Making wine is actually quite energy intensive. It takes a lot of refrigeration to cool, ferment, and age wines. A lot of hot water to sanitize tanks, barrels, and bottling lines. Napa Green baselines and tracks the energy use of all of our members. Energy efficiency is one of the quickest ways to cut the bottom line.
We’ve seen a winery that makes 25,000 cases of wine spending $2/case on electricity, and another winery of exactly the same size spending $6/case. That’s a difference of $100,000 a year in electricity costs to make the same amount of wine!
Here are some examples of energy efficiency opportunities in vineyards & wineries:
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.
ZD Wines, a family-owned winery operated by the 2nd and 3rd generations of the deLeuze family, is celebrating 50 years in the Napa Valley. They are a perfect case study of how embracing sustainability can support production of great tasting, world-class wines.
Energy efficiency is a core priority for Napa Green Wineries, both for conservation and cost-savings. Maximizing efficiency is especially important when considering the installation of solar renewable energy. As we say, “We don’t want to solarize inefficiencies.” The more efficient the operation, the smaller the scale and footprint of the solar array, reducing the price tag.
