Nonrenewable Energy Resources Flashcards
what are some pros to electricity
power plants are efficient, easy to transmit, does not directly pollute air when used
what are some cons to electricity
cant be stored, loss of energy from conversion, some forms of energy create pollution
what type of energy did they use in the pre industrial
muscles and firewood
what type of energy did they use in the industrial
burning wood, then coal
what kind of energy did they use in the post industrial
fossil fuels with some renewables
what is oil

OPEC (12 countries control more than 81% of the worlds oil)
how does fractional distillation work
seperates out components of crude oil by boiling point
what is natural gas made of
50-90 percent methane and 10-50 percent other gasses
how is natural gas mined
pumping out of the ground
where is natural gas found in the ground
above crude oil reserves
what are methane hydrates
methane trapped in ice crystals below permafrost or ocean sediments
