Phasing Out of Fossil Fuel Phenomenal

Bringing cleaner energy closer need to be one of the next global development goals, reflects Bjørn Lomborg (PhD), an adjunct professor at the Copenhagen Business School and director of the Copenhagen Consensus Center (CCC), whose is also the author of The Skeptical Environmentalist and Cool It and How To Spend $75 Billion to Make the World a Better Place.

Nutritious food, clean water and basic healthcare for all may be obvious high-priority targets for the international community, but we should not ignore energy. Reliable and affordable energy is as vital for today’s developing and emerging economies as it was before the Industrial Revolution. Driven mostly by its five-fold increase in coal use, China’s economy has grown 18-fold over the past thirty years, while lifting 680 million people out of poverty.

The energy ladder is a way of visualising stages of development. This starts with what we call traditional biofuels – firewood, dung and crop waste. Almost three billion people use these for cooking and heating indoors, which is so polluting that the World Health Organisation (WHO) estimates they kill one of every 13 people that die on the planet.

The next step on the ladder is ‘transition fuels’ such as kerosene, charcoal and liquified petroleum gas, while the top of the ladder is electricity, which thankfully makes no pollution inside your home. Because electricity is often powered by fossil fuels, it does contribute to the problem of global warming.

Hence, an alluring option could be to move to clean energy, like wind, solar and hydro. Some suggest that developing countries should skip the fossil step and move right to clean energy. However, rich countries are already finding the move away from coal and oil to be difficult, and there are no easy answers for developing economies.

Today’s crucial question is: what should the world prioritise?

Fifteen years ago, the world agreed the Millennium Development Goals (MDGs), ambitious targets to tackle poverty, hunger, health and education. These goals have directed lots of international aid and mostly led to improvement, although much remains to be done.

Now, the United Nations is considering the next set of targets for 2015-2030. Some argue that we should continue with the few, sharp targets from the MDGs, since we are still not done. Others point out that other issues, like environment and social justice, also need attention.

The Copenhagen Consensus Centre, which I preside over, is helping to bring better information to this discussion. We have asked some of the world’s top economists to make analyses within all major challenge areas, estimating the economic, social and environmental costs and benefits of different targets.

So, should the almost-three billion people cooking with toxic open fires take higher priority than the broader, long term objective of cutting back on fossil fuel use?

It turns out there are smart ways to help on both accounts, say economists Isabel Galiana and Amy Sopinka.

Burning firewood and dung on open indoor fires is inefficient and causes horrendous air pollution. More than four million people each year die from respiratory illness because of smoke from indoor open fires. In Ethiopia alone, the WHO estimates 45,700 people die each year.

Most of these are women and young children, who are also the ones spending their time fetching firewood, often from quite far away. Providing cleaner cooking facilities – efficient stoves which run on liquefied gas – would improve health, increase productivity, allow women to spend time earning money and children to go to school.

The economic benefits of getting everyone off dung and wood are as high as the human welfare ones: more than 500 billion dollars each year. Costs would be much lower, about 60 billion dollars annually, including grants and subsidies to purchase stoves. Every dollar spent would buy almost nine dollars of benefits, which is a very good way to help.

However, the economists also provide a more realistic target, which turns out to be even more efficient. Since it is awfully hard to get to 100pc, they suggest providing modern cooking fuels to 30pc.

This will still help 780 million people, but at the much lower cost of 11 billion dollars annually. For every dollar spent, we would do more than 14 dollars worth of good.

While clean cooking is important, electricity can bring different benefits. Lighting means that students can study after dark, clinics can refrigerate vaccines, and water can be pumped from wells so that women do not have to walk miles to fetch it. About 68pc of sub-Saharan Africa still miss access to electricity, according to 2012 data by the International Energy Agency (IEA). Some 77pc of Ethiopia, or 70 million people, still lack access to electricity.

The value of getting electricity to everyone is about 380 billion dollars annually. The cost is more difficult to work out. To provide electricity to everyone would need the equivalent of 250 more power stations but many rural areas might best be served by solar panels and batteries.

This is not an ideal solution but would still be enough to make an enormous improvement to people’s lives. The overall cost is probably around 75 billion dollars per year, which still does five dollars of benefits for each dollar spent.

If we want to tackle global warming, on the other hand, there are some targets we should be weary of. One prominent target suggests doubling the world’s share of renewables, particularly solar and wind, but this turns out to be a rather ineffective use of resources. The extra costs of coping with the intermittent and unpredictable output of renewables make them expensive and the cost likely to be higher than the benefits.

However, the world spends 544 billion dollars in fossil fuel subsidies, almost exclusively in third world countries. This drains public budgets from being able to provide health and education, while encouraging higher CO₂ emissions.

Moreover, gasoline subsidies mostly help rich people, because they are the only ones to afford a car. To phase out fossil fuel subsidies would be a phenomenal target, because it would cut CO₂ while saving money for other and better public uses. The economists estimate that every dollar in costs would do more than 15 dollars of climate and public good.

With such high-return targets, the economic evidence shows that – if carefully chosen – energy targets should definitely be part of the promises for the next 15 years.
