Biomass, geothermal energy, marine energies, wind and solar energies (thermal, thermodynamic and above all photovoltaic) are leaping in the global energy balance because they are deemed to be the most in line with environmental protection. Where is their technological evolution? How competitive are they? By what means, technical and organizational, can we overcome the intermittent nature of some of them?
The conversion of solar radiation into calorific, electrical or chemical energy for our purposes is what is known as solar energy. Over time, this energy has become one of the major sources of renewable energy alongside biomass, hydraulic energy and wind energy. The use of solar energy is still quite

The notions of energy communities are very disparate. There are communities that originate from local initiatives and physically occupy a small piece of territory, neighbourhood, village, or campus. This is the type of community referred to below. But there are also other communities of the virtual type, with geographically dispersed

The ecological transition that is now being imposed on all societies, especially industrialized ones, requires an increasing use of renewable energy sources. Among them, alongside new techniques for producing electricity, biomass – historically used since the beginning of humanity – occupies a major place. But what is biomass? Originating mainly

Dong is not a Chinese company. It is the acronym for Danish Oil and Gas Company, created in 1972 for managing oil and gas resources from the North Sea Danish sector, and for producing and distributing electricity as a utility owned by the Danish Government. Incidentally, they developed and constructed

1. The devastating effects of household air pollution Indeed: “In developing countries, especially in rural areas, 2.5 billion people rely on biomass, such as firewood, charcoal, agricultural waste and animal dung, to meet their energy needs for cooking. In many countries, these resources account for over 90% of household energy

To understand the place photovoltaic solar energy has made for itself in electricity mixes, it is essential to know the resource and principles of converting solar radiation into heat or electricity. (Read: Énergie solaire : les bases théoriques pour la comprendre), but it is also necessary to discover its origin and
