The government is considering whether to invest in the construction of a new onshore wind farm. Cost-benefit analysis is a commonly used policy evaluation tool, but is it the most appropriate for this context? Cost-benefit analysis can be used to compare the costs and benefits of a proposed project, but it may not be the best tool for this particular situation. Alternatives to cost-benefit analysis include risk analysis, cost-effectiveness analysis, and multi-criteria analysis. Each of these tools has its own advantages and disadvantages, and can be used to evaluate the potential investment in the construction of a new onshore wind farm.
