for example the equipment cost for a 10 kw wind turbine costs roughly $ 40000 while a 100 kw turbine can cost more than $ 350000 according to bergey com the average wind turbine can cost $ 48000 to $ 65000 to install
The boats can typically travel at speeds over 80 knots (150 km/h) in calm waters, over 50 knots (90 km/h) in choppy waters, and maintain 25 knots (47 km/h) in the average five to seven foot (1.5 to 2 m) Caribbean seas. They are heavy enough to cut through higher waves, although at a slower pace.
In the water, fish take the lead. Sailfish are the fastest in the water, at 70 miles per hour (113 km per hour) â the same speed in the water as cheetahs attain on land. Mako sharks can reach 60 miles per hour (97 km per hour), and marlins, 50 miles per hour (80 km per hour). The fastest mammal in the water is the killer whale, which can swim at up to 48 miles per hour (77 km per hour). Neither insects, reptiles, mammals, or terrestrial bird speeds come anywhere close to birds in flight. Birds are not only the fastest animals in the air: they are the fastest on Earth.
