@PotatoClose @PSQ17266 @Kit_Yates_Maths Also the 500 KWh/y estimate on that site is very wrong for a classroom. Maybe reasonable for 24/7 operation but classroom time is about 1000 h/year, so actual KWh is more like 50 KWh. Electricity is about 0.2 Kg CO2 per KWh. Again, this just isn't significant. Stop trolling.
@PotatoClose @PSQ17266 @Kit_Yates_Maths 此外，该站点上 500 KWh/y 的估计对于教室来说是非常错误的。 24/7 运行可能是合理的，但课堂时间约为 1000 小时/年，因此实际千瓦时更像是 50 千瓦时。电力约为每千瓦时 0.2 公斤二氧化碳。同样，这并不重要。停止拖钓。
