Level 1 Environmental Technology revision notes for electrical learners. 15 pages on renewables, net zero, waste, recycling, water and quick-fire facts.

These notes cover the Level 1 environmental lessons one week at a time, from Week 1 to Week 11. Each week opens with the big idea, then gives the key facts and real examples in plain language and clear tables. They were written by a practising electrician and college lecturer, so every topic is tied to real work in building services.

What’s covered:

Week 1 – Energy sources: high, low and zero carbon sources, the carbon ladder, and choosing the right source for a property
Week 2 – Reducing carbon emissions: why buildings matter, net zero by 2050, retrofitting, EPCs and where to find guidance
Week 3 – Environmental technologies: solar thermal, solar PV, wind turbines and heat pumps, how they work and where to site them, plus PV safety
Week 4 – Protecting the environment: preventing and responding to spills, oil storage, protecting watercourses, and being a good neighbour on site
Week 5 – Planning and measuring: reading drawings, calculating quantities, cutting lists, and “measure twice, cut once”
Week 6 – Reusing off-cuts: reducing waste and sorting materials as you work
Week 7 – Safe waste disposal: the duty of care, the waste hierarchy, hazardous waste and WEEE
Week 8 – Recycling materials: how copper cable, metals and rubble are recycled, and what needs special handling
Week 9 – Environmental hazards: asbestos, spills and contamination, and how to respond and report
Week 10 – Water conservation: water-saving fittings, maintenance routines and raising user awareness
Week 11 – Rainwater harvesting: how rainwater is collected, filtered, stored and reused

It finishes with an Exam quick-fire facts page of the points most likely to come up in the assessment, for last-minute revision.

It’s an A4 PDF, ready to print or read on screen.
