TECO Energy's main subsidiary, Tampa Electric, is planning to expand the Polk Power Station to serve future electricity needs. Plans call for converting the four natural gas-fired combustion turbines into a more efficient combined-cycle unit. If we get all the necessary approvals, the $700 million project is scheduled to be running by early 2017.
The circumference of the Earth is 24,902 miles (40,075.16 km). Over the poles it is more precisely 40,008 km or 24,860 statute miles. The actual unit of measure used by Eratosthenes was the stadion.
The circumference of Earth at the equator is about 24,902 miles (40,075 km), but from pole-to-pole â the meridional circumference â Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid.arth is the densest planet in the solar system because of its metallic core and rocky mantle. Jupiter, which is 318 more massive than Earth, is less dense because it is made of gases, such as hydrogen.
