<span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;">Everywhere you look, there’s a different solar power project going on, and one of the most interesting are solar roads. From American startups to French prototypes and beyond, solar roads have gone through their trials and tribulations. Where’s the technology at? Will we be seeing them in the near future? Let’s get into the details about their place in the world, and if they’re really worth it.</span>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">It’s a slow-moving process on the homefront. Attempted solutions, such as </span>[https://www.engadget.com/2016/07/04/solar-road-technology-comes-to-route-66/ Solar Roadways’ Route 66 experiment]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">, </span>[https://news.nationalgeographic.com/2017/07/chasing-genius-solar-roadways/ aren’t offering enough benefits]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">to justify </span>[https://www.sciencealert.com/solar-roads-that-could-power-the-entire-us-are-on-the-horizon paving the entire United States]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">in solar road tiles. These roads offer other features, but all are irrelevant to the main point: These roads are not practical.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;">There’s safety concerns along with high cost issues. So far, solar roads aren’t a viable solution in the United States. They’re not the only country to give it a fair shot, though. China, France, and the Netherlands have been undergoing their own projects.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; font-weight: 700; white-space: pre-wrap;">The Shandong Project in China</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">In the quest to find more uses for solar panels, China opened a one kilometer-long solar road. The future of solar roads doesn’t look too good: China’s data suggests that</span>[http://www.slate.com/articles/health_and_science/science/2017/12/solar_roads_are_almost_definitely_not_the_future.html it’s not a viable plan]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">to bring in large annual numbers of generated electricity.</span><br/>

Solar power continues to drop in price around the globe, but so far, there’s not a lot of headway with</span>[https://powerscout.com/home-solar/solar-panel-costs low-cost solar road panels]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; font-weight: 700; white-space: pre-wrap;">The French Wattway</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Dubbed by ARS Technica as the “</span>[https://arstechnica.com/cars/2016/12/worlds-first-solar-road-opens-in-france/ World’s first solar road]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">,” France took the plunge in 2014. It was strategically placed in the village of Tourouvre au Perche in Normandy, in a “Not-so-sunny village.” The initial goal was to divert all solar power from the road to the village’s street lights as a sort of “baptism by fire” of solar roads.</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">The verdict ends up sounding like a broken record: solar roads are currently far too expensive to implement. If nothing else, based on the </span>[https://www.ucsusa.org/clean_energy/our-energy-choices/renewable-energy/environmental-impacts-solar-power.html#.WlVgAK6nHIU environmental impact associated with producing solar panels]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">and solar technology, solar roads </span>[https://www.vox.com/2014/5/14/5717036/should-we-cover-all-our-roads-with-solar-panels aren’t as practical as they sound]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">, but that doesn’t mean they’re done for.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; font-weight: 700; white-space: pre-wrap;">The Dutch Solar Bicycle Path</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">As a slightly different approach, </span>[https://www.triplepundit.com/2016/01/looking-at-the-dutch-solar-bike-path-after-one-year/ designed for cyclists instead of automobiles]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">, the Dutch created a solar pathway. Results proved to be far more favorable for their efforts (in terms of durability), after the top layer of the road came off in its first year, forcing them to replace it with a more durable material. Despite the issue with laboratory-tested road panels, it gave them insight.</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Still, the numbers don’t add up. The money spent on SolaRoad, the Netherland’s bicycle path in question, </span>[https://www.triplepundit.com/2016/01/looking-at-the-dutch-solar-bike-path-after-one-year/ could have purchased 520,000 kilowatts of electricity]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">. Instead, it generated a meager 3,000 kilowatts in its first year. Durable, yes. Sustainable? Not quite.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; font-weight: 700; white-space: pre-wrap;">Will We See Solar Roads Expanding?</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;">In short, it’s unlikely that we’ll see these projects popping up everywhere. Many countries have implemented their own attempts at solar panel roadways, and none have found a return on investment to date.</span><br/>

<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">Apart from the costs, there are safety concerns (since you’re riding on textured glass). Eric Weaver from the Department of Transportation (DoT) in the US states, “</span>[https://www.greentechmedia.com/articles/read/department-of-transportation-official-discusses-solar-roadways#gs.wdeIIVo We can’t say that it would be safe for roadway vehicular traffic.]<span style="background-color: transparent; font-size: 11pt; font-family: Arial; font-variant-numeric: normal; font-variant-east-asian: normal; vertical-align: baseline; white-space: pre-wrap;">”</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;">Solar roads are designed to melt snow, power street lights, and in the case of the popular “Solar Freakin’ Roadways,” even eliminate the need to paint asphalt with white and yellow lines, using LED lights in their place. While the features seem great, it’s a wildly bad investment across the board.</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; font-weight: 700; white-space: pre-wrap;">Inspired, Yet Impractical Tech</span><br/>

<span style="background-color: transparent; font-family: Arial; font-size: 11pt; white-space: pre-wrap;">As of right now (2018), solar roads are still years behind where they need to be. We won’t be seeing them in densely-populated areas anytime soon; not unless the production cost plummets.</span><br/>
