Published on Terra Nullius Blog Authoritarian Capitalism: Is the world transitioning to a post-democratic market system? Capitalism changes with its organic crises and the way the state manages these crises. From the Long Depression — arose organized capitalism set in a world of inter-imperialist rivalries, from the Great Depression — The question is: is this crisis over? And, if so, has a new capitalism already arisen out of the crisis of global financial market capitalism? Biological Hydrogen Methanation. Power-to-gas strategy consists in the utilization of excess electricity produced by renewable energy sources, when demand does not match supply rate, to convert water into H2 and O2 through electrolysis and subsequent chemical or Power-to-gas strategy consists in the utilization of excess electricity produced by renewable energy sources, when demand does not match supply rate, to convert water into H2 and O2 through electrolysis and subsequent chemical or biological methanation of H2 and CO2.
The biological method can be performed in-situ, whereby H2 is supplied directly to the anaerobic digester so that archaea can consume H2 and CO2, hence additional units for upgrading may be avoided.

H2 transfer to the liquid phase has been identified as the limiting step for the conversion and several reactor configurations have been applied to increase specific mass transfer coefficient. In this project, operating pressure is increased to enlarge gases solubility, thus reducing CO2 content in biogas and facilitating H2 transfer to the liquid phase according to Henry's Law. This paper aims at examining the relationship between energy consumption deriving from renewable energy sources, and countries' economic growth expressed as GDP per capita concerning 25 European countries.
The used dataset involves The used dataset involves European countries' data for the period from to The statistical analysis is based on descriptive statistics, cluster analysis, and autoregressive distributed lag ARDL , and reveals that all variables are related; this suggests a correlation between the dependent variable of GDP and the independents of renewable energy sources RES and Non-RES energy consumption, gross fixed capital formation, and labor force in the long-run.
Furthermore, the results show that there is a higher correlation between RES' consumption and the economic growth of countries of higher GDP than with those of lower GDP.
The obtained results are consistent with other papers reviewed in this study. End of fossil fuel economy: weathering the storm of transition to post-fossil society in Nigeria. Nigerian economy built on petroleum faces a carbon catch Despite this, there is Despite this, there is no concrete fossil-fuel exit strategy FES to surmount the gathering storm when the petroleum bubble burst. Using quantitative data, the study finds that power generation would be reliant on fossil fuels due to its cost-effectiveness in the advent of FES imposed availability.
Hence holistic smart energy system; large-scale biomass production targeted at feedstock exports, improvements in agriculture, massive renewable energy generation in wind, solar, hydropower and increased off-grid power generation would reinvigorate the economy in the post-carbon era. The study concludes that large-scale bamboo cultivation can provide energy and generate additional income with the private sector providing new investments in other renewables capable of leveraging enormous natural resources to generate revenue.
Keywords: low-carbon growth; clean energy transition; oil age; bamboo; fossil-fuel exit; biomass economy; sustainable development; green economy; post-fossil society; renewable energy; natural resources; post-petroleum society; Nigeria. Reference to this paper should be made as follows: Okoh, A.
Presently there are numerous environmental issues and challenges of the nation that need to be addressed at all levels with the coorperation of various parties to protect the earth life support systems.

This paper discusses how problems of eco-opportunism in metals markets escalate due to market failures because of increasing scarcity of precious metals. Establishing the right sourcing strategy for recycled material therefore is crucial Establishing the right sourcing strategy for recycled material therefore is crucial for supply chains. Consequently, the need for traceable supply encourages companies to integrate closed loop recycling of their products. Furthermore, scarcity of valuable metals along with consumer preferences for sustainable products lead to specific investments in product design and robot technology that disassemble end-of-life products.
Together, these factors provide an integrated system that reduces transaction costs and increase recycling efficiency. Therefore, specific assets designed to facilitate reuse of scarce metals like the Apple robot Daisy, is a key corporate strategy to secure sustainable performance.
Specific investments in disassembling technology like robots in the smartphone industry, should, according to transaction cost theory, be organized as a vertically integrated circular economy. The integrated closed loop model presented here, control eco-opportunism and the unsustainable character of grey markets for recycled material in electronics.
