Parducci Wine Cellars has announced plans to convert to 100% solar and wind power.

The family-owned California-based company, which was the first carbon neutral winery in the US, has transferred all of its energy needs to non-polluting, renewable sources by supplementing its on-site solar power with Green-E certified wind energy.

Parducci partner Tom Thornhill said: "Parducci is continuously striving to be America's greenest winery. This is an active and evolving process that never ends. It is a journey not a destination."

"In addition to buying grapes from local family farmers, Parducci uses sustainable farming practices including bio-diesel tractors in the vineyards and 100% green power as well as earth friendly packaging at the winery," the company added.
