1) Bullsnot. Most of that electricity was generated by burning coal and methane.
2) I couldn't possibly care less anyway. Anthropogenic 'climate change' is a lie.
Actually, when the Prius saves CO2 emissions, it does so by higher efficiency. But all of its CO2 emissions come from gasoline, unless you have the plug-in hybrid version, which does have a small amount of CO2 coming from coal and methane, if you plug it in. But it won’t go far on the power from the plug, so a Prius mostly emits CO2 from gasoline, just less because of more MPG. That is where the CO2 savings he is referring to come from.
>>Since the Prius launched in 1997, Toyota says it has sold more than 20 million electrified vehicles worldwide. The company says those sales have avoided 160 million tons of CO2 emissions, which is the equivalent to the impact of 5.5 million all-electric battery vehicles.
Almost all of those 20 million electrified vehicles worldwide have been conventional hybrids. So all of that electricity has been generated by gasoline engines.
The CO2 emissions have been avoided because the hybrid powertrains are more efficient and get better gas mileage.
