which found JPEG decoding to be much less energy intensive than PNG decoding, mostly because it's faster. Note that that's not just a function of file size, as lower quality JPEGs actually took more energy to decode.
Which all makes a lot of sense when you consider how much work has gone into optimizing frequency domain based compression and decompression.
