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.
What really matters is the cost to society. With current subsidy methods, it costs around 3Â¢/kWh of subsidy to get wind turbines built [2011 update, Iâm now hearing from insiders that more like a 5Â¢/kWh subsidy may be required]. This is because the up-front costs of wind turbines are huge and the payback takes twenty years.
