These factors including constniction costs fuel expense environmental regulations and financing costs can all be affected by government energy environmental and economic policies. Government decisions to influence or not influence these factors can largely determine the kind of power plants that are built in the future. For example government policies aimed at reducing the cost of constructing power plants could especially benefit nuclear plants which are costly to build. Policies that reduce the cost of fossil fuels could benefit natural gas plants which arc inexpensive to build but rely on an expensive fuel. The report provides projections of the possible cost of power from new fossil nuclear and renewable plants built in 2015. illustrating how different assumptions such as for the availability of federal incentives change the cost rankings of the technologies. None of the projections is intended to he a most likely case. Future uncertainties preclude firm forecasts. The rankings of the technologies by cost are therefore also an approximation and should not be viewed as definitive estimates of the relative cost-competitiveness of each option. The value of the discussion is not as a source of point estimates of future power costs but as a source of insight into lite factors that can determine future outcomes including factors that can be influenced by the Congress. Key observations include the following Government incentives can change the relative costs of the generating technologies. For example federal loan guarantees can turn nuclear power from a high cost technology to a .
