The conversation between human and AI assistant.
Which one is better - CRH (China Railway High-speed) or Shinkansen (Japanese Super Express)?
Which one is more environmentally friendly?
Both CRH and Shinkansen are considered eco-friendly transportation options. They both use electric power and emit less greenhouse gas than cars or planes. However, Shinkansen has been praised for its energy-efficient design, which has enabled it to reduce its power consumption by up to 30%. So, in terms of being environmentally friendly, Shinkansen may have an edge over CRH.
