Engineering lesson 22: Sustainable engineering · Set 119 · 40 questions

Engineer's tip (Reduce, reuse, recycle): Reduce = use less · reuse = use again · recycle = break down and remake. Renewable: sun, wind, water, biogas, waves. Non-renewable: coal, petrol, diesel, natural gas. Count savings with × and ÷: bags per week × weeks, bottles ÷ bottles per bench.
