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 you save depends on the energy efficiency of your home and your local electricity rates. However, depending on your wind turbine system size, wind quality, permit and energy costs, and turbine performance, payback periods for small wind systems range from 6 to 15 years. Larger systems (10 kilowatt) can take 15 to 30 years to make up your initial costs.
