“…The projections of final energy demand forecast the largest increase in the BAU scenario at 206,681.22 KBOE and the lowest growth for SCENARIO2 at 112,286.78 KBOE. A close relationship could be observed between the final energy supply and the final energy demand, which could be mainly associated with a transition towards energy production from renewable energies [58,[85][86][87].…”

Climate change and global warming are related to the demand for energy, energy efficiency, and CO 2 emissions. In this research, in order to project the trends in final energy demand, energy intensity, and CO 2 emission production in Ecuador during a period between 2000 and 2030, a model has been developed based on the dynamics of the systems supported by Vensim simulation models. The energy matrix of Ecuador has changed in recent years, giving more importance to hydropower. It is conclusive that, if industrialized country policies or trends on the use of renewable energy and energy efficiency were applied, the production of CO 2 emissions by 2030 in Ecuador would reach 42,191.4 KTCO 2 , a value well below the 75,182.6 KTCO 2 that would be seen if the current conditions are maintained. In the same way, by 2030, energy intensity would be reduced to 54% compared to the beginning of the simulation period.Between 1750 and 2011, cumulative anthropogenic CO 2 emissions to the atmosphere were 2040 ± 310 GTCO 2 . About 40% of these emissions have remained in the atmosphere (880 ± 35 GTCO 2 ) [5]; the rest have been removed from the atmosphere and stored on land (in plants and soils) and in the ocean. People's life expectancy is threatened by climate change through the limitation of access to water, food, medical care, and land. Therefore, it is important to reduce the consumption of fossil fuels and increase the use of renewable energy in order to minimize CO 2 emissions [13].Sustainability of power systems with high renewable energy penetration rates is a topic of major interest, especially when considering the intermittency of renewable energy source (RES) production and the actual growing trend of energy consumption [6]. The transition from fossil fuels to RESs is an indispensable necessity if sustainable socio-economic systems are to be realized. RES variability now represents a major challenge when it comes to upgrading power systems. From a social and economic perspective, the RES share in meeting electricity demand has shown a steady growth [7]. The increasing renewable energy share in electricity generation as a result of several factors such as environmental constraints, technical and economic aspects, or social implications has led to a corresponding reduction in total CO 2 emissions [8].The energy return on investment (EROI) metric includes factors affecting the whole energy system that are not accounted for by the monetary costs of individual power plants (such as additional costs for the system related to distribution, intermittency of RES, etc.) [14][15][16][17][18][19][20]. The transition to new energy resources and to new energy conversion and storage devices will affect the fraction of energy reinvestment, which could have significant economic impacts [21][22][23][24][25][26]. Those RESs with a higher potential (i.e., wind, and solar) have been generally found to have a lower EROI standard (EROIst) than fossil fuels, especially when incorporating the energy costs of dealing with intermittency [9].Energy ...

“…Regarding the future potential impacts of climate change, several studies have assessed the impact of climate changes on renewable generation. In ref [ 29 ], the most relevant quantity projections of PV generation were reviewed. The conclusions are often focused on specific areas, because climate changes can lead to increased generation in some regions and decreases in others.…”

University campuses are normally constituted of large buildings responsible for high energy demand, and are also important as demonstration sites for new technologies and systems. This paper presents the results of achieving energy sustainability in a testbed composed of a set of four buildings that constitute the Telecommunications Engineering School of the Universidad Politécnica de Madrid. In the paper, after characterizing the consumption of university buildings for a complete year, different options to achieve more sustainable use of energy are presented, considering the integration of renewable generation sources, namely photovoltaic generation, and monitoring and controlling electricity demand. To ensure the implementation of the desired monitoring and control, an internet of things (IoT) platform based on wireless sensor network (WSN) infrastructure was designed and installed. Such a platform supports a smart system to control the heating, ventilation, and air conditioning (HVAC) and lighting systems in buildings. Furthermore, the paper presents the developed IoT-based platform, as well as the implemented services. As a result, the paper illustrates how providing old existing buildings with the appropriate technology can contribute to the objective of transforming such buildings into nearly zero-energy buildings (nZEB) at a low cost.

Most power plants produce electricity by converting a mechanical motion into alternating current (AC). Photovoltaic solar panels convert an electromagnetic flux of light into direct current (DC). In general, electric energy can be harvested from a flux in the environment or from a change of the environment itself. One can produce electricity from mechanical, chemical, thermal, electromagnetic (light), or another physical flux, or from a change of temperature, chemical composition, or a physical field: gravitational, magnetic, electric, mechanical stress and strain, etc. Flux examples are mechanical motions of air and water, surface waves and tides, heat fluxes due to a temperature gradient, solar light, and a chemical flux (such as humidity propagation in the atmospheric air or diffusion of salt in water due to a gradient of salinity at the mouth of a fresh-water river flowing into an ocean). Environmental changes are under-used in energy production, although people are exposed to daily and seasonal changes of the environment, which include changing air temperature, pressure, humidity, and composition, tidal changes of the gravitational field, and less periodic changes of the geo-magnetic and electric fields. Production of electricity without fuel from the environmental changes and fluxes requires a durable infrastructure for a costeffective utilization of the "semi-perpetual" energy resources.
