Microwave vs. Stove - which one is more energy efficient?

energy efficient microwaveYour microwave is a much more efficient way to heat or reheat than your stove top, mainly because your stovetop wastes quite a fair amount of heat. Your microwave uses about 80 percent less energy than your stove for heating up relatively small amounts of food. 

Even though your microwave uses a lot of electricity, it’s a small burst of power vs. the long, delayed energy used to heat up your stove. Of course, you can save some of the energy you’re using on your stove by using pots that are size appropriate to the burner. The EPA warns that using a six inch pot on an eight inch burner can waste the majority of the burner’s heat.

You can heat up a cup of ice cold water to boiling in an 800-watt microwave in 2.5 minutes. To find out how much energy that would take, you calculate the amount of electricity used in kilowatt hours (kWh) by taking the device’s wattage and multiplying it by the time. So 2.5 minutes = 0.042 hours, and 800 watts is .8 kW. Multiplying kWh capacity by time, we get .8(0.042) = .034 kWh to heat the cup of water.

So, when you want a great reason to do dinner the easy way and need some scientific numbers to back it up, refer back to this blog and pop that plate in the microwave - to save money of course.

Getting smart about Christmas lights in 2018.

Tuesday, November 20, 2018

Halloween came and went, and now, it's beginning to look a lot like Christmas! Well, once the decorating is finished, that is. One of the most visually pleasing parts of the season is all the festive lights in creative places on neighboring houses. But that type of effect isn't limited to just outdoors; lighting plays a big part in Christmas inside as well. A tree with no lights looks dimly like a big plant in the center of the room. That's until the carefully strung lights shine throughout the magnificent green (and sometimes even white) tree and show off what's adorned on the branches. To make sure you get the most of your festive lighting, this year make a switch if you haven't already too smart lighting with LEDs.

Thanks for Saving Me!

John's Electric was wonderful! I called and he was at my house within an hour!! I was at great risk of fire because of my breaker overheating, and he got me taken care of quickly, and affordably! I have a home warranty, that wouldn't cover my issue, and he jumped in and took care of me. If I ever had need again, I know who to call. Couldn't recommend John's any higher!!!
