空调 26℃ 比 22℃ 能省多少电、减多少碳？
How much power and carbon does 26°C save versus 22°C on AC?
每调高 1℃ 约可省 7%–10% 的制冷电耗；从 22℃ 提到 26℃ 约省三成电，既舒服又明显减碳，还能缓减电网高峰压力。
Each degree higher saves roughly 7%–10% of cooling power; from 22°C to 26°C cuts about a third of the electricity—comfortable, lower carbon and easier on the grid peak.

选购家电看“能效标识”一级和三级，长期电费差多少？
Buying appliances, how much do tier-1 vs tier-3 energy labels differ in long-run electricity cost?
一级比三级通常省电 10%–30%，对冰箱、空调这种长年开机的大户，几年累计的电费差额常能抵回稍高的购机价，是全生命周期最划算的“隐性强减排”。
Tier-1 usually saves 10%–30% versus tier-3; for always-on fridges and AC, a few years of saved bills often repay the slightly higher price—a 'hidden, high-value' cut over the product's life.

家里最耗电的电器通常是哪些，怎么省？
Which home appliances usually use the most electricity, and how to save?
空调、电热水器、冰箱、洗衣机往往是用电大户。善用节能模式、夏季空调调高几度、热水器随用随开、冰箱不塞太满，能明显降电费。
AC, water heaters, fridges and washers are usually the biggest users. Eco modes, a few degrees higher AC in summer, on-demand heating and not overpacking the fridge cut bills noticeably.

洗衣机能效和“冷水洗”对减碳的帮助？
How much do washer efficiency and 'cold wash' help cut carbon?
加热水是洗衣耗电大头，用冷水洗可省下约 80% 的洗衣能耗；选高能效机型、攒满再洗、自然晾干，能进一步压低碳足迹。
Heating water is most of a wash's power; cold washing can cut about 80% of that energy. Efficient models, full loads and air-drying lower the footprint further.

“待机能耗”是什么，为什么拔插头能省电？
What is 'standby power', and why does unplugging help?
电视、机顶盒、充电器关机后仍偷偷耗电，叫做“吸血鬼负载”。用带开关的插线板一键断电，长年累月能省下可观的电与碳。
TVs, set-top boxes and chargers still draw power when off—the 'vampire load'. A switched power strip cuts it all at once, saving real energy and carbon over time.

随手关灯省的是发电厂的煤吗，为什么？
Does turning off lights save the power plant's coal, and why?
用电少，电厂就少烧煤少排碳。每盏灯看着小，全校、全城一起关，累计起来就是实打实的能源和蓝天。
Less electricity means the plant burns less coal and emits less carbon. One bulb is tiny, but a whole school or city switching off adds up to real energy and cleaner air.
