Will electric bikes save the world?

 "According to the US Bureau of Transportation Statistics, more than half of all trips in the US are under 3 miles.  A University of Oxford study found that swapping a car for a bike just once a day slashed an individual's transportation emissions by a whopping 67%. Another study found choosing an e-bike for 15% of one's miles traveled cut their transportation emissions by 12%.  Fast, fun, and convenient, e-bikes are already helping people make that kind of shift in their daily lives.

While many cities in the US don't have good bicycle infrasctructure, e-bikes should make that somewhat easier as they gain popularity, since travel distance for the average rider will substantially increase.  This will make a larger part of the city available to any plan to ride a bike rather than a car.  E-bikes don't need special charging stations, plus they can contribute to better health by exercise and less pollution.  It's a win-win so long as we design our cities so there's not a fight between motorized vehicles and bikes.

silicon batteries next step from lithium ion?

Batteries made with silicon instead of graphite — the commonly used material in battery anodes today — have been shown to enable significantly higher energy density and faster charging. 

“Silicon anode has 10 times higher energy density than graphite,” according to CEO Kang Sun of Amprius Technologies, one of the companies working on the technology.

“We’ve demonstrated that we can charge to 80 percent in under six minutes,” added Jon Bornstein, the company’s chief operating officer. Amprius is already working with Airbus, the U.S. Army, AeroVironment and BAE Systems on early iterations of its silicon-anode batteries.

 Is it easy to switch battery production plants to a new method easily?  I certainly hope so.

How many people ride their bike to work?

 "Despite all of the recreational opportunities for bicyclists within the Black Hills region, bicycling is
the least utilized method of commuting to work in the Rapid City Area. According to American
Community Survey (ACS) data for 2017, only 0.4% of residents commute to work via bicycling.
Pedestrians made up 3.7% of work commuters, and transit riders made up 0.6% of work
commuters."

At least here in South Dakota, not many people bike to work.  While Rapid City has a very nice bike trail that winds along the creek, much of the city has no real bike trail, so you're fighting cars in many places.  Hopefully bikes can be given a higher transportation status so more people will choose that method, weather permitting, of course.

We can live without cars!

"If there was efficient mass transit so that everyone can sort of theoretically get around, I would say [that] is pretty close to what is in place in Europe," Fulton told Salon, where Europeans have managed to maintain a functioning society despite using cars far less often than Americans.

Yet Europe is still an imperfect example because even there, automobiles are so ubiquitous that they still consume a large chunk of transportation time. The key difference is that while Americans overwhelmingly rely on cars to get around, Europeans have an infrastructure that mixes cars more robustly with alternatives like buses, trains, bicycling and even walking. Fulton noted that the environmental situation in Europe is better than that in America because Europeans rely less on cars, which suggests that there are lessons from their experience.

This is a good article that goes into many advantages of reducing our reliance on cars, such as the environment, job advancement, etc.  It can be done as other countries have already shown.
