I say this a lot on this blog, but I have a hard time believing that it is already August.  My kids are three weeks away from going back to school, people are starting to talk about fall sports, and my mind starts to wander to thoughts of skiing.  Pretty soon the miles on the bike will start to decline and the trips to the weight room will increase.  Gotta’ get the knees ready for big days on the mountain.

On to the links…

Just 10% of Fossil Fuel Subsidy Cash ‘Could Pay for Green Transition’—When someone says that we cannot afford to transition to 100% clean energy what they are really saying is that we are choosing not to afford the transition.  There is more than enough money sloshing around in government and corporate coffers to make a renewable energy world possible.

A Wind Turbine Farm The Size Of Delaware Could Power The Entire United States—Take a look at the map and understand just how much or how little area we are talking about here:

US-map-1.png

Now imagine we actually utilize the offshore wind resources.  Look at how much coastline there is to develop.  We can make this happen.

Low-Carbon Energy Makes Majority of UK Electricity for First Time—This is not a small island being powered by solar.  This is a large island with a post-industrial economy that got over 53% of its electricity in 2018 from low or no carbon power sources.

Coal’s Demise Quickens in Europe as Market Shift Idles Plants—If no one is lining up to buy the power then the plants will sit idle.  The market is working.

Ohio just Passed the Worst Energy Bill of the 21st Century—This is what you get with Republicans in control.  It is crony capitalism at its finest.  Private companies line their pocket with the public’s money with the consent of elected officials.

Angry about No Pay, Kentucky Miners Block Train Loaded with Coal—The coal industry does not care about the people in their employ.  These companies have never treated their employees with anything but contempt at best and deadly intent at worst.  As coal companies go bankrupt they will continue to use the legal and political system to destroy the land and line their pockets at the expense of the communities in which they operate.

Most EV Charging Infrastructure Is Wasted Due To Lack Of New Thinking—It is not that EV charging spots are not numerous enough considering that anyone with a garage or dedicated parking space probably has access to some level of charging.  It is that the charging infrastructure that exists today may not align with how we drive our EVs.

Minnesota Town Makes do Without being Connected to Power Grid—I know that a lot of us imagine living off the grid, but this is what the reality looks like.

Beyond Meat’s Competitor Impossible Foods Plans to Launch in Grocery Stores in September after getting FDA Approval—I am really looking forward to buying a sleeve of Impossible Burgers and throwing them on my own grill this fall.  What I really want to see is Beyond Meat or Impossible Burger selling sleeves of their plant based goodness at Costco.

Plant-Based Eggs Land their First Major Fast Food Deal—Slaughter houses get a bad rap because they are nasty places, but our eggs are also produced in some fairly brutal conditions.  First the plant based substitutes came for our hamburgers, now they are coming for our eggs.  I welcome the transition.

Can Chefs Learn to Love Cooking Without Fire?—Can we just stop our love affair with primal fire?  I get that something about the flame speaks to our lizard brain, but as someone who has cooked with electricity daily for the past twenty years there is no reason to rely on piping explosive gas into our homes to fuel our gastronomic adventures.

Why Republican Baby Boomers are More Likely to Share #fakenews on Facebook—I rag on Baby Boomers pretty hard, but until someone can show me how this generation has actually made the country a better place I am going to keep piling on.

Knocking it Out of the Park with EV Efficiency…Solar Not So Much

There are times when driving my second hand Nissan Leaf feels like I am working on cracking a code.  Change one behavior (e.g. turning on the heat) and relative efficiency takes a nose dive.  Adjust a few things (e.g. make sure to drive with the car set in “B” mode) and it seems like you can do no wrong.  Ambient air temperature, type of driving, route choice…on and on it goes.

I am certain that it is the same for a traditional ICE vehicle or even a Tesla, but when you are limited to a little more than 100 miles on a full charge there is a hyper heightened awareness to how quickly the “guess o’ meter” depletes.  However, it was a lot less of a concern this month as I averaged 6.1 miles per kWh for just a tenth of a mile over 900 miles.  That works out to a little less than 148 kWh of electricity consumed and ~1,053 pounds of carbon dioxide emissions avoided versus driving my truck.

Since January I have driven 4,607 EV miles at an average efficiency of 5.1 miles per kWh.  This correlates to ~5,234 pounds of carbon dioxide emissions avoided versus driving my truck.  As I have said before this assumes that I draw all of my power from the grid as opposed to generating it on site with my solar panels.  Based on gasoline prices I have saved about $650 just in fuel since January.

Speaking of solar photovoltaic production, July was a fairly good month:

720 kWh for the month is good.  It is a little bit less than the same month during the prior year, but I would say that it is within the margin of error.  It is not like this is January and February where snow covered my panels up to a foot deep some times.

All in my household consumption ended up about 26 kWh more than my production.  Included in my household consumption numbers are almost all of my EV charging, so without the Nissan Leaf in the garage we would have ended up over 100 kWh.  Granted, that would mean I was spewing carbon dioxide from the tailpipe of my truck.  I will take the trade.

Unlike some summer months we were home for every weekend and took no trips.  Furthermore, for the entire month of July we went out to eat once.  I feel fairly good about making all but one meal at home, charging my electric car, running the air conditioning when it got really hot, and still managing to almost be even in terms of household electricity consumption versus solar electricity production.  It is my hope that in the next month I will adding about 60% more solar photovoltaic capacity to my roof.

July really walloped us with heat and humidity this week in eastern Iowa.  After a wet and cool May and June, this month came in hot, humid, breezy, and dry.  It is just strange to be talking about high humidity and the soil drying out at the same time.  Yet, here we are.

The Most Important Thing You Can do Right Now to Fight Climate Change, According to Science—The best thing we can do is to keep hammering away at building consensus.

The Biggest Lie in Trump’s Environmental Speech Today—The fact that Ol’ Donnie Two Scoops felt the need to walk up to the podium and deliver a speech about his “environmental leadership” is, perhaps, the most appalling example of the man’s deranged ego run amok.

Tree Planting ‘Has Mind-Blowing Potential’ to Tackle Climate Crisis—Regardless of the degree to which this would be effective in combating climate change the question remains: What is the downside?  We have more forests?

Toilet Paper is Getting Less Sustainable, Researchers Warn—If your toilet paper is not recycled or tree free you are wiping your ass with carbon.  Until you clean up your triple ply, soft as angel wings toilet paper habit you are just destroying forests.

Beverage Companies Embrace Recycling, Until It Costs Them—I live in a state with a longstanding bottle deposit law and every couple of years the beverage industry lines up to try for repeal.  That is how you know it must be working to some degree.  Anything that can unite companies that normally fight like cats and dogs must be some kind of good.

New Wyoming Coal Company Abandons Mines and Miners—Coal companies have always treated workers like crap.  It is now just getting more mainstream coverage.

First Major U.S. Insurance Company Moves Away from Coal—Boring but important notice: If you cannot get insurance a lot of projects cannot get financing.  Financing is the lifeblood of fossil fuel projects.

This Is Exactly Why Clean Coal Is A Joke—There can never be “clean coal.”  Just like there cannot be “safe crystal meth” or “healthy White Castle.”

Herbicide Is What’s for Dinner—Commodity agricultural practices have led us down this path and it is not sustainable.

One-Fifth of Americans are Responsible for Half the Country’s Food-Based Emissions—It’s almost like the 80/20 rule for emissions.  It just goes to show that relatively small changes for a slice of the population can make a big difference in emissions.  Too bad these are also the same people who gobble up “MAGA” hats and loudly proclaim Trump the be the biblical Cryrus.

8 Charts on How Americans Use Air Conditioning—The air conditioning impacts are too damn high!  The fact that almost twenty percent of people set their thermostats below 70 degrees is mind blowing to me.

Second Quarter New Year’s Resolutions Progress

June has come and gone.  Summer is officially here.

It also means that it is a good time to check in on where I am at with my resolutions or goals for 2019.  Here goes:

  • Decarbonize transportation—My 2015 Nissan Leaf has been in the garage for almost six months. Through the end of June 2019 I have driven ~3,706 miles.  By trading a Ford F150 for a Nissan Leaf I have saved ~4,181 pounds of carbon dioxide from being emitted.
  • No more Amazon—While I failed in the first quarter, I feel like I am nailing it in the second quarter with $0—yes, zero—spend at Amazon in the past three months. It is surprisingly hard to resist the temptation to just order something from Amazon at nine in the evening.  It is like our brains are wired to just hit the “add to cart” button.
  • No more Walmart—As with my goal of spending no money at Amazon met with reality in the first quarter but improved in the second quarter, so too did my attempt at not patronizing Walmart. Zero dollars in the second quarter.
  • Read twenty five books—23 down, 2 to go.
  • Drink local—Doing pretty good so far.
  • Declutter my house—I started off with the best intentions in January, but after taking an entire car load of clothes the effort to get stuff out of the house has kind of fizzled. Again, I feel a little overwhelmed by all of the stuff that we have in the house.
  • Replace existing toilets with low volume flush models—I have picked out the model of toilet to replace my existing commodes. Now I just need to get a free day on a weekend to spend a few hours doing some plumbing.  Can you tell that this is my favorite way to spend a few hours on a Saturday?
  • Plant at least five trees—Two Norway spruce trees are in the ground. I am actively hunting for additional trees to plant, but the nursery stock locally has not been very attractive.
  • Reduce lawn coverage— Plans are laid out and some of the hardscaping materials are sitting in my driveway. However, this is the kind project that has to wait until the temperature declines a little bit.  Spending a day digging out turf when the mercury is over 90 degrees and the humidity level is above 90 percent is a no go.
  • Ride 2,500 miles on gravel roads—Almost 1,200 miles have been spent in the saddle so far and this includes a lost week spent on vacation in Colorado. I had the best of intentions to ride while I was out in Summit County, but I chose to hike and raft instead.

So far, so good I think.

June 2019 Solar was Back on Track and EV Miles were Extra Efficient

June was a better month for solar production:

share_image

Over the course of the entire month my household ended up ~150 kWh (consumption minus production), including all of my EV charging for that same period as I did not use any public chargers.  With at least eight more panels being installed on my roof this summer I am going to be seeing a lot more months with excess production.  Every kilowatt hour that I produce from my solar array is like a nail in the coffin for coal.

The excess production in June was a little artificial because we were on the road for more than a week.  With no air conditioning running it is to be expected that we would run a surplus.  June was also fairly cool with a corresponding lack of need to deploy air conditioning.  The last few days of the month were a reminder that summer in Iowa is a hot and sticky affair.  I am talking temperatures exceeding 90 degrees and humidity levels exceeding 90%.  If there was ever a time where I did not want to come home from the mountains this was that time.

For June I drove my Nissan Leaf a total of ~555 miles at an average efficiency of 5.9 miles per kWh.  This is my best number by far, in terms of efficiency, and makes me wonder if I can nurse my way to a figure over 6 miles per kWh in July.  For the period I saved ~646 pounds of C02 being emitted assuming that my charging came via the grid at an average carbon intensity.

You may ask how I can be ahead in terms of energy production yet still account for some level of carbon intensity for my electric vehicle.  Unfortunately, my photovoltaic array’s production occurs when I am not charging my EV which usually happens at night.  Therefore, to run my Nissan Leaf I am utilizing grid electricity.  It’s a little like keeping two sets of books for the same business.

What the actual shit?  This is the Secretary of State of the United States of America telling the public that the solution to climate change is to move to different places. Oh, and the travel time for goods shipped between continents might be slashed because of the lack of sea ice.  I am sure everyone is going to be comforted knowing that their 65” television from China is getting here a little faster as they roast in a climate hellscape.

May Showers Dominate Solar Production and Electric Vehicle Efficiency is Stable

May was a rainy month in eastern Iowa.  How rainy?  It rained for twice the number of hours in May and three times the usual rainfall hit the ground.  Things were really wet.  Like the “ground is a sopping wet sponge” wet.  It had an impact on May’s solar production:

share_image__03_Jun_2019__07-35-25

Now, just over 542 kWh of clean, green solar electricity is not bad.  It is down about 80 kWh from the same month the prior year.

All in all, my household ended up about 10 kWh ahead of consumption for the month of May including home charging of the Nissan Leaf.  When you can drive all month and live in house with modern amenities all powered by the sun that is considered a win.  Sometimes I just feel like I am living in the future.

For the month I drove 937.4 miles in my Nissan Leaf at an average efficiency of 5.5 miles per kilowatt hour.  This beats my efficiency the prior month by 0.1 miles per kilowatt hour.  This saved ~1,080 pounds of carbon dioxide emissions versus my prior vehicle assuming that I charged using grid electricity, which in Iowa averages about 1 pound of CO2 per kWh.  As noted above, I actually ended the month ahead of my consumption so the emission savings were probably higher.

It does not seem like a big win in terms of efficiency.  However, there are two round trips to Iowa City that totaled almost 140 miles of driving at highway speeds.  For anyone who has driven a Nissan Leaf there is a moment of dread the first time that you get the little car up to 60 miles per hour or more and watch your efficiency drop like a stone in freefall.

The trick is to minimize interstate highway type driving in favor of more sedate state or county highway driving.  That is to say, drive 55 miles per hour as opposed to the 70 miles per hour or more on the interstate.  It takes a little longer, sure, but there is something really peaceful cruising along with the windows down and the silence of an electric vehicle drivetrain.

It also helps to have access to public charging at the midpoint of your trip.  In Iowa City there are ChargePoint facilities available in several public parking ramps.  You pay for parking (first hour is free and a $1 per hour for any additional time) and the charging is free as long as you have a ChargePoint account.  My Leaf is equipped with a standard Level 2 charging port so it can accept, at most, 3.3 kWh of electricity per hour of charge.  It is not a lot for the ninety minutes or so that my errands in Iowa City take, but it provides a margin of safety for the trip home that eases any potential range anxiety.

These trips have gotten me thinking about electric vehicles and range.  Maybe the issue is not absolute range, as in 235 miles of range when fully charged, but rather the ability to gain a lot of range in a short period of time, as in 80% battery charge in 30 minutes.  If I was able to regain more than three quarters of my vehicle’s charge in less time than it takes to make a quick trip into Costco that would change my route calculations considerably.  Also, if more public charging facilities were available at destinations that might also change behavior.

Do I spend a little more time in downtown Iowa City because I am charging my Nissan Leaf?  Probably.  Think about that from an economic development standpoint.
