Renewables and Efficiency

Researchers have developed an artificial photosynthesis device that turns sunlight and water into two types of energy - hydrogen fuel and electricity.

Provides the foundations and principles needed for addressing the various challenges of developing smart cities. Smart cities are emerging as a priority for research and development across the world. They open up significant opportunities in several areas. such as economic growth. health. wellness. energy efficiency. and transportation. to promote the …

The generation of renewable electricity is becoming increasingly cost-effective and efficient so that a different set of challenges have arisen that need to be overcome. The most pressing of these is the development of viable. ‘green’ ways to store this energy as carbon-carbon bonds. Natural photosynthesis provides a ready blue …

Schneider Electric has won a $5.2 million contract to provide a microgrid for the nation’s second busiest port.

This book presents essential new governance structures to embrace and regulate smart mobility modes. Drawing on a range of case studies. it paves the way for new approaches to governing future transportation systems.    Over the past decades. Information and Communication Technologies have enabled the development of new mobility solutions …

The paper reports use of silicone oil as spectrum filter and heat absorber for photovoltaic thermal systems. The terrestrial solar spectrum is in the wavelength range of 0.25 to 2.5 μm. The response range of C-Si solar cell is 0.75 to 1.125 μm. In the current study. the feasibility of …

Purpose– Faults in the actual outdoor performance of Building Integrated Photovoltaic (BIPV) systems can go unnoticed for several months since the energy productions are subject to significant variations that could mask faulty behaviors. Even large BIPV energy deficits could be hard to detect. The purpose of this paper is to …

The basic component of two-circuit geothermal systems is the heat exchanger. When used in geothermal power systems. conventional shell-and-tube and plate heat exchangers cause problems related to the cleaning of the latter from salt-deposition and corrosion products. Their lifetime does not exceed. as a rule. 1 year. To utilize the …

Lifetime of wind turbine inverters is below expectations therefore. novel design and drive strategies are timely required to achieve optimum life span. In this work. a novel driving strategy to mitigate stresses on inverters is proposed. First. an electro thermal analysis was carried out using finite element modelling methods. Subsequently. …

ICF has been updating the Department of Energy’s CHP Installation Database for over a decade.
