The aim of the brainstorming session should be to generate the most ideas possible within a specific period of time. An effective brainstorming session will last anywhere from 15 to 45 minutes, and 30 minutes is usually ideal. The best number of participants for a brainstorming session is between four to seven people. Any less than four, and you run the risk of not having enough stimulation for creative thinking.
More affordable wind turbines range from $200 to $600. These turbines are typically smaller, which means less electricity is generated. Larger wind turbines can cost as much aâ¦s $2,000 for those used in the home and upwards of $20,000 for those used industrially.
In the early 1980s, when the first utility-scale wind turbines were installed, wind-generated electricity cost as much as 30 cents per kilowatt-hour. Now, state-of-the-art wind power plants at excellent sites generate electricity at less than 5 cents per kilowatt-hour.n the example above, the turbine would produce about 20 percent of its rated power at an average wind speed of 15 miles per hour (or 20 kilowatts if the turbine was rated at 100 kilowatts). This is somewhat lower than most modern wind turbines. back to the top.
