  Rooftop Solar in Memphis

 

                                                          

WMC-TV in Memphis recently reported on a new project coming to the city.

 

Allan Daisley and Kirk Williamson from the Memphis Bio Works Foundation are proposing a plan to help make the City of Memphis more energy efficient.

 

Their goal is to place solar panels on the rooftops of 30 city-owned facilities.

 

A private investor is willing to finance the cost and the city will receive a small amount of revenue for leasing the rooftops. The energy will be sold to the Tennessee Valley Authority.

 

The project is part of the "Green and Clean" initiatives to help the environment and to improve quality of life.

 

"Memphis is one of the best places in the state to do solar because we have so much sunlight every year," said Daisley. "With 30 installations we can power the equivalent of 200 average U.S. homes."

 

He is proposing adding more than 6,000 panels to city-owned buildings.

Here is how it would work: The city would lease 30 rooftops at $250 dollars a year. Then crews would install panels on the rooftops and begin generating energy to sell back to the TVA.

Private investors are set to pay for the plan.

 

Daisley says it only helps Memphis.

 

"We're doing this to stimulate economic activity while at the same time changing the face of Memphis and making a better places to live," he said.

 

Not to mention, it would take the load off the grid during extreme weather conditions.

 

"This absolutely helps with the consumption of power both on cold days and on warm days when the air condition is running all the time," said Daisley.

 

Farm in a Box

                 
The Times-Free Press recently reported on an environmentally friendly way to feed your family from a self contained unit.
  

A Rossville, Ga., aquaponics company has launched a new product that will allow individuals to grow fish and vegetables to feed a family of four - all from a four by six foot farm-in-a-box that plugs into the wall.

HATPonics debuted its residential aquaponics system at Green Spaces in Chattanooga to a group of about 40 interested people and walked away with seven orders, CEO Ryan Cox said.

 

The system includes both a fish tank and a vegetable garden. The two parts are set up in a balanced, self-sustaining ecosystem -- the fish fertilize the plants, while the plants filter the fish waste out of the water. A family could grow cucumbers, tomatoes, peppers and lettuce in the top half of the system while raising tilapia, trout or catfish on the bottom half.

 

A fully-functional system will produce at least four salads a day and about a fish-a-week, Cox said. The 200-gallon fish tank can fit between 30 and 50 fish, which take about nine months to mature from fingernail-sized to 1 pound.

 

"This is so people can start taking control of their own food supply," he said. "A family wouldn't eat purely off of this, but it would supplement their food and eliminate the need to purchase fresh produce daily from a grocery store."

 

Chattanooga resident Candy Lusk thinks the the system -- which can run either on solar or electric power -- sounds like a good fit for her lifestyle.

 

"Grocery stores are getting expensive, and I prefer organic," she said. "I have a garden, but this uses less water and seems to be lower maintenance, and you don't have animals or pests eating the plants."

 

HATponics' residential system can be set up either inside or outside, Cox said. Each farm requires about the same amount of sunlight as a typical backyard garden, although artificial lights allow the systems to grow almost anywhere -- including basements and garages.

The new products retail for between $650 for a basic model and $2,000 for a model with all the bells and whistles, Cox said. Fish food may cost another $20 a year, he added. The farms are a micro-version of HATponics' $140,000 aquaponics farms, which hold about 3,100 fish and can feed as many as 500 people a week.

 

The company, which launched in 2013, hopes to feed 20 million people by 2020, Cox said. For every top-of-the-line residential system he sells, he'll donate one basic model to a family in an impoverished area.

 

"Whether we're helping in Nicaragua or right here at home in Chattanooga, our goal is to make sure people have access to food," Cox said. "That's the coolest part of what we do."

Aquaponics -- the practice of growing fish and vegetables together -- is gaining popularity across the nation, but is still an emerging and fairly complicated process, said Joel Houser, executive director at Crabtree Farms in Chattanooga.

 

"It's ambitious, and it's got to be a delicate system, because there are so many animals and plants in such a close proximity," he said. "It's kind of like a hot rod. If you can get it to work and run good, then you'll have food out of it."

 

But, he added, aquaponics can be tough. Because it is an interconnected system, one problem can quickly ruin a whole crop. You've got to worry about the different nutrients that fish and plants require, he said, and carefully regulate variables like temperature.

 

"With a system like that, if the power fails, then you lose the fish," he said. "We're always a little more careful to try things when they involve animals as well. We want to be very careful about that."

 

But he hopes the residential systems will work and gain popularity.

 

"Because if they do, there will be a lot of food produced on a very small acreage," he said. "I sincerely hope they can do it."

 

As demand grows, Cox hopes to keep selling the residential products directly to consumers, and is developing distribution channels.

 

HATponics employs 10 people and manufactures the farms out of a Rossville facility.

 

  Greenest Superbowl Ever?

 

 

Staff at Sustainable Business news recently wrote about the NFL's efforts to become greener in it's efforts. 

 

U.S. sport teams and stadiums are competing over which is the greenest, with energy efficiency, renewable energy, recycling and composting becoming common in the professional sports world.  

Once again, the National Football League says it will serve up the greenest Super Bowl ever at MetLife Stadium in Rutherford, N.J. 

 

Although it only got a score of 2 out of 4 from the Green Restaurant Association, MetLife is the first stadium in the world to meet its rigorous standards. With over 200 restaurants onsite serving up to 100,000 people in a day, it's also the largest food service operation to receive this certification.

 

Notably, all the waste oil generated from food production will be converted into biodiesel fuel and all food scraps will be composted. Leftover food will be donated and materials such as plastic, glass, aluminum and paper will be recycled. No styrofoam containers will be used at the game. Energy Star equipment will be used to make all the food.

 

"From the very beginning, our owners committed to build and operate one of the most environmentally responsible stadiums in the National Football League," says Brad Mayne, MetLife Stadium president and CEO. "We thank our partners at Delaware North for their efforts in helping MetLife Stadium become the first Certified Green Restaurant stadium in the world."

 

Met-Life Stadium incorporates some solar, recycled materials in construction and in its seats, in addition to a heavy emphasis on recycling and composting during events. Other stadium innovations include: net-zero energy for the San Francisco 49ers and Philadelphia Eagles; the San Francisco Giants' edible garden; solar power at the Washington Redskins' FedEx Field; and a LEED-Platinum ranking for a university stadium in Texas.

 

Of the 126 professional sports teams in the five major North American leagues, 38 have shifted at least partially to renewable energy and have energy efficiency programs, reports the Natural Resources Defense Council (NRDC) and the Green Sports Alliance. They are also taking the opportunity to educate millions of people about these practices - 61 percent of Americans identify themselves as sports fans, compared to just 13 percent who follow science.
