Can you tell the exact time when the snow finally melted in Iowa and it began to feel like spring? I will give you one guess looking at the image below:
It was like someone opened a door and spring rushed in looking for treats like a good boy. I said it last year and I will say it again this year…I need to get a roof rake so that I can brush the snow off when it refuses to slide off my solar panels. The way these things go it will probably be a very light snow year next season and the roof rake will sit in the garage unused for months.
It is my hope that April sees a production number on par with the prior year as the previous few months have really been mediocre in terms of solar production. There is something ironic about getting an electric vehicle at the same time that my solar production fell off a cliff. Oh well.
Speaking of the Nissan Leaf it also had a month when it became obvious that the weather had turned. I drove 603.4 miles at an average efficiency of 5.0 miles per kWh. This compares with average efficiencies of 3.6 and 3.9 miles per kWh in January and February respectively.
Two factors played into this efficiency increase: warmer weather that resulted in less use of the resistive heater and better knowledge of how to wring out mileage from the vehicle. It is kind of amazing how you can optimize your driving along a route without resorting to any crazy hypermiling or vehicle modification. This is the kind of improvement that makes me wonder how much efficiency we can wring out of the transportation system without having to resort to draconian measures.
Over the course of the past two and a half months I have driven a total of 1583.6 miles in my Nissan Leaf. That has saved 1731.9 pound of CO2 versus my prior vehicle and cost a total of $49.34. The emissions and cost numbers are based on me using grid electricity for the entirety.
As an aside, I utilized a public charger for the first time this month. In practical terms it was super easy. I pulled up to one of the two spots at my place of work, tapped my Chargepoint RFID keycard, and got to charging. There has been a lot of talk about infrastructure for charging and how it impacts the widespread adoption of EVs. In my experience, the publicly available charging infrastructure is not the major hurdle to adoption for a lot of people. Unlike urban areas, the suburban area that I live in is rife with attached garages where people can charge their vehicle at home overnight. Within line of sight of my garage are two houses with Tesla Model 3s and in conversations with the owners I have found that they also rarely, if ever, utilize public chargers, including Tesla’s vaunted Supercharger. It is just not necessary for the majority of driving that takes place in an average day. Heck, I only used the charger at work to ensure that my Chargepoint card worked so that I could take my Leaf down to Iowa City in the summer.
