Spicy foods can cause a burning sensation in the mouth, but your symptoms may be more pronounced if you have been diagnosed with burning mouth syndrome.
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.
Access is the predominant issue for wind turbine O&M, as the stark disparity between costs for onshore and offshore wind farms demonstrates. Operation and maintenance costs at onshore wind power sites now rival the simplest coal technologies at $46 per kW, and are expected to fall below the coal O&M price by 2020.
