All fuels or all energy sources must in principle compete on their own merits. Environmental costs are internalised in the pricing system. A national energy and environmental policy cannot be pursued without taking regard to the limits imposed by conditions in the international market, and by European integration in particular. Nevertheless, as will be described later in this paper, taxes and charges play a central role in the financial calculations of different energy supply options. A clear separation has been made between production and trade in electricity, on the one hand, and the grid and local network operations on the other.
Network operators are so-called natural monopolies and are therefore still regulated.
Their task is to distribute electricity at a reasonable cost and on non- discriminatory basis, regardless of who is the producer, trader or endcustomer. Trade in electricity is not the object of special legislation. Power companies that are owners of what is regarded as green energy sources are proudly advertising and offering their green electricity production. Whatever the case, a competitive market allows the customer to bring great influence to bear in determining to what extent electricity will be generated from renewables, e.g. bioenergy fuels, in the future. To a great extent.
