For the first time in forever…sorry, Frozen fans I was just thinking that for the first time in a long time it actually feels like fall.  Within the span of a single work week we have seen the temperatures drop from nearly ninety degrees to nearly freezing overnight.  Welcome to the Midwest during the shoulder season!

On to the links…

The Short List Of Climate Actions That Will Work—It is super easy to explain to people:

  1. Electrify everything
  2. Overbuild renewable energy generation
  3. Integrate electrical transmission across continents
  4. Build hydropower storage systems
  5. Plant a lot of trees
  6. Reform agriculture to capture carbon in the soil

And so on.  None of these actions is hard to grasp or hard to implement.  It just takes political will.

Solar, Wind Are Now Cheaper Than Coal In Most Of The World—The battle has been won.  To win the war we must keep pressing forward.

World’s Largest Wind Turbines to be Built off Yorkshire Coast—It is hard to grasp the scale.  A single turbine producing enough electricity to power 16,000 homes.  Wow.  This is why the UK is transitioning away from coal.

McCharge? Yes, McDonald’s Wants To Charge Your EV—One of the goals of any convenience type purchase—food, gasoline, coffee, etc.—is to increase the number of trips you make to the location.  The more trips a person makes increases the potential that the person will spend more money.  If you could spend thirty minutes on a DC fast charger at McDonald’s while wolfing down a Big Mac it might make you stop.

Volta’s EV Network Gives You 30 Minutes of Free Fast Charging—Think about this as an amenity that draws traffic.  If you have an EV and can get thirty minutes of high voltage charging would you be more likely to stop at that retail location over another?  Probably.

First Gas Station in America to Ditch Oil for 100% Electric Vehicle Charging Opens in Maryland—Someone had to be first.  However, given that EV charging does not require expensive underground storage tanks for a flammable liquid like traditional gas stations I have to imagine that the old model of gas stations is a dinosaur.

Here Is Why Electrification Of Medium/Heavy Trucks Is Important—Representing just 4% of vehicles these trucks are responsible for 9% of vehicle miles traveled and 26% of fuel gallons consumed:

Vehicle Population, VMT, and Fuel Use by Vehicle Class, 2017 Source energy.gov.png

Anheuser-Busch To Deploy 21 BYD Electric Trucks In California—The truck that is delivering those cases of Natty Light may now be an EV.

If Everyone Ate Beans Instead of Beef—One change, half of our greenhouse gas emissions reduction goal.  Simple.

That Viral Study About Red Meat Left Out The Most Important Part—Climate change is the greatest risk to our collective health.  Ignoring its potential impacts when considering the climate change impacts of red meat production is like trying to quantify the opioid epidemic without looking at heroin use.

Amid Rising Demand for Beyond Meat Burgers, U.S. Farmers Can’t Solve This Supply Problem—It has not even been a complete growing season in North America since Beyond Meat went public and meat substitutes became a thing in the United States.

Germany Makes a National Commitment to Rescue Its Forests—There is a massive amount of climate change mitigation potential waiting to be exercised in rebuilding our stocks of forested lands.  As rain forests in South America and Indonesia burn as a result of bad policy it is more important than ever to rethink our relationship to the forests in our collective backyards.

Los Angeles, a City Known for Its Freeways, Is About to Plant a Shit Ton of Trees—I do not know if it is actually a “shit ton” of trees, but it is a start.  Now imagine communities across the United States and the world for that matter doing the same thing.  It is possible.

The Story of The Largest Private Land Donation In History and Creation of Patagonia National Park—Just take a few minutes out of your day and watch this video.  Also, imagine a world where the uber rich like Jeff Bezos and Mark Zuckerberg spent money on truly bold conservation efforts.

What Would It Be Like to Live in an Era of Geoengineering?—Is it our fate to live on a planet where we have knowingly changed the natural systems to counteract our own collective stupidity?  God I hope not.

Third Quarter New Year’s Resolutions Progress

It is now October and that means it is fall.  It also means that I am nine months of the way through the year which is probably 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 nine months. Through the end of September 2019 I have driven ~5,893 miles.  By trading a Ford F150 for a Nissan Leaf I have saved ~6,733 pounds of carbon dioxide from being emitted.
  • No more Amazon—While I failed in the first quarter and succeeded in the second quarter, the third quarter was a little better. I spent some money that I was “awarded” from work via a gift card.  It was money spent at Amazon, but it was not my cash and I felt that the effort to transfer the funds was not worth the return.  Trying to reduce my spending at both Amazon and Walmart has made me think about our consumer habits in general.  More to come.
  • No more Walmart—Spent about a $100 on school supplies for a work organized effort to help out area kids during the back to school time. Walmart was running sales where I was able to pick up whole classrooms’ worth of some supplies for a few dollars.  It was craziness and well worth failing in my goal to make it happen.
  • Read twenty five books—38 books read in the first nine months.  Mission accomplished.
  • Drink local—Doing pretty good so far.
  • Declutter my house—This is probably the singular failure so far this year. Sure, some stuff has gone to Goodwill but I feel that on the whole nothing is less cluttered than it was nine months ago.  Maybe I can sprint to the finish.
  • Replace existing toilets with low volume flush models—I have picked out the model of toilet to replace my existing commodes. I have even purchased the wax rings to install the new toilers.  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. Three Colorado blue spruce trees in the ground.  Mission accomplished.
  • Reduce lawn coverage— No real progress, but I have plans. I promise!
  • Ride 2,500 miles on gravel roads—I am sitting at ~2,718 miles for the season as the month of September came to a close. Surprisingly, September was a real dog of a month for riding as the weather really conspired to keep me inside.   Mission accomplished.

So far, so good I think.

September 2019 Solar PV and EV Numbers

The past month was surprisingly similar to the same month the year prior:

Sept 2019 solar

Almost 416 kWh of clean, green electricity from the funky yellow sun.  All in, including 100% of my EV charging needs, I ended up down ~122 kWh for the month.  The weather was schizophrenic this month bouncing from cool fall weather to hot and humid.  The third week of the month felt like the dog days of August with 90 degree temperature readings and similar humidity levels.  Needless to say, the air conditioning got turned on to cut that down a little bit.  Until that point I was running ahead in terms of production versus consumption.

For the month I drove my Nissan Leaf EV 755.1 miles with an average efficiency of 5.9 miles per kWh.  For the month I required ~128 kWh of electricity for my mobility.  Compared with the F150 that the Leaf replaced, I avoided emitting ~879 pounds of CO2 into the atmosphere assuming that I drew electricity from the grid at an average carbon intensity for my region.

For the first nine months or so of the year—my Leaf arrived the second week of January—I have driven a total of 5,893 electric miles at an average efficiency of 5.2 miles per kWh.  The total C02 emissions that have been avoided versus the F150 that the Leaf replaced are 6,733 pounds thus far.  Again, this assumes 100% of charging occurs from the grid with an average carbon intensity for the region.

Interestingly, the total amount to charge my Nissan Leaf for the month–~128 kWh—was about how much I was “down” for the month in terms of solar production.  This aligns with my original estimates where my initial sixteen panel PV array would provide ~100% of my electricity needs.

As the weather turns cool and the pumpkin spice flows freely I am waiting on an install date for the solar array expansion.  The plan is to add 8 360 watt panels to my existing 16 290 watt panel array.  This represents a ~59% increase in solar capacity and given the new panels will be on the same azimuth it should represent the same amount of increase in terms of actual production.

The increase in solar array capacity should account for more than 100% of my Leaf’s charging needs and provide a cushion of excess production for additional electrification.  The future is electric.

I know it has been almost two weeks, but this is my favorite animated GIF ever:

Every time I hear a fan of Iowa State University say, “We just beat ourselves,” I just think, “No shit, you really did.”

On to the links…

Good News, Bad News: 4 Trends in US Energy Use—Transportation energy use and, by extension, oil consumption are the great hurdle for our transition to a fossil free paradigm.  However, I wonder just how much we could reduce our use of energy in the transportation sector by reduction rather than replacement of usage?

Coal Declining at Quicker Clip than Previously Forecast—Every solar panel that gets hooked up to the grid is a nail in the coffin of coal.  That is what I think about every time I imagine what eight additional panels added to my array mean in the larger scheme of things.

Are 1,600 New Coal-Fired Power Plants Being Constructed Today?—The brief answer is no.  Now that this story has been debunked thoroughly it will probably make it into the next round of Trump rallies.

How Hawaii has Built Momentum to Become a Renewable Energy Leader—Hawaii is our national laboratory for renewable energy.  The state is on course to produce 40% of its energy from renewable sources fairly soon.  We need to be looking to Hawaii and applying lessons learned across the United States.

Solar and Wind Power So Cheap They’re Outgrowing Subsidies—Now, let’s remove the subsidies from fossil fuels and see how things work out.

Residential Solar: Becoming Increasingly Cost-Effective And Customer-Friendly—The market is maturing, transparency is increasing, costs are coming down, and adoption is up.  These are the trends that make something mainstream.  Solar is mainstream.

Getting to 100% Renewables Requires Cheap Energy Storage. But How Cheap?—I think the question is not just the price, but also how much capacity is really required?  We have seen that as states and countries build out renewable energy that the hurdles are less insurmountable than they appeared at first blush.

Is DC Fast Charging Bad For Your Electric Car?—Yes, but not as bad as some pundits would have you believe.

The Rise of Regenerative Agriculture in Colorado—It is not just about saving pristine places anymore.  It is also about restoring the places that we have degraded.  Agriculture can play a role in that restoration.

The Burger Brawl—Do I really care who wins as long as these products replace traditional burgers?

1% of English Residents Take One-Fifth of Overseas Flights—Amazing how it looks like the Pareto principle is at work here.  One percent responsible for 20%, top ten percent responsible for more than 50%…

What Do Evangelical Christians Really Think About Climate Change?—Given that this is a group of people—I am making broad assumptions here—that support Donald Trump despite his blatant non-Christian behavior after years of telling people that they were “values voters” I am inclined to tell evangelical Christians to suck a big, fat one.

This is What the Future Looks Like

People frequently ask me what I think the future looks like.  Rarely do I provide a coherent answer because what I think will happen is constantly changing based on the conditions of the day.  There do exist some constants, however, and solar power is one of those constants.

Why?  For one, it is easy.  Once the panels are installed your array will just sit on your roof producing electricity regardless of what you do.  When you go to work the panels produce electricity.  When you go on vacation the panels produce electricity.  It is the ultimate in “set it and forget it” environmentally beneficial behaviors.

Second, you can see the impact at a household level.  If my utility purchased electricity produced by wind turbines I have no real concept of what that means to me.  Was 15% of my electricity produced by the wind?  More?  Less?  However, with solar panels installed you get a very local idea of how much energy you have produced versus how much you have consumed.  Witness this portion of my latest utility bill:

Electricity Usage House September.png

Notice the lack of green bars from April through August?  That signifies my solar array produced all or more of the electricity that I consumed during that period.  Sometimes my math and the utility company’s math will not align because billing periods do not align with calendar months but the general outlines agree.

Now, imagine approximately 60% more solar photovoltaic capacity being added to this chart.  The contract has been signed, the check has been sent, the plans have been approved, and the panels are waiting in a local warehouse for my system expansion.  I am just waiting to hear when the installers are scheduled to make it happen.

This is what the future looks like.

If you have a Sharpie and you are the President of the United States then anything is possible:

MW-HQ712_trumpm_20190904181037_ZH.jpg

It is an old trope to ask someone what the right wing would have said or done in the wake of President Obama doing the same thing, but can you imagine the cerebral hemorrhage that Sean Hannity would have had in this case?

We live in strange times.

On to the links…

15 Things a President can Actually do to Tackle the Climate Crisis—It’s not like number fifteen on this list is ever going to happen.

Cedar Rapids Electric Bill Could be Slashed in Half from New LED Lighting in Downtown—It’s a small change, but why hasn’t every city in America switched to LED streetlights?

Trump Rolls Back Regulations on Energy-Saving Lightbulbs—Does Donald Trump just sit in his private residence during “executive time” and mumble things like, “LEDs…bad…horrible…old, hot lights…good.”  In a little more than one year and four months someone with half a brain can take the executive pen and reassert some sanity.

Economics of Electric Vehicles Mean Oil’s Days As A Transport Fuel Are Numbered—Anyone who drives an electric vehicle will agree with this hypothesis.  In my case, I spend approximately 2 cents per mile to drive my Nissan Leaf versus approximately 15 cents per mile to drive my Ford F150.  Even if I doubled the mileage of my truck it could not compete.

China’s Very Ambitious Transportation Revolution—China was supposed to be the “swing” consumer for fossil fuels as developed Western economies transitioned to cleaner energy.  Looks like China is going to try and just bypass the whole dependency on fossil fuels stage of economic development.

While ‘Zombie’ Mines Idle, Cleanup and Workers Suffer in Limbo—Coal companies do not care about workers or the communities that they leave behind when they close up shop.  Coal executives fly away on private jets after paying themselves while leaving workers high and dry.

The Feds Tried to Make an Example of a small Washington Coal Mine. It Didn’t Work.—Twenty years later and the job is still not done.  Maybe it would be best if we just left the coal in the ground and found another way to make electricity.

Ireland Will Plant 440 Million Trees By 2040 To Combat Climate Change—If Ireland can plant 440 million trees in a little more than twenty years what could the United States achieve?  Okay, probably nothing in the short term with Republicans and Donald Trump hanging around.

The Disturbing Hypothesis for the Sudden Uptick in Chronic Kidney Disease—Climate change will come for our chocolate and coffee.  Climate change is also coming for our kidneys.

Holy Cross Energy Eyes Complete Decarbonization after Striking New Wind Energy Deal—Big utilities, small utilities, rural electric cooperatives…the list goes on and on but the trend is the same.  The tools to free our electricity production from the tyranny of fossil fuels are available and cost competitive.

The Best Place for Harvesting Solar Energy Is Not Where I Expected It to Be—I remember reading about a French pilot project that combined solar canopies over high value crops like grapes.  That project showed the viability of the idea.

One Very Bad Habit Is Fueling the Global Recycling Meltdown—I see this all the time in my neighborhood where people put all kinds of random crap in the curbside recycling bins.  Styrofoam packaging?  Yep.  Resin chairs?  Yep.  Christmas light strings?  Yep.

Banning Mini Shampoos from Hotels Won’t Really Reduce Plastic or Save the Environment—We are just nibbling around the edges of our problems with promises like these.

Tyson Foods Invests in Plant-Based Shrimp Company—I do not know if plant based shrimp is any good, but I know that plant based foods are a real trend when the people at Tyson Foods are putting their money behind the trend.

A Great Month for Solar Production, Electricity Consumption, and EV Efficiency

At last!  In August 2019 my solar photovoltaic array produced more than the same month in prior years.  I was somewhat consigned to a reality where my best days of solar production were behind me, but August came to the rescue:

Image-1 (4)

All in, my household ended up 179 kWh “up” in terms of electricity production minus consumption.  Remember, this includes all of my EV miles as well.  For the year I am creeping back toward being even in terms of production minus consumption after some awful months in the dead of winter.  During that period of time my solar array was covered in nearly a foot of wind driven snow and our electricity usage was high due to crazy low temperatures.  Normally August is a heavy month for air conditioning use.  Our HVAC system has been idle since the first week of month.

For the month of August my total miles driven in the Nissan Leaf was depressed by not being home for a little more than a week.  In the end I drove 531.2 miles at an average efficiency of 6 miles per kWh.  Compared to my truck and assuming power is drawn from the electricity grid, I saved ~620 pounds of carbon dioxide from entering the atmosphere.

Since bringing the Nissan Leaf home I have driven a total of 5,138 miles and save 5,854 pounds of carbon dioxide from being released.  Using the most conservative method of calculating savings—which assumes all electricity comes from the grid as opposed to my solar panels—I have saved just under $727 in fuel costs alone.
