“In our case, vehicles are driving on sunshine — no other source,” says Desmond Wheatley, chief executive of Envision Solar during our visit. “Our network is rapidly deployed because the businesses or government entities using it do not need to get any permits or incur any construction costs. It is scalable and can serve any fleet while the solar-powered vehicles create no emissions.” The modern version of the enterprise got started in 2011 when Wheatley joined it and became its chief executive. In April 2019, the company got listed on the NASDAQ as EVSI — selling initially at $6 share and now at around $9.50, driven up by institutional investing and adding contracts. The business case?
Tech Corporations Are Fighting To Be Leaders In Green Energy. From Apple and Facebook to Google and Microsoft, big technology firms are in a race to help build a green internet. This means a commitment to powering the company’s initiatives and business operations through green energy. In the latest 2017 report, global brands like Google, Apple and Facebook were graded A in the clean energy index.
Today there are 1.2 billion cars on the road globally — a number that will grow to 2 billion in 20 years. Only a fraction of those vehicles are EVs, although Wheatley expects that to escalate rapidly and especially as the cost of car batteries continues to drop; they are the most expensive part of the vehicle but already the price of such devices has fallen from $2,500 a kilowatt-hour to $400 — and on its way to $100. The internal combustion engine, by comparison, has largely reached maturity.So, if this fundamental paradigm shift reaches fruition then millions of EVs will need an expansive fueling infrastructure. By Wheatley’s estimate, “hundreds of millions” of EV-charging stations will be required. In California, the correlation is now about eight vehicles per each charging station. But a one-to-one ratio will ultimately be needed.
“When we look at the complications of grid-tied EV charging, there is too much time and money involved,” says Wheatley. “Beyond that, the grid has nowhere near enough capacity to meet its normal load and then supply millions of new electric cars. It would need 20% more capacity.”Landing at ScaleThink of Andrew Higgins, who invented the Higgins Boat that was used during the invasion of Normandy during World War 11: The idea was first shunned but was later adopted when the sea craft was shown to operate in shallow waters and capable of amphibious landings. Thousands of boats were used to deploy tens of thousands of troops. To that end, the Higgins boat needed no ports or bridges.
And Europe and North Africa could run on 100% renewable energy by 2050.
Wheatley uses the same analogy concerning the installation of his solar-powered EV chargers: They can land at scale and they require no infrastructure. At the same time, each charging station is a parking spot. That is, a tractor drops off the completed charging port: the solar arrays are on top while the electronic equipment is just below. The car pulls onto the platform, plugging into the battery charger that is configured into the network. What’s interesting is that its “Solar Tree” charging network is offset by a sponsor — similar to the naming rights of a stadium. It’s about building brand recognition. In this example, consumers pay little-to-nothing to fill up.
Consider the case of New York City, which is Envision’s biggest client: The city has 36,000 vehicles in its fleet of which, 2,000 are electrified; the goal is to get to 100%, including garbage trucks and buses. The return on investment begins the day the network is delivered, says Wheatley. That’s because of the avoided construction costs. In New York City, it cost $2,000 per foot to dig a trench with the necessary cables before filling in the holes with asphalt. If it is a 100 foot trench, the cost is $200,000. Wheatley says the EV-ARC is $65,000, which also saves between $40,000 and $80,000 in electricity expenses over 20 years.
“Once they have decided to electrify, they must have the charging,” says Wheatley. “It is much cheaper than buying gasoline and doing maintenance.”
A Ray of Light
Anything that might blindside the company? Given the decline in battery prices, coupled with the low maintenance and fuel costs, Wheatley believes in the market fundamentals. Over a vehicle’s lifespan, he says the cost of ownership will be less than that of a car running on the internal combustion engine.
At the same time, the average American drives about 32 miles a day while most EVs have a range of 100 miles, with some able to go 250 miles per charge. Fast-charging stations can fill up the vehicle in less time than it takes to eat lunch, Wheatley says, enabling a car to go 200-plus miles per one-hour charge. And while today’s technology is “conductive” and requires owners to “plug-in,” tomorrow’s technology will be “inductive” and allow for wireless charging.
“Even today, EVs are competitive if you understand total cost,” he says. “Moreover, even the dirtiest coal-powered electricity is cleaner than gas or diesel. And more and more companies are producing renewable-energized EV charging stations or using renewable energy off the grid.”
What is needed is an expanded infrastructure. It is a matter of free-market economics and consumer demand: car companies do not like making different cars for different markets, preferring instead to use the same factories and robots to mass-produce the same vehicle models — whether they be in California or Kentucky. To be economically viable, car manufacturers must produce for the global market. The European countries, for example, have vowed to go all-electric in the next 20 years. That will force even the most resistant consumers to ultimately get on board — made easier after they crunch the numbers and see the performance levels. Politicians wedded to the past can slow down progress. But they are powerless to stop free market forces.
Renewable Energy Creates 5 Times More Jobs Than Fossil Fuels. An analysis done by the Department of energy in USA has discovered that throughout the nation, clean energy jobs outnumber fossil fuel jobs by more than 2.5 to 1. In fact, when comparing clean energy jobs to those of coal and gas, the renewable energy sector has created 5 jobs to every 1 job in the fossil fuels industries.
“At some point, the mighty U.S. consumers get involved,” says Wheatley. “I do not care who is in office, no one will get in the way of what consumers want.”
Automotive companies are bringing increasing numbers of EVs on line, causing the charging infrastructure to expand. But that network has miles to go, requiring fast and scalable solutions that are also clean and affordable — a dynamic that means off-grid, solar-powered stations are just around the corner.
