As of 2020, the greatest contributor to U.S. greenhouse gas emissions was the transportation sector, at 27 percent. Of that pollution total, 22.4 percent was generated by passenger cars and light-duty, medium-duty and heavy-duty trucks. The remaining 4.59 percent was attributable to aircraft, rail, ships, and other emitters.
To avert global warming, the U.S. needs to transition from the ubiquitous fossil-fuel-burning internal combustion engine to electric and/or other earth-friendly propulsion sources. The vision of zero-emission vehicles is absolute nirvana, a clear pathway to clean skies, improved health and a bright future for our planet. But there is an inconvenient reality: The U.S. generates 60.8 percent of its electricity by burning fossil fuels. Much like our air conditioners, refrigerators, televisions, and computers, EVs can only be as clean as the electricity powering them.
During 2019, California experienced 25,281 electric power outages, a 23 percent increase over 2018. Those outages victimized 28.4 million customers, a 50 percent increase over the 19 million Californians affected in 2018. Recently, electric grid operators’ groups such as the North American Electric Reliability Corp. (NERC) and the Midwest Independent System Operators (MISO) forecasted an increased frequency of blackouts and brownouts during the summer of 2022.
By 2030, 8.7 million EV passenger vehicles and 10.4 million last-mile delivery trucks are expected to occupy U.S. roadways. Assuming annual passenger car usage rates of 13,474, and 12,435 miles for last-mile delivery trucks, at an average of 3.46 miles per kW, that will consume as much electricity as 2.7 million single-family U.S. homes.
Legislation like New York’s Electric Building Act guarantees increased electricity consumption. Also, ever increasing fossil-fuel prices (required to make demand electricity) will increase production costs that will ultimately trickle down to consumers. Boston Consulting Group predicts that increased EV demand will require utilities to invest $1,700 to $5,800 per electric vehicle in grid upgrades through 2030. That $178.7 billion investment will assuredly increase consumer prices.
The Need for Practicality
For EVs to become ubiquitous, numerous hurdles preventing the masses from adopting EVs as their sole source of transportation must be overcome.
Charging at home is both convenient and cost effective for the 67 percent of Americans who live in single family homes. But will multi-car families be willing to interrupt their evenings to plug in a second EV or will they incur the cost of adding another Level-2 charger, or the exorbitant cost of acquiring and installing a Level-3 charger? Moreover, in an emergency, a person’s ability to respond will be limited by the number of EV chargers available along the route, their charging speed, and functionality.
Freedom to Travel Coast-to-Coast
Without millions of fast, reliable, and safe EV chargers throughout the U.S., many consumers will resist EV adoption. For example, in 2021 the California Energy Commission’s Electric Vehicle Charging Infrastructure Assessment warned that the state will need 1.2 million EV chargers by 2030.
The U.S. has over 1.1 million fuel nozzles and a fill-up takes about three minutes. When contrasted against a 150kW DC fast-charger, three minutes provides less than 30 miles of range. Subsequently, to satisfy the motoring public’s needs and to provide peace of mind, the U.S. will require many millions of ultra-fast-output public EV chargers.
True Zero-Emissions Vehicles
In an effort to provide EV drivers with blackout and brownout immunity, offset power plant CO2 emissions, and to provide ultra-fast charging speeds, I created the Wind & Solar Tower (WST). This charger, the only one in the world powered by both wind and sun, is capable of simultaneously charging six EVs at Level-4 DC 380kW 1000-volt speeds that provide about 328 miles of range in just fifteen minutes. With up to a megawatt of battery storage capacity, each tower provides 797,900 miles of pollution-free driving per year and offsets 340.91 tons of atmospheric CO2 emissions.
My wind-and-sun-powered generating plant makes electricity on site for less than half the cost of utility-supplied power. Factoring in certain government programs, kWh costs can be reduced to nearly zero.
Reliability and ease of service are paramount with the WST. My team’s vast engineering and automotive capabilities means self-diagnostic capabilities and a 40-year service life. The WST features the lowest acquisition cost per EV charging outlet and generates – at virtually zero cost – 11,520 20kW charges with 100-percent-renewable energy that supplants electric grid load, which in turn reduce CO2 emissions and averts global warming.
