Energy Resources I By: Francesca Braganza :/http/lunar.thegamez.net/greenenergyimage/definition-of-renewable-energy-resources/definition-of-renewable-and-nonrenewable-energy-resources- 1060x864.jpg

When did we start producing electricity? History of electrical power began on August 26, 1895, water flowing over Niagara Falls diverted into high-speed turbines coupled to two 5,000-horsepower generators produced at about 2200 volts used locally for the manufacture of aluminum and carborundum the following year, it raised to 11,000 volts and transmitted twenty miles by wire to the city of Buffalo it was used for lighting and street cars

How is electricity produced from traditional sources? known as nonrenewable energy resources cannot easily be replenished /grown unlike renewable energy resources or biofuels. include: - oil -Coal - natural gas dominated energy consumption for the last century. Each combust The burning of coal, natural gas and oil using gas turbines or heat engines produces heat when combined with steam generates electricity

major aspects in electrical power production Most energy comes from traditional energy sources coal and gas

Environmental impacts Coal, natural gas and nuclear power add pollutants to water if discharged can negatively impact water quality and harm wildlife result in water pollution. Coal produces waste called ash Adds to the pollution during mining process Drilling and extraction of natural gas results in leakage of methane far more potent global warming gas than CO 2

What is the difference between sustainable and unsustainable sources of energy? Unsustainable energy -can be used in the next 200 years -(coal,oil and natural gas) Sustainable energy -Can and could be used forever -w/o CO 2 and other harmful gas release - (solar and wind) sunset.jpg

Are nuclear and hyrdroelectric plants sustainable?

climate-friendly energy source generates power w/o producing air pollution avoids approximately 200 million metric tons of carbon pollution each year Communities that rely on hydropower Benefits cleaner air and water. Hyrdroelectric dams

Nuclear power plants heat generated through the fission process of atoms. convert heat into electricity using steam heat to make the steam created when atoms split apart (called fission) Fuel for fission uses Uranium low carbon emission characteristic to be defined as renewable energy One of the arguments against it -uranium deposit -finite To be counted as renewable energy source (fuel) should be sustainable indefinite period of time according to the definition of renewable energy
