87% I'm sure the oil companies are gearing up to being export focused, rather than domestic consumption. This will result in a much needed balance in trade. On a side note, it's disgusting how the electric utilities are using their connection in state government to thwart the roof top solar panel industry. Nevada Power bribed enough politicians to get the rate the utilities must pay for the electricity that homeowners pore back into the grid, lowered substantially. Moving the goal post after thousands had already invested. Regardless of the spin, this was nothing more than an effort to slow down a growing industry that threatened their market share. I now wonder what similar efforts will be underway by the oil companies and gas station owners. Anyway, as Tesla and others continue to innovate, that 87% is right around the corner. The market for gasoline will be the developing countries. http://www.bloomberg.com/news/articles/2016-08-15/how-many-of-our-vehicles-could-be-electric-how-does-87-strike-you With all the limits on electric vehicles—battery life, cost, the availability of charging stations—you might expect that at most 50 percent of the vehicles on U.S. roads could be replaced by more-sustainable cars. Buckle up: It’s 87 percent, MIT reckons, in a study published Monday in the journal Nature Energy. Such a proportion, if it were the case today, would lead to a 60 percent reduction in total U.S. gasoline consumption and a 30 percent decrease in the 1.8 billion metric tons of greenhouse gas emissions emitted by all American transportation in 2014.1 Transport represents 26 percent of America’s total greenhouse gas emissions. That's huge. It's also a thought experiment. Currently 0.7 percent of vehicles in the U.S. are electric, and plug-in electric vehicle sales declined 17 percent from 2014 to 2015. But it's an interesting one. The findings represent a “technical potential” that shows how many households could start living more sustainably now, said Professor Jessika Trancik, who led the study. For instance, in a two-car household, having one electric car and one conventional vehicle could meet drivers’ needs across the country and significantly increase the number of electric vehicles on the road. Cleaner Cars The researchers found that more affordable electric vehicles, such as the Ford Focus Electric and the Nissan Leaf, could meet our energy and affordability needs if people recharged their cars just once daily, either overnight at home or during the day at work. Then the scarcity of public charging stations wouldn't be as pressing. And although electric vehicles’ sticker prices are higher, the researchers concluded that their operating costs would be lower than for conventional cars. This would make the overall costs comparable. The study noted that rural areas had a slightly smaller adoptive potential than urban areas but found similar potential across different types of cities, ranging from more compact cities such as New York and to more sprawling ones like Houston. Close all those tabs. Open this email. Areas with more extreme temperatures—using heating or cooling systems lowers an electric vehicle’s driving range—and where such larger vehicles as trucks and SUVs are more common will be less likely to increase their use of EVs, said Jeremy Michalek, an engineering professor at Carnegie Mellon and director of the university’s vehicle electrification group. Michalek, who wasn’t involved in the study, said he prefers to focus on the most challenging days for vehicles rather than the average conditions. “You buy a pickup truck even though most days you’re not loading it full of stuff. You buy it because you have to move some things a few days a year,” he said, noting that most electric vehicles are small or midsize cars. Trancik acknowledged the issue. The researchers used two data sets, one with second-by-second driving behavior based on GPS data collected from Texas, Georgia, and California and a national data set based on travel surveys. They accounted for different regional driving and weather conditions to conclude that daily energy consumption is distributed similarly across cities for most vehicles. Trancik hopes the research will show how the potential for EV adoption could exceed even 87 percent. She said the researchers are developing an app based on their model that could tell car shoppers how many days per year an electric vehicle could meet their needs and advise two-car households on which type of car, EV or regular, they should use on high-energy-consumption days. Regardless of advances in technology and the addition of charging stations, there will always be days on which electric vehicles can’t get the job done. For these, Trancik said, there would need to be better car-sharing services or advancements in other environmentally friendly cars that could fill in the gaps. She also pointed to the need for further quantitative research on EVs. Common sense isn’t enough. Common sense leads people to conclude either that the potential is high or low. You have extreme views on both ends,” she said. “It’s important to unpack that question and ask research questions that we can answer quantitatively.” |

Pat, EV is nice, but it would take more than a few days to effect, so it doesn't work for most cons.

I could get by year round with a car that was driven less than 120 miles per day. 95% of the time on one that is driven about 15 - 20 miles per day. How many worker bees have two cars that are driven to work and back, less than 20 miles per day? As far as longer commutes until more recharge is available, publuc transit. We will soon see a massive shift in infrastructure and community planning. |

Pat, I don't argue with your premise, just don't see it happening in a short period of time. Logic and cars have a very tenuous relationship a best.

I can say this owning an EV. Still really enjoying driving my plug in hybrid Ford Fusion with total MPGe holding at 60 going on 3 months and only driving my 05’ oil leaking diesel 1 ton when needed for work which is most of the time unfortunately and taking it to the mechanic next week that has fixed most of problems Ford Powerstroke 6.0 have. If the cost is another “3k this time” it will become a target at a good local machinegun shoot free of charge. The sad thing and reality is it would need to be replaced costing probably more and taking a deep breath having sucking it up.. |

I hope we will see the battery improvements in other areas, like in regular 12v gas car batteries. There's no reason to continue making the old lead acid ones is there? Cut the weight and size |

Battery technology is changing gone, there has been a lot of research dollars focused on it. |

I think I have posted a video somewhere in here where someone made a car battery out of capacitors. Let me see if I can find it again. Replacing My Car Battery with Capacitors! 12V BoostPack Update https://www.youtube.com/watch?v=z3x_kYq3mHM |

The big issue is how is the electricity generated to power them. Unless it's hydroelectric or solar, they arent exactly green. |
