Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years...

The increased number of hazardous materials transportation accidents has caused a series of environmental and health problems across the world. In this paper, a hazardous materials transportation monitoring system (HMTM) is designed, implemented, and tested using multi-interface Wireless Sensor Networks (WSNs). In order to meet various state tanker transportation information collection, we desi...

Transportation is not only a key component of the tourism value chain, but it is also a critical management consideration in shaping tourism’s environmental footprint. Transportation consumes the greatest portion of the energy used in the tourism system. Most of this consumption is associated with travel to and from the destination. Despite this situation, scant research has addressed ways in w...

Concerns about depletion of fossil fuels and energy security have increased interest in renewable energy sources. Biogas, generated from anaerobic digestion of organic wastes, has a relatively low cost and is considered to be a renewable energy carrier. There is an increasing interest in converting biogas to “green” transportation fuels. This fact sheet discusses the technologies that are curre...
