## Tools (3)

- `estimate_heating_fuel_cost`: Cost of a heating oil or propane delivery (gallons times this week's EIA average for the state, or a given price), the cost per million Btu, and a comparison of heating oil and propane per million Btu at the same area's averages. Optionally add your electricity rate (cents per kWh) or natural gas rate (dollars per therm) to compare. Uses EIA heat contents.
- `get_heating_fuel_price_history`: EIA weekly residential heating oil or propane prices per gallon for the US or a surveyed state between two dates (series since 1990 for most areas), with high, low and average. Default is the last 52 weeks.
- `get_heating_oil_propane_prices`: Latest EIA weekly average residential price per gallon (taxes included) of heating oil and propane for the US, an EIA region or a surveyed state, read at call time from eia.gov: price, change from last week, the last five survey weeks, the price a year ago and the next release date. Heating oil is surveyed in Northeast and Midwest states; propane in about 40 states. Uncovered states return the covered list.
