    other renewables

    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?

    21 March 2022
    Among the energy solutions aiming at both mitigation and adaptation to climate change, geothermal energy assisted by geothermal heat pumps has an important role to play, especially in the field of space heating and cooling for new buildings, but also in thermal renovation strategies as climate change is expected to

    3 February 2022
    The development of renewable energy is seen as an improvement for the global energy system due to limited fossil fuel resources, as well as to reduce the environmental problems resulting from the massive use of fossil fuels. In this context, the use of biomass and waste has become a sustainable

    7 December 2021
    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

    8 June 2021
    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

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
