Honig Vineyard & Winery has spent the past ten years investing in energy conservation and renewable energy, and it all started with a PG&E energy audit. As a result of the initial audit, which included an assessment of their existing energy use and recommendations for upgrades, Michael Honig and his team changed out all of the old lighting for the highest efficiency lighting with a no-brainer payback period. They then optimized their processing and refrigeration equipment for maximum efficiency, making sure that future energy investments weren’t just subsidizing inefficiencies.

The next step? Evaluating their property for solar. Although the idea of “marginal” farmland in Rutherford is hard to imagine, the family had just that – a small plot of land that wasn’t great for growing grapes, but was perfect for turning sunlight into energy. In 2006, the winery flipped the switch on 819 solar panels, generating 147 kilowatts, covering roughly 1/3 of an acre of land. At the time PG&E covered one-third of the cost, state incentives covered another third and Honig covered a third with a ten year low interest loan.

Built in 2006, Honig’s first solar array generates 147 kilowatts of power.

In the nine years since their initial solar investment, Honig has experienced significant growth, roughly doubling production and building new offices and operating facilities. Looking to expand their installation, the roofs on their new facilities are providing the perfect opportunity. Fortunately, the cost of solar has gone down, while the efficiency of photovoltaic cells has gone up. Starting this month Honig is beginning installation of a new system that will more than double solar energy generation, with 180 kW across six roofs. They expect to have this expanded system paid off in less than six years.

“When it comes to sustainability you can’t be a luddite and invest in one project and say you’re  done - it’s all about continual improvement,” said Michael Honig, the winery’s president. “That’s what Napa Green is all about. We could have just said we installed solar and be done, but we’re continuing to invest in new projects.

“Wineries are typically family-owned, generational businesses. You’re not going to stop using power, and power is only going to get more and more expensive. It makes so much sense to invest in solar. It has a five or six year payoff and then you’re saving money.”


When the winery does draw energy, it receives power from 100% renewable sources through Marin Clean Energy’s “Deep Green” program.

Generating solar power continues to be just part of the energy equation at Honig Vineyard & Winery. Michael notes that small changes like running pumps at night and putting in light sensors throughout the facility have made a difference in overall energy consumption. “Some of this is basic - once you focus on turning off unneeded lights you realize how often things get left on. Little changes can make a big impact. Every effort counts,” Honig concluded. Like many vintners, Honig made the switch to MCE Clean Energy in early 2015. The default option delivers power to customers largely from renewable sources. Honig went one step further, electing the Deep Green option for their facility, ensuring that any energy they do draw from the power grid is 100% renewable.

Michael Honig believes a sustainable company culture has to start from the top. “Kristin Belair, our winemaker, has always had this mentality of leaving a low footprint. So we make investments and lead by example. We show the employees we don’t just talk about these things,” Honig said. Errands for the business demonstrate this commitment. Honig noticed that employees were running errands in their private vehicles throughout the week. The solution? Purchasing a 100% electric Nissan Leaf and installing an electric vehicle charging station at the winery. The Leaf gets 126 mpg and can go up to 90 miles on one charge - perfect for local use. “The Leaf and the charging station get a ton of use. A grower showed up the other day just to plug in,” Honig said.

“Living and working on this property I realize I am the caretaker for this generation. I want to pass it on to the 4th generation, and hope it continues to the 5th and 6th generation. That means both the business and the land need to be healthy and vibrant. We’re creating healthier soils, healthier employee and healthier wines.”

Little changes add up. To improve energy efficiency at your winery Michael Honig recommends:

  1. Get a free PG&E energy audit. They’ll identify opportunities to improve efficiency, make upgrades and clearly lay out your payback period. They also have rebates and financing options.

  2. Revisit Solar. Even though solar has become standard technology, many of people haven’t jumped in. If you haven’t pursued solar in the past due to costs, it’s time to revisit. Costs have dropped substantially. For many vintners, it makes sense.

  3. Go Deep Green with MCE Clean Energy. MCE became active in Napa County in February 2015 and everyone signed up with PG&E in unincorporated Napa County is automatically enrolled in their Light Green 50% renewable energy program. You can sign up to get 100% renewable energy at prices that are very competitive with traditional energy - and often even cheaper.

  4. Think about energy in a broader context. For example, hauling waste uses a lot of energy. Kristin Belair recently requested a waste audit and we’re going to ask our staff if we can reduce our waste by 20% in the next year. It probably won’t require a big plan - we just need to talk to our operations staff and make sure they’re sorting and know what’s recyclable. This won’t just reduce waste, it will also save energy.

  5. Keep Improving. Sustainability is not a one-off investment. There are always new ways, even small ways, you can lead by example and make sustainability a part of your business culture.
