About 50% of the power is lost in the transmission lines due to resistance.

Not possible - that much power loss through resistance, which would be converted to heat, would melt the whole electrical grid

High-voltage transmission is pretty efficient, only a 1-2% loss ... like the article says, the waste is at the ends

Energy lost in transmission and distribution: About 6% – 2% in transmission and 4% in distribution – or 69 trillion Btus in the U.S. in 2013
