GC: n CT: A carbon credit (often called a carbon offset) is a financial instrument that represents a tonne of CO2 (carbon dioxide) or CO2e (carbon dioxide equivalent gases) removed or reduced from the atmosphere from an emission reduction project, which can be used by governments, industry or private individuals

GC: n CT: Researchers are developing a new kind of geothermal power plant that will lock away unwanted carbon dioxide (CO2) underground – and use it as a tool to boost electric power generation by at least 10 times compared to existing geothermal energy approaches. The technology to implement this

GC: n CT: A carbon footprint is defined as the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). In other words, when you drive a car, the engine burns fuel, which creates a certain amount of

GC: n CT: Application for the promotion of renewable energy sources: Scientists have developed the first low-cost system for splitting carbon dioxide into carbon monoxide and oxygen, a process crucial if we want to ramp up renewable energy use in the future. This splitting process has long been identified as

GC: n CT: A carbon sink is anything that absorbs more carbon that it releases, whilst a carbon source is anything that releases more carbon than is absorbed. Forests, soils, oceans and the atmosphere all store carbon and this carbon moves between them in a continuous cycle. This constant movement

CG: n CT:  Carbon-14 dating Radiocarbon dating, or carbon-14 dating, is a method for determining the age of a substance containing organic molecules by using the properties of radiocarbon, 14C, a radioactive isotope of carbon. The technique was developed in the late 1940s at the University of Chicago by Willard Libby,

CG: n CT: Carbon is the main element of all biological processes. Natural carbon consists predominantly of the stable isotope 12C. The isotopes 10C and 11C have half-lives, 19 s and 20.5 min, respectively, and half-life of 14C is 5730 years. At its decay, 14C emits only beta particles with the

GC: n CT: Cathodic protection is employed intensively on the steel drains in oil and gas industry. It is a technique of prevention against the corrosion which transforms the structure into a cathode of a corrosion cell ; Two types of cathodic protection systems are usually applied : The galvanic

GC: n CT: Photosynthetic algae use sunlight to convert CO2 into natural oils that are suitable for conversion into biodiesel. However, harvesting the algae and extracting the oil are currently difficult and expensive operations. Cheaper and more energy efficient processes are required before mass production of algae can be used

GC: n CT: The economic feasibility of central photovoltaic power plants is investigated from the perspective of an electric power utility company. The maximum acceptable price of the system is established, as a function of conventional fuel costs. Factors which would enhance the economic attractiveness of the system are analyzed.

GC: n CT: Charcoal is a fine, black powder made from wood or other natural materials by heating them in an airless environment. Charcoal used for health conditions is usually “activated” to make it a very fine powder, which increases its effectiveness. Activated charcoal can chemically attach, or adsorb, to

CG: n CT: To properly inform the planning and deployment of charging infrastructure, there are many interdependent and often contradicting aspects that should be considered to quantify the performance of charging pools: Being motivated by the need to innovate the road transport that is based on fossil fuels, from the

CG: n CT: Chat refers to the process of communicating, interacting and/or exchanging messages over the Internet. It involves two or more individuals that communicate through a chat-enabled service or software. Chat is also known as chatting, online chat or Internet chat.

GC: n CT: The check valve was designed with a drive shaft that connects the internal valve disk to an external pneumatic cylinder. The valve failed when a dowel pin designed to fasten the drive shaft to the disk sheared and a key designed to transfer torque from the drive

GC: n CT: Many energy sources commonly used by humans are forms of chemical energy. They are usually labeled “fuels.” The way to use the chemical energy in most fuels is by burning them, as we do with wood, natural gas, gasoline, coal, and others. When these fuels burn, they

GC: n CT: Nobel Prize-winning chemist F. Sherwood Rowland probably never intended to be an environmental whistle-blower. But in the 1970s, when he and his postdoctoral associate Mario Molina at the University of California-Irvine studied a set of compounds called chlorofluorocarbons, or CFCs, they realized that they had uncovered a

GC: n CT: The circuit breaker is an absolutely essential device in the modern world and one of the most important safety mechanisms in your home. Whenever electrical wiring in a building has too much current flowing through it, these simple machines cut the power until somebody can fix the

GC: n CT: A circular economy is an alternative to a traditional linear economy (make, use, dispose) in which we keep resources in use for as long as possible, extract the maximum value from them whilst in use, then recover and regenerate products and materials at the end of each

GC: n CT: Nearly every aspect of our daily lives – heating, lighting, cooking, communications, transportation, commerce – depends on electricity. Unfortunately, generating that electricity through the use of traditional fossil fuels can be economically and environmentally costly and a danger to public health. Electricity generated with fossil fuels, such

GC: n CT: Clearcutting means the felling and removal of all trees from a given tract of forest. One forestry expert refers to the practice as “an ecological trauma that has no precedent in nature except for a major volcanic eruption.” Clearcutting can destroy an area’s ecological integrity in a

GC: n CT: The Fifth Assessment Report (AR5) provides a clear and up-to-date view of the current state of scientific knowledge relevant to climate change. It consists of three Working Group (WG) Reports and a Synthesis Report (SYR) which integrates and synthesizes material in the WG reports for policymakers. The
