Zellar has assessed all of the electricity suppliers products and have made decisions on those that are 100% renewable and will have zero emissions. These are what we call deep green. There are lots of supplier products that legally state they are green and zero emissions, but at Zellar we have excluded products from the ‘Deep Green’ category that we believe contain fossil fuels. This way customers get an independent assessment of the source of the fuel as being truly green when they buy a Deep Green product.
