The deregulation of the electric energy market has changed the power plants from cost centers into profit centers. Operating incomes are due now not only to the quantity of energy produced but also to the best moment of its production and to a fast response to electricity demand. Operation costs are due not only to the fuel cost but also to the...

The late EU Standards promote more and more the renewable energy sources utilization for the electricity and heat production. In this framework biofuels assume a basic role and, among them, biodiesel is a good alternative to fossil fuels. The paper considers the frying oils and facts that derive, by a transesterification process, from fast-food...
