Peter Calthorpe – Urbanism in the Age of Climate Change

2

Last week I saw Peter Calthorpe speak about his new book, Urbanism in the Age of Climate Change.

A highly influential planner, designer and urban thinker, Calthorpe has spent decades advancing holistic approaches to the built environment, most famously as a champion of  New Urbanism.

His latest book lays out the case that urbanism, i.e., creating more dense and livable cities, is the only real defense against climate change. If climate change is hastened by runaway carbon emissions, and carbon emissions are linked to the energy intensity of daily life, then it follows that altering the built environment and transportation patterns are key to its mitigation.

This may not be news to anyone, but Calthorpe’s book is about skillfully unpacking this data for a non-technical audience and showing how sprawl is not just a little more carbon intensive than denser urban development, but more intensive by orders of magnitude. Read it for a study of “the big picture”.

California’s Clean Energy Future, Part 1

3

On Tuesday, January 25, I was in the audience at the SPUR Urban Center in San Francisco as Panama Bartholomy, California Energy Commission (CEC), and Emma Wendt, PG&E, gave presentation about California’s clean energy future.

The post below consists of Part 1 of my record of the presentation – the first part of Panama Bartholomy’s presentation. All portions are included in chronological order.

An ellipsis (…) indicates that I was not able to capture the words or thoughts skipped. The presentation is transcribed as accurately as possible – punctuation choices are mine. I also added any photos or images.

The speakers were introduced by Raphael Sperry and Geoff Danker.

Panama Bartholomy

I’m honored to be here… Obviously, I’m a bureaucrat. All my life I’ve wanted to be a bureaucrat. It’s true… … So I have achieved my dreams – I work for the state of California… I am here to talk about what I hope are some of our shared goals… building a  future that’s healthy for our economy, our environment, and our communities… …

I was supposed to talk about, and will talk about, California’s Clean Energy Future…  big ambitious goals. A massive document describes the process of how we’re all going to reach these goals… and how the agencies are going to work on it. In brief, it outlines very ambitious energy goals. It calls for zero net energy buildings… ways to shave peak demand… want to build carbon capture and storage in California by 2020… also want 1 million electric vehicles in California by 2020. So these are the goals. So I’m going to talk about the programs and activities behind the goals to make them a reality…

… … …

I have to give some background, then talk about efficiency…  then major market barriers around energy efficiency and what’s stopping a strong retrofit market, then renewables. Finally, I’ll talk about what’s coming from the Brown administration… …

So some energy context… I’m only going to talk about electricity and natural gas… One of the jobs of the CEC is to measure energy demand and project demand into the future… [looking at a chart] Here, you can see impacts of downturns in the economy… We’re expecting that the economy will pick up later this year or early next, then we will see about 1.2% growth in demand a year. Much of that is from the building sector… We expect to see continued increases in demand, especially from the commercial and residential sectors.

So we have several options. Do nothing. Then we get demand exceeding supply. Or we can build power plants. Or we can find ways to reduce demand… Efficiency is by far our most cost-effective choice in terms of how to meet demand.

Going back to natural gas… California only produces 13% percent of our own natural gas – the rest comes from other areas. We are at the end of the line when it comes to natural gas delivery. We are starting to compete more and more with Nevada, Arizona and New Mexico… …

Overarching a lot of activity on energy efficiency, I have to talk about California’s new climate policy… … AB 32 calls for us to reduce our economy-wide emissions levels to 1990 levels by 2020. This is about a 25-30% reduction in GHG emissions… The big player is transportation. Also, we have to look at electricity generation. The 1/4 of our electricity that we import is equal in GHG emissions to the 3/4 that we produce in-state. The built environment is the second largest wedge when we add the bits together. The built environment dictates how we need to get around, so it has a big impact… We have some work to do…
