Importing the majority of America’s energy needs is not an option for the next president, says energy and oil expert Byron King. Higher capital costs for nuclear and coal-based energy projects relative to wind, solar and geothermal development will favor these ‘green’ technologies. The possibility of caps on carbon emissions will also weigh heavily on the coal industry.

This from Whiskey and Gunpowder:

I’ve written before that the capital costs for energy projects have swelled in recent years. The costs for key inputs - steel, cement, copper, aluminum, machinery, labor - have outpaced inflation. And it won’t all come to an end just because the Beijing Olympics are over. There’s still a lot of concrete to pour in the Middle Kingdom.

So the world commodity boom will continue its long-term trend upward. And according to the latest data, the costs to build different kinds of power sources have increased dramatically. The relative changes are astonishing, if not sobering.

According to the U.S. Federal Energy Regulatory Commission (FERC), the capital costs of building power generation capacity in the U.S. in 2008 compared with 2003-2004.

The inflationary environment in power generation capital costs has impacted all types of systems. Nuclear has increased the most, because it uses the most steel and concrete. Costs for coal systems have increased quite a bit, as well.

At the same time, the fact is that coal and nuclear generate in excess of 60 percent of the U.S. electricity supply.

And much of the installed base is between 30 to 40 years old, with a significant amount even older. So this installed base of power generation systems is coming to the end of its design life. What will replace it? We had better figure that out now, because it will take the next 20 years (and more) to build the next generation of power systems and plants.

On the other hand, wind power has been affected to a lesser extent by capital cost inflation. Combined cycle and gas turbine combustion still remain cheaper than wind, but wind made up a lot of ground in 2003-2004. These effects will play out over the next few years. These are things that neither the next president nor his policymakers can do anything about. They will just have to ride the wave.

And look at geothermal. It has become more expensive to build out geothermal capacity, but not that much more so. So geothermal is among the most competitive systems out there.

The Chaffee Royalty Program Has Been Re-Opened

For a very brief period, the world famous “Chaffee Royalty Program” is accepting new investors. This is a great opportunity to collect royalty checks for doing virtually nothing.

But you’d better hurry. This program will not be open long. In fact, you only have a few days left. Click here to get in today…

And on the surface, wind appears cheaper to build than geothermal. But that does not take into account that geothermal is far better for baseload power. That is, geothermal can supply power pretty much 24 hours per day, seven days per week. Wind, on the other hand, is limited to times when the wind blows. So it might take, say, three or four separate windmill sites to ensure 24-hour coverage, instead of one geothermal site.

We can only expect that fossil fuel costs will rise over the next few years. Really, who thinks that coal or oil will get cheaper? Rising fuel costs will further damage the economics for fossil-fired power generation, along with rising capital costs.

And despite the relative cost advantage for coal-fired power, the climate change debate is affecting the energy markets. Uncertainty about the future “carbon regime” is a key factor.

There are many questions. That is, will there be a “cap and trade” system on a national or worldwide basis? Both of the major party candidates are discussing this. And cap and trade could manifest itself in many different forms. We might see national limits on carbon emissions. Or there could be taxes on carbon. (British Columbia already has a small tax on carbon. And what happens to small taxes? Yes, of course.)

In addition, the U.S. could enter into any number of treaties that set limits on overall carbon emissions.

What will this do to U.S. industry, both domestic and international? This is no idle musing, either. Large companies like General Electric (NYSE:GE) are making extensive preparations for a future of limitations on burning carbon.

Even now, we are living with the effects of the debate over climate change. The prospect of dramatic carbon regulation has already altered the economics for the coal industry. In the past two years, we have seen numerous cancellations for proposed U.S. coal plants, from Texas to Montana to Pennsylvania to North Carolina.
