Renewable energy (RE) creates opportunities for sustainable, socioeconomic development of local communities as fossil fuel-based energy imports are substituted with local RE sources. Established methods such a...
An important avenue toward a proper ‘energy transition’ through regional and local projects is for government to collaborate with private sector organizations. In the energy sector, these latter organizations ...
The challenge of lack of access to electricity especially in the rural areas of Nigeria is further compounded by the lack of cogent electrification plans. A fairly reasonable electrification plan should be abl...
The heavy reliance of the global food chain on the use of fossil fuels and anticipated rise in global population threatens future global food security. Due to the complexity of the food and energy systems, the...
Mankind is highly dependent upon fossil fuels for its ever-increasing energy demands. The future supply is unreliable mainly due to the fact that it is a finite resource which is becoming more and more expensi...
In Germany, the energy system is undergoing reorganisation from a centralised system based on fossil fuels and nuclear power to a sustainable system based on decentralised production and consumption of energy,...
Energy crops are of considerable importance for biogas production, especially in Germany. The main energy crops for that purpose are corn silage, grass silage, whole crop grain silage and other non-legume crop...
For a precise description of the emission situation of the anaerobic digestion (AD) of the separately collected organic fraction of household waste (bio-waste), only a few data are available. The paper present...
Whey is just turning from a waste of milk processing to a renewable raw material in biotechnology for producing single-cell protein, bio-ethanol, or ethyl acetate as an economic alternative. Conversion of whey...
The proportion of biogas in the mix of renewable energies is still remarkably high. The process of anaerobic digestion (AD) provides the basis of biogas production but often leads to excessive foaming. Identif...
One of the most promising alternatives to gasoline as fuel in the transport industry is bioethanol, whether if it is conventional (based on raw materials containing sugar and starch) or produced from lignocell...
This article presents some crucial findings of the joint research project entitled «Storage of electric energy from renewable sources in the natural gas grid-water electrolysis and synthesis of gas components»...
In 2002, the provincial government of Ontario first announced plans to close all coal-burning thermoelectric generating stations. Facing the loss of local jobs should the local generating station close, Atikok...
This paper introduces the concepts, methods and the implementation of a calculator for the energetic long term analysis of residential settlement structures (ELAS). The freely available online tool addresses, ...
The political agenda on wind power usage intends its further expansion in a large scale. As most energy sources, wind power can have negative impacts on humans and environment; this expansion can be accompanie...
Energy scenarios that are used for policy advice have ecological and social impact on society. Policy measures that are based on modelling exercises may lead to far reaching financial and ecological consequenc...
The global demand for energy, particularly for transport fuels, will continue to increase significantly in the future. In addition to other options, like increased technological efficiencies, traffic reduction...
Environmental systems often have a very complex structure. Methods from computational intelligence (CI) that are often inspired by nature can help to improve these systems. On the one hand, CI methods can be u...
The chemical process industry, mainly the production of organic and inorganic base chemicals, has a significantly high demand for electrical and thermal energy. This demand is constant in time and quantity due...
An extrapolation of the world energy consumption from 1990 to 2010 indicates a complete exhaustion of the world reserves of oil, natural gas, uranium, and coal by 2043, 2047, 2051, and 2055, respectively. For ...
While the traditional form of electricity generation and supply is based on centralized structures with large-scale power plants, the objective of a strongly decentralized form of energy supply is increasingly...
Although the goals of the country’s energy transition (Energiewende) are widely accepted in Germany, the specific route to get there is itself a matter of great controversy. The individual measures that are part ...
This paper aims to identify specific local roadway infrastructure design guidelines associated with the construction and operation of sustainable energy source facilities, such as ethanol plants, biomass plant...
