2. Objectives The objectives of the present article are to first find out models for the energy consumption in the Hotels and second integrate renewable energy in order to arrive a real zero CO2 emissions. The information derived from the energy consumption curves of an area and the temporally consumption of the larger energy consumption sectors of the same area can provide us with a first approach to understand the problems and the possible technical solutions. An in depth analysis of a significant number of energy audits of different industries and buildings can provide us with the necessary information needed for an extrapolation of the energy demand. Furthermore, this will shed light for new ways for energy saving and integration of RES. For tourist areas, the biggest energy consumer is the tertiary building sector, and especially hotels. However, they usually have a centralized energy production which makes this analysis easier. Energy audits can help hotel companies find out energy management problems and improve energy efficiency, as well as indicating to the government the adequate energy policies to apply . 3. Case study. Balearic Islands The tourist industry is amongst the most dynamic areas within the services sector, and this is especially the case in Southern Europe (France, Greece, Italy, Spain and Portugal) [9]. The Balearic Islands have historically been one of the primary tourist destinations; there are about half a million beds available, and it is the first destination for Spain. Many successful hotel companies that have emerged during the last few years are now exporting their experience to other expanding destinations. However, one problem of the Balearic Islands energy model is that it is based on imported fossil fuels [2], only the 3% of the energy is from RES. The Balearic’s Islands over the last 7 years, there has been a decrease in the electrical energy consumption a 0,1%, with a 69% of increase of the Transport consumption with the Electrical Vehicle and Electrical Train. The global contribution of buildings towards energy consumption, residential has steadily increased, reaching figures between 4% ( from 1999 to 2009 was a 50%) and the Tertiary sector has decreased 1% where the hotels are included.
