Exam SCR topic 1 question 77 discussion

The statement (C) highlights that if the learning curve for battery storage technology does not improve over the next decade, the transportation sector could face technology risk. Battery storage advancements are essential for the widespread adoption of electric vehicles, which play a significant role in reducing greenhouse gas emissions and dependence on fossil fuels. Other options (A, B, and D) do not reflect the likely trends during the next decade: A. The levelized cost of energy for renewables has been consistently decreasing, making them increasingly competitive with fossil fuel energy generation. B. Solar and wind costs have decreased substantially, and they are becoming competitive without subsidies in many parts of the world. D. Replacing natural gas with coal would actually increase greenhouse gas emissions and transition risks, as coal is a more carbon-intensive energy source. The trend in the power sector is moving towards cleaner energy sources, such as renewables and natural gas, which emit less CO2 than coal.

B is flat out wrong. Solar and wind are doing great even without subsidies. C is right. This answer key was just crappy
