energy [2], there is a future project to increase the cable for increase the power, but it’s not approved yet. Balearic Island’s with an installed power of 2490 MW and 80 MWp of PV installed, 20 MWp of Waste power plant, 3 MWp of wind power and peak consumption of 1205 MW [2]. The main generation system is composed of two thermal power plants responsible for, respectively, 72% and the 12% of the demand on each of the two island subdivisions, and a combined cycle central that started to use natural gas five years ago, in order to reduce the CO2 emissions and increase the efficiency. The rest is generated in 4 small distributed generation plants. The principal thermal power plant, with a nominal power of 510 MW, constitutes the basis of the system; it’s still working with coal, the most contaminant fossil fuel. The other Power Plants assume the peaks of demand in the islands. The described production model produces a high amount of CO2 emissions, because it is based on coal turbines. The use of coal as fuel also has an important effect, in the production of acid rain. Actually the PV produces some hours only the 10%, with annual production of 2%. The government’s Energy Planning Project intends to reduce global energy consumption by 3%, and increase by 35% the use of Renewable Energy Sources (RES) at 2030 and to 100% in 2050. In 2050 will be needed 20 times more of PV, that will be necessary to storage or make intelligent most of the buildings. Figure 3. Electric consumption-production and Hotels estimation consumption , August 2016 [10]. 3.3. Intelligent Electric Consumption There are a lot of studies and software that have calculated the energy savings and feasibility of the incorporation of systems exploiting RES and the adoption of techniques intelligent energy use for different tourist areas and countries. The main solutions are the improvement of the efficiency process of the system technology and the management of these systems.
