Educate me on How much a "W" costs p/kwh
When comparing cost savings in lighting.... I'm trying to convert the advertised #W to find how much it will actually cost on my electric bill charged by the kwh which for me is .0879 per kwh...
I'm probably wrong in the way I'm guestimating this. I'm trying to determine the difference between running a small 96w t5 as a supplement v. running a 120w led fixture at most likely only 75% anyway. But I really want to know how to make this conversion so I'm sure someone knows...

$.0879 x 96 watts x 8hrs/day x 30 days/month=2025.216/1000=$2.02/month.

Make sure you look at your bill because a lot of people in the USA are on the Tiered rate plan.
For say 0-400kwh you pay 8-9 cents /kwh 400-600 12-14 cents Just look at your bill and you will understand. The way it works is the more energy you use the more you spend. So in summer months if you use a chiller and your house is running the AC. You are essentially paying double, triple, or more. I've seen people in tier 4 and 5 paying 32-40 cents per kwh. At that rate running 100w 8 hours a day will cost you approx. $.36 (average) x 100 watts x 8 hrs/day x 30 days/month = 8460/100 = $8.46 / month for every 100w. So while $2.02 is alright, if you don't know how the tiered rate works, you could be paying $8.46 a month for those same 100w. |

If you have questions, PM me or post here. Or better yet, post a copy of your bill with all the personal information blackened out. But usually the tiered rate information is on the back. A lot of people misunderstand what SOLAR are supposed to do as well. The purpose of solar is not to produce 100% or more than 100% of your energy consumption. The goal is to reduce the amount of times you go into tier 2, 3, and higher. By doing this, you are saving money. If you are "farming" energy with solar you are doing it wrong because the amount the energy company pays you for the energy is minute compared to how much you pay for the energy.

In CT the plans are not tiered. I don't think most of new england is either, but good info to some none the less.
