It's gettin' hot in here

So, apparently we're doing some thing here at FBC to reduce costs and save money on things, or something of that nature, because I've been getting emails for a few days now about helpful ways to not spend the church's money.
Yeah.
I'm sure I was told somewhere along the line what these emails are for, but I've long since forgotten, so I won't attempt to fill in the why.
Anyway, here's the one I got today, well, synopsized.

" Today’s tip for reducing operational expenditures is to dress appropriately for the seasons and the comfort level of your work area. Keep a sweater in your office instead of adjusting the thermostat.
According to Baylor University, (for heating) you will save about 3% on your heating bill for every 1° that you lower the thermostat setting. For example, if you normally keep your thermostat set at 75° all the time, and you lower it by 3° to 72°, you will save about 9% (3x3%) on your heating bill. In other words, you will save about 9 cents for every dollar you spend on heating costs.
The opposite is true for cooling. So, adjusting your body temperature rather than the room temperature could easily allow for more money to go to missions and ministries."

Then, a bit later I received this email:

So, a 3° change in the thermostat can save us 9% in energy. If we were able to reduce energy consumption by 9% across the board, we would add an additional $18,530 to the church’s budget. No additional tithing required!

Umm, I'd love to unpack my thoughts about this, but I won't. Just know that I find it funny.
Simply funny :)
