“…Our calculation method is an alternative approach, fits between these and, as demonstrated in Celi et al ( 2018 ), the values are sufficiently homogeneous with those determined by other methods.…”

“…The calculation method, already described in Celi et al ( 2018 ), is possible because oil companies declare a certain amount of CO 2 emissions for their oil and gas production. If we imagine "burning" all the oil produced, we get a certain amount of CO 2 , which was used as the numerator of the EROI index.…”

“…The reality of world oil companies, as already seen in Celi et al ( 2018 ), is very complex: there are private multinationals that work all over the world, not knowing state borders; there are state-owned companies that make up the GDP of an entire nation and, in between, there are a thousand other companies that extract but also refines petroleum products, while others do practically only refining services or other petroleum by-products. It is practically impossible to provide homogeneity criteria and therefore the method basically consisted in treating the companies themselves as black boxes and basing the calculations only on what they themselves declare in their reports.…”

“…Le TRE, taux de retour énergétique 13 du pétrole -qui est de très loin la principale source d'énergie utilisée dans le Monde-est passé de 100 barils extraits pour 1 baril (consacré à extraire le pétrole) en 1905, à 14 pour 1 en 2016 (Celi et al, 2018) 2014), la chute en cours des rendements énergétiques accroît le besoin de force de travail dans les secteurs qui fournissent de l'énergie, dont l'agriculture en priorité et la forêt. La proportion de paysans dans une population est inversement proportionnelle à la quantité d'énergie dont dispose chaque habitant (Jancovici, 2018).…”

Évaluer les innovations territoriales : performances, impacts et compatibilité

Comment designer ou contre-designer des formes d’innovations qui seraient de « véritables innovations territoriales » ? L’évaluation ex-ante est la clé pour réaliser un design ou un (contre)-design des innovations territoriales. Comment réaliser cette évaluation ? Faut-il enregistrer les performances des territoires ? Faut-il plutôt évaluer les impacts des changements sur les territoires ? Mais par rapport à quelle situation de référence ? Nous proposons les règles suivantes. Quand le changement introduit par l’innovation territoriale est vu comme marginal et situé dans un univers stable, l’évaluation par les performances est suffisante. Dans un univers en proie aux bouleversements, l’évaluation adéquate serait celle des impacts. Quand le changement n’est plus marginal mais fondamental, il devient pertinent d’évaluer la compatibilité de l’innovation à l’aune d’un scénario de référence. Nous illustrons ces trois cas par des exemples de terrain.

“…A new methodology for estimating EROI (Capellán-Pérez et al, 2019) and standard (De Castro and Capellán-Pérez, 2020) were developed. It is not certain that EROI will be the main decisive factor in the future (Hall, 2017), at the same time a new approach to calculating "corporate" EROI is under review (Celi et al, 2018).…”

An energy method for computing the use of fossil fuel energy

An energy method for computing the use of fossil fuel energy has been considered in the article. On the world market, the fuel price depends on supply and demand and involves no energy costs for fuel production. An energy analysis of economic activity was suggested by Charles Hall, an American scientist, who introduced a notion of Energy Returned on Energy Invested, as a ratio between returned and invested energy, into scientific discourse. No account has been taken of invested energy depreciation in this method. All losses are fully incorporated, when the ratio between beneficially used energy in all process flow chains from fuel deposit exploration to energy utilisation, and the considered amount of natural fuel primary energy is taken as the coefficient of beneficial primary energy use (CBPEU). When CBPEU is determined, allowance is made for all potential energy losses; the depreciation degree of energy, contained in the fuel, from its deposit to a consumer, is defined. When energy of renewable sources is utilised, a coefficient of renewable sources energy conversion, defined as the ratio between energy delivered by a power unit throughout the entire operation period, and invested energy taking into account CBPEU over the same period, will represent an objective criterion of power unit efficiency.
