What are the costs of marine renewable technologies?
Naturally, costs vary with the type of technology. The MMS Whitepaper on Offshore Wind states that where once the cost of offshore wind was around forty cents/kWH, over the past twenty years, costs have dropped to between 4 and 6 cents/kwh. By 2012 and beyond, DOE envisions 5 MW and larger machines generating power for 5 cents/kWh.
