bettervest is a crowd-investing platform that enables people to jointly invest individual sums of money – from as little as 50€ onward – in renewable energy, energy, and resource efficiency projects initiated by established enterprises, NGOs, and local municipalities. In return, investors benefit financially from the resulting cost and energy savings. The bettervest platform has thus opened up the energy efficiency market to private investors. With these targeted investments ecologically and economically viable energy efficiency measures are able to be implemented, leading to cost, energy, and CO2 reductions.
