Shale oil and gas boom puts global warming issue on the back burner

Peter Schwartz says the prospect of cheap, abundant oil and gas from shale may be good news for the economy, but augurs badly for renewable energy and climate change

A technological revolution is transforming the world's energy landscape as we move from an expectation of shortages of oil and gas to a new era of abundance. The development of natural gas from shale, that has already taken off in the US, and a variety of technologies are creating new options for oil development, so much so that the notion of peak oil has vanished from the conversation.

We can expect some consequences. Chief among them is the fact that, as energy gets more abundant, the incentives to develop clean, renewable energy drop dramatically. As a result, we are no longer looking at an age of increasing solar, wind and nuclear power. We are moving into a renewed hydrocarbon era of oil and gas. That's very bad news for climate change.

The natural gas revolution is already playing out in the US. Only a few years ago, domestic gas supplies were running out, demand was rising, and prices were shooting up. The US was desperate to import foreign gas.

Fast-forward to today, and US companies are now trying to figure out how to convert import terminals into export facilities. What made tens of billions dollars' worth of infrastructure almost worthless, seemingly overnight? Shale gas.

The United States is well endowed with enormous deposits of shale rock - soft, but brittle rock that is dense with hydrocarbons. Sometimes the hydrocarbons take the form of oil, but mostly it is in the form of natural gas.

Over the last 30 years, the technology needed to break up those rocks to get at this gas has steadily advanced. As the techniques matured, and the price of gas rose, major energy companies moved aggressively to exploit these new fields. The result has been an explosion in natural gas production. It has led to an 80 per cent fall in gas prices and the complete collapse of the natural gas import business.

Cheap gas will have three major affects. First, it will delay or kill most new competing sources of electricity production - be they coal, nuclear, solar, or anything else.

Secondly, natural gas has become so cheap and abundant that it will soon start to win over some transportation markets. Trucks, buses, delivery vans and a variety of commercial and fleet vehicles all can easily be converted to natural gas.

The third impact will be on climate change. Most new power plants will now be natural gas-based. While natural gas is cleaner than coal, it is obviously dirtier than nuclear, wind and solar. While some ageing coal plants will be replaced, decreasing overall carbon dioxide output, far more nuclear, solar and wind plants will be deferred or even cancelled.

A number of Asian countries are likely to find shale gas inside their borders, especially today's coal producers China, India and Australia. Not all shale deposits will be technically or economically viable, but over time many Asian countries will start producing some shale gas, especially where the gas infrastructure already exists.

In Asia, gas is used less for electricity and more for heating, cooking, industrial inputs and even transportation. Abundant gas will almost certainly lead gas more into electricity, competing with coal, nuclear and renewables. And it is not hard to imagine more gas-to-liquids plants of the sort that is now operating on a large scale in Qatar, employing cheap local gas to produce diesel fuel for the region.

And what cheap gas is doing to renewables, abundant oil will soon do to hybrid and electric vehicles.

Gas markets are regional but the oil market is global and the resurgence in oil production is also worldwide.

Oil production in the US is on the rise, thanks to the same fracking technology that has given it loads of natural gas. Soon it will be pulling more oil out of Alaska. This uptick, combined with shrinking demand thanks to successful efforts at efficiency, means that US import needs have shrunken and can now be met by its neighbours to the north and south.

In the near future, the US will finally cease to be dependent upon Middle East oil. (That said, China is likely to see its dependence grow. One day US naval ships may leave the Gulf only to be replaced by the Chinese navy.)

The most recent spike in global oil prices has been entirely driven by the political turmoil in the Middle East and Africa. Sanctions have reduced Iranian exports, Iraq is still not back up to full capacity, Libya, Syria, Yemen and Sudan are all pumping less thanks to civil turmoil. But when the politically shuttered oil comes back, oil prices will fall, eventually to somewhere between US$75 to US$100 a barrel.

Relatively steady oil prices, and the knowledge that we're not about to run out, will have a significant impact on the vehicle fleet. Carmakers will no longer feel the relentless drive for more efficient vehicles. Other industries that rely on oil - airlines, shipping, trucking and railroads - will experience similar relief in the demands put on them to improve efficiency.

The result: starting right now the American, Asian and global energy markets will once again be dominated by oil and gas. Renewables, coal, nuclear and eventually efforts to make more efficient buildings, planes and cars will all be losers. There is a risk that just as the auto industry is bringing a new generation of electric vehicles to market, the buyers - and politicians who offer subsidies for them - might lose interest in them. And many of the huge investments that have gone into solar and wind power are likely to go bad.

The ultimate losers, though, will likely be all of us. The new age of hydrocarbons - while possibly more stable geopolitically - will be just as damaging to our climate. Unfortunately, the seeds of this cycle have already been sown.
