cost of solar energy kwh

What does it cost per watt of solar energy?
This is for a science project and I am comparing wind power to solar power. Wind energy costs only $ 1/watt and $ 0.03-$ 0.05/kWh on average windspeeds of 6 m / s
and its estimate of wind turbines is a little low in practical applications. of 1 billion dollar 500-megawatt wind farm to be built in Iowa, Washington hopes to have a production cost of 093 per kWh. Here are some of the production costs for different types of plants. costs are given in cents per kWh. = 7.5 kWh nuclear super pulverized coal critical = 6.5 kWh. integrated gasification combined cycle coal (clean coal) IGCC plant = 7.2 kWh same with the capture of carbon = 7.9 to 9.3 kWh plants burning bio mass = 7.5 to 8.8 kWh of solar thermal power plants = 17.9 kWh silicon photovoltaic plants = 33.5 to 39.4 cents per kWh of film thin photovoltaic plants = 24.6 to 31.5 cents per kWh. BTW the biomass of plants currently in operation burning agricultural and industrial wastes ranging from Turkey manure sawdust
