“…In their research, they showed how emissions could be reduced in South Africa up to 12.3% considering a specific e-car, e-truck and e-bus penetration in the market. Bastida-Molina, Hurtado-Pérez and Peñalvo-López drew similar conclusions proving that emissions can be reduced by increasing the number of electric vehicles (EVs) and boosting the number of MW of renewable energy (RE) [4]. As they stated in their research, a 100% RE generation will be needed in order to reduce up to 74 million tons per year.…”

Energy consumption in the transport sector and buildings are of great concern. This research aims to quantify how eco-routing, eco-driving and eco-charging can increase the amount of energy available for vehicle-to-building. To do this, the working population was broken into social groups (freelancers, local workers and commuters) who reside in two cities with different climate zones (Alcalá de Henares-Spain and Jaén-Spain) since the way of using electric vehicles is different. An algorithm based on the Here® application program interface and neural networks was implemented to acquire data of the stochastic usage of EVs of each social group. Finally, an increase in the amount of energy available for vehicle-to-building was assessed thanks to the algorithm. The results per day were as follows. Owing to the algorithm proposed a reduction ranging from 0.6 kWh to 2.2 kWh was obtained depending on social groups. The proposed algorithm facilitated an increase in energy available for vehicle-to-building ranging from 13.2 kWh to 33.6 kWh depending on social groups. The results show that current charging policies are not compatible with all social groups and do not consider the renewable energy contribution to the total electricity demand.

“…Generating power via a hybrid system such as a turbine/solar (PAT-PV) and traditional diesel on fossil fuels has been shown to decrease environmental impacts by reducing the consumption of fossil energy and using the surplus energy in powering vehicles or power tools to achieve more sustainable agriculture [40]. Currently, and also related to transportation, there are electric vehicles that do not produce emissions when driving, but they do rely on a carbon-intensive electricity generation system, so a 100% renewable system would be necessary to reduce emissions by up to 74 million tons per year [41]. The introduction of urban electric buses over the next 10 years (2020 to 2030) would reduce emissions by up to 92.6% with respect to 2018 levels [42].…”

This paper analyzes the impact of the fall in household consumption after an economic crisis in Spain on greenhouse gas emissions. To this end, household consumption is differentiated by the age of the main provider by using a conversion matrix that relates consumption groups to activity sectors. A multisectoral model was used to quantify and compare the environmental impact caused by the consumption of each age group, indicating that the older the age of the main household provider, the smaller the reduction in GHG emissions associated with their consumption. The results facilitate an analysis of how the greenhouse gas emissions of the different sectors of the Spanish economy, associated with the population under study, varied before and after the 2008 crisis, and confirm that the sectors with the greatest reduction in emissions were, in this order, extractive industries, construction, manufacturing industry, wholesale and retail trade and transport and storage. This is relevant for decision making in the field of environmental policies in crises, akin to the one the world is currently experiencing.

“…The introduction of EVs is intended for a decarbonisation of the transport sector [5,34,35]. However, a recharge of these vehicles exclusively based on the grid could even lead to an increase of the emissions, depending on the carbon intensity (CI) generation mix of the grid [9,10,35].…”
