So far Ive been talking about our energy problem. But this is incorrect. Because we really have three separate problems, each on its own very difficult to solve. And because the solutions to one will sometimes make the others worse, the overall difficulty is more than additive the whole is greater than the sum of the parts.</p>
<p>The first problem is the projected increase in the use of energy. Unless the world goes into a deep and prolonged recession, by the middle of this century global energy use will likely have doubled, and electricity use will have tripled, placing great pressure on energy supplies and prices.</p>
<p>And in case there is any doubt: whatever role speculators may be playing in the current oil price spike, the underlying issue here is growing demand.</p>
<p>This is an era in which hundreds of millions of people, perhaps even billions, are lifting themselves out of poverty into what we in this country might recognize as at least a way-station on the road to a middle-class standard of living, all within the span of a few decades. This is an economic accomplishment that has no precedent in all of human history, and we should celebrate it.</p>
<p>One of the consequences is sharply increased energy use. But in case anyone thinks that a tripling of electricity demand by mid-century implies irresponsible, profligate consumption, I point out that this would mean, roughly speaking, that the richest billion of the worlds population at that time would be using electricity at about the same rate that the average American uses it today, the middle 7 billion would be using it at a rate that the average Chinese is likely to reach in just a few years (or a bit more than a third of the average Americans usage today), and the poorest billion would still have no electricity at all. That is what a tripling of electricity demand by mid-century will mean.</p>
<p>The second problem is that for at least the next several decades the world will remain heavily dependent on the Persian Gulf for its premium fuels.</p>
<p>More oil and gas will certainly be found and produced in other parts of the world though perhaps not at a rate sufficient to offset the decline in existing fields. In any case these new supplies will generally be more costly, and because of the twist of geological fate which led much of the worlds low-cost oil and gas resources to be deposited in the Gulf region, that volatile area will continue to dominate the global supply picture for the foreseeable future.</p>
<p>**The third problem is of course that of climate change. **This may or may not be the most serious problem of all, but it is certainly the most complex when we consider the scientific, technological, economic and political aspects together as of course we must.</p>
<p>Much has now been learned about this problem, but many major uncertainties remain. So when the question is asked: how fast should we move to try to slow climate change? the answer isnt obvious.</p>
<p>Figuring it out will mean finding a strategy that strikes a balance between the increased economic cost of actions to reduce emissions, on the one hand, and the benefits of those actions (in terms of ecological and economic damage averted in the future), on the other. Unfortunately almost every element in that equation is uncertain. What is certain, though, is that the longer we wait to take action, the more costly the consequences will be. The clock is ticking, and it wont stop ticking simply because we cant or wont decide what to do.</p>
<p>The best chance we have perhaps the only chance --of solving these problems, of breaking out of this triple straitjacket of price, climate, and security pressures, is to accelerate the introduction of new technologies for energy supply and use and deploy them on a very large scale.
