What is the main form of energy used in the us in the 1800's
100
1. car pooling,public transportation,driving slower 2. hybrid or flex fuel cars using first generation bio fuels, ethanol from sugar cane or corn 3. more fuel efficient, lighter cars
What are 3 ways transportation can be more efficient, referring to reducing fuel consumed or green house gases emitted
100
solor,wind,biofuels(ethanol), hydrogen, hydropower,geothermal
what are examples of renewable energy
100
1950s
When did the us begin importing and producing uranium for nucular power. aulstria has the most uranium

What is the form of energy that peaked in the US around 1900-1910
200
hybrid - gasoline powered engine with electricity as back up power e-flex- electric car with back up generator powered by gas or other fuel
What is the difference between hybrid and e-flex vehicles?
200
a. photovolatic b.solor thermal c. solor concentrating systes
what are 3 types of solor energy
200
1960
When did US reach peak of uranium
200
fermintation
what process does ethanol produced through
300
oil 1st than coal and natural gases tied for 2nd
What is the most used forms of energy for the US in the year 2000?
300
they both rely on fossil fuels - plastics , coal generated electricity and gas/ethanol
What is a weakness of both hybrid and e-flex technologies?
300
we dont have the infrastructure to switch over to wind power not all places in the country are suitable for wind power requires alot of land which could be used for other purposes
What are 3 cons of solor and wind power
300
1980 and because of concerns about cost and public safty the three mile island 1979
in what year did they stop and why
300
brazil
whitch country produces the most ethanol
400
land disturbance, acid mine drainage, coal mine fires, land subsidence , air pollution, climate change
What are the 3 environmental issues associated with coal production
400
hot water and steam
geothermal energy generates electricity using
400
Fukushima and Chernobyl
give 2 examples of a level 7 on international nucular and radiolgical even scale
400
it still emmits 15% less carbon dioxide than fossil fuels , farmers choose to grow ethanol before corn n competes with food crops causing food price to rise
What are 2 drawbacks from ethanol from crops
500
less than a century
fossil fuel reserves represent how many years of primary production of terrestrial ecosystems?
500
Free-bates, parking incentives,federal and state incentives to buy
What are some policies tools that can influence transportation solutions?
500
damns , which channel water through turbines
hydrothermal energy generates power by
500
zero emissions , high energy yield cons uranium is not domestically available , high cost of construction , public safety concerns respect to plant operations, and waste disposal
what ar pros n cons of nucular energy
500
cellulosic ethanol requires less fertilizer and water than bio fuel from crops. doesn't interfere with food production. farmers can still grow crops
What are two advantages of ethanol produced from cellulose ,relative to corn ethanol
