> if you want to know quantities emitted currently and up to now, your graph was great. No, my graph would not be very useful for that. For that, you'd want the area under those curves, i.e. the sum of all historical emissions. My curve is just showing how much electricity in a given year is produced by which source. Total energy usage in China is growing very fast, and Coal is a big part of that. > But I didn't ask about that, I asked about the trend, so in fact you replied to me with a misrepresentation. No actually, the trend is that China's usage of coal is widespread and growing very fast. Showing that the percentage of coal in their electricity mix is stable or shrinking only shows that the *acceleration* of coal usage in China is stable or negative, even if the trend is increasing usage.
