Also commented out the retrieval of historical EIA data, as per issue #253. This was just used for validation plots

I'm curious- does this fix lead to higher or lower coal prices?

Yeah, good point. Havent compared yet, as this was just correcting the costs coming from the API. The comparison will happen in PR #249
