00:00:01,920 --> 00:00:06,360
Speaker 1: Welcome to Brainstuff the production of I Heart Radio, Hey

2
00:00:06,440 --> 00:00:11,440
Speaker 1: brain Stuff Lauren Bogibom here. America's famous yellow school buses

3
00:00:11,560 --> 00:00:15,120
Speaker 1: have been slowly going electric, but more still will be

4
00:00:15,120 --> 00:00:17,880
Speaker 1: plugging in soon, thanks in large part to the one

5
00:00:17,920 --> 00:00:22,000
Speaker 1: point to twillion dollar bipartisan Infrastructure bill passed by the

6
00:00:22,040 --> 00:00:27,480
Speaker 1: US Senate auguste. While the bill has not yet been

7
00:00:27,480 --> 00:00:31,200
Speaker 1: passed into law, and many in the sustainable transportation community

8
00:00:31,320 --> 00:00:33,960
Speaker 1: are already excited about what this bill could mean for

9
00:00:34,000 --> 00:00:37,479
Speaker 1: the possibility of electrifying more of the US's fleet of

10
00:00:37,479 --> 00:00:40,519
Speaker 1: four hundred and eighty thousand school buses, and how that

11
00:00:40,600 --> 00:00:45,080
Speaker 1: could help lower emissions and improve air quality. Of the

12
00:00:45,080 --> 00:00:48,520
Speaker 1: one point to trillion dollar infrastructure bill, two point five

13
00:00:48,520 --> 00:00:52,680
Speaker 1: billion is earmarked for zero emissions buses, enough for roughly

14
00:00:52,720 --> 00:00:56,480
Speaker 1: eleven thousand electric vehicles, and another two point five billion

15
00:00:56,560 --> 00:00:59,600
Speaker 1: for low emission buses, which could be fueled by natural

16
00:00:59,640 --> 00:01:03,480
Speaker 1: gas or propane. While this may seem like a lot

17
00:01:03,520 --> 00:01:06,880
Speaker 1: of money, it's significantly less than what President Joe Biden

18
00:01:06,920 --> 00:01:09,600
Speaker 1: initially proposed in March of this year, which was a

19
00:01:09,720 --> 00:01:12,840
Speaker 1: hundred and seventy four billion dollar lump sum to boost

20
00:01:12,880 --> 00:01:16,880
Speaker 1: the electric vehicle market, including nine thousand school buses instead

21
00:01:16,920 --> 00:01:18,920
Speaker 1: of the eleven thousand that the bill would now cover.

22
00:01:20,920 --> 00:01:24,560
Speaker 1: So why school buses? There are a lot of reasons

23
00:01:24,560 --> 00:01:27,600
Speaker 1: it makes sense for school buses to go electric. First,

24
00:01:27,800 --> 00:01:30,080
Speaker 1: most new electric buses have a range of up to

25
00:01:30,120 --> 00:01:32,919
Speaker 1: a hundred and twenty miles. That's a hundred nine KOs

26
00:01:33,040 --> 00:01:35,760
Speaker 1: on a single charge, which is plenty far enough for

27
00:01:35,800 --> 00:01:39,840
Speaker 1: the average school bus route on. Second, some charging systems

28
00:01:39,880 --> 00:01:43,360
Speaker 1: can charge a bus in just ninety minutes. Plus, Electric

29
00:01:43,400 --> 00:01:47,120
Speaker 1: buses also require a lot less maintenance than their diesel counterparts,

30
00:01:48,480 --> 00:01:51,880
Speaker 1: but it's also simple numbers. School buses currently make up

31
00:01:51,880 --> 00:01:54,880
Speaker 1: around of the buses on the roads in the US,

32
00:01:54,920 --> 00:02:00,320
Speaker 1: and those run on high polluting diesel fuel the right now,

33
00:02:00,440 --> 00:02:04,680
Speaker 1: less than one percent are electric. For context, the entire

34
00:02:04,880 --> 00:02:08,080
Speaker 1: US transit fleet has around four and eighty thousand school

35
00:02:08,080 --> 00:02:12,320
Speaker 1: buses and just seventy public transportation buses. That's less than

36
00:02:12,360 --> 00:02:16,080
Speaker 1: fift percent of the number of school buses. For the article,

37
00:02:16,120 --> 00:02:18,359
Speaker 1: this episode is based on how Stuff Works. Spoke with

38
00:02:18,480 --> 00:02:22,040
Speaker 1: Lauren Justice, development director at the Center for Transportation and

39
00:02:22,080 --> 00:02:26,760
Speaker 1: the Environment. She said transportation is the largest contributor to

40
00:02:26,760 --> 00:02:30,119
Speaker 1: greenhouse gas emissions in the US. The medium and heavy

41
00:02:30,200 --> 00:02:33,960
Speaker 1: duty sector produces more than percent of these emissions, despite

42
00:02:33,960 --> 00:02:36,760
Speaker 1: comprising less than five percent of vehicles on the road.

43
00:02:37,840 --> 00:02:41,120
Speaker 1: If the entire school bus fleet were electrified, greenhouse gas

44
00:02:41,120 --> 00:02:43,880
Speaker 1: emissions from all buses in the US would be reduced

45
00:02:43,960 --> 00:02:48,919
Speaker 1: by around fifty Along with the issue of adding greenhouse

46
00:02:48,919 --> 00:02:52,560
Speaker 1: gases into the atmosphere, thus increasing global warming and its

47
00:02:52,600 --> 00:02:56,799
Speaker 1: associated risks, these emissions are also harmful for the twenty

48
00:02:56,800 --> 00:03:00,600
Speaker 1: million school children who ride these buses to school. Not

49
00:03:00,720 --> 00:03:03,240
Speaker 1: only are these buses emitting in the neighborhoods through which

50
00:03:03,240 --> 00:03:06,520
Speaker 1: they drive, but the pollution inside the bus can actually

51
00:03:06,520 --> 00:03:11,240
Speaker 1: be up to twelve times higher than ambient levels. In addition,

52
00:03:11,360 --> 00:03:15,080
Speaker 1: it's an issue of equity. According to the World Resources Institute,

53
00:03:15,240 --> 00:03:18,360
Speaker 1: students from low income communities are particularly exposed to this

54
00:03:18,440 --> 00:03:22,160
Speaker 1: toxic pollution, and some sixty percent of students from low

55
00:03:22,240 --> 00:03:25,240
Speaker 1: income families use buses to get to and from school,

56
00:03:25,600 --> 00:03:28,960
Speaker 1: compared with forty five percent of students from higher income families,

57
00:03:29,400 --> 00:03:32,560
Speaker 1: an issue that's exacerbated in communities of color due to

58
00:03:32,600 --> 00:03:36,400
Speaker 1: America's history of racist economic policies in both the government

59
00:03:36,440 --> 00:03:40,800
Speaker 1: and private sector that concentrated those communities closer to highways

60
00:03:40,920 --> 00:03:43,840
Speaker 1: and policies from zoning, to housing, to lending to the

61
00:03:43,960 --> 00:03:48,880
Speaker 1: very construction of our highway system. And Justice said switching

62
00:03:48,920 --> 00:03:51,640
Speaker 1: from diesel powered school buses to electric could avoid an

63
00:03:51,680 --> 00:03:54,800
Speaker 1: average a five point three million tons of greenhouse gas

64
00:03:54,800 --> 00:03:58,280
Speaker 1: emissions each year and over seven hundred thousand pounds that's

65
00:03:58,320 --> 00:04:02,000
Speaker 1: three hundred thousand kilos of ep A criteria pollutants admitted

66
00:04:02,040 --> 00:04:07,760
Speaker 1: near children. So can it be done? Advocates believe it

67
00:04:07,840 --> 00:04:10,520
Speaker 1: can be, but they say much more money needs to

68
00:04:10,520 --> 00:04:13,400
Speaker 1: be allocated to the issue, and that the infrastructure bill

69
00:04:13,680 --> 00:04:16,880
Speaker 1: is definitely not enough on its own. And it's not

70
00:04:16,920 --> 00:04:19,479
Speaker 1: just about money. There also need to be plans in

71
00:04:19,560 --> 00:04:22,919
Speaker 1: place to help school districts through the transition to electric buses,

72
00:04:23,640 --> 00:04:26,839
Speaker 1: and Justice said the critical piece that any successful plan

73
00:04:27,000 --> 00:04:29,960
Speaker 1: must include is an avenue for school districts to receive

74
00:04:30,120 --> 00:04:35,600
Speaker 1: technical assistance. While most school buses are still diesel powered,

75
00:04:35,880 --> 00:04:38,679
Speaker 1: some districts have been adding electric buses to their fleets.

76
00:04:39,160 --> 00:04:42,320
Speaker 1: In Maryland, for example, the Montgomery County Public School System

77
00:04:42,400 --> 00:04:44,960
Speaker 1: has plans to get three hundred and twenty six electric

78
00:04:44,960 --> 00:04:48,000
Speaker 1: school buses over the next four years. This is the

79
00:04:48,080 --> 00:04:52,240
Speaker 1: largest commitment by any single school district today. Thirty three

80
00:04:52,279 --> 00:04:58,200
Speaker 1: states have electric school buses announced, procured, delivered, or in operation. However,

81
00:04:58,360 --> 00:05:02,080
Speaker 1: as previously mentioned, the is inequality baked into the system,

82
00:05:02,440 --> 00:05:05,360
Speaker 1: and that's just as true for which areas will get

83
00:05:05,360 --> 00:05:09,359
Speaker 1: more electric school buses more quickly. Already, the largest share

84
00:05:09,520 --> 00:05:12,400
Speaker 1: thirty percent of school districts with at least one electric

85
00:05:12,440 --> 00:05:15,520
Speaker 1: school bus, are in suburban areas, which tend to be wealthier.

86
00:05:16,400 --> 00:05:20,400
Speaker 1: In addition, about sixty of all committed future electric buses

87
00:05:20,520 --> 00:05:24,520
Speaker 1: are in suburban areas, versus just percent in cities, seven

88
00:05:24,520 --> 00:05:29,440
Speaker 1: percent in towns, and six percent in rural areas. Along

89
00:05:29,440 --> 00:05:32,240
Speaker 1: with the infrastructure bill, there are numerous other programs and

90
00:05:32,320 --> 00:05:36,640
Speaker 1: political initiatives to electrify the nation's school buses. In February

91
00:05:36,640 --> 00:05:39,440
Speaker 1: of this year, the Clean school Bus Act was reintroduced

92
00:05:39,480 --> 00:05:42,440
Speaker 1: in the US Senate and the House of Representatives. This

93
00:05:42,480 --> 00:05:45,480
Speaker 1: act would establish a Clean school Bus Grant program to

94
00:05:45,560 --> 00:05:50,120
Speaker 1: award grants to replace existing school buses with electric ones. However,

95
00:05:50,200 --> 00:05:54,840
Speaker 1: as of now, the bill is stalled in subcommittee. Meanwhile,

96
00:05:55,000 --> 00:05:58,520
Speaker 1: the Federal Transit Authorities Low or No Emission Vehicle Program

97
00:05:58,760 --> 00:06:02,919
Speaker 1: allocates roughly two million dollars in funding for low and

98
00:06:03,000 --> 00:06:06,920
Speaker 1: no emissions buses and the facilities that support them. Its

99
00:06:06,960 --> 00:06:09,560
Speaker 1: goal is to support the Infrastructure Bill to reduce greenhouse

100
00:06:09,600 --> 00:06:14,200
Speaker 1: gas emissions by by the end of the decade. And

101
00:06:14,440 --> 00:06:18,080
Speaker 1: speaking of funding, electric school buses do cost more than

102
00:06:18,120 --> 00:06:21,000
Speaker 1: diesel powered, but they can lead to long term savings

103
00:06:21,000 --> 00:06:24,960
Speaker 1: for school districts who purchase them. For several reasons, electricity

104
00:06:25,080 --> 00:06:28,119
Speaker 1: is typically less expensive than diesel fuel, and as said above,

105
00:06:28,320 --> 00:06:32,480
Speaker 1: electric buses require less maintenance. Plus, if the districts equip

106
00:06:32,600 --> 00:06:35,440
Speaker 1: their schools with vehicle to grid technology, they can both

107
00:06:35,520 --> 00:06:38,360
Speaker 1: draw energy from and return it to the electrical grid.

108
00:06:40,720 --> 00:06:44,240
Speaker 1: A While Justice and other clean transportation advocates are pleased

109
00:06:44,279 --> 00:06:47,920
Speaker 1: to the Infrastructure Bill and local governments are addressing this problem,

110
00:06:47,960 --> 00:06:49,800
Speaker 1: they know that there's still a long way to go

111
00:06:49,960 --> 00:06:53,280
Speaker 1: when it comes to electrifying school buses in the United States.

112
00:06:58,800 --> 00:07:01,520
Speaker 1: Today's episode is based on the article why you want
