Wholesale fruit and veggie distributor Four Seasons Produce in Lancaster County, Pennsylvania knew that efficiency all comes down to business. "Our journey started with, 'We need to cut costs,'" said Randy Groff, Four Seasons' director of facilities and energy. It didn't take the company long to turn to their utility bill as a potential source of savings.

Groff used to be "director of facilities," but energy was added to his title in 2010. That's how important energy costs are to the bottom line of a business that runs a 400,000-square-foot warehouse where fruits and veggies have to be kept cool. Storage temperatures range from 28 to 55 degrees Fahrenheit, depending on the product.

America's rural-based produce shipment companies like Four Seasons play a vital role in ensuring a steady supply of fresh food across the country, linking agricultural heartlands to urban centers. However, the sheer scale of agricultural production and distribution necessitates significant energy inputs - and plenty of hard work.

It's a "low-margin, fast-paced" business. "You have to sell a lot to make a lot," Groff said.

Groff is a 28-year employee for the family-owned Four Seasons, which started from the back of a pick-up truck at a farmer's market and now has 900 employees. The company distributes organic and conventional produce to independent retailers and chains throughout the Mid-Atlantic and Northeast. Its family of companies includes a logistics operation, a truck fleet, and imports.

Previously, Groff worked as an electrician, and he combines that experience with his "love of data" to determine how much energy and money the company is saving.

The company started with lighting retrofits and slowly worked up to larger and larger energy projects. Employees got excited about sustainability and formed a company-wide Green Team. "It just kind of took off," Groff said.

Two solar projects now produce about 35 percent of Four Seasons' energy use. Solar arrays cover the entire roof of the warehouse.

Four Seasons installed its first 1.3-megawatt solar array in 2018, utilizing a 26 percent solar investment tax credit. They recently added a second, 1.7-megawatt array, using the federal tax credit and depreciation at 37 percent. The tax credits that funded these upgrades were made available through the Inflation Reduction Act (IRA).

"Between those two, it's over a million dollars of savings just in the tax depreciation and the tax credit," Groff said. Four Seasons also received their utility's maximum rebate, adding another half-million in savings.

Another energy efficiency project added VFDs (Variable Frequency Drives) in the thousands of motors used in warehouse refrigeration. VFDs control motor speed and torque by varying the frequency of the electricity coming into the motor.

Rebates on VFDs and solar panels help make the return on investment "a no-brainer," Groff said. He suggests businesses pay attention to rebate line items on utility bills. "If you're not taking advantage of the rebate program, you're actually paying us to do it," he said.

Groff also recommends that businesses talk up-front to their utility about interconnection requirements when considering solar. It took six months after installation for Four Seasons' latest array to be fully interconnected.

During the day, the huge warehouse is totally "off-grid," Groff said. Live stats on the company's website show energy usage. "It's exciting to be able to see that graph go to zero and stay at zero, for about six hours," he said. "Come three o'clock in the afternoon, the sun's starting to go down, and we start going back on the grid."

Groff is currently exploring thermal storage as a method of capturing additional energy produced during peak sunlight and using it to offset the warehouse's peak demand hours in the middle of the night.

Four Seasons has cut its electric bills by 60 percent since 2005. It was the first refrigerated warehouse in the country to earn an Energy Star and the company's truck fleet plans to increase mileage through the EPA's SmartWay Transport Partnership. The result isn't just a reduced carbon footprint for Four Seasons. The savings ensure the integrity of America's food supply chain.

"It's funny, because it didn't really start as 'being sustainable,'" Groff said. "But yet it turned into a sustainable practice, because we've been doing it for so long."

Nevada climate advocates say the impacts of climate change are only getting worse in the Silver State. They're now demanding Congress make it a priority and address what they call a dire situation.

Rep. Dina Titus, D-Las Vegas, introduced the Extreme Weather and Heat Response Modernization Act earlier this year and said it will provide the Federal Emergency Management Agency the "flexibility" to expand mitigation measures against extreme heat, which includes cooling centers. The legislation has made it out of the House Transportation and Infrastructure Subcommittee with bipartisan support. Titus said if it doesn't pass this term, she vows it'll be one of the first pieces of legislation she will introduce in the upcoming session. Titus says extreme heat and drought go hand in hand.

"The Colorado River contributes greatly to our economy; $104 trillion is the annual economic activity that comes from things that relate to the Colorado River," Titus said. "It sustains 16 million jobs throughout the seven states that are part of the Colorado River Basin," she explained.

Titus contends that keeping the river and Lake Mead sound will be a positive for tourism, jobs and agriculture in Nevada and throughout the Western U.S. This week the U.S. House passed the Water Resources Development Act which Titus says includes provisions that will help sustain water resources in Nevada. The bill faced little opposition and now heads to the Senate, before being sent to the president.

Roberto Renteria, a member of the nonprofit Make the Road Nevada, said this year the Silver State endured increased extreme weather events such as record-breaking wildfires and relentless heat waves, making it difficult for folks to endure.

"These are not climactic events, they are urgent calls for action. The wildfires have burned more than 58,000 acres in our state, putting at risk our communities, wildlife and economic vitality," he said.

Renteria added the extreme heat simply cannot be ignored and contends the public health crisis disproportionately impacts those who work outside as well as those with low socio-economic status.

The Oregon Department of Fish and Wildlife and its partners have received a $4.5 million grant from the federal America the Beautiful Challenge program to restore more than 2,000 acres of oak and prairie land up and down the Willamette Valley. The project will draw on partnerships across 22 public, private and tribal sites to restore native plant species such as camas, and reduce fuel for wildfires.

Lindsay McClary, restoration ecologist with the Confederated Tribes of Grand Ronde, said these oak and prairie lands have deep cultural significance as a source of food, medicine and hunting grounds.

"Really, these landscapes were maintained by traditional tribal practices and they were relied upon as such. So restoring these habitats is really like restoring cultural life ways to the Willamette Valley," she explained.

Once widespread, only 7% of oak habitat and 1% of prairie habitat remain in the state. This is in part due to the impacts of fire suppression, so one piece of the restoration plan is prescribed burning.

McClary said Kalapuya fire practices shaped the Willamette Valley, and that removal of fire has invited in too much plant growth, making the area more susceptible to wildfires, and added that oak and prairie habitats require constant disturbance, and the role of fire in ecosystems is often misunderstood.

"I think this project is really going to help shift and change that social conversation where we can embrace fire as an important tool when it's done correctly," she continued. "And it's going to lead to a reduction of those catastrophic wildfires that nobody wants to live through and experience."

Oak trees are known to support biodiversity like few other trees are able to. From large wildlife who graze on the acorns down to the many species of fungus that grow with them, oak trees are known to support at least 2,300 species. McClary said slowing down and observing the trees, will help people more fully appreciate them.

"From top to bottom, there's a whole little city of creatures that are existing or relying on a single oak that we really just don't notice," she said.

Christmas, it turns out, is for the birds, at least for those that will be counted this year in the National Audubon Society's Christmas Bird Count.

The nearly monthlong bird count takes place around the country. Birders will go through a circled area with a 15-mile radius, counting the number of birds they see or hear.

Steve Sheffield, professor of biology at Bowie State University and vice president of the Maryland Ornithological Society, said the data gathered across the country will help map the trends and movements in bird populations.

"You can look at the population trends of each of the species and see where they're headed, whether their trajectory is up or down or whether they're stable," Sheffield outlined. "You can also look at where you are seeing the numbers. You're getting an idea of how the birds are moving due to climate change."

For counters who can identify bird calls, Sheffield noted they only need to hear a bird in order to count it, which helps with species flying silently, such as owls.

Sheffield emphasized collecting a century's worth of data is invaluable to bird conservation efforts. Birds, he added, are often a strong indicator of the overall health of ecosystems and are easily found and measured the world over.

One of the trends the bird count tracks is what Sheffield called "irruptive species," those forced to move south because food supplies in their local ecosystems run low.

"We get these birds showing up, like snowy owls, evening grosbeaks, purple finches, red-breasted nuthatches," Sheffield observed. "You could go several years and you won't find any of them. All of a sudden, one year, you have many of those species. That tells you some information about their habitat conditions."

The bird count begins Dec. 14 and goes through Jan. 5. The count is conducted by thousands of volunteers in more than 20 countries in the Western Hemisphere.
