Renewable Energy In Canada
, renewable energy technologies provide about 17.3% of Canada's total primary energy supply. For electricity renewables provide 67%, with 15% from nuclear and 18% from hydrocarbons. The majority of renewable energy produced in Canada comes from hydroelectricity. It supplied 58% of total electricity production in 2016 making Canada the second largest producer of hydroelectric power globally. Wind power is a fast-growing sector, accounting for 5% of electricity production in 2016. Globally, Canada was the eighth largest producer of wind power in 2016. Canada has also built photovoltaic power stations, mainly in Ontario, with one in Sarnia, being the largest in the world at the time of its construction. A 15-megawatt tidal plant sits at Annapolis Royal, Nova Scotia, and uses the daily tides of the Bay of Fundy to generate electricity.

Buildings And Structures In Toronto
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toronto Water
Toronto Water is the municipal division of the City of Toronto under Infrastructure and Development Services responsible for the water supply network, and stormwater and wastewater management in Toronto, Ontario, Canada, as well as parts of Peel and York Regions. History Early days Water treatment was originally established in order to provide safe drinking water. In the 19th century, the water off the city's shores was severely polluted by the dumping of waste from residences and businesses. Before 1842, Toronto's water supply was manually pumped from Lake Ontario, streams and wells. Water carters would take the water and distribute it to customers across the city. Private water supply From 1843 to 1873, water was privately provided by Furniss Works or Toronto Water Works, a subsidiary of Toronto Gas Light and Water Company, which was owned by Montreal businessman Albert Furniss. Following Furniss's death in 1872, the City of Toronto bought out Furniss Works and transformed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ashbridges Bay Wastewater Treatment Plant
The Ashbridges Bay Wastewater Treatment Plant is the city of Toronto's main sewage treatment facility, and the second largest such plant in Canada after Montreal's Jean-R. Marcotte facility. One of four plants that service the city of Toronto, it treats the wastewater produced by some 1.4 million of the city's residents and has a rated capacity of 818,000 (design capacity of 1,000,000) cubic metres per day. Until 1999 it was officially known as the Main Treatment Plant. The plant has a 185 m (607 ft) high smokestack which is visible from most parts of the city. The plant opened in 1910. Prior to this, Toronto's sewage flowed directly into Lake Ontario and a layer of thick sludge covered the lake to a distance of several hundred feet from shore. The lake was also the source of the city's drinking water and the pollution contributed to a major typhoid outbreak. The plant is located on the shore of Lake Ontario at the foot of Leslie Street at Ashbridge's Bay. To the west is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Legionella Pneumophila
''Legionella pneumophila'' is a thin, aerobic, pleomorphic, flagellated, non-spore-forming, Gram-negative bacterium of the genus ''Legionella''. ''L. pneumophila'' is the primary human pathogenic bacterium in this group and is the causative agent of Legionnaires' disease, also known as legionellosis. In nature, ''L. pneumophila'' infects freshwater and soil amoebae of the genera ''Acanthamoeba'' and ''Naegleria''. The mechanism of infection is similar in amoeba and human cells. Characterization ''L. pneumophila'' is a Gram-negative, non-encapsulated, aerobic bacillus with a single, polar flagellum often characterized as being a coccobacillus. It is aerobic and unable to hydrolyse gelatin or produce urease. It is also non- fermentative. ''L. pneumophila'' is neither pigmented nor does it autofluoresce. It is oxidase- and catalase-positive, and produces beta-lactamase. ''L. pneumophila'' colony morphology is gray-white with a textured, cut-glass appearance; it also requires cyst ...

Cooling Towers
A cooling tower is a device that rejects waste heat to the atmosphere through the cooling of a coolant stream, usually a water stream to a lower temperature. Cooling towers may either use the evaporation of water to remove process heat and cool the working fluid to near the wet-bulb air temperature or, in the case of ''dry cooling towers'', rely solely on air to cool the working fluid to near the dry-bulb air temperature using radiators. Common applications include cooling the circulating water used in oil refineries, petrochemical and other chemical plants, thermal power stations, nuclear power stations and HVAC systems for cooling buildings. The classification is based on the type of air induction into the tower: the main types of cooling towers are natural draft and induced draft cooling towers. Cooling towers vary in size from small roof-top units to very large hyperboloid structures (as in the adjacent image) that can be up to tall and in diameter, or rectangula ...

Glycol
A diol is a chemical compound containing two hydroxyl groups ( groups). An Aliphatic compound, aliphatic diol is also called a glycol. This pairing of functional groups is pervasive, and many subcategories have been identified. The most common industrial diol is ethylene glycol. Examples of diols in which the hydroxyl functional groups are more widely separated include 1,4-butanediol and 1,3-Propanediol, propylene-1,3-diol, or beta propylene glycol, . Synthesis of classes of diols Geminal diols A geminal diol has two hydroxyl groups bonded to the same atom. These species arise by hydration of the carbonyl compounds. The hydration is usually unfavorable, but a notable exception is formaldehyde which, in water, exists in equilibrium with methanediol H2C(OH)2. Another example is (F3C)2C(OH)2, the hydrated form of hexafluoroacetone. Many gem-diols undergo further condensation to give dimeric and oligomeric derivatives. This reaction applies to glyoxal and related aldehydes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Street Pumping Station
John Street is a street in Downtown Toronto. It runs from Stephanie Street and Grange Park in the north to the Metro Toronto Convention Centre on Front Street in the south. It is home to a number of Toronto's cultural institutions, including buildings for the CBC, CTV, Toronto International Film Festival. The ''National Post'' has described it as "Running directly through the entertainment district, its spine connects many great cultural institutions, popular retail outlets, restaurants and soon-to-be-built condos." The City of Toronto has dubbed the street a "Cultural Corridor" and a report calls it "the centrepiece of the Entertainment District." History John, and other streets in the area, were named after John Graves Simcoe, the founder of York (today Toronto) and the first Lieutenant Governor of Upper Canada. During the typhus epidemic of 1847, 863 Irish immigrants died of typhus in fever sheds at the Toronto Hospital on the northwest corner of King and John Street. Route ...

Heat Exchangers
A heat exchanger is a system used to transfer heat between a source and a working fluid. Heat exchangers are used in both cooling and heating processes. The fluids may be separated by a solid wall to prevent mixing or they may be in direct contact. They are widely used in space heating, refrigeration, air conditioning, power stations, chemical plants, petrochemical plants, petroleum refineries, natural-gas processing, and sewage treatment. The classic example of a heat exchanger is found in an internal combustion engine in which a circulating fluid known as engine coolant flows through radiator coils and air flows past the coils, which cools the coolant and heats the incoming air. Another example is the heat sink, which is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium, often air or a liquid coolant.

Northeast Blackout Of 2003
The Northeast blackout of 2003 was a widespread power outage throughout parts of the Northeastern and Midwestern United States, and most parts of the Canadian province of Ontario on Thursday, August 14, 2003, beginning just after 4:10 p.m. EDT. Most places restored power by midnight (within 7 hours), some as early as 6 p.m. on August 14 (within 2 hours), while the New York City Subway resumed limited services around 8 p.m. Full power was restored to New York City and Toronto on August 16. At the time, it was the world's second most widespread blackout in history, after the 1999 Southern Brazil blackout. The outage, which was much more widespread than the Northeast blackout of 1965, affected an estimated 10 million people in southern and central Ontario, and 45 million people in eight U.S. states. The blackout's proximate cause was a software bug in the alarm system at the control room of FirstEnergy, an Akron, Ohio–based company, which rendered operators una ...
