First EV Savings Milestone

Welcome to anotherĀ Tesla Tuesday!

I’ve mentioned before that I’m pulling in a lot of car stats with TeslaMate. I’m also using the GasBuddy API to record the prices at the six gas stations closest to my house. This lets me calculate how much I would be spending on gas if I drove the exact same distances at the same time. I assume that I would fill up every day which isn’t accurate, but over time, it should be nearly spot on.

I take all that gas price data and compare it against the cost for every charge I’ve put into the car. Most of the charging is done at home (92%), but if I’m on the road, I have all those prices as well too.

So if I compare my actual charging costs versus the estimate gas prices for the same driving pattern, we have saved our first $1000! Despite the high entry price, we bought this car because I believe it will be cheaper than if we bought another Escape. Using my conservative estimates and the lower gas prices from last summer, I expected to save $1000 every ~8000 miles, but we hit the first $1000 of savings at 5800 miles.

Digging into those charging costs at home a bit more, here’s a chart for our electric usage for the last 11 years:

You can see where we got the new car at the end of the chart, and our monthly usage can vary quite a bit based on how much we drive. Do you see that spike back in January 2014? That winter we tried running a space heater in one room. I cut that off quickly after monitoring how much power it used. The space heater wasn’t cheaper than just turning up the furnace a bit more. So if you’re nervous about the additional cost of charging an EV at home, look around your house at those space heaters. If you have one or two of them running, that’s roughly the same as charging an EV (caveat caveat caveat but they can be in the same ballpark.)

Gas savings alone won’t make this car cheaper. I’m also counting on lower total service bills (no oil changes, less moving parts to fail, etc) and a higher resale value. We won’t know how all that plays out for many years, but it’s fun to see it working out better than planned so far!

Disc Golf Newbies

The new craze in our house is disc golf. I asked for a cheap starter pack of discs for Father’s Day, and all three of us enjoyed it the very first time we went out. There are about half a dozen free courses within a 30 minute drive and the closest one is only 5 minutes away.

I was a bit nervous/embarrassed the first time we went out, but I’ve found the disc golf crowd to be extremely friendly and welcoming. Plus, we quickly learned that lots of people are just out there having family fun and we weren’t as slow or bad as we thought. Course etiquette is very similar to golf so I was able to work on those social norms with Elijah first and then we started learning more about the game.

YouTube is a great resource for learning disc golf and it helped us understand the basic form, the flow of play, special rules, etc. While there are people who are extremely good at the sport, I’ve found it to be very accessible for inexperienced players. You can go out there knowing nothing and have a blast. And while it would take a huge amount of time to master the sport, you can find bits success early on. For example, only about 10 rounds into the sport, we’ve all made a par and I was a few inches off from a hole-in-one. You can pick up a starter set of discs for around $30, and as I mentioned, many of the courses are free. The UDisc app is a great way to find nearby courses and keep score.

It’s fun to discover a new activity where I can compete against myself, play for basically free, and see myself rapidly improve since I went in knowing nothing! If you’re in the area, I’d be happy to share some discs with you and show you what it’s like. At the very least, you get to enjoy walking around in a park for an hour.

Streaming Packages

For our TV watching, we almost exclusively use streaming service. We do have an antenna set up for some locals with a DVR hooked up to it, but that’s only used for some Seahawks games. We always have Amazon Prime Video since that comes with our Amazon Prime subscription, and we pay for YouTube with no ads, but otherwise, we rotate our services so that we only pay for one other one at a time.

That’s the goal but it doesn’t always play out that way. For the past few years, we’ve had Disney Plus. In November of 2019, we did a three year pre-paid deal which came out to less than $4/month. That is expiring in a couple months so it has me looking at streaming service prices in more detail. Netflix is expensive but it’s a single service so it’s easy to add and drop. The complexity comes with Disney Plus and Hulu. Those prices are all going up by a few bucks on October 10. They make it tricky because they offer a bundle of Disney Plus, Hulu, and ESPN Plus that is less a pretty good deal if you’re ever going to have two of those services.

  • Hulu $14.99/month
  • Disney+ $10.99/month
  • ESPN+ $9.99/month
  • Bundle all three for $20.99/month

I don’t know that we’d ever watch ESPN+ but it’s hard to decide if we’ll do monthly Hulu and Disney+ alternating individually or get the bundle. (Those prices are for the services without ads. I will pay to avoid ads anywhere possible.)

The nice thing is that these decisions are low cost and effort. It’s so easy to subscribe and unsubscribe from month to month. I’ll frequently hit unsubscribe on whatever service we have an see how long it takes us to notice that it died off. Otherwise, it’s easy for the costs to pile up quickly and silently.

Dege Peak Hike

We signed our fourth grader up for his free National Park Pass as soon as he was eligible, and we’ve already put it to use! Last weekend we headed to Mt. Rainier for a hike up Dege Peak.

The trip almost didn’t happen though. There was a lot of smoke in the area from wildfires burning east of the Cascades, but based on the webcams at Rainier and Crystal, I thought we’d be mostly above the smoke. Then there was the wind. I was not expecting it to be so windy down there, but when we hit Enumclaw, we were greeted by ~30mph winds. And finally, anytime I visit Rainier on a weekend, I wonder what the crowds will be like. We hit the tool booth on the way up to Sunrise at 9:21 and only waited 7 minutes to get through.

As I had hoped, the smoke was thinning as we pulled into a parking spot at the visitor center. We hit the bathrooms, applied sunscreen (which was very eager to come out of the bottle with the elevation pressure change!), and set out on the hike to Dege Peak.

The trail itself isn’t anything to write home about. There’s a bit of elevation gain at the beginning and the end, but otherwise it’s a straight dusty trail along a ridge. The incredible views are what make it a winner. Heading to the peak, Rainier is at your back, but there are still magnificent views to both sides, and it would have been even better without the smoke. Coming back, Rainier is always in your face. I had to consciously pay attention to the trail because walking while staring at the mountain is a combo built for tripping.

We didn’t stay on the peak very long because the wind was so intense. Elijah was nervous he was going to get blown off, and while that’s an exaggeration, we were all holding onto our hats, and we had our snack somewhere else. There’s not a lot of room up there, but the high winds kept people from loitering too long and we got our fill of the unobstructed view.

There are so many other hikes that I’d love to do down at Rainier. It’s a wonderful gift to have that national park within a two-hour drive of our house!

Woodworking Instagram Reborn

As mentioned previously, I lost control of my @martenswoodshop Instagram account. Since then, I’ve realized that I really do like having a single place that can easily function as a portfolio of my work. “Oh you build stuff? What do you like to make?” It’s a lot easier when I can just send a simple URL. And it’s also good motivation for me when I look and see how long it has been since my last project post. It makes me want to get out and do more!

So if you’re at all interested in this kind of thing, please follow @martenswoodworks. I reposted some of my projects to that account and I’ll be posting more going forward. I’m wrapping up a project soon that involves 3D carving on the CNC!

Mountainous Tesla Trips

Welcome to anotherĀ Tesla Tuesday!

We took the Tesla on our trip to the Sunrise Visitor Center at Mt. Rainier (200 miles round trip). Before the trip, I had used abetterrouteplanner.com to check how the charging would work out. I’ve done a bit of work on that site to tweak the settings to pretty accurately match our real-world behavior and it said that if I left home with 90% charge, we’d hit the visitor center with 45% and we’d get back home with a comfortable 24%. I didn’t think much more about it

When we got in our car to leave, I punched the route into the car and it said that I would get to Sunrise with only 28% charge but then we’d get home with 10%. I knew that we had to gain a lot of elevation going up to 6400 feet at the visitor center, but those numbers seemed wild and since I’ve had experience with those estimates being pretty far off in the mountains, I was a bit nervous. But we went for it anyway.

My battery concerns were further fanned by ~30mph headwinds once we reached Enumclaw. That sucks energy too, but how much? The car was still confident that we’d make it back home fine, and I knew there were enough superchargers along the way to use as a fallback if needed. In the end,

Sure enough, the climb up to the visitor center did take a lot of battery, but not nearly as much as the car had originally estimated. We arrived with 44% battery remaining, only 1% off from what abetterrouteplanner.com had estimated! I guess if the Tesla estimate had to be off, I would prefer for it to be pessimistic like this, but that’s so far off that it feels unhelpful. (Note that the trip shown in the image is only the distance from Enumclaw to Sunrise because we had a bathroom stop.)

The green line is actual usage and the gray line is estimated usage.

I’ll have a separate post about the hike, but after the hike, we headed back down the mountain. In a normal car, the best you can hope for is that your car smartly uses engine braking to generate enough power to run the AC, radio, lights, etc and you use no gas when you go down the mountain. In an EV, the story is even better. Not only is it running all of those things for free, but it’s also storing up all the extra energy that it doesn’t need right away. On the 16 miles down from Sunrise back to Hwy 410, we charged back up to 47%. We then proceeded to use that extra energy to drive an additional ~30 miles before we were back at 43% charge. So yes, we used more battery going up the mountain, but then we drove for 50 miles from the top for free!

This shows how much energy was consumed driving up and then coming down.

At the end of the day, we averaged 227 Wh/mi for the trip. We average 250-265 on a normal long trip so I don’t know if the lower usage on this was due to something with the mountain, changing winds, or the fact that most of the roads on this route were 50mph speed limits instead of 60-70 on the highway.

I’m continuing to learn more about what to expect from the car, and each time we do a trip like this, it makes me more and more comfortable exploring the limits of our range.

Free National Park Pass For Fourth Graders

If you have a fourth grader, they are entitled to a one-year free national park pass which is an $80 value. (“Free” as in pre-paid with your federal taxes whether you use it or now.) Head over to https://everykidoutdoors.gov and fill out a quick form with them. You’ll print off a pass that you can use for free entry not just for the kid but for everyone in the car. There are of course some limits on the number of people it covers, etc but for our family, it will cover pretty much all situations that we’ll encounter. These passes are valid every year from Sept 1 through Aug 31 so now is the time to jump on this if you have a fourth grader in the house or set a reminder on your calendar if you have a younger child.

Leaping Lamb Farm Stay

Leading up to our 40th birthdays, we decided to do something a little bigger than we normally do. Mine happened in 2020 right after COVID hit so my list of ideas got wiped out, but I’m happy with my lifetime membership to an area taproom. Tyla’s birthday was this year, so she had a few more options and ended up deciding on a few nights at Leaping Lamb Farm in Alsea, OR.

I feel like you never really know what you’re getting with these kinds of places. How much do you get to interact with the animals? How much freedom do you have to roam? Are the people that work there nice or just busy to move on to their next task? We hit the jackpot with this place.

There are two rental houses on the property. One is a giant farmhouse (over 4000 square feet) built in the 1895 that sleeps 14. We rented the newer, smaller cottage that sleeps 6, and we were happy to see that it had recently been outfitted with a mini-split so we had air conditioning during the 90-degree days. As a bonus for us, the farmhouse reservation was canceled so we had the whole property to ourselves!

Greg and Scottie are the owners but Greg was busy with projects and Scottie was away, so we spent the whole time with farm manager Denny, and we also got to chat a bit with his wife Kate. Denny and Kate were both wonderful, and I marveled at Denny’s patience for answering our endless questions.

Denny met us at the house when we pulled up. It was around 5pm so we headed out on a tour and started our first round of “chores”. When they say chores, what they really mean is letting us participate in the best parts of the farm. Every morning at 9 and every evening at 5, we’d meet up with Denny and either let all the animals out of the barn or collect them back in the barn. We’d get hay down from the loft, feed them all, etc. We helped muck the stalls too. Denny also showed us how he moves irrigation around the farm, how to prime the pump from the natural spring after the power goes out for a while, and how to run the pump from the creek on the property.

When we weren’t with Denny, we had free reign of the property to hang out with the chickens, turkey, peacock, sheep, goats, cats, donkey, and horse. Tyla loved roaming the property to find Chip (donkey) and Tater (horse). It’s good that all the animals were so friendly because Tyla spent a lot of time petting them all. We all enjoyed hanging out by the creek and walking on the trails too. Elijah loved having free roam of the property and once he knew the rules, we cut him loose to explore on his own.

It was a tough week on the farm, and we tried to stay out of the way while Denny dealt with some animal issues, but we also appreciated him sharing his thought process on how to handle the various situations. I heard someone say that “interested people are interesting” and I loved hearing Denny talk about the farm. He clearly loves it, knows a lot, and enjoys the continued learning process.

Most of the time when we go on vacation, Tyla and Elijah both ask, “Can we come back here sometime?” That happened here too, but there were more tears shed than normal when we left this place, and Tyla is already trying to book a return visit.

Thank you to Denny, Kate, and the whole crew at Leaping Lamb farm for a vacation that we won’t forget!

First Tesla Road Trip

Welcome to anotherĀ Tesla Tuesday!

We recently took our first overnight road trip with our Model Y. We’ve gotten very used to daily driving/charging routines and never worry about running out of battery, but what would happen on a longer trip where we had at least one mandatory charging stop and a few nights away from home?

Our destination was about three hundred miles away, and while the Model Y has an estimated 330 miles of range, just like gas cars, you’re unlikely to hit that in real life. Plus, that would mean charging to 100% (not great for the battery) and discharging to almost 0% (not great for the battery and then how would we get back home?) So there would be at least one stop for charging along the way.

Another factor to consider was that our destination was far off the beaten path. The closest slow Level 2 charger (fairly slow, similar to what we have at home) was about 30 minutes away and the closest supercharger was more like 45 minutes away. Couple that with some mountain driving and I estimated that we needed to leave the last supercharger with about 50% battery to make sure we could get there and back.

The online Tesla road trip planner isn’t that useful if you’re not going to have destination charging because it doesn’t let you specify how much charge you want to have left when you arrive or get insight into all your options for planning the route. I prefer to use abetterrouteplanner.com. On that site, I could tell it my real-world watts per hour average (265), how much charge I’d leave home with (90%) and how much I wanted to arrive with (40%). Then there are even more options for whether you’d like fewer (but longer) stops or more (but faster) stops. The Tesla batteries charge the fastest from about 15-40% so if you’re really optimizing for ~5 minute charging stops, it’s best to stay in that range, but obviously that means more stops along the way, so you have to balance it all out.

My family needs to stop for a lot of bathroom breaks. I plan one every 60-90 minutes and sometimes we’ll get lucky and stretch it out to 2 hours. On this trip, I planned one required charging stop that was right next to a Panera around lunch time. Then I had a couple optional stops before and after that where we could get some electrons while using the bathroom.

On the way down, we ended up doing that lunch stop and then one more stop at the last supercharger before heading off into the mountains. The charging worked out fine, my estimates were good, and we arrived with more battery than planned because our bathroom/food stops were slower than the chargers. In fact, when we stopped for lunch, I had to go out and move the car because it was done charging before our food was done being made!

There ended up being a 110v plug that was right next to where we parked, and while that’s a slow way to charge, we were there for a few days so it didn’t matter. I plugged the car in on the day before we left, and we rolled out with 85% charge. On the way back, we made just a single stop for charging and food. Since I charged up pretty far and it gets slower as you go, that one took longer (29 minutes to go from 28% to 84%) But by the time we got our food and used the bathroom, we only waited about an extra 10 minutes and it saved us from making any more stops. We needed a bit of extra juice on that charge because after we got home, we had to head straight to school for a meeting and a trip to/from school is about 14% of the battery.

When planning the road trip, I had been thinking about how much money we would save versus driving the truck. I get about 20.5mpg on a road trip in the truck and with gas averaging around $4.80 that would have been $140 in gas. I estimated that the same trip in the Tesla would be about $15 in electricity. That was a mistake because I forgot that superchargers are more expensive than charging at home. So overall, it was more like $40 in electricity. That’s still a big savings and the savings are even greater if you factor in maintenance costs.

The truck has so much room that it’s super easy to pack and easy to move around to get comfortable. We were nervous about having enough room in the car since we’re used to packing in the truck, but when we hit the road, we had tons of extra space. The frunk and the under-trunk storage suck up so much stuff! Even with a big cooler in the trunk, we were at about two-thirds capacity.

Having autopilot on the long drive was nice. I could go for long stretches of road without constantly monitoring my speed or making minor corrections to stay in my lane. Traffic was heavy the whole way so it was annoying to come off the autopilot (lane-keeping) feature every time I wanted to change lanes, but in the back of my mind, I knew I could have paid money to avoid that so it wasn’t too bad.

I spent a lot more time planning our route than I would have with the truck, but now that we’ve got the first big road trip under our belts, I think future ones will be easier. It’s nice to know that the car is also watching our battery and if we ever did something dumb, it would scream at us and direct us to a charger. I think long road trips in the truck will be more annoying now without the benefit of Autopilot. It’s amazing how much less fatigued I felt after a long drive just from not having to spend the energy to stay in my lane. It doesn’t seem like much but it really adds up over the hours. And since the battery lasts a lot longer than our bladders, the charging stops weren’t much of a factor other than having to plan to stop at certain places.

I call this experiment a win and look forward to more road trips with our Model Y!

Living Wills

Earlier this year I was asked by a medical office if I had a living will. I knew my answer was yes, but it got me thinking more about it. I remember talking to our lawyer and just using the default form that he usually used. As a Christian I never felt great about it, but I hoped that Tyla and our Pastor would base their decisions on the Bible.

Fast forward a few months and I heard about free living wills from Christian Life Resources. They’re actually Durable Power of Attorney for Health Care documents (more comprehensive than living wills), but they explain the difference and why you would prefer one over the other. They have unique versions of the documents for each state along with a guide that explains what every choice means and how we view it in light of the Bible. It made it super easy for us to get some documents in place that more accurately reflected our wishes.

To get them officially signed, there are a few options in our state, but we chose to get them notarized. Our bank does that for free, so before too long, we were done!

We put the papers in with our will and then emailed them to our parents so that others have them readily accessible.

This is one of those things that’s easy to put off, but Christian Life Resources made it so easy to get it done. If you’re interested, you can get all the information for free at directives https://christianliferesources.com/resources/christian-medical-directives.
