Availability Reserves Usage Benefits Drawbacks Natural Gas -98% of the gas used in North America is produced in US and Canada. -there is 2,718 trillion cubic feet of natural gas for future supply. -this fuel source is cleaner than coal -it is more reliable and efficient. -it is an economical source of domestic use. -produced 45% less CO2 than coal. -dangerous if handled or transported carelessly. -due to its nature (odorless, colorless and tasteless), it is not easily detectable. -creates green house emissions. Coal -it is found in the US and accounts for 32% of US total energy production and 23% of total energy production. -found in 38 states, under 458,600 square miles or about 13 percent of the nation's land area. -The US. has 250-300 billion tons of coal reserves. -represents one quarter of world’s known reserves and 94% of US fossil energy reserve. -generates electricity Used to make cement. -it is a key feedstock to chemical industries as a raw material, fuel and power. -the average U.S. home uses 193 cubic feet of natural gas on a daily basis. -to make electricity. 9 out of every 10 tons of coal mined is used for domestic electricity and generates half of US electricity. -used to make 2.4 million metric ones of steel. -there is plenty of it -located in the US -it is cheap -its price is stable -reduces reliance on foreign fuel sources -provides jobs to its citizens Nuclear -US the largest producer of nuclear power. -US has more than 100 nuclear reactors that -As of 2008, the US uranium reserves were at 1 billion, 227 million pounds -electricity generation -it has lower green house gas emissions -reliable -powerful and efficient -generates electricity -if left unchecked and uncontrolled, can emit ash, sulfur dioxide and other harmful gases that are dangerous to the environment as well as health. -does not come in a ready to use form. It has to be processed for use -it requires a lot of water for processing which can pollute water sources for humans and animals. -emits gases that pollute the environment and can cause health problems. -its waste is linked to chronic diseases.
