"When a renewable energy producer requires capital to finance the initial cost of a renewable energy project, he may sell a portion of the energy to be produced in the future, on the WePower platform. The buyer/investor acquires this energy in a form of internal energy tokens. Each energy token acts as a smart contract indicating: 1) type of energy, 2) when the energy will be produced and delivered; 3) price tag. This smart contract represents a standard power purchase agreement between the renewable energy producer and energy buyer." -WePower Whitepaper
