Transcript of ELECTRICITY
What's The Difference ?
When was electricity discovered?
In 1879, the American inventor Thomas Edison was finally able to produce a reliable, long-lasting electric light-bulb in his laboratory.''
basic principals behind that particular form of electricity generation
Nuclear reactors, which produce heat by splitting uranium atoms, do the same job as typical power sources. They produce heat to change water into steam. The steam spins a turbine or generator to make electricity instead of coal, oil or natural gas, Ontario’s nuclear reactors use natural uranium in CANDU reactors. CANDU stands for Canada Deuterium Uranium. (Deuterium is just another word for heavy water)
What is electricity?
A form of energy resulting from the existence of charged particles (such as electrons or protons), either statically as an accumulation of charge or dynamically as a current.
Any resource that can be replenished naturally in a course of time.
Natural resource from the Earth that exists in limited supply and cannot be replaced if it is used up
Solar : Comes from sun. It depends on weather sun is out.
Coal : In the coal mines. So harder then solar power but easier then other resources
Solar : The cost seem to be going down. The grid tiles generate 815 KW a month and that would cost about 10,500 dollars.
Coal : A new coal plant would be around 3,500 dollars per KW.
Solar : Photovoltaic panels convert the suns rays to produce electricity.
Coal : water turned into steam, which drives turbine generators to make electricity.
Cleanest energy source
Burns fossil fuels
top source of CO2
primary cause of global warming
Solar : Solar power plants like a solar farm with High production and lots pf sun.
Coal : Warming, Boilers and turbines
Solar : Inverters, Solar panels and lots of sunlight needed.
Coal : Drag lines,Shovels, Loaders, Haul Trucks, High wall Miner, Blast hole Drills, Dozers and Graders
Nuclear energy helps ensure that Ontario is provided with safe, clean, reliable and affordable electricity for the future.
An induced fission reaction. A neutron is absorbed by a uranium-235 nucleus, turning it briefly into an excited uranium-236 nucleus, with the excitation energy provided by the kinetic energy of the neutron plus the forces that bind the neutron. The uranium-236, in turn, splits into fast-moving lighter elements (fission products) and releases three free neutrons. At the same time, one or more "prompt gamma rays" (not shown) are produced, as well.
What are the raw
The reactor uses the splitting of uranium atoms to generate heat to make steam
Water is used to slow down neutrons enough so that they strike other nuclei and sustain a controlled chain reaction
What energy conversion must take place?
Uranium contains a significant amount of energy. Fissioning or splitting one Uranium atom releases 400,000 times more energy than burning one atom of Carbon. Heat is produced by a fission in a nuclear reactor and then water vapor//steam is produced. The pressurized steam is then usually fed to a multi stage steam turbine.
What properties allow this conversion
Chemical properties allow for this conversion because the uranium atom interacts with a neutron to form three products, which are not uranium.
QUEBEC VS ONTARIO
Quebec makes a lot of electricity from hydro power, more than other provinces and other provinces buy it from them. Quebec is the largest electricity generator in Canada. They actually have 60 hydroelectric generating stations.
Hydroelectric power, nuclear, gas, coal,wind, solar. nuclear power is one of our most generated power in Ontario.
IMPORTANT FACTORS IN ELECTRICITY PRODUCTION
Solar : Sunshine everyday so not far north and needs lots of open space
*Cells & batteries use chemicals to kick start current
Hydro : Large water sources such as Niagara Falls and Northern Quebec
*Space shuttles use current electricity
Wind : Open flat areas like Prairies
Tidal : coastal areas
*Scientist use electrical waves to learn more about animals
