Abstract

This article investigates the Product Electricity, the product being sold at our power markets and distributed via our electric grids. The paper aims to enhance the understanding of the physics behind the Product Electricity. The traditional (physical) perspective of the purchase of power might have been compromised already in the early 1900’s. This investigation aims to clarify what electric power really is, how it is traded, and if the different offers of so called ‘Green Power’ are valid.

A deregulated power market is ruled by the laws of the free-market, i.e. Supply and Demand. It is not ruled by the laws of Ohm and Kirchhoff. To purchase the Product Electricity is to place an order of consumption beforehand, not specified in volume, space or time. The economical transaction; purchasing electric power, is strictly non-physical.

Today, an active choice of not buying fossil power is advertised on the power markets. Customers who do not want to get electricity generated from fossil fuels are offered to stop buying it. This article tries to answer the question if that offer is valid.
