The 2010 SIREN Energy Showdown SIREN's Energy Showdown contest awarded prizes to participants who achieved the greatest percentage reduction in their electricity bills. Collectively, more than 11.5 Megawatt Hours of electricity were saved by the Energy Showdown contestants.

PRIZE WINNERS:
Woodie & Pam Bessler Pam and Woodie won our second quarter prize as well as our grand prize, a 1kW PV solar system. Read Woodie's comments below and watch for the article in the Down to Earth section of the Herald Times.
To begin with, our philosophy for the contest was doing stuff that could allow us to make permanent reductions in our net energy, and not just a shift from one type to another, or a temporary "suffer through" improvement. On the other hand, my wife had expressed concern about her and the children "FREEZING in the DARK", so I also set out to make fundamental changes that would still be acceptable/tolerable (to avoid a mutiny). Focusing on WASTE was my first plan, since it is the least painful usage to give up.
Long before the contest we have been trying to reduce our utility/energy use (Gas, Electric, Water, Gasoline) by using energy efficient CFL's, front-loading energy efficient washer and dryer, not leaving appliances on when not in use, etc. As a continuation of that, near the middle of 2009 we replaced the fridge that came with the house with a new Energy Star model. Overall we use only about 66% of the electricity used by the typical Indiana home, so when the contest opportunity came along, we weren't sure we could do enough to compete, but the contest fostered some new ideas.
Before the contest started we (I) began prepping the family by warning about how "Things are going to be different next month!". After Jan. 1, I began nagging about lights being left on and how "if you're not in a room, the power and lights must be off". Not always effective with 7 year-olds. So then I tried putting in some LED lights that were even lower consumption than the CFL's. I also installed some cut-off-switches that automatically shut off unattended loads. These are especially great for bathroom fans and hall lights. I separated four bathroom lights that had been all on one switch into two switches, so when you didn't need the extra light, you could turn on only one. All these things helped cut down on the amount of lights left on by the twins. I started showering only with "day-lighting" to eliminate the lights at that time. I cleaned the coils of the Refrigerator and changed out the Furnace filter. We have also used a Kill-A-Watt meter to see where we were using our electricity. This data allowed us to prioritize changes. I was surprised to find out how much energy gets wasted by the phantom power drawn by things that use power even when you think they are off. Based on this we started unplugging or using power-strips, etc. to reduce these loads. After about 20% reductions in Jan. and Feb. I was encouraged, but was not doing as well as I had wanted to. More digging revealed that our furnace fan alone draws about 450 watts, so I installed an old "green plug" device to help reduce the fan draw (we had used it years ago with an old style refrigerator with good success). As Spring began we were bouncing between heating at night and even some cooling in the day, so I revised the programmable thermostat to try to avoid these spikes, and instead get more passive heat with sunlight through windows during the day and free cooling with open windows at night. We got to 40% in March. In the Spring, the cooler weather helped us too. We could use fans instead of A/C until the humidity got too high. Then to get the most from our cooling system we had the Central A/C tuned up, and began using a window unit when we could -to do some zoned cooling. We had done this last year too in the largest room in the house with some success. For the last couple of years we have used a dehumidifier too, because warmer air can still be more comfortable when it has lower humidity, and the dehumidifier uses less energy than the central A/C. Another thing that helped us this year was fixing the downspouts last Fall, to send the rain water farther from the house, so it wouldn't get pumped out by the sump-pump, or accumulate in the crawl space and add to the house humidity. Before we opened our pool for the year, we substantially cut back on the need to pump off the Spring rains that accumulate on the pool-cover by instead starting a syphoning action rather than the way we use to do it with a 360 watt pump! I also built a custom, pool-filter-pump-timer to duty-cycle the 220V pump filter to reduce it's net consumption. We also changed out the pool filter to make sure it is working with less back-pressure (load). The pool has the advantage of providing an alternative to using A/C to cool off with too.
Other thoughts we've had, we are still cooking with an electric range (and my wife actually would prefer gas), but I'm not really sure if it will make much difference, and getting a gas line installed might take too much money and time away from sealing leaks in the attic and crawl-space. I'm hoping the Blue-line Power Cost Monitor might give me a way to see if the stove change would actually make a difference. I also bought a Solar Oven at MREA, that may also cut down on our cooking-electricity usage.
To boil it down to a few
"tips", I would say:
1.) Look for and eliminate
waste first (least painful).
2.) Improve efficiency
(lighting, appliances, etc.)
3.) Figure out new ways to
get an acceptable outcome with less energy (like the
syphoning example above, or air-drying your clothes).
4.) Make A/C cooling more
efficient by reducing humidity with a smaller auxiliary
unit.

Read Meagan's post here to learn the secrets to her success. Last year, we participated in the Southern Indiana
Renewable Energy Network's (SIREN) Energy Challenge. The goal
was to reduce electric energy usage.
________________________________________________________________________________ Q3 and Q4 Winners: William Emigh and Maggie Sullivan Will and Maggie were able to make some very impressive reductions, even though they had already reduced their energy consumption well below that of the average household. Here are a few of their secrets. Will's response: Honorable Mention:
Lisa Thomassen and Family We've managed our reductions without buying any new appliances. So we still have our 12 year old refrigerator (we clean the coils regularly), our 12 year old TVs and computers, and so forth. We've purchased compact fluorescent light bulbs, but that's it -- no fancy appliances or meters for us. We don't drive a new Prius. Instead we have a '79 Hondamatic civic. It's actually green. ________________________________________________________________________________ For more great energy-saving tips, check out the Green America website and fore even more detailed tips, check out the Coop America Newsletter. ________________________________________________________________________________
