This paper aims to demonstrate in a comprehensive yet clearly arranged and short digest how we are able to end an unfair, dangerous, environmentally unfriendly, and increasingly expensive energy supply and usage towards a fair, clean, and lower cost energy situation for everyone in the future. The important role which Photovoltaics (PV) has to play is emphasized but also the necessary portfolio of other renewables, notably wind, together with the large scale introduction of electricity storage. With today’s existing power purchase agreements for PV, wind and also new nuclear power stations it is shown that already with current prices, renewable electricity is 5–10 times less expensive compared to new nuclear and clean fossil power stations. Especially the economic argument will quickly drive the development towards a 100% renewably powered world within this century and provide energy at lowest price for everyone, highest security of supply everywhere and helping best to solve the climate battle.
