The clunky, lagging transition to renewable energy
History suggests that it can take up to 50 years to replace an existing energy infrastructure, and we don't have that long, Cobb writes.

As for heat for buildings, certainly we could insulate and seal our existing buildings better. And, this points the way to achieving an energy transition within the time we need to achieve it. Since it will probably be impossible to scale renewable energy fast enough to a level sufficient to produce the amount of energy we use today, the one absolute necessity to a successful energy transition is reducing consumption drastically. No politician dares to say anything remotely approaching this. And yet, it would be the cheapest, fastest way to address the twin crises of fossil fuel depletion and climate change.Skip to next paragraph

Now, when I say reduce, I mean on the order of 80 percent over the next 20 to 30 years. For Americans this may seem impossible until they contemplate that the average European lives on half the energy of the average American. So often we hope for technological breakthroughs that will give us all the clean energy we desire. But we ought to focus equally, if not more, on using our prowess to find ways to reduce our energy consumption drastically. This is actually the much easier road. When we are made conscious of our energy use, we can change our behavior quickly to modify it without compromising the quality of our lives. As more homes and businesses are given the means to monitor their energy use, the people in them will change to lower their consumption and costs.
Already we know how to build so-called passive design structures which can lower energy use by 80 percent. And, we desperately need to figure out how to apply these techniques cheaply and economically to existinghomes and businesses. In transportation we need to stop thinking that cars equal transportation and instead realize that cars provide the service of transportation which can be obtained in a number of ways, many of which use much less energy.
We may also need to speed the energy transition in electric power generation using so-called feed-in tariffs. These tariffs--which harness the ingenuity of countless small producers--have enabled Germany to expand solar, wind and other alternatives so that they generate 25 percent of its electricity today. Germany, not a particularly sunny place, is currently the world's top generator of solar electricity.
Of course, per person energy consumption in poor countries is only a small fraction of that in rich countries. We cannot expect the world's poor to reduce their energy use by 80 percent. Instead, we must help them to move quickly beyond fossil fuels to renewable energy.
By simultaneously reducing consumption and encouraging a rapid buildout of renewable energy, it is possible that we could mitigate the problem of declining fossil fuel supplies before it becomes so acute that it would cripple that very buildout. And, we could address climate change at the same time. Certainly, there are difficult problems to be solved with renewable energy, storage being the key one. Most renewable energy comes in the form of electricity, and since there is often a mismatch between the time we produce that electricity and the time we need it, we will have to master storage.
But we will need a lot less storage if we focus on reducing consumption. This is the one strategy which will allow us to overcome the rate-of-conversion problem and achieve an energy transition in far less time than we have in the past.
