1. Question: LED (light emitting diode) technology is quickly becoming a commercially viable lighting option. An LED only uses 6-8 W of power to produce the same amount of light produced by a 60 W incandescent bulb. If a building used LED lighting instead of incandescent lighting, how would this affect the building's carbon footprint?
2. Question: Use the alternative energy sources of wind, geothermal and concentrated solar power to replace coal power. How many wedges can be realistically removed from the projected emissions graph? What is the total number of wedges that have now been removed from the graph?
3. Question: How many wedges are removed from the projected carbon emissions graph if all 49 000 000 km2 of Earth's farmland is farmed with conservation tillage techniques? Can this change remove the wedge and a quarter that remains?
4. Question: Who should decide if or when solar radiation management strategies should be implemented to engineer our climate?
5. Question: If enough people choose to purchase products that result in the emission of less greenhouse gases during their life-cycle, how do you think this will influence the products that companies choose to manufacture and offer to consumers?
6. Question: Electric cars are sometimes thought to be "zero emission", releasing little, if any, greenhouse gases into the atmosphere when they are used. Based on the knowledge you have gained by working through this lesson, why do you think electric cars can still contribute to climate change ?
7. With these climate wedges, we mostly focus on energy and transportation because those are our biggest sectors for carbon emissions. What are, at least, two other examples of sectors that we could include as wedges and how would they help to reduce carbon emissions?
