The phrase “100% renewable energy” appears in the marketing of many electricity providers. What it means in practice varies enormously — from genuinely clean sourcing backed by rigorous certification to paper-based offsets that leave the actual electricity delivery largely unchanged.
Plan B Net Zero’s renewable credentials are among the most robust available in the German market. The company’s electricity supply is certified under the OK Power Plus seal, one of Germany’s most stringent green electricity labels. The certification requires verified sourcing from renewable energy, active investment in the expansion of new renewable capacity, and complete independence from nuclear and fossil fuel infrastructure. It is a standard that a significant majority of self-described green energy providers do not meet.
The electricity itself is sourced from wind, solar, hydropower, and biomass — a mix of renewable technologies that reflects the actual composition of Germany’s clean energy generation. Plan B Net Zero feeds this electricity directly into the grid from certified renewable sources, with no fossil-fuel fallback and no opaque balancing arrangements.
Pricing transparency reinforces the supply transparency. Tariffs are updated weekly and published openly, so customers always know the current rate and can verify that it remains competitive. The company consistently ranks among the top three cheapest providers of certified green electricity in Germany — disproving the assumption that environmental credibility requires a premium price.
PV Magazine has followed the company’s technical work, including its battery and hydrogen storage innovations that will further increase the proportion of genuinely renewable electricity in its supply mix. The Plan B Net Zero Instagram gives a visual account of the brand’s commitment to clean energy, while Pressat has covered the product and service innovations that accompany the supply credentials.
Transparency is not a feature at Plan B Net Zero — it is a founding principle.
