How to bring affordable sustainable electricity to Africa Rose M. Mutiso

So right now, nearly
one billion people globally

don’t have access
to electricity in their homes.

And in sub-Saharan Africa,

more than half of the population
remain in the dark.

So you probably all know
this image from NASA.

There’s a name for this darkness.

It’s called “energy poverty,”

and it has massive implications
for economic development

and social well-being.

One unique aspect of the energy
poverty problem in sub-Saharan Africa –

and by the way, in this talk
when I “energy,” I mean “electricity” –

one thing that’s unique about it is

there isn’t much legacy
infrastructure already in place

in many countries of the region.

So, for example, according to 2015 data,

the total installed electricity capacity
in sub-Saharan Africa

is only about 100 gigawatts.

That’s similar to that of the UK.

So this actually presents
a unique opportunity

to build an energy system
in the 21st century

almost from scratch.

The question is: How do you do that?

We could look back to the past
and replicate the ways

in which we’ve managed to bring
stable, affordable electricity

to a big part of the world’s population.

But we all know that that has
some well-known terrible side effects,

such as pollution and climate change,

in addition to being
costly and inefficient.

With Africa’s population set to quadruple
by the end of the century,

this is not a theoretical question.

Africa needs a lot of energy,
and it needs it fast,

because its population is booming
and its economy needs to develop.

So for most countries,
the general trajectory of electrification

has been as follows.

First, large-scale
grid infrastructure is put in place,

usually with significant
public investment.

That infrastructure then powers
productive centers,

such as factories,
agricultural mechanization,

commercial enterprises and the like.

And this then stimulates economic growth,

creating jobs, raising incomes

and producing a virtuous cycle

that helps more people
afford more appliances,

which then creates residential
demand for electricity.

But in sub-Saharan Africa,
despite decades of energy projects,

we haven’t really seen these benefits.

The energy projects have often
been characterized by waste,

corruption and inefficiency;

our rural electrification
rates are really low,

and our urban rates could be better;

the reliability of
our electricity is terrible;

and we have some of the highest
electricity prices in the whole world.

And on top of all of this,

we are now facing the impacts of
the growing climate catastrophe head-on.

So Africa will need
to find a different path.

And, as it turns out,
we are now witnessing

some pretty exciting disruption
in the African energy space.

This new path is called off-grid solar,

and it’s enabled by cheap solar panels,

advances in LED and battery technology,

and combined with
innovative business models.

So these off-grid solar products
typically range from a single light

to home system kits
that can charge phones,

power a television

or run a fan.

I want to be clear:

off-grid solar is a big deal in Africa.

I have worked in the sector for years,

and these products are enabling us
to extend basic energy services

to some of the world’s poorest,

raising their quality of life.

This is a very good
and a very important thing.

However, off-grid solar will not solve
energy poverty in Africa,

and for that matter,

neither will a top-down effort
to connect every unserved household

to the grid.

See, I’m not here to rehash
that played-out “on-versus-off-grid”

or “old-versus-new” debate.

Instead,

I believe that our inability
to grapple with and truly address

energy poverty in Africa

stems from three main sources.

First, we don’t really have
a clear understanding

of what energy poverty is,
or how deep it goes.

Second, we are avoiding
complex systemic issues

and prefer quick fixes.

And third, we are misdirecting
concerns about climate change.

Combined, these three mistakes are leading
us to impose a Western debate

on the future of energy

and falling back on paternalistic
attitudes towards Africa.

So let me try and unpack
these three questions.

First, what exactly is energy poverty?

The main energy poverty targeted indicator

is enshrined in the UN’s Seventh
Sustainable Development Goal,

or SDG 7.

It calls for 100 percent
of the world’s population

to have access to electricity
by the year 2030.

This binary threshold, however,

ignores the quality, reliability
or utility of the power,

though indicators
are currently being developed

that will try and capture these things.

However, the question of when
a household is considered “connected”

is not quite clear-cut.

So, for example, last year
the Indian Prime Minister Narendra Modi

declared all of the villages
in India electrified,

the criteria for electrification being

a transformer in every village
plus its public centers

and 10 percent – 10 percent –
of its households connected.

Meanwhile,

the International Energy Agency,
which tracks progress against SDG 7,

defines energy access as
50 kilowatt hours per person per year.

That’s enough to power
some light bulbs and charge a phone,

perhaps run a low-watt TV or fan
for a few hours a day.

Now, providing entry-level access
is an important first step,

but let’s not romanticize the situation.

By any standard, a few lights
and not much else

is still living in energy poverty.

And what’s more,

these energy poverty
indicators and targets

cover only residential use.

And yet, households account
for just about one quarter

of the world’s electricity consumption.

That’s because most of our power
is used in industries and for commerce.

Which brings me to my main point:

countries cannot grow out of poverty
without access to abundant,

affordable and reliable electricity
to power these productive centers,

or what I call “Energy for Growth.”

As you can see from this graph,

there’s simply no such thing
as a low-energy, high-income country.

It doesn’t exist.

And yet, three billion people in the world

currently live in countries without
reliable, affordable electricity –

not just to power their homes
but also their factories,

their office buildings, their data centers

and other economic activities.

Merely electrifying households
and microenterprises

cannot solve this deeper energy poverty.

To solve energy poverty,

we need to deliver reliable,
affordable electricity at scale,

to power economy-wide job creation
and income growth.

This need, however, bumps
against an emerging narrative that,

faced with climate change,

we all need to transition
from large, centralized power systems

to small-scale distributed power.

The growth of off-grid solar in Africa –

and let me repeat,
off-grid solar is a good thing –

but that growth fits nicely
into this narrative

and has led to those claims that Africa
is leapfrogging the old ways of energy

and building its power system
from the ground up,

one solar panel at a time.

It’s a nice, solicitous narrative,
but also quite naïve.

Like many narratives
of technological disruption,

often inspired by Silicon Valley,

it takes for granted the existing systems
that underpin all of this transformation.

You see, when it comes
to innovating and energy,

the West is working around the edges
of a system that is tried and tested.

And so all the sexy stuff –

the rooftop solar,

the smart household devices,
the electric vehicles –

all of this is built on top of a massive
and absolutely essential grid,

which itself exists within
a proven governance framework.

Even the most advanced
countries in the world

don’t have an example of an energy system
that is all edges and no center at scale.

So ultimately, no approach –

be it centralized or distributed,
renewable or fossil-based –

can succeed in solving energy poverty

without finding a way to deliver
reliable, affordable electricity

to Africa’s emerging industrial
and commercial sectors.

So, it’s not just lights
in every rural home.

It’s power for Africa’s cities
that are growing fast

and increasingly full
of young, capable people

in desperate need of a job.

This in turn will require
significant interconnectivity

and economies of scale,

making a robust and modern grid

a crucial piece of any
energy poverty solution.

So, our second mistake is falling
for the allure of the quick fix.

You see, energy poverty exists

within a complex socioeconomic
and political context.

And part of the appeal
of new electrification models

such as off-grid solar, for example,

is they can often bypass the glacial pace
and inefficiency of government.

See, with small systems you can skip
the bureaucracies and the utilities

and sell directly to customers.

But to confront energy poverty,

you cannot ignore governments,
you cannot ignore institutions,

you cannot ignore the many players
involved in making, moving

and using electricity at scale,

which is a way to say that when it comes
to providing energy for growth,

it’s not just about
innovating the technology,

it’s about the slow and hard work
of improving governance, institutions

and the broader macroenvironment.

OK, so this is all good and nice, you say.

But what about climate change?

How do we ensure a high-energy
future for everyone

while also curbing our emissions?

Well, we’ll have to make
some complex tradeoffs,

but I believe that
a high-energy future for Africa

is not mutually exclusive
to a low-carbon future.

And make no mistake:

the world cannot expect Africa
to remain in energy poverty

because of climate change.

(Applause)

Actually, the facts show
that the opposite is true.

Energy will be essential for Africa
to adapt to climate change

and build resilience.

You see, rising temperatures will mean
increased demand for space cooling

and cold storage.

Declining water tables will mean
increased pumped irrigation.

And extreme weather and rising sea levels
will require a significant expansion

and reinforcement of our infrastructure.

These are all energy-intensive activities.

So balancing climate change
and Africa’s pressing need

to transition to a high-energy future

will be tough.

But doing so is nonnegotiable;
we will have to find a way.

The first step is broadening
the terms of the debate

away from this either-or framing.

And we also must stop
romanticizing solutions

that distract us from the core challenges.

And let’s not also forget that Africa
is endowed with vast natural resources,

including significant renewable potential.

For example, in Kenya, where I’m from,

geothermal power accounts
for half of our electricity generation,

and with hydro being
the other major source,

we are already mainly powered
by renewable energy.

We also just brought online
Africa’s largest wind farm

and East Africa’s biggest solar facility.

(Applause)

In addition,

new technology means that we can now
run and design our power systems

and use energy more efficiently than ever,

doing more with less.

Energy efficiency
will be an important tool

in the fight against climate change.

So in closing, I’d just like to say that
Africa is a real place with real people,

navigating complex challenges
and major transitions,

just like any other region of the world.

(Applause)

And while each country and each region

has its social, economic
and political quirks,

the physics of electricity
are the same everywhere.

(Laughter) (Applause)

And the energy needs of our economies

are just as intensive as those
of any other economy.

So, the expansion
of household electrification

through a mix of
on- and off-grid solutions

has had an incredible impact in Africa.

But they are nowhere near sufficient
for solving energy poverty.

To solve energy poverty,

we need generation of electricity
from diverse sources at scale

and modern grids to power
a high-energy future,

in which Africans can enjoy
modern living standards

and well-paying jobs.

Africans deserve this,

and with one of every four people
in the world projected to be African

by the year 2100,

the planet needs it.

Thank you.

(Applause)

因此,目前,
全球有近 10 亿人家中

没有电。

而在撒哈拉以南非洲,

超过一半的人口
仍处于黑暗之中。

所以你们可能都知道
这张来自 NASA 的图像。

这种黑暗有一个名字。

这被称为“能源贫困”


它对经济发展

和社会福祉具有重大影响。

撒哈拉以南非洲能源贫困问题的一个独特方面

——顺便说一下,在这次谈话中,
当我“能源”时,我指的是“电力”——

它的独特之处

在于没有太多的遗留
基础设施 已经在

该地区的许多国家实施。

因此,例如,根据 2015 年的数据,

撒哈拉以南非洲

的总装机容量仅为 100 吉瓦左右。

这与英国的情况相似。

因此,这实际上提供
了一个几乎从零开始

构建 21 世纪能源系统的独特机会

问题是:你是怎么做到的?

我们可以回顾过去
并复制

我们为世界上很大一部分人口提供
稳定、负担得起的

电力的方式。

但我们都知道,除了成本高、效率低之外,它还有
一些众所周知的可怕副作用,

例如污染和气候变化

到本世纪末,非洲人口将翻两番

这不是一个理论上的问题。

非洲需要大量能源,
而且需要很快,

因为它的人口正在蓬勃发展
,经济需要发展。

因此,对于大多数国家来说,
电气化的总体轨迹

如下。

首先,大规模的
电网基础设施已经到位,

通常需要大量的
公共投资。

然后,该基础

设施为工厂、
农业机械化、

商业企业等生产中心提供动力。

然后这会刺激经济增长,

创造就业机会,提高收入

并产生良性循环

,帮助更多人
买得起更多电器,

从而创造居民
对电力的需求。

但在撒哈拉以南非洲,
尽管有数十年的能源项目,

我们还没有真正看到这些好处。

能源项目的
特点往往是浪费、

腐败和低效;

我们的农村电气化
率真的很低

,我们的城市电气化率可能会更好;

我们电力的可靠性很糟糕;

我们有一些世界上最高的
电价。

最重要的是,

我们现在正面临
着日益严重的气候灾难的影响。

所以非洲
需要另辟蹊径。

而且,事实证明,
我们现在正在目睹非洲能源领域出现

一些令人兴奋的
颠覆。

这条新路径被称为离网太阳能

,它由廉价的太阳能电池板、

LED 和电池技术的进步

以及
创新的商业模式实现。

因此,这些离网太阳能产品的
范围通常从单灯

到可以为手机充电、

为电视供电

或运行风扇的家庭系统套件。

我想明确一点:

离网太阳能在非洲很重要。

我在该行业工作了多年

,这些产品使我们
能够将基本能源服务扩展

到世界上一些最贫穷的人,

提高他们的生活质量。

这是一件非常好的
事情,也是一件非常重要的事情。

然而,离网太阳能不会解决
非洲的能源贫困

问题,就此而言,

自上而下的努力也不
会将每个没有服务的家庭连接

到电网。

看,我不是在这里重新讨论
已经播出的“on-vs-off-grid”

或“old-vs-new”辩论。

相反,

我认为我们无法
应对并真正解决

非洲的能源贫困

源于三个主要来源。

首先,我们并没有
真正清楚地

了解什么是能源贫困,
或者它的深度。

其次,我们正在避免
复杂的系统性问题,

并且更喜欢快速修复。

第三,我们误导
了对气候变化的担忧。

综合起来,这三个错误导致
我们

对能源的未来进行西方辩论,

并退回
对非洲的家长式态度。

所以让我试着解开
这三个问题。

首先,究竟什么是能源贫困?

主要的能源贫困目标指标

被载入联合国的第七个
可持续发展目标,

即 SDG 7。

它要求到 2030 年
世界人口的 100%

用上电。

然而,这个二元阈值

忽略了质量、可靠性
或权力的效用,

尽管
目前正在开发

指标来尝试捕捉这些东西。

然而,
一个家庭何时被认为是“连接”

的问题并不十分明确。

因此,例如,
去年印度总理纳伦德拉·莫迪

宣布印度的所有村庄都实现了
电气化,

电气化的标准

是每个村庄
加上其公共中心

和 10% - 10%

  • 的家庭连接的变压器。

与此同时

,追踪 SDG 7 进展情况的国际能源署

将能源获取定义为
每人每年 50 千瓦时。

这足以为
一些灯泡供电并为手机充电,

也许每天可以运行几个小时的低功率电视或
风扇。

现在,提供入门级访问权限
是重要的第一步,

但我们不要把这种情况浪漫化。

以任何标准来看,只有几盏灯
和其他不多

的灯仍然生活在能源匮乏中。

而且,

这些能源贫困
指标和目标

仅涵盖住宅用途。

然而,家庭仅占

世界用电量的四分之一左右。

那是因为我们的大部分电力
都用于工业和商业。

这让我想到了我的主要观点:

如果
没有充足的、

负担得起的和可靠的
电力来为这些生产中心供电,

或者我称之为“增长的能源”,国家就无法摆脱贫困。

从这张图中可以看出,

根本不
存在低能源、高收入的国家。

它不存在。

然而,目前世界上有 30 亿人

生活在没有
可靠、负担得起的电力的国家——

不仅为他们的家庭供电
,还为他们的工厂

、办公楼、数据中心

和其他经济活动供电。

仅仅让家庭
和微型企业通电并

不能解决这种更深层次的能源贫困。

为了解决能源贫困,

我们需要大规模提供可靠、
负担得起的电力,

以推动整个经济的就业机会
和收入增长。

然而,这种需求
与一种新兴的说法相悖,即

面对气候变化,

我们都需要
从大型集中式电力系统过渡

到小型分布式电力系统。

非洲离网太阳能的增长

——让我再说一遍,
离网太阳能是一件好事——

但这种增长很好地适应
了这种

说法,并导致了那些声称非洲
正在超越旧的能源方式

和 从头开始构建其电力系统

一次一个太阳能电池板。

这是一个很好的,热心的叙述,
但也很幼稚。

就像许多

经常受到硅谷启发的技术颠覆的叙述一样,

它认为支持所有这种转变的现有系统是理所当然的

你看,当
谈到创新和能源时

,西方正在围绕
一个经过试验和测试的系统的边缘工作。

所以所有性感的东西

——屋顶太阳能

、智能家居设备
、电动汽车——

所有这些都建立在一个庞大
且绝对必要的电网之上,而电网

本身存在于
一个经过验证的治理框架内。

即使是世界上最先进的
国家,

也没有一个能源系统的例子,
即所有边缘都没有规模中心。

因此,最终,任何方法

——无论是集中式还是分布式、
可再生能源还是基于化石燃料——

都无法成功解决能源贫困问题,

除非找到向非洲新兴工业和商业部门提供
可靠、负担得起的电力的方法

所以,这不仅仅是
每个农村家庭的灯。

对于非洲的城市来说,这是一种力量,这些城市
发展迅速

,越来越多
的年轻人,有能力的

人迫切需要一份工作。

这反过来将需要
显着的互连性

和规模经济,

使强大的现代电网

成为任何
能源贫困解决方案的关键部分。

所以,我们的第二个错误是
迷上了快速修复的魅力。

你看,能源贫困存在

于复杂的社会经济
和政治环境中。

例如,离网太阳能等新型电气化模式的部分吸引力在于,

它们通常可以绕过政府的缓慢步伐
和低效率。

看,使用小型系统,您可以
跳过官僚机构和公用事业

,直接向客户销售。

但是要面对能源贫困,

你不能忽视政府,
你不能忽视机构,

你不能忽视
参与大规模生产、运输

和使用电力的许多参与者,

这就是说,在
为增长提供能源时,

它是 不仅仅是
技术创新,


在于改善治理、制度

和更广泛的宏观环境的缓慢而艰苦的工作。

好的,所以这一切都很好,你说。

但是气候变化呢?

我们如何

在控制排放的同时确保每个人的高能源未来?

好吧,我们将不得不做出
一些复杂的权衡,

但我相信
非洲的高能源未来

与低碳未来并不相互排斥。

别搞错了

:世界不能指望非洲
会因为气候变化而继续处于能源贫困之中

(鼓掌)

其实
事实恰恰相反。

能源对于非洲
适应气候变化

和建立复原力至关重要。

你看,气温上升将意味着
对空间冷却

和冷藏的需求增加。

地下水位下降将意味着
增加抽水灌溉。

极端天气和不断上升的海平面
将需要

我们的基础设施进行重大扩展和加固。

这些都是能源密集型活动。

因此,平衡气候变化
和非洲

向高能源未来过渡的迫切需要

将是艰难的。

但是这样做是没有商量余地的;
我们必须想办法。

第一步是
扩大辩论的范围,

远离这种非此即彼的框架。

我们还必须停止

将分散我们注意力从核心挑战上移开的解决方案浪漫化。

我们也不要忘记,
非洲拥有丰富的自然资源,

包括巨大的可再生潜力。

例如,在我来自的肯尼亚,

地热发电
占我们发电量的一半,

而水电
是另一个主要来源,

我们已经主要
由可再生能源供电。

我们还刚刚上线了
非洲最大的风电场

和东非最大的太阳能设施。

(掌声)

此外,

新技术意味着我们现在可以
运行和设计我们的电力系统

,比以往任何时候都更有效地使用能源

,事半功倍。

能源效率
将成为

应对气候变化的重要工具。

所以最后,我只想说,
非洲是一个真实的地方,有真实的人,可以

应对复杂的挑战
和重大转变,

就像世界上任何其他地区一样。

(掌声

)虽然每个国家和每个地区

都有其社会、经济
和政治方面的怪癖,

但电的物理特性
在任何地方都是相同的。

(笑声)(掌声

) 我们经济体的能源需求与

其他任何经济体一样密集

因此,

通过结合使用
并网和离网解决方案扩大家庭电气化

对非洲产生了令人难以置信的影响。

但它们远
不足以解决能源贫困问题。

为了解决能源贫困问题,

我们需要
大规模地从各种来源发电

并使用现代电网来
为高能源未来提供动力

,让非洲人可以享受
现代生活水平

和高薪工作。

非洲人应得的这一点,预计到 2100

年,世界上每四个人中就有一个
是非洲人

这个星球需要它。

谢谢你。

(掌声)
