Everybody Wants EV Charging Stations. Almost Nobody Wants to Build Them.
By Jeremy Deaton
A driver planning to make the trek from Denver to Salt Lake City can look forward to an eight-hour trip across some of the most beautiful parts of the country, long stretches with nary a town in sight. The fastest route would take her along I-80 through southern Wyoming. For 300 miles between Laramie and Evanston, she would see, according to a rough estimate, no fewer than 40 gas stations where she could fuel up her car. But if she were driving an electric vehicle, she would see just four charging stations where she could recharge her battery.
The same holds true across the country. Gas stations outnumber public charging stations by around seven to one. It's no wonder people get so nervous about driving an electric car.
Numerous studies have shown that consumers steer clear of EVs because they worry about the lack of charging stations. Studies also show that consumers are more likely to buy an electric car when they see stations around town. While fears about range anxiety are largely unfounded — even the cheapest EVs sport enough range to serve nearly all of a driver's needs — the paucity of charging stations is a real concern on longer trips, and it is deterring consumers from going all-electric.
To be clear, it's not just consumers who want to see more chargers. Charging stations are a boon to automakers, who want to sell electric cars, as well as to power utilities, who want to sell more electricity. Some utilities and automakers are investing huge sums into setting up charging stations — including Volkswagen's commitment to spend $2 billion on EV charging infrastructure as part of their settlement over the diesel emissions scandal. But by and large, automakers and power companies are not putting a lot of money towards charging infrastructure.
"I think the biggest problem with charging stations is there is no one responsible for installing charging stations," said Nick Sifuentes, executive director at Tri-State Transportation Campaign. "So you see some automakers, like Tesla, installing charging stations. You see charging stations occasionally getting put out as part of a municipal planning process," he said, "but for the most part, there is no one entity or group that feels responsible for that duty."
Power utilities have a big interest in EVs. Despite continued economic growth, demand for electricity has stayed flat over the last decade, as businesses slash energy use and consumers switch to more power-thrifty appliances — LED light bulbs, flat-screen TVs, high-efficiency washers and dryers. EVs could drive up the demand for electricity, throwing a lifeline to power utilities. And yet, these companies largely aren't building charging stations.
"For power utilities, the question is whether they see it as something that's actually in their bailiwick or not," Sifuentes said. Policymakers have not directed utilities to build out EV infrastructure, and with so few electric cars on the road, utilities are unlikely to take it upon themselves to start building charging stations.

"The problem is that the charging infrastructure doesn't have a viable business model yet," said David Greene, a professor of civil and environmental engineering at the University of Tennessee. "Although, there are some companies who are working on it really hard."
Private firms like EvBox and ChargePoint are looking to radically expand the number of available charging stations, but these plans depend on exponential growth in the sale of EVs. ChargePoint is looking to add 2.5 million charging stations to its global network of just 50,000, a goal it said is based on a "conservative view" of future EV sales. EvBox, meanwhile, is aiming for 1 million new charging stations. A spokesperson noted this target is "at least partly dependent on the number of electric vehicles on the road," though he was similarly bullish on the growth of EVs. Analysts expect EV sales to increase dramatically in the coming years, though major roadblocks stand in the way of future adoption.
Even if EV sales take off and charging stations proliferate, barriers will remain. Making EVs more viable means installing not just more chargers, but more fast chargers that allow drivers to take long journeys. The difference between a fast charger and a slow charger is the difference between a family stopping for coffee while they refuel their car and a family stopping overnight.

"It's 180 miles from Knoxville to Nashville. Supposedly there's a [direct current] fast charger at a Cracker Barrel in Cookville, which is almost exactly halfway, but it almost never works," Greene said. "The fact that the range is limited and the recharging time can be quite long if one does not have access to fast charging, that's another problem."
There is also the fact that the technology isn't standardized. Different cars use different plugs. Ford and GM use one kind. Tesla uses another. Fast charging requires a different kind altogether. So, while charging stations dot the country, not every station meets every driver's needs. Until manufacturers arrive at an industry standard — or policymakers mandate that standard —
"charging stations are going to need to have two or three different types of plugs, and people will need to be able to charge at different speeds because their car might not have a supercharger," Sifuentes said.
Sifuentes believes that policymakers have a key role to play in building out charging stations. "They have to actually put in place laws and incentives that encourage the development of the necessary infrastructure, and I think that takes place in two ways," he said. "One, encouraging utilities to do that. But also, I think we can't ignore the role that public transit plays here."

New York City, he said, has pledged to switch to all-electric buses by 2040. "That means they're going to have to put some serious charging infrastructure in place," Sifuentes said. "If there's a charging location that has to be put in because buses need to charge there but that's available for private use as well, great."
In addition to building public charging infrastructure, governments can also encourage the development of private charging infrastructure. Policymakers in Iowa and Austin, Texas, for example, are working to lower barriers to setting up charging stations, allowing private firms, as opposed to power utilities, to resell electricity. "I think the other role that policymakers have to play here is they have to actually put in place laws and incentives that encourage the development of the necessary infrastructure," Sifuentes said.
In Norway, where EVs account for around a third of all new car sales, the government has gone a step further. The government is installing a fast charging station every 30 miles on main roads. EV drivers can get free charging at public stations in addition to free parking and free access to toll roads. Sifuentes said these kinds of policies are needed to spur the growth of EVs and support the installation of EV charging stations.
"We're absolutely on the tipping point," Sifeuntes said. "The more that we see EVs rolling out, the more and more it's going to look like the right move to be putting this infrastructure in place."

If weather is your mood, climate is your personality. That's an analogy some scientists use to help explain the difference between two words people often get mixed up.
Size Matters<p>Climates are a bit like woven tapestries. The big picture is important, no question. But so are all the seemingly minor details found inside the larger whole.</p><p><a href="https://research-information.bris.ac.uk/en/persons/tommaso-jucker" target="_blank">Tommaso Jucker</a> is an environmental scientist at the University of Bristol. In an email, Jucker says he'd define the term microclimate as "the suite of climatic conditions (temperature, rainfall, humidity, solar radiation) measured in localized areas, typically near the ground and at spatial scales that are directly relevant to ecological processes."</p><p>We'll talk about that last bit in a minute. But first, there's another criteria to discuss. According to some researchers, a microclimate — by definition — must differ from the larger area that surrounds it.</p><p><a href="https://www.cfc.umt.edu/research/paleoecologylab/publications/Davis_et_al_2019_Ecography.pdf" target="_blank">Forests</a> provide us with some great examples. "The climate near the ground in a tropical rainforest is dramatically different from the climate in the canopy 50 meters [164 feet] above," says University of Montana ecologist <a href="https://www.cfc.umt.edu/personnel/details.php?ID=1110" target="_blank">Solomon Dobrowski</a> in an email. "This vertical gradient among other factors allows for the staggering biodiversity we see in the tropics."</p><p>Likewise, scientists observed that a 2015 partial <a href="https://animals.howstuffworks.com/insects/bees-stopped-buzzing-during-2017-solar-eclipse.htm" target="_blank">solar eclipse</a> caused the air temperature of an Eastern European meadow to <a href="https://rmets.onlinelibrary.wiley.com/doi/full/10.1002/wea.2802" target="_blank">change more dramatically</a> than it did in a nearby forest. That's because trees provide not only shade, but their leaves also reflect solar radiation. At the same time, forests tend to reduce wind speeds.</p><p>All those factors add up. A 2019 review of 98 wooded places — spread out across five continents — found that forests are 7.2 degrees Fahrenheit (4 degrees Celsius) <a href="https://natureecoevocommunity.nature.com/posts/47363-forests-protect-animals-and-plants-against-warming" target="_blank">cooler on average</a> than the areas outside them.</p><p>Now if you hate the cold, don't worry; there's a cozy exception to the rule. According to that same study, forests are usually 1.8 degrees Fahrenheit (1 degree Celsius) warmer than the external environment during the wintertime. Pretty cool.</p>
A Bug's Life<p>When does a microclimate stop being, well, micro? In other words, is there a maximum size we should be aware of when discussing them?</p><p>Depends on who you ask. "In terms of horizontal scale, some have defined 'microclimate' as anything that is less than 100 meters [328 feet] in range," Jucker says. "I'm personally less prescriptive about this."</p><p>Instead, he says the "scale at which we want to measure [a particular] microclimate" ought to be "dictated" by the questions we're trying to answer.</p><p>"If I want to know how temperature affects the photosynthesis of a leaf, I should be measuring temperature at centimeter scale," Jucker explains. "If I want to know if and how temperature affects the habitat preference of a large, mobile mammal, it's probably more relevant to capture temperature variation across [tens to hundreds] of meters."</p><p>For instance, solitary plants have the power to generate itty-bitty microclimates. Just ask <a href="https://www.colorado.edu/geography/peter-blanken-0" target="_blank">Peter Blanken</a>, a geography professor at the University of Colorado, Boulder and the co-author of the 2016 book, "<a href="https://amzn.to/2XN6FT8" target="_blank">Microclimate and Local Climate</a>."</p>
The urban heat island effect is a good example of how microclimates work. NOAA
Microclimates on a Grand Scale<p>It's no secret that our planet is going through some rough times at the macro level. The global temperature is <a href="https://climate.nasa.gov/vital-signs/global-temperature/" target="_blank">climbing</a>; nine out of the <a href="https://www.noaa.gov/news/2019-was-2nd-hottest-year-on-record-for-earth-say-noaa-nasa" target="_blank">10 hottest years on record</a> have occurred since 2005. And by one recent estimate, roughly 1 million species around the world are <a href="https://ipbes.net/sites/default/files/2020-02/ipbes_global_assessment_report_summary_for_policymakers_en.pdf" target="_blank">facing extinction</a> due to human activities.</p><p>"One of the big questions that ecologists and environmental scientists are trying to answer right now is how will individual species and whole ecosystems respond to rapid climate change and habitat loss," says Jucker. "...To me, [microclimates are] a key component of this research — if we don't measure and understand climate at the appropriate scale, then predicting how things will change in the future becomes a lot harder."</p><p>Developers have long understood the impact small-scale climates have on our daily lives. <a href="https://science.howstuffworks.com/environmental/green-science/urban-heat-island.htm#pt0" target="_blank">Urban heat islands</a> are cities that have higher temperatures than neighboring rural areas.</p><p>Plants release vapors that can moderate local climates. But in cities, natural greenery is often scarce. To make matters worse, plenty of our roads and buildings have a bad habit of absorbing or re-emitting heat from the sun. <a href="https://www.google.com/books/edition/Microclimate_and_Local_Climate/LHUZDAAAQBAJ?hl=en&gbpv=1&bsq=urban%20heat%20island" target="_blank">Vehicle emissions</a> don't exactly help the situation.</p><p>Still, it's not like Boston or Beijing are thermal monoliths. Sometimes, the documented temperatures <a href="https://e360.yale.edu/features/can-we-turn-down-the-temperature-on-urban-heat-islands" target="_blank">within a single city</a> vary by 15 to 20 degrees Fahrenheit (8.3 to 11.1 degrees Celsius).</p><p>That's where metro parks and city trees come in. They have nice cooling effects on nearby neighborhoods. "Several cities around the world have developed programs to increase urban green spaces," says Blanken. "Tree planting programs and green roof programs, have been shown to lower surface temperatures, decrease air pollution and decrease surface water runoff (urban flash-flooding) in urban areas."</p>

If asked to recall a hurricane, odds are you'd immediately invoke memorable names like Sandy, Katrina or Harvey. You'd probably even remember something specific about the impact of the storm. But if asked to recall a heat wave, a vague recollection that it was hot during your last summer vacation may be about as specific as you can get.

One of the challenges of renewable power is how to store clean energy from the sun, wind and geothermal sources. Now, a new study and advances in nanotechnology have found a method that may relieve the burden on supercapacitor storage. This method turns bricks into batteries, meaning that buildings themselves may one day be used to store and generate power, Science Times reported.
Bricks are a preferred building tool for their durability and resilience against heat and frost since they do not shrink, expand or warp in a way that compromises infrastructure. They are also reusable. What was unknown, until now, is that they can be altered to store electrical energy, according to a new study published in Nature Communications.
The scientists behind the study figured out a way to modify bricks in order to use their iconic red hue, which comes from hematite, an iron oxide, to store enough electricity to power devices, Gizmodo reported. To do that, the researchers filled bricks' pores with a nanofiber made from a conducting plastic that can store an electrical charge.
The first bricks they modified stored enough of a charge to power a small light. They can be charged in just 13 minutes and hold 10,000 charges, but the challenge is getting them to hold a much larger charge, making the technology a distant proposition.
If the capacity can be increased, researchers believe bricks can be used as a cheap alternative to lithium ion batteries — the same batteries used in laptops, phones and tablets.
The first power bricks are only one percent of a lithium-ion battery, but storage capacity can be increased tenfold by adding materials like metal oxides, Julio D'Arcy, a researcher at Washington University in St. Louis, Missouri, who contributed to the paper and was part of the research team, told The Guardian. But only when the storage capacity is scaled up would bricks become commercially viable.
"A solar cell on the roof of your house has to store electricity somewhere and typically we use batteries," D'Arcy told The Guardian. "What we have done is provide a new 'food-for-thought' option, but we're not there yet.
"If [that can happen], this technology is way cheaper than lithium ion batteries," D'Arcy added. "It would be a different world and you would not hear the words 'lithium ion battery' again."
One of the concerns about a warming planet is the feedback loop that will emerge. That is, as the planet warms, it will melt permafrost, which will release trapped carbon and lead to more warming and more melting. Now, a new study has shown that the feedback loop won't only happen in the nether regions of the north and south, but in the tropics as well, according to a new paper in Nature.
