Is California About to Require that by 2045 All Electricity Must Come from Renewables?

Image
Not exactly. Let me explain. Our lack of even the most basic understanding of how the elecricity system operates (explained below) allows us to mistakenly imagine we are taking actions that will shut down CO2 emitting generators. A number of headlines read something like "California Poised To Require All Its Electricity To Come From Renewables."  SB100  appears to be a bit more complicated, however.  Plus, electricity complies to the laws of physics, not the laws we mere mortals devise. Hoefully, this post will identify several important implications of these distinctions. Recognize that electrons (what electricity consists of) going over the wires thorughout California flow from all generators located everywhere within what’s called the Western Interconnect (WECC).  Electrons are already present throughout all the electric wires in every building in every community at every moment in time. When you flip a light switch on, more electricity gets generated ...

100% Renewables Study Implies Historic Construction Program

Image
The often cited study by Mark Jacobson et. al. that asserts it's economic to replace every fossil fuel use with either electricity from wind, water, and sun (WWS-only) or hydrogen produced using WWS-only in 139 countries over the next 33 years implies a massive construction program the likes of which we may not have ever seen. I find it useful to compare the implied construction program to what we have experienced in the recent past. Click  here  to see his paper on the 50 U.S. states. Over the next 33 years, even under his extraordinary drop in total electric load, he envisions approximately 5.8 million MW of new generation are needed (plus an additional 600GW for peaking and system stability). He reports that as of 2013, 2.71% (of 5.8 million MW) is currently installed, or approximately1.6 million MW. Such quantities indicate an extraordinary construction program, especially since the U.S. installed capacity rose by only about 177,400MWs over the eight year pe...

Oregon PUC Declines to Support PGE's Proposed Wind Resource

Image
Last Tuesday, the OPUC Commissioners held a regularly scheduled hearing. The main topic was Portland General Electric's (PGE) proposed acquisition of 175 aMW of wind. At the hearing, which I attended, renewable and environmental advocates were out in force. Dozens of citizens showed up wearing read t-shirts, some with 350.org, others from the Sierra Club. Others wore the color red in solidarity. Commissioner Bloom, the lone Republican on the three-member Commission, read prepared remarks that were extraordinary, being delivered from the Dias. He chastised PGE for an op-ed in the Oregonian the prior Friday in which the Company's head honchos essentially pleded with the public to come to help support their proposed acquisition before the Commission. I've seen the Commissioners take witnesses to task. What I hadn't seen was a thorough admonishment of a utility at the beginning of a hearing, reading from prepared remarks. Customer groups had filed testimony opposing P...

Recently, a friend sent me a copy of Bakke’s book, The Grid.  Two days ago, after getting a draft journal article off my desk, I took it off my stack and cracked its cover.  My hope is that the remainder of it is as good as its introduction and first chapter.  It's quite an accomplishment; and a very well written one.  She quickly gets to the heart of the challenge posed by integrating intermittent renewables (a tautology, once hydro is excluded) on p. 13.  She writes ”Power production isn’t just an industry, it’s an ecology.  And renewable resources are not just about the planetary good kept from public offer by corporations with other visions for their own profitable futures.  Making American power is about how technological, biological, and cultural systems work in concert to keep our lights on, our basements and roadways clear of flood water, and fresh fish on our tables. It’s delicate in all sorts of ways….it does the reader well to remember tha...

Buying Locally Made Helps The Environment

Image
What's the significance of buying products made outside Oregon or outside the U.S.? Certainly, there are many reasons why we might care about where - and how - the stuff we buy is made. What I'm interested in is how total CO2 equivalent (CO2e) of goods purchased by Oregonians changes as the locus of production changes.  For 2005, CO2e emissions from consumption of goods and services by Oregonians resulted in 56.7 MMT CO2e (note that some but not all the goods purchased were from within Oregon). If Oregonians purchased the exact same goods and services but they were all made outside of Oregon, those emissions would climb to 67.7 MMT CO2e. If instead of buying U.S. made products, Oregonians purchased that same bsdket of goods  all made outside the U.S., total CO2e emissions jump to 113.5 MMT.
