Plenty of Energy

Last week's New York Times had an article arguing that there are plenty of fossil fuels available to meet projected demand for coming decades.  If that is the case, then all the more reason for accelerated efforts to increase that demand by expanding access and to put a small price on today's energy supply, while it is plentiful and relatively cheap, in order raise the funds necessary to invest in innovation to build a bridge to tomorrow.

Here is an excerpt:
Energy experts now predict decades of residential and commercial power at reasonable prices. Simply put, the world of energy has once again been turned upside down.

“Oil and gas will continue to be pillars for global energy supply for decades to come,” said James Burkhard, a managing director of IHS CERA, an energy consulting firm. “The competitiveness of oil and gas and the scale at which they are produced mean that there are no readily available substitutes in either one year or 20 years.”

Some unpleasant though predictable consequences are likely, of course, as the disaster in the Gulf of Mexico this spring demonstrated. Some environmentalists say that gas from shale depends on drilling techniques and chemicals that may jeopardize groundwater supplies, and that a growing dependence on Canadian oil sands is more dangerous for the climate than most conventional oils because mining and processing of the sands require so much energy and a loss of forests.

And while moderately priced oil and gas bring economic relief, they also make renewable sources of energy like wind and solar relatively expensive and less attractive to investors unless governments impose a price on carbon emissions.

“When wind guys talk to each other,” said Michael Skelly, president of Clean Line Energy Partners, a developer of transmission lines for renewable energy, “they say, ‘Damn, what are we going to do about the price of natural gas?’ ”

Oil and gas executives say they provide a necessary energy bridge; that because both oil and gas have a fraction of the carbon-burning intensity of coal, it makes sense to use them until wind, solar, geothermal and the rest become commercially viable.

“We should celebrate the fact that we have enough oil and gas to carry us forward until a new energy technology can take their place,” said Robert N. Ryan Jr., Chevron’s vice president for global exploration.

Mr. Skelly and other renewable energy entrepreneurs counter that without a government policy fixing a price on carbon emissions through a tax or cap and trade, the hydrocarbon bridge could go on and on without end.
For those interested in stemming the accumulating carbon dioxide in the atmonsphere, even adopting agressive policies in that direction won't change the underlying dynamics:
Even in an alternative world where there is a concerted, coordinated effort to reduce future carbon emissions sharply, the International Energy Agency projected oil demand would peak at 88 million barrels a day around 2020, then decline to 81 million barrels a day in 2035 — just fractionally less than today’s consumption.

Natural gas use, meanwhile, would increase by 15 percent from current levels by 2035. In contrast, global coal use would dip a bit, while nuclear power and renewable forms of energy would grow considerably.

No matter what finally plays out, energy experts expect there will be plenty, perhaps even an abundance, of oil and gas. IHS CERA, which monitors oil and gas fields around the world, projects that productive capacity for liquid fuels could rise to 112 million barrels a day in 2030 (including 2.75 million barrels in biofuels), from 92.6 million barrels a day this year.

“The estimates for how much oil there is in the world continue to increase,” said William M. Colton, Exxon Mobil’s vice president for corporate strategic planning. “There’s enough oil to supply the world’s needs as far as anyone can see.”

More promising still is that the growing oil production comes from a variety of sources — making the world less vulnerable to a price war with the Organization of the Petroleum Exporting Countries or an outbreak of violence in a major producing country like Nigeria. As IHS CERA and other oil analysts see it, new oil is going to come from both conventional and unconventional sources — from anticipated expansions of fields in Iraq and Saudi Arabia and from a continued expansion of deepwater drilling off Africa and Brazil, in the Gulf of Mexico and across the Arctic, where hopes are high in the oil world, although little exploration has yet been done.

The vast oil sands fields in western Canada, deemed uneconomical by many oil companies as few as 15 years ago, are now as important to global supply growth as the continuing expansions of fields in Saudi Arabia, the current No. 1 producer.

“We’ve got a wealth of opportunities to address around the world,” said Mr. Ryan, Chevron’s vice president.

“We have quite a few deepwater settings all over the world, some of them very new, like the Black Sea. There are Arctic settings. We have efforts under way re-exploring Nigeria, Angola, Australia. The easy stuff has been found, that’s true, but in the end, we still have many basins in the world to explore or to re-explore.”
It is not necessary to agree with rosy scenarios of energy abundance to recognize that the current approach to dramatically reducing carbon dioxide emissions is not going to work, even if successful on its own terms.  The sooner we start building that bridge to the future the sooner we can walk across it. It won't be built by targets and timetables for emissions reductions, nor by putting a price on carbon.

The entire NY Times article is worth a read.
