Our parish's monthly utility bills usually total at least $4,000, as you can see by clicking on this graph of utility costs over the last two years. Winter heating bills and summer cooling bills always push up our utility costs. A less obvious expense is the cost of the electricity we use to run our pumps to keep the water out of the church basement. (Did you know that our church sits over an underground river, which has led to a flooded church basement more than once?) The cost of this pumping is probably a large contributor to our church electricity bill, which generally exceeds $2,000 per month.

November and December are sweet spots for utility bills: between the extra high electric bills of summer and the extra high gas bills of winter.  So, our November and December bills (for October and November usage) were "only" $3,762 and $3,622, respectively. January saw an upswing in our total utility bills, reflecting the colder weather of December. As shown in our gas consumption graph (below), December 2016 was colder than December 2015, and this is reflected in the higher utility bills for January 2017.

We're working to reduce our utility costs--in part to save money and in part to avoid undue harm to God's creation.  In January 2014 we used funds from the Capital Stewardship Campaign to replace a failed HVAC control system with a modern system that allows us to better control our heating and cooling in the basement and gathering space.  (Controls for the sanctuary were replaced a few years before that.) We also have energy-efficient lights in many places, and in the summer and fall of 2015 we upgraded our outdoor lights. At some point we will replace our church boiler, but we can't justify the large capital cost yet. Meanwhile, the boiler in the office died in November 2016, and the replacement is a high-efficiency model, so we'll see a decline in gas consumption from that incident.

To see how much gas our church and office buildings have been consuming, click on Church and Office Gas Consumption.  Notice that our gas consumption is highly dependent on the weather.  One can see this by noticing the strikingly seasonal pattern of the consumption graphs or--in more detail--by comparing gas consumption to heating degrees/days.  Gas consumption should track heating degree days closely, though other factors such as how much the building is used (and hence needs to be heated to a comfortable temperature) also influence consumption. Thankfully, this past winter was more mild than the previous two winters.
