Green Reservation
We hear the phrase “we’re all in this together” a lot these days. And that certainly applies to preserving our precious natural resources. This week, we see how those with the longest ties to our natural history are taking bold steps to ensure a clean future.
The Cherokee nation is located in a 9,000 square mile area of northeastern Oklahoma. Unlike other reservations, Cherokee tribal land is checkerboarded in and around state jurisdictions, and Cherokee citizens are very much a part of the local communities. So maintaining their own civic infrastructure and preserving Cherokee culture while keeping pace with modern society is a vital task.
Chuck Hoskin, Jr.: "Well, our belief, and it’s one that’s held our people together for generations, is that we look seven generations into the future. We look at what our actions today are doing for generations from now. And I think in the world we live in today, it’s important to reduce our carbon footprint, to look for avenues to explore green energy, and I’m standing next to our solar canopy, which is one of our key initiatives to meet that objective, reduce that carbon footprint -- think ahead to future generations, make sure that this reservation that we’re on right now, is going to be clean and pristine. Hopefully cleaner as we go by, thanks to these kinds of initiatives for generations into the future."
The Indian Nations Council of Governments is also home to the Tulsa Area Clean Cities Coalition, easing the way for the Cherokee Nation and other tribal partners to team up through clean cities on a number of clean vehicle projects.
This solar canopy, completed in 2017, currently houses eight, free, public level 2 electric car charging outlets at the Cherokee Nation's main administrative complex.
It generates up to 58,000 kilowatt-hours per year and augments grid power supplied to the buildings when not used for charging vehicles.
When it was installed, there were actually very few electric vehicles registered in the area, but in a classic case of “build it and they will come,” the local EV population, and demand for charging, has grown rapidly.
Chad Hasha: "Since we’ve installed this canopy, we’ve seen both the number of electric vehicles utilizing it increase. Actually we have to increase the number of stalls available. And we have also since that time purchased a number of electric vehicles to supplement our tribal fleet operations."
Once complete, the solar site’s electric vehicle charging capacity will be doubled to 16.
The Cherokee Nation’s EV Initiative also includes four DC fast chargers and additional level twos, installed or planned for tribal lands throughout the area, as well as a significant investment in public transportation.
Chuck Hoskin, Jr.: "We have an electric school bus here in the Cherokee nation, I think it’s the first in the region, and we have some electric transit buses, which we think are the first for a rural-based transit system in the United States."
With just 2000 fluent speakers remaining, attrition of tribal elders through natural causes and from the COVID pandemic losing many tribal elders to COVID has threatened the very viability of the Cherokee language for the future.
This electric school bus transports students in the Cherokee Nation’s groundbreaking language immersion program, where new generations of native speakers are being trained to teach others and keep this vital link to the past alive.
These newly-arrived Proterra electric transit buses carry bilingual signage throughout the interior to act as teaching tools, and as a reminder to all of the importance of not just preserving, but continuing Cherokee traditions.
Chuck Hoskin, Jr.: "If you go elsewhere in the reservation, you’ll see community organizations that are really the hub and the lifeblood of these little communities that again have existed since before the state of Oklahoma was here."
We have to connect people, from home to work and home to health centers. Doing that in an environmentally sustainable way is important, and these transit buses are a big part of that.
And there’s a little bit of a teaching moment about where does energy come from, how do we harness something like the sunlight to power this little community. So, these sorts of things, I think are sparking some interest among young people, which is of particular interest to me, because they’re the ones who are going to take on leading this nation in the future.
Waste Not Want Not
JOHN DAVIS: The concept of renewable fuels made from non-petroleum sources has a long history. Indeed, over the last four decades, we’ve seen how renewable fuels have been used with great success as sustainable alternatives to traditional gasoline and diesel. So, we thought we’d check out three examples where fast responses rely on reliable fuels, and see how green solutions are leading the way forward!
Our first stop is Vancouver, Washington, where the city’s fire department has made the switch to renewable diesel for its 27 fire trucks, engines and EMS squads. Also called RD or R99, renewable diesel is not the same as biodiesel. It is refined from plant oils and animal fats to become chemically identical to conventional diesel, which biodiesel is not. R99 performs better in cold weather and can be used without modification in any diesel vehicle.
The process of burning carbon soot out of a conventional diesel’s exhaust particulate filter, known as regen, can take a truck out of service for several hours over the course of a week. Using R99 instead, less soot builds up, increasing the regen intervals and requiring a less intense regen procedure.
The Vancouver Fire Department responds to 51,000 emergency calls each year, so every minute of downtime in the shop can be the difference between life and death.
CHUCK WINKLER: These vehicles have to work 100% of the time, all the time. So, reliability is our number one… Safety and reliability is our number one goal here, and R99 has really helped with that 100% reliability.
JOHN DAVIS: Then there is UPSA, one of world’s largest delivery fleets with 125,000 vehicles. UPS obtains nearly 40% of their transportation fuel from low-carbon sources, and has driven over 4 billion miles on alternative fuels. They are also the largest consumer of renewable natural gas in the transportation industry.
AL MURAT: While electric cars, electric vehicles, Es are going to play an important role, right now CNG and RNG is one of the important bridge points to getting there. So, rather than wait for those alternatives to grow in technology, we’re leveraging RNG right now as one of the best solutions.
JOHN DAVIS: RNG, also known as biomethane, is derived from decomposing organic matter at landfills, wastewater treatment plants, livestock farms, and food production facilities. RNG is interchangeable with conventional natural gas and can be used in existing pipelines.
This renewable natural gas fueling station at UPS’ eastern zone hub in Pennsylvania, is the largest in the UPS network. It services 220 tractors and 150 delivery vehicles, displacing 8 million gallons of diesel fuel per year. Renewable natural gas literally turns waste into clean energy, and is helping big brown deliver on its longtime commitment to go green.
Whenever a green flag drops, the extreme conditions of motorsports competition have long served as a testing ground and accelerator for technological development, and that now includes sustainability. Race organizers around the world have set a goal of achieving carbon neutrality by 2030, and aim to reduce race-related emissions by 30%. The world endurance challenge series, which includes the 24 Hours of Le Mans, now runs on a 100% renewable fuel derived from grape residue.
In a sport where lightning fast reflexes and instant throttle response can mean the difference between first place and also ran, a stable, power-dense fuel is a must, and you gotta admit, running race cars on wine is pretty dang cool!
These three sustainable petroleum substitutes are all winning formulas, ones we will be keeping an eye on.
