Sunshine is the new gasoline.

It's about the economy and the emissions. 


My Fuel Station, 14 cents for regular, 9 cents for TOU.

1.   The cost to power our two BMW i3's by solar is the equivalent of $0.14 per gallon of gas.

2.   The GHG's caused by our collective transportation choices are the largest source of emissions in California.

3.   In California, there are over 500,000 solar PV installations and 50% of all EV's and PHEV's sold.

4.   The emissions reduction of driving an electric car powered by solar energy (solar used as a transportation fuel) is 400% greater than the emissions reduction of the same amount of Solar used to power our buildings (solar used as utility fuel.)


Sunshine is the new gas.  

Your home is the new gas station.  

California is the Golden State,  basked in sunshine and leading the world in solar PV and electric vehicle adoption, development and manufacture.

The  writing and case study herein is based on our "real world" experience as solar and EV pioneers over the past decade.  It just is what it is, put into practice in the real world, in our real lives.... and it's getting cheaper and better with more EV&PV combos every year.

It's a California located story, and this is not typical across the 50 states, but there is an old saying:  "So goes California, so goes the Nation.

Today, California has over 500,000 homes with solar PV on the roof tops (data here)  and over 50% of the National EV & PHEV sales, (data here)  both these numbers are rising exponentially.

Our state's success is a sweet California Cocktail mixed with portions of innovation, entrepreneurialism, regulation, legislation, adaptive utilities, risk, incredible cities and self reliance.   It's a cocktail best served warmed by sunshine.

This "California Cocktail" is slowly becoming popular in other states across the nation as renewable energy and EV adoption rates increase.

If you don't want to drink the Kool-Aid California Cocktail, feel free to abstain and mock, but know this:

The rigid status quo will yield to a better and cleaner future.

Economics:

Julie and I completed our one year Driving to Net Zero energy challenge in May of 2015. (Article here) From the challenge we documented to the last kWh, the total miles and kWh's used driving our two BMW i3's for the year.

Here is the cost (in the image below and here) of a solar PV system in San Diego California.

The cost after Federal tax credit is $2100 per kW system size. 

When you add the Driving to Net Zero Energy Challenge data to the cost of solar PV this chart is the result.


The purchase of a Solar PV system when used as transportation fuel, has a payoff of two years and an ROI of 50%.   Simply take two years of gasoline cost and you arrive at the general cost of the solar PV system.  It's slightly higher than two years, however when Time Of Use Rates are factored in, it becomes slightly less than two years.  Of course your results will vary depending on location and the type of EV you drive.  The BMW i3 is by far the most efficient EV on the market (data here)    


The cost of Solar fuel is 4% of the cost of gasoline averaged over a 25 year span. This translates to $0.14 per gallon flat cost and $0.09 per gallon when SDG&E favorable Time Of Use rates are factored in.

The solar PV system is warranted for 25 years including the micro inverters, it will last much longer than that. 

Emissions. 

One gallon of gasoline when burned in a car emits 19.64 lbs. of GHG's. (data here)

7 kwh of solar electricity (this will drive an electric car the same distance as a gallon of gas) emits zero GHG's.

The same 7 kwh of electricity from the current SDG&E grid mix when used in our buildings contains .7 lbs of GHG's per kWh for a total of 4.9 lbs of GHG's.
(data here) The SDG&E grid mix is 37% renewable energy with the remainder Natural gas, thus the reason for the lower .7 lbs number.

As cities in California and elsewhere make Climate Action Plans to lower their emissions, the 100% renewable energy platform as relates to our buildings energy use is a very popular tool with the public as the public understands solar as a utility cost savings.  What is lessor understood is the use of solar as a transportation fuel.

If we are to use emission reductions as our number one goal, and we use science and common sense, not populism, to guide us, we would come to a strategy that uses 100% of renewable energy generation to offset transportation emissions resulting in a reduction of total GHG’s that is 400% greater than a strategy that uses 100% renewable energy generation to offset utility supplied electricity for our buildings.  Of course doing both is the best answer, but the fastest and best path is clearly transportation.

Focusing on a strategy that targets the 59% source at a 400% greater yield in GHG savings is preferable to focusing on a strategy that targets the 15% source at a yield that is 400% less. 

Solar is getting less expensive, EV's are getting better and less expensive,  Range is going up across all models with 200 miles of range as a new standard. our homes are becoming our gas stations,  our cost of fuel is getting lower.

It's awesome :)

The Arcimoto SRK, A Perfect Fit For Relocalized Cities.


Lightweight, electric vehicles for the city…Part one of two

Relocalization:  The opposite of urban sprawl. 
Arcimoto:   The evolution of transportation.

Arcimoto SRK

Heretofore, no machine has been better as a conduit connecting us to our relationships than the personal automobile. It’s why we willingly turn over 50% of our land surface in large urban cities to asphalt and concrete in the service of cars, it’s why we spend a large chunk of our personal and civic income on cars and their required infrastructure as the basis of our transportation network.    

Awesome times on the open road in a 68 Chevy Camaro

Cities have been around for 10,000 years, beginning with Damascus, Athens, Jericho and others.  What’s hard to comprehend is that for roughly the first 9,800 of those 10,000 years, transportation remained absolutely unchanged.  

Walking, riding an animal or getting pulled by an animal(s) were the only forms of land transportation until the early 1800’s.


200 short years ago we began traveling by steam power in trains and ships.  We began riding bicycles instead of animals.  100 years ago we began driving personal automobiles and motorcycles. 60 years ago we connected the USA with the Interstate Transportation System, with cities now untethered from a port or rail head. 10 years ago we began car sharing with Zipcar, 5 years ago we began to Uber and bike share.  Today we are changing our motive power to electricity, in the near future electric driver-less cars will enter the scene.

Transportation is evolving rapidly.  Each evolution offering benefits and challenges to our cities, each evolution with the power to alter the rich tapestry and land use patterns in our cities for worse or for better. 

“Any overabundance of a strength, can become a weakness” (think of a personal strength of yours that when overdone becomes a weakness.) This truism rings loudest for the automobile and the Interstate Transportation System.  

Where once the open road offered freedom, it now offers congestion, mindless repetition of places, soul thieving examples of generic sprawl in and near our cities. 

Where once we would spend time involved with little league,  PTA’s, charities, houses of worship, or a passion of our choice, we now willingly make the decision to spend this time alone, isolated in a car for two, three or four hours a day. 


Where once we had room for people in our cities, we now give more room to cars and less to people.  

Our love for cars, mine included, is the epitome of a strength that when overdone turns into a weakness.   Urban sprawl is the generic all-inclusive term for these shortcomings.  What is emerging in our cities now is a desire to address these weaknesses by dialing down the singular focus on the car.  


We more often are making the choice to live closer to where we work, choosing a dynamic neighborhood with a unique identity rich in consumer choices and mobility choices within a short distance.  Advances in transportation options are now connecting us for the last few miles to home and work.  City roads once the sole domain of cars, are now legally shared with bicycles and other modes of transit.

Lastly, there is a new vehicle class emerging that is tailor made and fine tuned for life in the city. These vehicles are lighter, more efficient, requires less space while still providing for the needs of drivers.

There is a profound change now underway in our cities that I refer to as Relocalization, the opposite of Urban Sprawl. Vehicles such as the 1000lb 2 seat Arcimoto SRK  are the vanguard of this new era in mobility. 

Relocalization is:
  • Reconnecting with people.
  • Regaining time.
  • Reengaging with your community.
  • Restoring a sense of place and identity.
  • Restructuring energy & transportation for cleaner, healthier cities.

Out of a total population of 320 million Americans including children and the elderly, there are approximately 250 million Americans of driving age. Do we really need 253 million registered cars and trucks?

It's not that we need to get rid of the car,  but a family of four does not typically need four cars.  Just a reduction of 25% to three cars and a transit pass, or 50% to two cars, an Arcimoto and access to car share would greatly repair and rebalance our cities.

In part two of this post, I’ll explain my upcoming effort to go  “Car-less in Carlsbad”  with the Electric Arcimoto SRK. Our family will soon migrate from being a two car family (plus one highly collectible machine that I rarely drive) to being a one car and one Arcimoto family. 


We can do better.  It’s an exciting future. After 36 years driving cars mostly alone,  I’m ready to try a future where the large majority (90%+) of my transportation needs will be without a car.  

Cheers from the edge of imagination, creativity and transportation.

A Drivers Review, The “Absolutely Electric” Arcimoto SRK

In 2009, I was fortunate enough to become a field trial driver of pre-production electric prototypes; first the BMW Mini-E followed the BMW ActiveE. I drove both for five years in an effort to understand where we were going as we transitioned to the future of electric transportation.

Heady...but uncertain days in 2009 with the BMW Mini-E

2016…. Enter the Arcimoto SRK.

Heading to my County of San Diego Planning Commission Meeting.

Do you ride or drive the Arcimoto? Tough question to answer, I’ll go with ride.  Riding the SRK these past few days, brought me mentally back to early 2009 comparatively speaking, when I was first handed the keys to the prototype BMW Mini-E.   Heady days…

Imagine the ability and resources of BMW, a 100 year old company that produces approximately 2 million vehicles a year, in putting together a prototype electric car program and showing that pre-production car to the world.   Now imagine the resources of a small but mighty Oregon based startup called Arcimoto as they begin traveling the same path, demonstrating their pre-production prototype to the world.

Two in one parking space, both connected to the dual head L2 charger
As a driver of both the BMW Mini-E and now for a few days and several long trips, the Arcimoto,  I was amazed to find that the prototype SRK is far more refined and closer to production ready than was the Mini-E.   High praise for the Oregon based Arcimoto and their ability to execute a well thought out plan. 

The vehicle architecture is sound, stable and robust, nicely put together with attention to a high design ethos.  A few little tweaks to the steering assist and steering feedback levels, the emergency brake location, and the hydraulic foot brake location are the only obvious improvements that are needed. All are known realities of a one off prototype and easily addressable in the next phase of pilot vehicles.   It’s darn near ready to be displayed in a new vehicle showroom and sold as it is.

BMW C1 enclosure and cross seat belts.


The SRK pulls some vehicle architecture inspiration from the 2000-2002 BMW C1 with the roll cage, cross seat belts, and upright car like seating position.   This along with the three wheel stable platform, allows the rider to ride without a helmet in certain states such as Oregon and California.   Where the SRK improves surpassing the BMW C1,  is in its quiet electric drive train, 3 wheel stable platform, two seat configuration and freeway speeds.   On the road the SRK feels more car like in ride quality.  The suspension is top notch. I'm just guessing that the engineer in charge of the SRK's suspension dynamics has some track time in the seat, as the double wishbone race car like suspension is that good.

The three wheel configuration also positions the SRK as a preferred platform ready to enter the world of shared and autonomous driving.   It's easy to envision a future where a train commuter gets on a SRK and takes it the last 3 miles to the workplace.  After arriving the SRK would then autonomously reposition itself back at the transit station or drive to the next customer who has hailed a ride, perhaps at a hotel or shopping center.

You can also see a future where an operator like Zipcar or DriveNow would have thousands of SRK's in each large city.  It's low cost, zero emissions, off the chart fun factor and the ability to have fleets of SRK's in 1/3rd the space as the same number of cars,  gives transportation planners and car share companies some new tools in the toolbox.

That's an exciting future.

One of many test drives in the SRK, smiles all around.

These past few days, the two SRK’s were introduced to several hundred San Diegans via test drives & static displays, as well as trips up and down scenic coastal North San Diego County. Everywhere the SRK’s went they were greeted with high fives, thumbs up, waves, and lots of cameras.    All age groups from seniors to high school seniors were interested in the stories and solutions represented in the DNA of the SRK’s.



When a ride like the SRK draws more attention and “Out Gawk’s” the ultra beautiful BMW i8 parked in the next space, it has my attention and should have the automotive world's attention as well.   When it’s on the road in front, astride or behind you, you just can’t help but smile at how "uber cool" and how unique is the SRK.

Carlsbad Cars and Coffee,  The hit was the Arcimoto SRK's
Tough to please "gasoline guys"  wanted to learn everything.

When pulling away from a light, you can’t help but be surprised how quickly it sprints to 70 mph. It may be cool, that’s true, but it’s also seriously quick, stable and a friggen blast to drive, err, I mean ride.   Coming to a stop, the regen is perfectly integrated in a hand lever on the throttle side of the handlebars.  You feed in the regen by how hard you squeeze the hand lever.

I would estimate the max amount of regen as twice as strong as the BMW i3 which has the most regen of any car.  I love it and it's super easy to use.  It's the best regen system I've tried and I've driven almost every electric vehicle there is.  Think bicycle hand brake simple, the harder you squeeze, the more regen.

You don't have to use all that regen but you can certainly ride the SRK without using the friction brake.  The friction brake is down on the right foot pedal in a traditional position. 

Anticipating riding the SRK before its arrival, I was contemplating its “limited” use case in my mind.
  
After “riding” the SRK  up and down the California coast for a few days in early February,  It’s clear to me that this vehicle architecture is intersecting with history at exactly the right time and that its transportation use case is broad.  Far broader than a motorcycle, far broader than a convertible and far better than a car in metrics such as parking, efficiency, pollution and cost of ownership for urban and suburban dwellers. 

Coffee Coffee, Surfy Surfy, SRK, SRK

Will it haul your four kids around? No.    Will it get you to work, get you to the restaurants and stores, get you to transit, and get you 100 miles down the road at freeway speeds, absolutely.  What a blast of fun you’ll have getting there. 

As our nation continues its migration to cities and our citizens more often making the choice to live closer to where they work and closer to families (the opposite of urban sprawl,)  vehicles such as the Arcimoto SRK will play an ever increasing role connecting us to our transit options, to our work, and to each other.

It’s not a motorcycle, it’s not a car.  It’s an Arcimoto.  

February cruise along the sand.....Paradise.

I look forward to the pilot series of vehicles from Arcimoto and then the retail offerings across the nation.  After spending a few days exploring this unique vehicle and spending time with its CEO, suffice it to say, I think they are on a great trajectory. I think they have the "secret sauce" and I wish them wind in their sails and wisdom in their decisions for the next few years of their journey.

Powered by sunshine!

Bravo Arcimoto.   

I seem to have room for one more vehicle in my garage.

Electric Bike, Electric BMW i3 & Electric Arcimoto SRK


We're liking the Arcimoto SRK, come join us for a test drive :) 

Arcimoto SRK, Fun open, practical electric mobility

A bit of history, Julie and I are proud to be among the early EV Pioneers ushering in electric mobility. We began in 2007 with Solar PV and in 2009 as Field Trial drivers with BMW in the pre-production prototypes, the BMW MINI-E & the BMW ActiveE, both very important vehicles in the development of the BMW i3 and BMW i8, all driving on electricity produced by harvested sunshine. We are continuing in that electrifying pioneer spirit with our exploration of various classes of electric mobility. 

We're excited to to be hosting along with EVOasis, the San Diego launch event for Arcimoto this Thursday February 4th from 4pm to 7pm. 

If you're in the San Diego County- Orange County area, we invite you to join us after work  on Thursday for a test ride of the Arcimoto SRK & a little woodfired pizza.  Just RSVP at this link if you can make it.

https://www.facebook.com/events/743212472490317/

It looks to be a fun and informative night. The CEO of Arcimoto, a Eugene Oregon based company, as well as local San Diego companies in the electric vehicle space will be present. 

Why the Arcimoto SRK? 



There's a huge chasm both in functionality and cost between the 50lbs electric bike and the 2600lbs BMW i3 which is one of the lightest four passenger cars on the market. 

Different forms of electric mobility. Pick the one that's right for you.

We're very interested in this vehicle class slotted between a 300lbs motorcycle and a 3000lbs car.  At a weight of 1000lbs, the SRK is incredible efficient returning approximately 7 miles per kWh used, it's extremely fun to drive, and does not require a helmet or motorcycle license in California.

Several years ago we had a Gem E4 and although severely limited by the top speed, (25mph) the range, (20 miles) and the need to replace the lead acid batteries every three years, we loved the car.  Why?  Because there was a resort like quality when you were tooling around in the Gem E4.   Open air, panoramic windshield, no noise and simple fun. It's the way driving along the California coast is the most enjoyable, open air and quiet, just soaking in all the sights. 

We're looking to recapture that open air feeling of the Gem E4
This is going to be hard for some to understand, as we love our BMW i3 and BMW i8 a great deal,  but the Gem E4, even with all it's shortcomings, had a certain magic and feeling about it, almost like you were on a vacation island in paradise, when you were driving it.   We loved taking the Gem E4 to the beach, the lagoon, out for dinner, to a play, and to the local grocery store.  Neither the i3, or the i8, nor any enclosed vehicle can give you that feeling.  Crazy huh?

Enter the SRK. 

The Arcimoto SRK provides that same sense of openness, quiet driving pleasure while eliminating the downsides of the Gem E4 as far as range and speed.  The SRK is also in my view a great platform to develop for future car share programs and for the future of autonomous driving.

First, it has three wheels and is a very stable platform,  this means that in the future world of autonomous driving,  the SRK will be able to come to you autonomously,  or return to a nearby transit hub by itself once you have finished driving the SRK.  This is simply not going to be possible with most two wheeled bikes and motorcycles.    

Toyota iRoad, the MIT PEV and others are also exploring similar vehicle architecture casting their vision forward in anticipation of shared vehicles and more efficient mobility. 

MIT PEV
Toyota iRoad
Second, you can park three of the Arcimoto SRK's in the space of one typical car. In our crowded cities parking is at a premium and vehicles like the SRK if widely adopted would mean that we begin to solve that problem with less real estate devoted to transportation parking.  

Less space for parking lots, more space for people. 

Third,  The freedom and fun of driving. There's a reason Americans are in love with motorcycles and convertibles. With the Arcimoto SRK and its open airy design language (more open air motorcycle, less closed in car,)  the Arcimoto has that freedom and fun in spades.  It's in this important category that the Arcimoto is superior in my view, to those who are trying to enclose and mimic a more car like form with a three wheel option. 

What Arcimoto got spot on right, is keeping the openness and resort fun feel to the SRK while providing  for a semi enclosed cabin that does not require a helmet or motorcycle license in Oregon or California.  It offers more stability and safety than a motorcycle and if the weather's not cooperating,  take a few minutes and attach the optional doors.

Cruising a scenic corridor, in our case the California coastline, the mountains and the desert of the Anza Borrego is best done in an electric, zero emissions, open air vehicle for two.

Depending on your needs, your lifestyle, your vision of the future & where you want to go,  you might be surprised at how much value and functionality the Arcimoto SRK can deliver.

Can't wait to drive the Arcimoto SRK this Thursday February 4th,  Join us if you're in the neighborhood and want to test drive the near future of electric mobility.

Cheers!

BMW, Tesla... Doors done differently.

A needed disclaimer, I'm an i8 driver and an i3 driver. So bias detection is allowed by the reader. 

Car doors are typically generic & mundane, but doors can be so very "aufregend!"

With the BMW i3, BMW i8 and the Tesla Model X, doors can be downright friggin amazing! Gizmos, gadgets, carbon fiber and lightness.


Tesla Model X

Let me be "Captain Super Obvious" here and point out that an engineering overdose, and an engineering reboot  was required to provide for the Tesla Falcon doors.



Tesla can rightly lay claim to the most incredible structure ever required to get the doors of a car to open. My guess is this is the last time we will see the Falcon door solution on any production car sold due to the cost and complexity of the door.

For Model X owners this rarity could be very valuable and super exclusive....sort of like the third directional headlight of the Tucker 48 "Cyclops" that rotated the headlight in the direction that you turned the car, an innovation that was 60 years ahead of it's time.

Recently at auction a 1948 Tucker 48 sold for $1,567,500

On the other hand, the Falcon doors could be remembered as an unneeded over complicated, over sensored, trouble prone solution to the simple act of opening a door.


Time will tell if the Falcon doors was a "kitschy gadget" partnered with traditional doors for the front seat occupants, to wow us demanding our attention... or... a great piece of engineering, albeit a complicated one including many sensors, situational awareness, springs and struts that provides a solution to a real problem.

BMW i8

Of the three different doors, I like BMW's solution of the Swan door for the BMW i8 the best. Swan or Butterfly doors have heretofore been very hard to do, but with the BMW i8, it's accomplished very simply with a beautiful minimalist approach. Strong fixed attachment points on one plane, Strong and light carbon fiber, and a single strut that's visible, accessible,  easy to inspect and replace if necessary.  Due to this very straight forward simplicity coupled with BMW's increasing use of carbon fiber,  I do expect to see future BMW Coupe and Sports models with Swan doors. 

 

The Swan door provides great functionality for taller drivers like myself by making it much easier to swing the legs in via the much longer door opening. Getting in and out is remarkably easy for such a small sports car once you find your grove. Yes hitting your head can be an issue on the way out, but you only do it once. 

For tall drivers in a traditionally doored small car or sports cars, contorting your head, sliding down the seat and leg gymnastics are required every time you get in or out of the car. Some cars you simply just can't get in or out of. The long Swan doors also provide great access to the 2+2 back seats, small as they are. When opened the doors project just 18" away from the car. This is a similar or less space than a traditionally operated door requires.

With the BMW i8 Swan doors,  It's a stunning beautiful design that will be easy to maintain through the years.  If you look really closely at the engineering of the Swan doors for the BMW i8, It's a master class of simplicity, lightness and design.

Design matters...



Both the BMW i3 coach doors and the Tesla Falcon doors have some clumsiness associated with them. You must close the rear door in the i3 before you close the front door. You "should"  close the front doors on the Tesla X before you close the Falcon doors. Neither of these actions are required on a traditionally doored car.


There's additional oddities in the BMW i3 coach doors such as the driver and front passengers seatbelt being attached to the rear coach door making it weird dropping off the kids from the rear and having to undo your seatbelt. Parking in tight spaces and using the coach doors can also be problematic.

For the Model X, the Falcon doors are slow to open and close and I can imagine the novelty wearing off quickly as the slow operation of the doors becomes an irritant. Have you ever seen how rough an impatient kid can be on a car door?

Both the BMW i3 coach doors and the Tesla Model X Falcon doors offer greater access to the cabin and ease of entry exit than traditional doors, with the Falcon doors being vastly superior in that important area.

Both Tesla and BMW deserve a lot of credit for giving us innovative, interesting and in the case of the BMW i8, drop dead gorgeous doors.

Doors can be so "aufregend" cool.

The BMW i3 and Solar PV, an enriching relationship at a beautiful scale.

It's just 30 ft.  from the panels to the EV plug. 

We've arrived at zero net cost (-$472 actual) for the energy required to live in our home and drive our two electric BMW i3’s powered by Solar PV.

The utility savings from our Solar PV system installed in 2007 and the gasoline savings from our EV driving beginning in 2009 with the BMW Mini-E, led to our energy plant / Solar PV system being fully paid off in April of 2012.  For our family, we have an ongoing savings of around $8000 a year continuing for the next few decades. 

But there’s another side of the story to tell, a story of design scale and the relationship between the car and the source of fuel that's both surprising and fascinating.

Design. 

Good design has a natural scale, for example the scale of an object as compared to a person, such as the height of a ceiling.  Or the proximity of an object to another object or person, such as landscaping, that when done well provides a sense of comfortableness, a feeling of beauty.  It works well and fits together nicely.  

When not done well, a poor design scale can seem awkward, weird, and uninviting.  “What the heck were they trying do here” is a typical response resulting from poor design scale.  

Now let’s take a look at the design scale between the car, a parking space, and the space required to power the car a typical 12,000 miles a year.

An average parking space for a car is 9 ft. by 18 ft. for a total of 162 ft. An average residential garage space per car is even greater at more than 200 sq. ft.


From our real world "Driving to Net Zero" experience, we know that our car the BMW i3, requires 2860 kWh to drive 12,000 miles.  We also know that for each kw in system size our Solar PV system located in coastal California produced 1588 kWh.   For our individual situation, a Solar PV system size of 1.8 kw is required to provide the electricity to drive our BMW i3 12,000 miles a year.

For a better comparison, let’s design an average system size that will work for the majority of electric cars in all areas of the USA.   

The efficiency of electric cars range from 3 miles per kWh to 4.2 miles per kWh. Additionally, solar resources vary across the nation.   Factoring in the lowest solar resources and a larger EV,  a 3 kw Solar PV system size  is needed to power the vast majority of eclectic car choices 12,000 miles a year, anywhere in the USA.
Solar resources across the USA.

How large is a 3 kw Solar PV system?   The SunPower X21 panel produces 345 watts and is 17.57 sq. feet in size at 61.4inches by 41.2 inches.  8.7 panels are needed for a 3 kw system size but let's call it 9 panels for 3.1 kw system to keep the math easy for a total of 158 sq. ft.

To recap:

A typical parking space for most cars anywhere in the USA is 162 sq. ft.

A Solar PV system in California, 12,000 miles in a BMW i3 is 92 sq. ft.

A Solar PV system anywhere USA, 12,000 miles in any EV is 158 sq. ft.

That’s a beautiful proportional design scale.  The size of the space required to park a car is larger than the space it takes to provide power for the car.

You're probably thinking to yourself, this will never work, the $9,000 to install the 3 kw Solar PV system for the car over one parking space is too expensive.

Do you ever think about how expensive that parking space is?  A paved parking space can run from from $4,000 to $40,000  (source link)  each depending on location and we've managed to build 4-5 for each car in our cities.  One space at home, one on the curb, one at work, and one or two out in the city for your use as you shop and run errands.

When you add up the multiple parking spaces per car, it's very clear that providing parking for the car is many times more expensive and land intensive, than providing the energy to power the car during a 25-40 year time frame.  It cracks me up that we still refer to it as free parking.

The parking spaces can be more expensive than the Solar PV.
  
Relationship.

A relationship can be a coupling, cause and effect, harmony between two or more,  the way two or more are connected, a symbiotic reliance on the other.

All cars need an energy relationship to move.

Currently most cars have a required relationship with a gas station. You simply must fuel your car at a gas station.   The gas station stores and dispenses the fuel that arrives by tanker truck from the refinery.  The refinery receives the crude oil from a tanker or oil pipeline.  The oil tanker receives the crude oil from a pipeline or tanker truck that receives it from an oil well or oil source.  

This conveyance chain of hydrocarbons to your car can be thousands of miles long traversing oceans. In this long carbon chain, you are the payer at the end of the chain with all the owners of the pieces of the chain enriched by your payment. 

This long hydrocarbon conveyance chain is also very inefficient, resulting in less than 20% of the original energy contained in the crude oil reaching the wheels of your car where they meet the pavement.   

The electric car also has a required relationship with electricity.  This can be made from many more sources including Solar PV that sits on the roof or carport above one of the parking spaces provided for the car.  The conveyance chain can be as short as 30 feet, from where the sun shines on the Solar panel to your car.  

This electricity harvested from the sunshine supply chain to your car is owned entirely by you.  This conveyance chain supplies the electricity to your car where your car is parked and results in over 85% of the original sourced electricity reaching the wheels of your car where they meet the pavement.

That’s a beautiful relationship between the car, electricity and nature that ultimately enriches you the owner.   We can provide the electricity for our cars in this space with Solar PV at a fixed cost equivalent of $0.50 - $0.75 per gallon of gasoline.

Relationships and design...They matter.

The Highest EPA Rated Mass Produced Vehicle Off All Time! 500% More Efficient Than The Average New Gasoline Vehicle.


You can live and drive powered by sunshine.

Julie and I are fortunate enough to both own and drive BMW i3 Bev's powered by sunshine. Our BMW i3's are the principal reason along with Solar PV and a very efficient home, that we are able to live and drive with zero net utility or gasoline cost.

The BMW i3 is rated by the EPA at 177.7 combined mpg rating (using unadjusted laboratory figures) according the article, an unbelievable 5 times more efficient than the the average new gasoline vehicle which is rated using the same methodology at 31mpg unadjusted.  (Source NPR)

That directly translates into more wealth for those owners and families who own the car, (or any other electric car) and cleaner air for us all.

Consider this from a San Diego perspective.

If we as San Diegans achieve 50% electrification of our transportation fleet, we would reduce by 30% the overall emissions in San Diego County. 59% is the total emissions created by our transportation choices. Just as importantly, we would also be creating wealth and economic savings for our families and communities by reducing the cost of transportation fuel.


Our sources of emissions in the City and County of San Diego


A shift from oil to electricity in our transportation choices enables efficiency gains of up to 700% thus creating economic wealth. As just one example of this, the EPA rates the average new gasoline vehicle at 31mpg unadjusted and the new BMW i3 at 177.7 combined mpg rating (using unadjusted laboratory figures). This is a greater than 500% improvement in miles traveled using the same amount of energy.  The cost savings,wealth generation and improvement in air quality implications if our experience were replicated in an entire city, state or nation is staggering and incalculable.

Most understand the energy savings of a LED bulb versus an incandescent bulb; the same amount of light for 1/5th of the energy used, electric transportation is similar.   In any energy or emissions strategy, efficiency is always the highest priority in the loading order and is wealth generating at an equal percentage to the savings. 

Using our real world experience gained in the "Driving to Net Zero"
Challenge, as compared to the best utility rate and gasoline.


Our highest priority should be reducing and ultimately eliminating the 59% of our emissions in the County of San Diego that are caused by our transportation choices. We can do this by electrifying our transportation choices coupled with equal effort; land use planning that reduces vehicle miles travelled offering greater mobility choices.

As Americans, a long-standing national goal shared by several Presidents of both political parties, has been to reduce and ultimately eliminate our dependency on foreign oil. In 2014, nine millions barrels of oil daily were imported from 75 countries representing 46% of our total oil consumption. We are currently fighting wars involving cost in both money and blood, because oil is still regrettably a strategic concern.

Focusing on getting to 100% renewables in our San Diego electricity grid does zero to contribute in solving this national problem, as our grid contains zero electricity produced with oil.

Focusing on transitioning to electric transportation choices ultimately solves this national problem as the majority of our oil is used and refined to make gasoline.

Looking regionally, are we really willing to dot our backcountry and uproot farmland with hundreds of 50 to 1000+ acre Solar PV power-plants in order to accomplish the goal of getting to 100% renewable energy? (For the record I have supported with concerns, the first several installations as a San Diego County Planning Commissioner.)

Or is the better strategy at least for the next few decades, something less than a 100% renewable energy electricity grid, with a preponderance of distributed renewable energy installations owned by hundreds of thousands of energy entrepreneurs on our existing buildings, parking lots and garages/carports? Solar PV installations that are focused on reducing the four times greater transportation emissions as well as our building emissions.

There are currently 72,000 energy entrepreneurs with solar PV systems in the SDG&E service area. This number is 50x more than existed 10 years ago. In the next 10 years we can easily predict 10x this number.  The energy grid is evolving into a more equitable grid whereby if you provide a benefit, you'll make money, if you are a net user you'll pay money.  Soon there will be millions of energy entrepreneurs on the energy grid.  Sounds like what happened to our communications grid doesn't it?

We have a lot to think about and plan for, unprecedented changes are happening in our transportation and energy sectors. It’s an exciting time of opportunity on all fronts.

Electricity including renewable energy should be thought of  first and foremost as a transportation fuel. 

That’s both our greatest challenge and our greatest hope. Let’s get to work.

Thank you BMW for making a fantastic car to drive, for enriching our pocket books and for helping clean our air.
