No, power generation is about a quarter: https://www.epa.gov/ghgemissions/sources-greenhouse-gas-emis...

Transportation could push that total to 50% if all ICE cars were converted or destroyed and only electric vehicles were used (ignoring ships and trains). "Industry" includes CO2 waste byproducts which are much harder to reduce as many processes may struggle to eliminate that byproduct. Instead capture and sequestration would be needed. This is another 25%

The rest are small, but since we need virtually all CO2 emissions to be zero, we are left with nearly another 25% that isn't tied to electric production and is difficult to replace.

So, 50% of all CO2 isn't power generation related.
