Each method is evaluated from the following aspects: 1. Cost 2. Reliability 3. Safety 4. How green is each method 5. Highest energy outputs available Jones backs up his analysis with 16 notes on the limitation of off-shore wind turbines and supplies 32 references and links. Capers Jones is the founder of Namcook Analytics and creator of RiskMaster software, a predicting tool for analysis of software development projects. The graphs below summarize the data found in the linked file. Offshore wind is used as a reference for comparison. Natural gas and hydroelectric tend to lead all the other methods of electric generation in suitability and cost.

Deepwater Wind offers the worst possible solutions for Rhode Island— expensive energy generated by off- shore wind turbines that are not green, high risk and unsafe.
We asked respected author of 18 books and creator of a recognized software risk computer application to take a look at available methods of generating electrical energy. Capers Jones reviewed 26 alternative methods of generation and identified another 15 more that might be useful in the future.
6.  Susceptibility to terrorist attracts (foreign or domestic) 7.  Cost calculated by the US Department of Energy 8.  Projected costs in 2050, and 9.  Is it good for Rhode Island?

The data is scaled with the lowest numbers as the most preferable choices. This is why we call this graph, Unsuitability Rank. In plotting this graph we used the first six of the evaluation methods mentioned above. It is clear that offshore wind is the most unsuitable source of energy for Rhode Island.
We used to different methods for the complex task of calculating costs. Both produced similar results. Note that one graph uses “Small Wind” while the other uses, “Land-based Wind”. The latter includes both small units used for individual buildings as well as large land-based windfarms.

It is clear from the data that offshore wind is the worst possible solution for Rhode Island; now and in the future (2050). Better choices seem to include natural gas and hydroelectric energy generation sources.
