The harnessing of the wind to generate electricity dates back to 1890, but few notable advances were made until 1970 when energy prices began to rise fast.

A) In 1890 a few efforts were made to produce electricity from wind power, but it was only in 1970 when energy prices rose steeply, that such a scheme was taken seriously.
B) In 1970, when there was a sudden increase in energy prices, efforts were made to harness the power of the wind for the generation of electricity for the first time since 1890.
C) It was in 1890 that the wind was first used to generate electricity, but it was only in 1970 when the energy prices started to rise sharply, that real advances were made.
D) Between 1890 and 1970 various attempts were made to harness the power of the wind as the rising prices of energy made this desirable.
E) Impressive advances in the generation of electricity from wind power coincided with rising energy prices in 1970, but the practice actually dates back to 1890. 1996 kpds kasım 80.nci soru
