destination — a broad statement of what you want to find out. The hypothesis is your prediction about what you'll discover when you get there — a statement you can test and either support or reject with your data.

Key Distinction An aim is a question or purpose ("investigate the impact of a new renewable energy plant"). A hypothesis is a testable prediction, phrased as a statement, not a question ("environmental quality will increase with distance from the plant").

Typical energy-enquiry questions that lead to aims include:

What are people's views and opinions regarding a new wind farm?
Why do people have the views and opinions they do?
What environmental impact does a new renewable energy plant have on the surrounding area?

From these, you can write clear aims and hypotheses:

Type	Example
Aim	An investigation into the impact of a new renewable energy plant
Aim	An investigation into people's opinions of a wind farm expansion
Hypothesis	The environmental quality will increase with distance from the new renewable energy plant
Hypothesis	People living in the local area will be opposed to the expansion of a wind farm

Once the aim and hypothesis are set, four practical steps follow, in this order:
