2. [2] Oil reserves have increased over the last few months, why? 3. [2] China is by far the world's largest producer of steel. Why did the IEA report focus on India? 4. [2] The GHG emissions for oil are divided into what three main categories? 5. [2] Approximately what % of the total emissions associated with Canada's Hibernia crude oil are a result of downstream use? Can this oil compete with oil from the Middle East on an emissions basis? 6. [2] In a few sections of this course we discussed working lifetimes of current infrastructure. In some cases, long working lifetimes present a challenge to meeting 2050 goals. Give two specific examples. 7. [3] Bill Gates highlighted greenhouse gas emission sources that will be persistent. Name three and indicate why they are likely to be persistent. 8. [5] When electricity comes from natural gas fired power plants, do electric cars make more sense than cars running on oil? To answer this, estimate the percent change in CO2 emissions one would achieve by switching from oil-fueled cars to electric cars. [Assume: Internal combustion engine efficiency = 32%, electric car motor efficiency = 90%, electrical grid transmission loss = 7%, ignore losses in oil transmission, and ignore differences between gasoline and oil].
