THE successful integration of renewable energy into the power grid is expected to reduce the dependence of the grid on the fossil fuels. The potential renewable energy resources include light, wind, vibration, heat, biofuel, biomass, and tides [1], [2]. It is envisaged that the use of renewable energy will reduce the use of traditional energy resources, such as nuclear, oil, and gas, in the fut...

Iran has several potential for using renewable energies, so use them could significantly contribute to energy supply. The purpose of this paper is to identify the potential of the country and select the appropriate DG technologies with consideration the potential and primary energy resources in the regions. In this context, hybrid energy systems proportionate with the potential of different reg...

Alternatives to petroleum-derived fuels are being sought in order to reduce the world's dependence on non-renewable resources. The most common renewable fuel today is ethanol derived from corn grain (starch) and sugar cane (sucrose). It is expected that there will be limits to the supply of these raw materials in the near future, therefore lignocellulosic biomass is seen as an attractive feedst...

Faced with the increasingly serious energy and environmental crisis in the world nowadays, the development of renewable energy has attracted increasingly more attention of all countries. Solar energy as an abundant and cheap energy is one of the most promising renewable energy sources. While high-performance solar cells have been well developed in the last couple of decades, the high module cos...

Biocatalysts, capable of efficiently transforming CO2 into other more reduced forms of carbon, offer sustainable alternatives to current oxidative technologies that rely on diminishing natural fossil-fuel deposits. Enzymes that catalyse CO2 fixation steps in carbon assimilation pathways are promising catalysts for the sustainable transformation of this safe and renewable feedstock into central ...

This paper describes the development of a prototype knowledge discovery portal (KDP) for energy informatics. The research domain is Ireland which is increasingly challenged to achieve energy efficiency targets and to implement renewable energy systems (RES). The reasons for undertaken this research is to provide a mechanism to disseminate information on energy efficiency and renewable energy te...

— CSP technologies are well developed and offer many advantages compared to other renewable energy options. They can also be very effective in many locations with high solar radiation around the world. However today they are less competitive than other technologies. Understanding the limitations, and identifying opportunities for improvements, requires a detailed analysis of the energy conversi...

An essential element in a future UK low-carbon energy system will be electricity infrastructure that can facilitate more flexible demand, the balancing of variable renewable generation, and the incorporation of local small-scale technologies such as solar PV, and new technologies such as electric vehicles (e.g. ENSG 2009, DECC 2009, Cary 2010). Such ‘smart’ grid infrastructure will need to inco...

The promotion of renewable energy sources (RES) and ecologically clean technologies to reduce greenhouse gas emissions is a key policy of the European Commission. In isolated regions with great and unexploited RES potential, RES technologies can exploit local resources for electricity supply and substantial energy savings. The use of decision support systems (DSS) aims the multidimensional deci...

B ecoming independent of crude oil imports, mainly from the Middle East, is an urgent concern for many countries all over the world. In order to secure a sustainable energy supply, especially in the transportation sector, governments need to apply policies that promote the use of renewable energy technologies. The dependence on crude oil imports decreases as the production of total energy from ...
