| Question | Answer |
| CO2 levels need to stay below to keep temp from climbing too high | 550ppm |
| how much gCO2/kWh do wind, nuclear, and solar produce compared to coal and natural gas | wind: 12 Nuclear: 16 solar(photovoltaic): 48 natural gas: 469 Coal: 1001 |
| top 4 energy sources in US | natural gas, oil, coal, nuclear |
| how much energy in US is lost or wasted | 66% |
| how much energy obtained from petroleum for transportation is wasted? | 79% wasted |
| US carbon emissions in 2014 what % came from coal and petroleum | 74% |
| how much carbon emissions came from nuclear wind and solar in 2014 | ~0 |
| what source of energy used in the world is likely to decrease in future | coal |
| 3 countries that have "low" carbon emissions from electricity production same with high emissions | low: Russia, Canada, Brazil high: China, India |
| likelihood that hydroelectrric power will grow in US | pretty much none no much availability of places to create dams to generate |
| drawbacks to nuclear power | risk of accidents, people don't like, waste disposal |
| what energy sources are cheaper than coal? what is cheapest | hydro, wind, natural gas, geothermal, nuclear geothermal is cheapest |
| how do nuclear reactors generate electriciy | hit uranium with neutrons causing them to split creating 2 new atoms and creating heat, which generates steam and that goes into turbine |
| could a nuclear plant explode like nuclear bomb | no, uranium concentration isn't high enough |
| where are spend nuclear fuel rods stored in US? | stored on-site was being prepared: Yucca Mountain |
| why does the US no recycle nuclear fuel | carter decided not to have it done, prevents waste from being able to create bombs |
| Storm surge | wind blows water on land(bigger waves) |
| hurricane #s, hurricane rainfall rates, due to climate change | remain same or decrease slightly hurricane rainfall rates: increase hurricane intensity: increase |
| wind speed for category 5 hurricane vs category 1 | 1: 74-95 5: >= 157 |
| hurricane category caused most deaths | category 3(i.e. Fran, Katrina) weird that these were on this as katrina was category 4 but says that on slides |
| RCP 4.5 sea level rise | 20in(in 2100) |
| describe soil erosion on outer bank how fast? | water will erode and push it towards land (2-5ft / year) |
| beach renourishment | sand trucked in and added to beach, other methods are sea walls and groins |
