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 leaves fewer resources to address other issues. 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 coal use. The average Chinese has become more than 13 times richer.
Meanwhile, Beijing and numerous other Chinese metropolises are experiencing debilitating smog. About 1.2 million Chinese die prematurely each year because of outdoor air pollution. Measurements from Beijing show that over 16 percent of the 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 percent of GDP.
And yet the Chinese trade-off has been phenomenally beneficial. In 1982, the average Chinese earned $585 a year; last year, he earned $7,958. Meanwhile, the annual per capita environmental cost is $318. Most developing countries would 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 damage 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 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 percent 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 U.S. 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 3 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 10 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 3 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. While this might be part of the solution, it is 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 kilowatt hour. 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 percent 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 percent 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 3 billion energy-poor people and still end up with lower air pollution. It is easy and fairly cheap to cut coal pollution 90 percent 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 percent of the planet’s coal-fired power plants, including all of South Africa’s, because they emit too much carbon-dioxide. Al Gore’s climate adviser, James Hansen, argues that if we allow developing nations 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 percent of GDP by the end of the century, when the U.N. expects developing-world incomes to have risen by 1,400-1,800 percent.
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 trade-offs needed to improve poor people’s lives.
