How to SUBSTANTIALLY reduce electricity use?
I'm reposting this question from the closed thread because I think it was on topic and concerns the Lakes Region due to upcoming large rate increases.
Q: What are the biggest ways we can reduce our electricity consumption substantially? I don't think that eliminating trickle charges is going to make much of a difference if the bill doubles. My biggest dilemmas are air conditioning and dehumidifiers. I work at home and have to have a cool environment. My house is very humid in the summer. The dehumidifiers (second floor and basement) use a lot of electricity. One solution I'm considering is using only the ground floor of my house. That way I wouldn't have to use the AC upstairs at night. I could just continue cooling the downstairs, which must be more cost effective than cooling down the very hot second floor at bedtime. |

My second thought, in terms of the coolness, might be an attic fan—those are inexpensive to install and surprisingly effective and efficient. Finally, have you thought about downsizing? You've posted a lot about repairs and needing to shave costs and all these extra floors/rooms that I can't help but ask. Sent from my SM-G990U1 using Tapatalk |
My suggestions...
1. Change ALL of your lightbulbs to LED... they even make LED replacements for the halogen bulbs in track lighting...
2. Get yourself a smart thermostat... I use a NEST and it has a great ECO mode for running the AC. 3. Get rid of all the small vampires you can... any small charger is almost always using some electricity. I have my phone/watch charger on a power strip that I turn on/off as needed. Same for my laptop. They make wifi enabled AC units & dehumidifiers.... that will help save $$ too. Woodsy |
There are a few key components in any household that should be examined...
1. How old is your refrigerator and how well does it seal, when closed.... 2. If you have an electric dryer, how old is it... when shopping for new appliances look at energy star ratings. Now look at the little things: - Replacing Light bulbs wiht LEDs - make sure computer monitors are shut off when not in use - ensure lights are not being left on... There are lots of things that have been done... Over the years I have fiddled with many ideas..... the 2 key components I list above are really the two main hitters, that cost people.... |

This is a golden oldie from Mom, circa 1950
This one is so basic that you’re going to laugh……weather permitting, use the cooler morning fresh air to cool your house by opening doors and windows, then close everything up, and let your shades, blinds, other windows/ door coverings work for you, keeping out the direct rays of the sun. We did this decades ago, pre AC, and it’s an easy fix. Our air conditioning has been on only a few times when the heat has been extreme, as in last week. BTW, it’s not like living in a cave either…you adjust to suit.

I agree with the energy audit as it should give an indication of most bang for the buck on various options, and which items you can do yourself.
How do you heat water? Electric? Get a timer. Cheap and effective. |
Am I the only one on the planet without A/C in the home?
A squirrel cage floor fan in the great room and a fan over our bed keeps us comfy on the hottest days and nights. If it's 90 as we pass through Meredith, it will usually be 85 when we reach home.Always cooler by the lake |
If you have window a/c units replace them with mini splits.
If you have the type of a/c units that roll on the floor and have a large diameter hose going out the window, replace them with regular window units or better yet, mini splits. Why are the floor units bad you ask? The hose that blows all the hot air out the window is the reason why. Background: For the purpose of this explanation, think of a "coil" as something much like your car's radiator. An a/c system requires an evaporator coil and a condenser coil. The evaporator coil, which is inside the house, has a fan that blows room air across it. The evaporator coil extracts heat from the air and sends it, via refrigerant, to the condenser coil. The condenser has a fan that blows air over it releasing the heat that came from the evaporator located inside the house. In a mini split, traditional central air conditioning and even window units, the condenser is outside. That means that outside air is used to extract the heat from the condenser. So here is how the floor unit with the big hose works: The evaporator and condenser are both in the unit. Each has a fan. The evaporator fan blows air from the room over the evaporator coil and gives you nice cool air out of the front of the unit. The condenser fan blows ROOM AIR over the condenser coil extracting the heat and sending it out the window via the big hose. If you were to put your hand over that hose outside you would feel a whole lot of air moving! But where did that air come from? It was drawn into your house through any gaps around the doors, windows, cellar or worst of all... your vey hot attic! So really all the floor unit does is make the room it's in cooler at the expense of the rest of the house getting warmer. As long as it's running, warm air is migrating across the house into the room that you intend to cool. It needs to run a lot! |
An energy audit is a great idea. If you can't arrange that...
There's a doodad called Kill-A-Watt that you can plug in between something and the wall outlet. It will tell you how much electricity that thing is using. Useful for figuring out what things are costing you, and what things aren't. Some libraries have these available if you don't want to buy one. |
Nope

Following up on 8gv--the same mini splits can also provide very inexpensive heat in the winter. Your electric bill will go up, but your gas or oil bill will fall by significantly more. Mitsubishi is the best brand, you may remember a thread or two on this topic

I was even able to dictate the materials that were used, as I wanted ZERO OSB used in my home and the local builders all said no, they chose the materials, the modular builder simply quoted me the additional cost and was happy to comply! Compared the old 1970's house we tore down, the heating and cooling costs were immediately 1/2 and for a house that was double in size. So for whatever all that is worth, my modular experience using APEX was great. From a stock plan, I probably made 20+ changes to the design, moving walls, adding windows, custom features like pocket doors, and the list goes on and on and I paid not one penny for an architect, the cost to modify the floor plan/design was included. Total cost per Sq/Ft was at the time was like $80 lower than a stick builder. They are worth a look, but its not for everyone, its a whole lot more complex than just buying a house. But for those able to do it, there are big rewards at the end of the project! https://www.apexhomesofpa.com/ Best of luck! |
I knew it was going to be an issue in the spring of 2016 when we started to ship significant amounts of LNG, so I made most of the major changes.
I average about 247 kWh per month... summer and winter are a bit higher... but fall and spring tend to be lower. |

You could be right.
Well ventilated attics shouldn't need fans - which would use electricity to operate - they should draw air from either the eave vents up and out the ridge vent... or seek humidity/temp balance with the outside through the gable vents. |
John, last year we were talking about the relationship (in terms of air flow) between ridge vents, gable vents, and soffit vents. I can't remember what was said. Do you recall this conversation?
|
Yes.
Sometimes people mix the formats together and it actually diminishes the airflow. Gable Vents in general tend to create draw from soffit vents and throw off the action of the ridge vent. |
Quote:
I'm not saying they are as efficient as a good quality window unit, but they aren't awful. |
The floor models serve a different purpose.
Window units and mini-splits are stationary. Floor models were designed so that you could condition just the room you were in and move with you to another room. |

Nothing a boat load of money can't fix...

Quote:
It may be worth trying to close the gable vents off... But you would need to monitor temperature and humidity for a time to determine that the soffit-ridge combination is working as designed. If the temp or humidity rises, then something isn't right. |
I agree with John.
I have a temperature activated exhaust fan at one end of the attic, exhausting out the gable vent. Air is pulled in from the other gable end, you can feel the flow when the fan is running. I'm sure some air comes in the soffit vents as well, which is a good thing, you simply want that hot moist air replaced with not-quite-so-hot air. I really like the fan system, though per this thread that's one more electrical device. I can't see why having all your vents open is a bad thing unless air doesn't vacate one area or another due to short circuiting of flow. |
As far as attic ventilation vents go, gable end vents by themselves generally don't do what the homeowner expects. Air exchange through such vents is minimal. The best arrangement is with a ridge vent and either continuous soffit ventilation or at least vents in each soffit bay. With both ridge and soffit vents, it is generally advised to close off any gable end vents, as they interfere with draw of air in the soffit vents.
On the subject of powered attic ventilation fans, this is a good read: https://www.greenbuildingadvisor.com...tic-ventilator. In general, it isn't a good idea, and it's the wrong way to address a problem. |
Quote:
|
It is the mixture of heat/humidity relative to the ambient air outside the attic.
If the heat/humidity in the attic is much higher than the ambient, the venting system is not functioning properly. |
Quote:
As to attic temperature being much higher than ambient, "much" is relative. With the sun shining on the roof, the attic certainly will be substantially hotter than outside air. With proper soffit and ridge ventilation, it's the air density difference due to the temperature difference that drives ventilation air flow. Using a powered fan to ventilate a hot attic will reduce attic temperature somewhat, but that's a wasteful, less-effective, and sometimes counter-productive way to address the discomfort issue. Besides the direct conduction of heat through an inadequately insulated attic floor, a hot attic also enhances the "stack effect" (like the draft up a chimney produced by hot combustion gases). Without good air sealing between attic and the living space, a hot attic draws some of the air flowing out the ridge vent from the living space below, and that increases leakage of hot/humid air from outside into the living space. That, in turn, produces discomfort and increases load on an AC system. Stack effect air leakage also produces discomfort in the way of cold drafty areas, or at least higher heating bills, in winter. A good energy audit, by someone competent, is a good first start for an existing house. A blower door test with IR photography can locate sources of air leakage and even rain leaks in the roof or around windows. That's a good starting point for a thorough air sealing project, much of which can be done by the homeowner. It's the "low-hanging fruit." For a new house, it's much better to make the house well insulated, much better than "to code," and very tight, with mechanical ventilation for controllable interior air quality. Not doing so for a new house is a wasted opportunity. |
Much higher to me would be due to reduce air flow.
The much higher temperature creating the drafting effect... But registering a much higher temperature over a long period of time... including early morning hours... should be a red flag that the draft is not working. A higher than ambient humidity level over the long period also can be a red flag that the draft is not working. It can be caused by other items, but an attic fan would not be the first plan of attack... more of a band-aid covering up a bigger problem. But one item at a time needs to be addressed. If the draft is working correctly... then she can turn her attention to reducing humidity transmission from below - hence my focus on gutters. Charging unsealed foundation walls with wet soil is going to increase humidity in the interior. It is a process... but one item at a time needs to be addressed. |

LEDs emit an amount of blue light that is hard on the eyes, especially for older people with cataracts. I will check out the Phillips soft white bulbs, thanks. https://www.oledworks.com/news/blog/...ght-from-leds/ |
There is a spectrum of LED light "temperature" that is expressed with numbers.
You can compare the lights side by side and then, using the temperature number of the one you like, apply that to other lights you purchase. Some ceiling fixtures have a small switch that allows you to choose the temperature you prefer. That decision is made prior to installation but the switch position can be changed if you are willing to pull the fixture down to do so. My preference is about 3,000 to 3,500 which might be described as warm white. Up around 6,000 feels like emergency operating theatre to me. :eek: |
Maybe we should rig a stationary bike or treadmill to a generator system.

I think you've over-estimated the power draw of your router by a factor of 10. Unless the router is also serving as a hotplate there is no way it is using 120Watts.
|
Quote:
If I'm reading it right it says 1 amp, which would be 120 watts? |
Quote:
It's 1A at the 12VDC output from the power supply, so 12 watts. And even that is more likely a peak value and not a constant value, realistically the average power consumption of it is likely under 10 watts. Your calculation then was essentially a yearly operating cost, not a monthly one. |
I guess I must be in the minority. Yes I am concerned about the rate hikes but am not obsessing about it to the point I am concerned with how much my router draws. :laugh:
We are finishing up a reno and moving to Gilford. Our "new to us" home will have all led lighting and Samsung split systems with LP boiler backup (hot water off the boiler). We also have 2 pellet stoves, 2 fireplaces and are looking at putting in between 50-80 400W solar panels which should offset our entire usage. We have a huge roof system with multiple planes, so covering them in solar will help. We run our AC hard in the summer. I am a big guy and like to be cool. Our electric bill in our existing, newer home that we are leaving runs between $300-$450 depending on the season. That is with NG heat/hw, 2 mini splits, a hot tub and every light in the place always on. We do a ton of laundry, unless we are at the lake there is laundry running every day with 5 of us in the home. |

I would still like to know how to estimate my new monthly Eversource cost for the top items on my list. If I know the kWh per month of an appliance, how can I calculate the cost?
|
Quote:
For example, if you estimate 400 KwH of electricity usage in a month, and your fully-loaded KwH supply charge comes out to $0.22 per Kwh then your estimated bill would be 400 * $0.22 = $88. Conversely, if you eliminate 10 KwH of usage through various reductions, then you can estimate the savings the same way, 10 * $0.22 = $2.20 in savings. |

Some of the fees are not increasing, just the supply rate. It sounds like the net effect will be about a 50% increase in your overall utility bill for an average user. |
Quote:
For someone using 450kwh/mth., the bill would go up ~$52. If I didn't change to a new supplier, my highest bill last year would have been something like $250 more. With the new supplier, that will be more like $100 more, which is better than the alternative but still blows. Sent from my SM-G990U1 using Tapatalk |

We're in a 2100 ft² split built in the late 1970's. Central air, dehumidifier, electric stove, electric dryer, etc. AC set at 72° for all but while away, which was 75° and water heater set to 120°. The three things I'm currently trying (as I type this by the lake): dehumidifier set to 60 instead of ~45, water heater set to vacation mode while away, AC set to 85 while away. The killer for us is electric baseboard, but we've never changed for a ton of reasons. Though I think we can minimize/negate the price increases, I may look more into heating this next year.

Think, that's interesting, thanks for the comparison. My house is something like 1400 square feet and I'm one person so I should be doing a lot better than you. BUT (confession) I set the AC to 64 so it's basically running all the time. On the other hand, in the winter I set the boiler to 60.
I think 60% could be OK for your humidity. It's not radically over the normal 50%. If you have time maybe you can PM me about changing your electric supplier. |
Quote:
In terms of changing suppliers, I signed up with Direct Energy yesterday for $.16/kWh which will cut the increase in half. I researched a bunch of suppliers and they were the best price—I did see in a place or two that customer service might not be perfect, but I'm not sure what that means in this case as, supposedly, I'll still work directly through Eversource. I signed for 36 months, but the current offers don't have early cancellation limitations. Sent from my SM-G990U1 using Tapatalk |

Add a fan
SailinAway, my sister in law lived in FL for several years. She kept the AC at 76-78° but would drop it down to around 70. We went shopping once day and I bought her an oscillating fan on a stand. Used it on low only thermostat back up to 75 or so. Fan moved the air around and the AC took ot most of the humidity.
No AC at my house now. If it's humid, I put my fan in the opening on low at night and usually manage to get a good night's sleep. Keep the AC set high and just use a fan to move the air. Dave PS Wintertime: sweaters/ swearshirts and a lap blanket help with the heat. |

Exhaust fan
Our camp has no AC and no insulation, so on hot days the temperature is the same inside and out. We have a large window fan installed in the living room. At night, I close all the windows except the one in the bedroom and in the bathroom and set the window fan on exhaust. It pulls a nice breeze through the cottage. Even when it was 90+ during the day, I was able to sleep with a light blanket at night. I'm the type who keeps the house at 65 during the day in winter and 60 at night, so I am not a fan of super hot weather. The exhaust fan works! I believe we ordered it from Sears. It fits the lower sash of our front window.

My remarks were made assuming you have a central air system.
Portable window and floor units have filters that need periodic cleaning. |
Update: after 4 days away, we came back and, set at 60% humidity, the basement smelled a tad musty. I've moved it to 50, so we'll see what happens there. Maybe the sensor isn't so inaccurate after all.
We had turned the AC up to 85, which actually wasn't terrible in the house since the humidity had still been removed. It did take a while to cool down to 75, though, so I'm wondering how long it has to be set at 85 to save money when "catching up" on our return home. I have to think having it set at 85 for the days it was 95+ saved us a few bucks. I've got the AC set to 74 right now—we tried 75, but that was just a tad warm. 72 was cool enough to need blankets, so I'm thinking 74 will be fine and save us some moolah. I wish I could have tested the water heater temp when we returned (after putting it on vacation mode). The tank, 50 gallons, is in a well-insulated closet, so I don't think there's much standby loss at all. I did turn on "energy saver" mode, though, which is supposed to tailor itself to our water use habits. The last thing I've been thinking about is the dryer and cooking. We can easily do more grilling and use smaller burners when cooking, but I don't see much of an alternative to drying clothes—given its location, it would be a pain to hang outside and hanging inside would increase humidity that the dehumidifier would have to pull out...though now that I think about it, my washer has an extra spin mode that might help. It's a Speed Queen, which is so powerful it'll spin those things almost dry on its own. To the basement! Sent from my SM-G990U1 using Tapatalk |

Think, sorry you've fallen on hard times and have to count pennies like this. ;-(
An alternative for the dryer is to dry your clothes outdoors until they're almost dry and finish them in the dryer for 10 minutes. That will soften them and take out the wrinkles. It's definitely labor intensive. In the winter you can do the same but indoors, which will add needed humidity but be labor intensive and not improve your interior decoration. For the AC, why blankets? Use a sheet and a fan and turn up the AC a few more degrees. Don't forget to recycle the water from the dehumidifier while you're on this conservation kick. My basement is very humid and I'm finding it does not need to be dehumidified every day. Maybe once or twice a week. Open the basement door on the rare dry day. |

FREE Hot Water
Years ago my father in law had a cabin on a lake in Maine and routinely had free hot water May 15th thru October 15th.
How? He had about 1,000 feet of hose in his attic and used that as his source of hot water every season. Seemed to work very well for him as that attic hose would heat the water very well during those sunny days. Rarely ever ran out of it...... Now if you had a week of cold rainy days then it definitely wouldn't work as well. |

Update: reduced my electricity use by 67%!
I just got my Eversource bill. Compared to September last year, I've reduced my electricity usage by 67%! The bill was $76 for 199 kWh. The August bill was $134 for 454 kWh. This is before I switched to Direct Energy as my cheaper supplier, which should be reflected in my next bill.
In August I (like many Americans and especially here in New Hampshire) suddenly became aware of the full meaning of inflation and I brainstormed and studied all the ways I could find to reduce expenses with electricity, telephone, internet, gasoline, heat, water, and home maintenance. I calculated the kWh of each electrical appliance in my home. I tracked my money-saving actions each day, which added up to 48 actions in one month. A sample:
I still have quite a few things left to do, like finding the best way to get hot water for the shower, changing my Medicare advantage plan, and finding someone to split a recalcitrant maple tree. I realized that I was living as if I had unlimited cheap resources, with no real mindfulness about how much I was using, even though I'm normally frugal. That's not wise environmentally or financially. Simply becoming more aware of what I'm using and how much it costs has made a big difference in my expenses. Utility companies make if so difficult to reduce costs that probably most of us can't face the amount of time it takes to do the research and negotiate with the companies. By the way, thanks a million to Thinkxingu for doing the research on energy suppliers and sending me to Direct Energy. It sure feels good to be depriving Eversource and Consolidated of their exorbitant increases. |

Why?
Are certain candidates in a position of authority going to go to price caps? If not, CAPITALISM rules supreme. We make more money in Europe on Natural Gas... so it isn't going to get cheaper here. |

We are sending more LNG to Europe from a 2018 EO... so natural gas prices are up for electricity... not to mention the local infrastructure was not designed for the higher level of demand from all the new building in the State. We went from 13M b/d of refining capacity to 12M b/d between 2016 and 2020... that isn't coming back and more refiners are scheduled to close because investors consider prices to be too low. So all that leaves is coal, that has to be brought in by rail... not a federal issue... and I haven't seen a lot of interest at the local level to redevelop the rail lines for year round freight use. The secret... learn to be an actual conservative and conserve. Those of us that do... we don't even feel any of the present pain that the rest of you seem to be moaning about. |

Demand has a direct influence on the basics. The 2018 EO allowing more LNG to be sent to Europe was capitalism as it normally works. The shutdown of the 1M b/d of crude refining is capitalism as it normally works. The scheduled shutdown of the Houston refinery at the end of 2023 will also be capitalism as it normally works. A price cap... or a price support... that would not be capitalism as it normally works. Releasing the SPOR was an attempt to avert capitalism... it might be working... but it will only be for a short period of time before it can no longer do so. The industry has stated we need demand destruction to bring the balance back into line... so far... people have just been working on substitution. Can't get gasoline... go to electricity... but then the grid can't handle the demand. Europe is only going to reduce demand so much... and as long as they are willing to pay more for the energy than Americans, we will ship it there until we run out of ships. I would hate to see this generation to have to deal with the war rationing that our Greatest Generation did. |
John, I am talking in general not specifically regarding fuel. Hope that helps.

Well said JM. A lot of people would like to believe it is politics that cause high prices but forget that business is world wide. Just like they want wage increases but don’t expect consumer prices to go up when people are paid more.

Back to the topic at hand--as Sailin and John have pointed out--it's easy to reduce your utility bill without too much pain, and the implications of doing so are great all around. I'll also add that investments in insulation, solar, heat pumps, etc are a whole lot cheaper with the recent passage of the Inflation Reduction Act. Check details with your installer if you're considering these things |
