in 1890 a few efforts were made to generate electricity from wind power, but it was only in 1970 when energy prices rose steeply, that such a scheme was taken seriously. |
|
In I890, 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. |
|
It was in 1890 that the wind was first used to generate electricity, but it was long before 1970 when energy prices started to rise sharply, that real advances were made. |
|
Between 1890 and 1970 various attempts were made to harness power of the wind as the rising prices of energy made this desirable. |
|
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. |
