Green electricity – because together we can make a difference

Green electricity is clean

For us, green electricity means climate-friendly and environmentally friendly energy from hydro, wind and solar power.

Green electricity is a necessity

By producing green electricity, we're playing a key role in replacing nuclear power. That is why we promote the expansion of green power plants.

Green electricity is sustainable

Water, wind and sunlight will always be available as energy sources in the future. We can therefore be secure in the knowledge that reliable production of green electricity can continue.
