00:00:01,800 --> 00:00:06,960
Speaker 1: Welcome to brain Stuff, a production of iHeart Radio, Hey

2
00:00:07,040 --> 00:00:11,799
Speaker 1: brain Stuff, Lauren Boobam. Here. In these times of ridiculous

3
00:00:11,800 --> 00:00:15,440
Speaker 1: inflation and over the top gas prices, many consumers are

4
00:00:15,560 --> 00:00:17,599
Speaker 1: looking to save a buck or two wherever they can.

5
00:00:18,560 --> 00:00:21,480
Speaker 1: Of course, energy costs money, and the more you use,

6
00:00:21,600 --> 00:00:24,640
Speaker 1: the higher the bill is going to be. And air

7
00:00:24,680 --> 00:00:28,600
Speaker 1: conditioners account for six percent of US electricity costs per year,

8
00:00:28,800 --> 00:00:31,639
Speaker 1: which is about twenty nine billion dollars according to the U.

9
00:00:31,720 --> 00:00:35,279
Speaker 1: S Department of Energy. We know that running the air

10
00:00:35,320 --> 00:00:38,519
Speaker 1: conditioning unit all the time is expensive, But will you

11
00:00:38,640 --> 00:00:41,080
Speaker 1: save money and energy by keeping it at the same

12
00:00:41,120 --> 00:00:44,919
Speaker 1: temperature continuously or by raising it higher when you're out

13
00:00:44,920 --> 00:00:49,000
Speaker 1: of the house. A lot depends on how long you'll

14
00:00:49,000 --> 00:00:52,400
Speaker 1: be gone, like don't turn off the unit entirely if

15
00:00:52,400 --> 00:00:56,480
Speaker 1: you're just going to work. For the article, this episode

16
00:00:56,480 --> 00:00:58,680
Speaker 1: is based on how Stuff Works, spoken by email with

17
00:00:58,760 --> 00:01:03,560
Speaker 1: Logan Cresca, communications consultant at Duke Energy in North Carolina.

18
00:01:03,840 --> 00:01:06,160
Speaker 1: She said, if you're just leaving home for the day,

19
00:01:06,280 --> 00:01:09,240
Speaker 1: it's more energy efficient to keep your air conditioning turned on,

20
00:01:09,760 --> 00:01:11,959
Speaker 1: but turn it a few degrees higher than you might

21
00:01:12,000 --> 00:01:15,360
Speaker 1: set it for comfort if you were at home. The

22
00:01:15,400 --> 00:01:17,480
Speaker 1: same directions apply if the house is going to be

23
00:01:17,560 --> 00:01:20,800
Speaker 1: unoccupied for only a day or two. Turning off the

24
00:01:20,840 --> 00:01:23,720
Speaker 1: A C unit during the day isn't necessarily a bad thing.

25
00:01:24,240 --> 00:01:26,679
Speaker 1: It would just have to stay on longer to cool

26
00:01:26,720 --> 00:01:30,200
Speaker 1: off a hot dwelling. In fact, the unit may use

27
00:01:30,280 --> 00:01:32,520
Speaker 1: more energy if it's left on all day at the

28
00:01:32,520 --> 00:01:34,520
Speaker 1: normal coolness than if you turned it off for the

29
00:01:34,600 --> 00:01:39,120
Speaker 1: day and back on again in the evening. That said,

30
00:01:39,240 --> 00:01:41,520
Speaker 1: if you live in a hot climate, it could take

31
00:01:41,600 --> 00:01:44,640
Speaker 1: several hours to cool off your house, which would be

32
00:01:44,640 --> 00:01:49,280
Speaker 1: pretty uncomfortable. Also, central air conditioning isn't just about cooling

33
00:01:49,320 --> 00:01:53,800
Speaker 1: your space. It also drastically reduces humidity levels. When the

34
00:01:53,840 --> 00:01:55,840
Speaker 1: system is shut off for more than a few hours,

35
00:01:55,880 --> 00:01:58,760
Speaker 1: the humidity level will start to rise, which can result

36
00:01:58,800 --> 00:02:02,240
Speaker 1: in mold growth. Much to electronic items and the warping

37
00:02:02,280 --> 00:02:05,440
Speaker 1: of wooden paper. Any pets left in the house could

38
00:02:05,440 --> 00:02:09,280
Speaker 1: be at risk of discomfort or overheating. This is especially

39
00:02:09,320 --> 00:02:14,040
Speaker 1: likely in hot human climates, but like Florida. This is

40
00:02:14,040 --> 00:02:16,720
Speaker 1: why it's recommended to keep the A C on, but

41
00:02:16,960 --> 00:02:20,400
Speaker 1: raised to a higher temperature. The Department of Energy points

42
00:02:20,400 --> 00:02:23,919
Speaker 1: out that a higher interior temperature actually slows the flow

43
00:02:23,960 --> 00:02:27,160
Speaker 1: of heat into your house, thus saving energy and money

44
00:02:29,120 --> 00:02:31,640
Speaker 1: either way. When you get back home, don't turn the

45
00:02:31,639 --> 00:02:34,880
Speaker 1: A C super low to speed up the cooling process.

46
00:02:35,360 --> 00:02:38,600
Speaker 1: Your home won't cool any faster. The unit only works

47
00:02:38,600 --> 00:02:41,360
Speaker 1: at one speed. You'll just be adding to your energy bill.

48
00:02:43,400 --> 00:02:47,160
Speaker 1: If the entire household pets included, are vacating the premises

49
00:02:47,200 --> 00:02:49,480
Speaker 1: for more than two days, it is an option to

50
00:02:49,520 --> 00:02:52,480
Speaker 1: go ahead and turn everything off. You'll certainly save the

51
00:02:52,520 --> 00:02:56,240
Speaker 1: most energy and money on your bill that way. That said,

52
00:02:56,520 --> 00:02:59,360
Speaker 1: the internal temperature might not be pretty when you get back.

53
00:03:00,080 --> 00:03:02,520
Speaker 1: You can avoid coming home to a sweltering abode by

54
00:03:02,520 --> 00:03:08,400
Speaker 1: installing a smart thermostat. Kriska explained investing in a programmable

55
00:03:08,520 --> 00:03:11,040
Speaker 1: or smart thermostat is a great way to monitor and

56
00:03:11,080 --> 00:03:14,000
Speaker 1: control your home's energy efficiency even when you're not there.

57
00:03:14,480 --> 00:03:16,840
Speaker 1: You can turn the thermostat up before leaving and then

58
00:03:16,919 --> 00:03:19,119
Speaker 1: begin to cool it down when you're on your way home.

59
00:03:20,760 --> 00:03:23,480
Speaker 1: She also suggests closing the curtains if you're going to

60
00:03:23,520 --> 00:03:26,200
Speaker 1: be gone for more than a few hours. This will

61
00:03:26,240 --> 00:03:28,840
Speaker 1: effectively block out the sun so that your air conditioning

62
00:03:28,919 --> 00:03:31,240
Speaker 1: unit doesn't have to work so hard to stay ahead

63
00:03:31,240 --> 00:03:34,560
Speaker 1: of the heat. In areas that see extreme temperatures. This

64
00:03:34,600 --> 00:03:39,160
Speaker 1: can make an enormous difference. Energy Star, which is a

65
00:03:39,160 --> 00:03:41,880
Speaker 1: program run by the Department of Energy and the Environmental

66
00:03:41,880 --> 00:03:45,680
Speaker 1: Protection Agency, recommends keeping your thermostat at seventy eight degrees

67
00:03:45,680 --> 00:03:49,040
Speaker 1: fahrenheit that's twenty eight celsius or higher in the day,

68
00:03:49,120 --> 00:03:52,000
Speaker 1: and eighty five fahrenheit or twenty nine celsius when you're

69
00:03:52,000 --> 00:03:56,200
Speaker 1: away from home. If these temperatures seem too high to you,

70
00:03:56,440 --> 00:03:59,520
Speaker 1: consider the cooling your home to seventy eight degrees rather

71
00:03:59,560 --> 00:04:05,120
Speaker 1: than seven two could cut your electricity bill by Cress

72
00:04:05,120 --> 00:04:07,920
Speaker 1: Cup has a slightly different take on the thermostat issue,

73
00:04:08,360 --> 00:04:10,560
Speaker 1: as she said, raise it as high as you can

74
00:04:10,680 --> 00:04:13,920
Speaker 1: while still remaining comfortable, and this will vary by individual.

75
00:04:14,680 --> 00:04:17,360
Speaker 1: As a rule, raising the temperature by just two degrees

76
00:04:17,440 --> 00:04:22,360
Speaker 1: will help reduce cooling costs by five percent. A few

77
00:04:22,360 --> 00:04:25,600
Speaker 1: other measures can make a big difference in overall climate

78
00:04:25,640 --> 00:04:29,200
Speaker 1: related comfort, particularly if you've decided to raise the thermostatic

79
00:04:29,279 --> 00:04:32,039
Speaker 1: higher than you're used to. No one is to make

80
00:04:32,120 --> 00:04:36,360
Speaker 1: use of ceiling fans, Chriss said, Remember though, that fans

81
00:04:36,400 --> 00:04:39,839
Speaker 1: cool people, they don't change the temperature, so turn them

82
00:04:39,880 --> 00:04:44,520
Speaker 1: off when you leave the room. Air Conditioners have come

83
00:04:44,560 --> 00:04:47,719
Speaker 1: a long way even in the last decade. Modern units

84
00:04:47,760 --> 00:04:51,880
Speaker 1: can save on cooling energy costs compared with air conditioners

85
00:04:51,880 --> 00:04:55,359
Speaker 1: installed only ten years ago, and they're an even bigger

86
00:04:55,400 --> 00:04:58,520
Speaker 1: improvement on those of dinosaurs installed in the nineteen seventies

87
00:04:58,680 --> 00:05:02,640
Speaker 1: as they use between third in fifty less energy. So

88
00:05:02,760 --> 00:05:04,719
Speaker 1: if you've got an older system in a home that

89
00:05:04,760 --> 00:05:08,920
Speaker 1: you own, updating it might be worth the investment. Finally,

90
00:05:09,080 --> 00:05:12,080
Speaker 1: make sure your home is properly insulated so that cold

91
00:05:12,120 --> 00:05:15,560
Speaker 1: air isn't escaping out and warm air isn't creeping in.

92
00:05:20,520 --> 00:05:23,000
Speaker 1: Today's episode is based on the article should you turn

93
00:05:23,040 --> 00:05:24,880
