The energy you never use
- Every unit of energy has a cost — fuel, money, pollution.
- The cheapest, cleanest unit is the one you never have to make.
- Energy conservation 能源节约 means using less to do the same things.
- It is the fastest way to cut pollution and bills.
你从不使用的能量
- 每一份能量都有代价——燃料、金钱、污染。
- 最便宜、最干净的一份是你根本不必制造的那份。
- 能源节约(energy conservation)意味着用更少的能量做同样的事。
- 它是削减污染和账单最快的方法。
Efficiency: more from less
- Efficiency 效率 means getting the same result with less energy.
- An LED bulb gives the same light using a fraction of the power.
- An efficient fridge or car does its job on far less fuel.
- Efficiency saves energy without giving anything up.
效率:用更少得到更多
- 效率(efficiency)意味着用更少的能量得到同样的结果。
- 一个LED灯泡用一小部分的电给出同样的光。
- 一台高效的冰箱或汽车用少得多的燃料完成它的工作。
- 效率不用放弃任何东西就节约能量。
Energy conservation · 能量守恒 means… · 能源节约意味着……
Energy conservation · 能量守恒 is cutting waste — using less energy to get the same result. · 能源节约是削减浪费——用更少的能量得到同样的结果。
Conservation: cutting waste
- Insulation 隔热材料 in walls and roofs stops heat leaking out.
- Turning off lights and unplugging idle devices saves power.
- Taking the bus, cycling, or walking cuts transport fuel.
- Small daily habits add up across millions of people.
节约:削减浪费
- 墙和屋顶里的隔热材料(insulation)阻止热量漏出。
- 关灯和拔掉闲置设备的插头节约电。
- 乘公交车、骑自行车或步行削减运输燃料。
- 小的日常习惯在数百万人身上累积起来。
Saves energy or wastes energy? · 节约能源还是浪费能源?
Sort each everyday action by whether it saves or wastes energy. · 按照每个日常行为是节约还是浪费能源,给它们分类。
An LED bulb is more energy-efficient than an old bulb because it… · 一个LED灯泡比旧灯泡更节能,因为它……
Efficiency · 效率 means getting the same job done with less energy — an LED wastes far less as heat. · 效率意味着用更少的能量完成同样的工作——LED以热量的形式浪费得少得多。
Adding ____ to walls and roofs keeps heat from leaking out, saving energy. · 给墙和屋顶加____防止热量漏出,节约能源。
Insulation slows heat loss, so a building needs far less energy to stay warm. · 隔热材料减缓热量损失,所以一座建筑保持温暖需要少得多的能量。
Why it matters
- Saved energy needs no fuel and makes no pollution.
- It eases the strain on limited resources.
- It cuts CO2 without building a single new power plant.
- So conservation is a powerful, cheap climate tool.
为什么它重要
- 节约的能量不需要燃料,也不产生污染。
- 它缓解对有限资源的压力。
- 它削减CO2而不建一座新的发电厂。
- 所以节约是一个强大、便宜的气候工具。
The cleanest, cheapest unit of energy is the one you never have to make. · 最干净、最便宜的一份能量是你根本不必制造的那份。
Energy saved needs no fuel and makes no pollution — conservation is the cheapest "source" of all. · 节约的能量不需要燃料,也不产生污染——节约是所有"来源"中最便宜的。
Select all · 所有 ways to conserve energy. · 选出所有节约能源的方法。
Insulation, efficient lighting, and public transport all cut energy use. Leaving appliances on wastes it. · 隔热、高效照明和公共交通都削减能源使用。让电器开着浪费它。
Two related ideas, kept clear: efficiency is a technology fix — a better bulb or engine that does the same job on less energy. Conservation is a behaviour fix — simply using less (switching off, insulating, driving less). You need both, and together they are often cheaper than building new supply.
两个相关的概念,分清楚:效率是技术方案——一个更好的灯泡或引擎,用更少的能量做同样的工作。节约是行为方案——只是用得更少(关掉、隔热、少开车)。你两者都需要,而它们合起来往往比建新供应更便宜。
One cold house, two fixes:
- Efficiency: swap the old boiler and bulbs for modern efficient ones — same warmth and light, much less energy.
- Conservation: add insulation, close the curtains at night, and turn the heat down a little when out.
- Together the family's energy bill and carbon footprint fall sharply, with no new power station needed anywhere.
一座寒冷的房子,两个方案:
- 效率:把旧锅炉和灯泡换成现代高效的——同样的温暖和光,能量少得多。
- 节约:加隔热材料、夜间拉上窗帘、外出时把暖气调低一点。
- 合起来,这家人的能源账单和碳足迹大幅下降,任何地方都不需要新的发电站。
Energy conservation means using less energy to do the same things — the cheapest, cleanest "source" of all. Efficiency gets the same result with less energy (LED bulbs, efficient engines); conservation cuts waste through insulation, switching off, and choosing transport wisely. Saved energy needs no fuel and makes no pollution.
能源节约意味着用更少的能量做同样的事——所有"来源"中最便宜、最干净的。效率用更少的能量得到同样的结果(LED灯泡、高效引擎);节约通过隔热材料、关掉设备和明智地选择交通来削减浪费。节约的能量不需要燃料,也不产生污染。
