WATCH: Biden to replace federal government's entire fleet of vehicles with 'net-zero emissions' cars—which don't actually exist

President Joe Biden discussed replacing the government's entire fleet of cars with vehicles that have "net zero emissions." The problem is, they don’t exist.

During a Monday press conference, Biden said that he plans to replace the federal government’s "enormous fleet of vehicles" with "clean electric vehicles made right here in America, by American workers, creating millions of jobs."

Biden then corrected himself to say, "a million auto worker jobs" and continued, "and clean energy, and vehicles that are net zero emissions." This technology does not currently exist.

He then called it the "largest mobilization of public investment and procurement, infrastructure and R&D (research and development) since World War Two."

Manufacturing the vehicles will come with its own challenges including unions, wages and parts, but the bigger challenge is creating a technology that does not yet exist.

While companies like Tesla strive for net zero emissions, they have not achieved it yet. Using Tesla as an example, according to a report produced by Tesla and published in WCCFTech, "A Tesla Model 3 used for ridesharing and recharged using solar energy emits zero grams of Carbon Dioxide during its use, and its total emissions during lifetime including manufacturing are roughly six percent of the total emissions of a mid-size premium ICE (internal combustion) vehicle."

However, electric cars are charged through electrical grids which have their own emissions they would need to eliminate to reach "net zero emissions." Many are still powered by coal and Democrats typically refuse to build more nuclear power plants to boost energy production. Some politicians are even studying removing hydro-electric dams, one of the cleanest alternatives, because of the effects on fish in the bodies of water that power them. The EV batteries can use up to ten times the power an average household uses in a day if they need a full charge.

The process of manufacturing the cars has its own emissions to reduce before "net-zero" is a reality. According to Tesla's 2020 report, "Emissions when manufacturing a Tesla Model 3 (except the battery pack) reduced by roughly 21% during 2019 over 2018."

In fact, according to Tesla's report, "Manufacturing-phase emissions for a Tesla Model 3 under personal use and charged via solar energy are 128 percent higher than the manufacturing phase emissions of a mid-size premium ICE vehicle."

One of the main contributing factors is the battery. According to research done by Forbes, "the manufacturing of a full-sized Tesla Model S rear-wheel drive car with an 85 KWH battery was equivalent to a full-sized internal combustion car except for the battery, which added 15 percent or one metric ton of CO2 emissions to the total manufacturing."

That is one of the reasons Tesla and other electric car manufacturers have placed so much emphasis on their battery recycling program and extending the life of the vehicle. To mine the lithium for the battery is process that currently has a very large carbon footprint and has had adverse affects on other aspects of the environment, including sea-life.

The article went on to say that, "Before anyone gets really excited about smaller cars, basically the report says you have to be driving a tiny hybrid in a serious coal generation area before the Tesla is equivalent full lifecycle to any internal combustion vehicle."

Though Tesla is refining their methods and aspiring to create the "million mile battery," it has not been achieved yet. Tesla and other auto manufacturers R&D departments are spending billons of dollars to achieve the goal of "net zero emissions," but we aren't there, regardless of Biden's plan.
