GC: n CT: In Europe, we currently use 16 tonnes of material per person per year, of which 6 tonnes become waste. Although the management of that waste continues to improve in the EU, the European economy currently still loses a significant amount of potential ‘secondary raw materials’ such as

GC: n CT: Every year, billions of dollars of energy are thrown away as waste heat. Heat is the natural by-product of energy conversion processes; both conversion of primary fuels to work or energy, and conversion of energy to work. Of the 100 quadrillion BTU’s of energy the US consumes

GC: n CT: Waste of electrical and electronic equipment (WEEE) such as computers, TV-sets, fridges and cell phones is one the fastest growing waste streams in the EU, with some 9 million tonnes generated in 2005, and expected to grow to more than 12 million tonnes by 2020. WEEE is

GC: n CT: We consider wastewater treatment as a water use because it is so interconnected with the other uses of water. Much of the water used by homes, industries, and businesses must be treated before it is released back to the environment. If the term “wastewater treatment” is confusing

GC: n CT: A tool that has been developed for the calculation of water needs for consumer products is the concept of the water footprint (WF). This tool has been introduced by Hoekstra and Hung (2002) and has been developed further by Hoekstra and Chapagain (2007, 2008). Those authors define

GC: n CT: Water hammer is a pressure surge or wave caused when a fluid (usually a liquid but sometimes also a gas) in motion is forced to stop or change direction suddenly (momentum change). As soon as steam leaves the boiler, it starts losing heat. As a result, steam

GC: n CT: A watershed is the area of land where all of the water that is under it or drains off of it goes into the same place. John Wesley Powell, scientist geographer, put it best when he said that a watershed is: “that area of land, a bounded

GC: n CT: Photovoltaic solar panels produce power through generation of watts of energy. Panels come in different “strengths” or wattage levels. Solar panel sizes vary from very low wattage levels up to 280 watts worth of power. Solar systems are sold as complete installs by watt. This includes the

GC: n CT: A wave power generator that can harvest energy no matter which way the sea is running has won the UK round of James Dyson’s engineering award. The Renewable Wave Power generator seeks to overcome the limitations of some current wave power technologies. These work best when struck

GC: n CT: As the climate change conference continues in The Hague, it is perhaps fitting that the world’s first commercial wave power station is going into action in Scotland. The power station, on the island of Islay, is the product of years of research into how to effectively harvest
