25 Years From Now and Still Relying on Fossil Fuels?

The federal government’s latest international energy projections are out, and there’s no question we’re living in a time of enormous change—and perhaps remarkably little progress.
The International Energy Outlook from the U.S. Energy Information Administration tries to identify the big trends and projections affecting the energy world through 2040. Some of the trends include:
Yet for all that, the EIA projects the world’s overall energy mix won’t change much at all by 2040.
Yes, renewables and nuclear are the fastest-growing sources. But overall, the percent of energy produced by fossil fuels will only drop from 84 percent today to 78 percent in 2040. Renewables only grow from 11 percent to 15 percent, and nuclear rises from 5 percent to 7 percent. Liquid fuels drop by 6 percent, largely because of rising prices. And despite all the debate about the decline of coal and rise of natural gas, the overall percentage of those two fuels barely changes at all. Given that picture, we still be pumping out plenty of greenhouse gases. EIA is predicting a 46 percent increase in global warming emissions during the study’s time frame.
There are important differences in what’s happening in developed nations versus emerging ones. For example, even though the EIA is projecting a small 1 percent drop in the share of coal used by 2040, it expects a dramatic increase in coal consumption between now and 2020, most of it coming from the developing countries that need cheap forms of energy to house and feed their growing populations and to industrialize.
Projections aren’t karmic. They depend on taking current trends and best estimates of what will happen if those trends continue. But it’s a fair question: if there’s so much activity around new energy sources, then why don’t the projections look different? Why don’t the changes have more traction?
The answer may lie in the fact that we haven’t, globally speaking, really reached consensus on the fundamentals: What kind of energy sources should we be using? What economic changes are we willing to make to back up those choices? What are developed nations willing to do to help poorer countries improve their citizens’ lives without depending so heavily on fossil fuels? Those of us living in the developed world have already reaped the benefits of industrialization based on cheap coal. It’s not surprising that developing nations would be tempted to follow the same path—and harder for us to preach to nations that are still building their economies.

The fact is that the changes we’re making on energy are working on the margins, and that’s why the long-term projections only show marginal shifts. If you want big shifts, you have to start making big changes—and that means persuading the public that those changes are worth making.
