The Power to Develop

Bjørn_LomborgBy   Bjørn Lomborg (Mareeg.com)CANBERRA – Trade-offs are an inherent part of life. We all recognize this from our
private budgets. To fix the roof, we may have to accept a less extravagant summer
vacation. When we pick a cheaper wine, we can splurge on dessert.

Trade-offs also pervade environmental policy: Cutting more of one pollutant, for
example, leaves fewer resources to address other issues. For example, coal is
phenomenally polluting, but it also provides for cheap and reliable power, which
drives development. Over the past 30 years, China has lifted 680 million people out
of poverty, mostly through the use of coal. The average Chinese has become more than
13 times richer.

At the same time, Beijing and numerous other Chinese metropolises are experiencing
debilitating smog, reminiscent of London in the 1950’s. About 1.2 million Chinese
die prematurely each year because of outdoor air pollution. Measurements from
Beijing show that upwards of 16% of the air pollution comes from coal. The World
Bank estimates that China’s total annual air-pollution costs – based on what Chinese
themselves indicate they are willing to pay to reduce their risk of dying – could be
as high as 4% of GDP.

And yet the Chinese trade-off has been phenomenally beneficial. In 1982, the average
Chinese earned $585 a year; last year, she earned $7,958. Meanwhile, the annual per
capita environmental cost is $318. So, not surprisingly, most other developing
countries would gratefully seize the opportunity to replicate China’s growth pattern
– including its pollution.

Of course, the Chinese could do more to cut air pollution. It is estimated that
meeting the World Health Organization’s interim standards could reduce damages by
$80 per capita. But that pales in comparison to the $600 increase in per capita
income in 2013.

Nonetheless, many who live in rich countries confidently declare that this trade-off
is not in the interest of the poor. The United States, the United Kingdom, and other
European countries announced this year that they will not support international
finance for coal-fired power plants in developing countries. These countries
abstained in 2010 when the World Bank helped finance South Africa’s Medupi
coal-fired power plant. Today, they would vote it down.

But Medupi will provide 10% of South Africa’s electricity and prevent rolling
blackouts. As the South African finance minister, Pravin Gordhan, explained, “to
sustain the growth rates we need to create jobs, we have no choice but to build new
generating capacity – relying on what, for now, remains our most abundant and
affordable energy source: coal.” The US government even acknowledged that, without a
coal-fired power plant, South Africa’s “economic recovery will suffer, adversely
impacting electrification, job creation, and social indicators.”

Energy poverty is even more acute for the three billion people – almost half of the
world’s population – who burn dung, cardboard, and twigs indoors to cook and keep
warm. The WHO estimates that while outdoor air pollution in developing-country
cities may be ten times higher than in advanced-country cities, average indoor air
pollution, caused by burning wood and dung, is a hundred times higher. Indeed,
indoor air pollution kills 3.5 million people each year, making it the world’s
deadliest environmental problem.

The world’s three billion energy-poor people need cheap electricity to cook and keep
warm. And, for the foreseeable future, that electricity will be generated by fossil
fuels.

Some environmental campaigners argue for cleaner stoves. But, while this might be
part of the solution, it is essentially telling the poor to live with slightly less
polluting open fires in their homes. Moreover, studies indicate that even
significant air-pollution reduction starting at high levels will have only a minor
impact.

Others claim that renewables are the way to go. Green energy, especially wind, can
indeed help African countries, for example, get some electricity to remote, rural
areas; but the grid will do the most good for the most people. According to a recent
World Bank study, distributed renewable energy “will be the lowest cost option for a
minority of households in Africa, even when likely cost reductions over the next 20
years are considered.” Popular solar lights cost almost $2 per kWh. Using hydro,
gas, and oil, the grid cost for the main population centers in Ethiopia, Ghana, and
Kenya will likely be $0.16-25 per kWh. In South Africa, where coal powers 90% of
electricity, the cost is just $0.09 per kWh.

True, electricity from coal will cause extra air pollution. But pollution from
indoor air pollution, which would disappear with electrification, accounts for 16%
of outdoor air pollution. Even assuming (unrealistically) that coal produces all of
the world’s air pollution, we could generate 250 kWh/year with coal for every one of
the three billion energy-poor people and still end up with lower air pollution.
Moreover, it is easy and fairly cheap to cut coal pollution 90% or more with
scrubbers.

For many opponents of coal, the issue is global warming. According to Christiana
Figueres, the United Nations climate chief, coal-fueled development has “an
unacceptably high cost to human and environmental health.” She argues that we need
to close 75% of the planet’s coal-fired power plants, including all of South
Africa’s, because they emit too much CO2. Al Gore’s climate adviser, James Hansen,
argues that if we allow developing countries to “come up to the level of the
developed world, then the planet is done for.”

Yes, the world needs to address global warming (mainly through higher investments in
green research and development, and by promoting exploitation of cheap,
less-polluting shale gas). But global warming will cause damage worth possibly 1-5%
of GDP by the end of the century, when the UN expects developing-world incomes to
have risen by 1,400-1,800%.

Meanwhile, poverty is killing millions right now, with an impact on global GDP that
is likely an order of magnitude higher. And too many people, however
well-intentioned, are unwilling to acknowledge the tradeoffs needed to improve poor
people’s lives.
