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.
How much of the time do wind turbines produce electricity? A modern wind turbine produces electricity 70-85% of the time, but it generates different outputs dependent on wind speed. Over the course of a year, it will generate about 30% of the theoretical maximum output. This is known as its load factor. The load factor of conventional power stations is on average 50%.
