Answer:
The coal miner symbolizes the fossil fuel energy used to create electricity to power devices.
Explanation:
From the cartoon, the man looks satisfied that he is using his device but his perception of "green energy" is wrong because he feels that it does not use paper which is an animal fossil to use his device.
However, his mobile device is plugged in and the power source comes from the efforts of a human miner, so fossil fuel is in use and not from a green source which would be powered by natural sources.
