Wind turbine suffers catastrophic failure; no one is irradiated

Human error is inevitable in any system but can only have catastrophe consequences in particularly risky operations, such as, deep water drilling and nuclear power plants. Both of these activities are so risky that government liability caps (former) or 100% government financing (latter) are required before the private sector will touch them. Why should we, through the actions of our government representatives, assume these massive environmental and financial risks?
