Fixed Capital Formation

There is growing interest for the use of renewable energy and carbon dioxide emission in Nigeria, and the world over.Despite the volume of consumption, and the enabling oil and gas laws to protect the environment and improve the well-being of citizens over the years, the gross fixed capital formation have not received a remarkable growth in Nigeria which motivated for this study. The gross fixed capital formation was the dependent variable against energy consumption, and carbon dioxide emission that represented the explanatory variables were sourced from the World Bank and the Central Bank of Nigeria Statistical Bulletin between 1985-2014. The study adopted the Augmented Dickey-Fuller and the Autoregressive Distributive Lag model for the analysis. The data were integrated at levels and first order differenced. The Johansen cointegration test indicated co-integrating equations in long run. Furthermore, the error correction found energy consumption to be positive, while carbon dioxide emission had a negative but insignificant impact on the Nigerian fixed capital formation. The study recommended the ministry of environment to enforce the existing oil and gas laws, and advocate for the use of modern energy in rural areas of Nigeria.

Concrete is the most widely used building material all around the world which has been undergoing many changes aligned with technological advancement. The most recent available type of concrete is high performance concrete which is produced employing different admixtures both chemical and mineral to enhance mechanical and durability qualities. As sustainability emerged as an indispensable factor in concrete industry, many researchers targeted micro sized mineral admixtures such as silica fume, fly ash, rice husk ash, slag and so on in order to replace Portland cement which is known to be responsible for almost 7% of carbon dioxide emission into atmosphere.Recently, technology has made it easy for scientist to study nanoscale admixtures and their effect on structure of concrete. This paper reviews nanomaterials in cement composites and how they can improve different properties of concrete.

Energy Efficiency Design Index

The round-the-world transition of m/v Katherine ship is considered. The aim of this work is to minimize the Energy Efficiency Operational Indicator (EEOI) of the vessel, and, accordingly, to minimize the ship's fuel consumption and carbon dioxide emission depending on the parameters of sea transition: Vs, mass of transported cargo, and the distance of the passage. For specifically selected ship power plant (SPP), the parametric dependence of Vs and fuel consumption on the share of used power is determined by calculation method. The Energy Efficiency Design Index (EEDI) is determined by the model given in Resolution MEPC.212(63). The EEOI is determined depending on the ship fuel consumption, the carbon concentration in the ship’s fuel with the main parameters accepted for transition Vs, transported cargo mass , the sea passage distance . Calculation studies are conducted in a wide range of sea transition parameters – transition distance within 200 to 2,800 nm, the Vs from 0.01 to 24.0 knots, cargo mass ranging within 4,000 to 70,000 tons.

ABSTRACTThere are lessons from recent history of technology introductions which should not be forgotten when considering alternative energy technologies for carbon dioxide emission reductions.The growth of the ecological footprint of a human population about to increase from 7B now to 9B in 2050 raises serious concerns about how to live both more efficiently and with less permanent impacts on the finite world. One present focus is the future of our climate, where the level of concern has prompted actions across the world in mitigation of the emissions of CO2. An examination of successful and failed introductions of technology over the last 200 years generates several lessons that should be kept in mind as we proceed to 80% decarbonize the world economy by 2050. I will argue that all the actions taken together until now to reduce our emissions of carbon dioxide will not achieve a serious reduction, and in some cases, they will actually make matters worse. In practice, the scale and the different specific engineering challenges of the decarbonization project are without precedent in human history. This means that any new technology introductions need to be able to meet the huge implied capabilities. An altogether more sophisticated public debate is urgently needed on appropriate actions that (i) considers the full range of threats to humanity, and (ii) weighs more carefully both the upsides and downsides of taking any action, and of not taking that action.
