Heating oil

Datasets and utility bills sources and reliability:

Annual heating oil data is 100% accurate for delivery records. Daily use is from gauges on the oil tank and is not as reliable. It is pretty good if averaged over about 5 days.

Electricity data is from Eversource bills and an Efergy whole house meter. It is 100% accurate.

Solar power data is from the Solar Edge reporting system and has been audited to the net-metering credits on my Eversource bills
