Renewable and Sustainable Energy: Solar Energy and Electrical System Design

In some parts of the world, our dependence on fossil fuels has lasted much longer than it should have. The transformation and sustainability of the energy sector can therefore be seen as one of the most important challenges we face today. The International Energy Agency (IEA) has published that the final consumption of electricity increases by 25% from 2020 to 2030 according to the Net Zero Emissions (NZE), of which the building sector accounts for nearly 32% of electrical energy. Thus, the orientation towards new energy sources remains the only way to meet our daily needs and to keep a sustainable autonomy. This article proposes a solution to the problem of ensuring a sustainable power supply for a building, and to do this it is necessary to rely on a methodology that consists first of making a collection of data for the various electrical equipment of the building, [1] then taking advantage of them for the calculation of energy needs. Finally, and after this assessment the sizing of electrical devices for sustainability and energy optimization.
