SUSTAINABILITY LEADERSHIP PILLAR: ENERGY SAVINGS & EFFICIENCY

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:

  • Go electric – tractors that is. The new electric Monarch Tractors help growers save fuel and costs in the vineyard.
  • Night-time air for natural cooling in the cellar
  • Upgrade to LED lighting
  • Install motion sensors to automatically control lighting
  • Use skylights and other daylighting
  • Install VFDs on motors and compressors to phase operation based on demand
  • Reduce hot water temperature to 120-140 when higher temps are not needed for cleaning
  • Consistent monitoring & maintenance of equipment
  • Keeping thermostats locked at efficient settings (68 in winter, 76-78 in summer)
  • Improve water efficiency – it takes significant energy to heat, treat and transport water
