Well, yes, it is, until you get to complex pages with dynamic content. Think about on-site search results, Flash content, forms, animations and other dynamic resources. There are many reasons why a web crawler would not see your website in the same way that your human visitors do. In fact, many businesses take steps to ensure that web crawlers âseeâ all of the content available.
All estimates for wind power include the cost of purchasing capital and paying for operations and maintenance (O&M) of wind turbines. For the studies we examined, capital costs ranged from $48 to $88 per megawatt-hour, while O&M costs ranged from $9.8 to $21 per megawatt-hour.
The power a wind turbine can generate is proportional to the cube of the wind speed (until you reach the maximum power limit of the generator attached to the turbine). But even if you ask for the average of the cube of the wind speed, that really isn't all that useful either. Anyone wanting to build a wind turbine will look for sites where the wind speed is high a lot of the time. They won't put it where the winds are average.
