I was interested to change to a power to gas subscription from greenpeace energy in which they offer to invest into power to gas (wind and solar energy is electrolytically transformed into methane that can be transported with the existing fossile gas network) yet to be built. I disliked that right now there is only a minor proportion of power to gas included in their regular fossil gas supply and that there are too few investors. I argued that they should offer a high priced but consequent product which they didn't seem to understand. Hence this model :-)
