|
What % of US oil consumption is imported today
|
60%
|
|
|
What % of US oil consumption was imported just before the 1973-74 Arab oil embargo
|
22%
|
|
|
Name 3 of the 5 countries that supply the largest amount of US petroleum imports
|
Canada
Saudi Arabia Mexico Venezuela Nigeria |
|
|
What is the main feature of a natural gas-fired combined cycle plant that makes it more efficient than older designs
|
Uses gas and steam turbines
55-60% efficiency vs. 30-40% with traditional steam turbines |
|
|
What is the difference between uranium used in power reactors and uranium used in nuclear (fission) weapons
|
Power plants use 20% enriched uranium or less (uranium with elevated percentages of U-235 which is capable of fissioning which U-238 is not)
Too much U-238 inhibits the runaway nuclear chain reaction that is responsible for the weapon's power |
|
|
What is the Renewable Electricity Standard (RES)
|
Requires electricity suppliers to produce a certain percentage of generation from renewables (25 states currently have)
|
|
|
What are the principal rationales for proposing a national RES
|
Increase fuel diversity, reduce CO2 emissions and improve environmental quality, improve marketplace efficiency by providing a common policy foundation, provides basis for an effective national portfolio standard
|
|
|
How many US nuclear reactors are there
|
104
|
|
|
What % of US electricity do nuclear reactors provide
|
19-20%
|
|
|
When was the last nuclear power plant ordered in the US
|
1978
|
|
|
How many new nuclear power plant applications have been received in the past few years and what region of the country are most of them proposed to be located in
|
4.5 in the SE
|
|
|
When was the Nuclear Non-Proliferation Treaty signed?
|
1970
|
|
|
What are the two categories of member-states in the Nuclear Non-Proliferation Treaty and what do they each agree to
|
Non-nuclear weapons states: in exchange for not developing nuclear weapons, non-weapons states receive nuclear power assistance
Nuclear weapon sates (US, Russia, UK, France, China): agree not to share or sell nuclear weapons information to states without programs and reduce the number of arms they have in their arsenals and aid non-nuclear weapons states to develop peaceful nuclear power |
|
|
Describe the major features of the Global Nuclear Energy Partnership. Why is it seen as a potentially proliferation resistant system
|
The US works with nations that have advanced civilian nuclear energy programs (France, Japan, Russia) to develop and deploy innovative, advanced reactors and new methods to recycle spent fuel in partner states
Increased transportation of nuclear fuels and the plan is ahead of the technology as fast breeder reactors are not yet available |
|
|
Describe what type of fuel is being produced at the North Dakota/Weyburn site and how carbon dioxide is being sequestered
|
Use crushed lignite coal in "gasifiers" where its mixed with steam and oxygen and then burned to break down the coal and produce a mixture of gases. A pipeline from Weyburn to Canada allows an oil field to use the CO2 for enhanced oil recovery
|
|
|
Amory Lovins wrote a article in 1976 titled "Energy Strategy: The Road Not Taken" What does the title mean
|
Extrapolation of the recent past, expanding centralized technologies to increase energy supplies
Prmopt and serious commitment to energy efficiency and renewable energy |
|
|
What are the top three energy resources used for electricity production in the US
|
Coal (50%)
Natural gas (20%) Nuclear (20%) |
|
|
What type of energy resources has dominated new power plant construction in the US over the past 5-10 years
|
Natural gas becuase its highly efficient with combined cycle designs, relatively cheap, and less pollution and lower carbon dioxide emissions then coal
|
|
|
Name two types of geological carbon sequestration that are profitable today
|
Methane recovery from coal mines
Enhanced oil and natural gas recovery: CO2 is piped into oil and gas wells to allow the oil and gas to be extracted more quickly and more completely |
