Green technologies (e.g., wind, solar and electric vehicles) cannot compete in the marketplace without subsidies or other favorable government policies.
In Nevada, for example, when the government modified its policy to pay customers less for excess power produced by rooftop solar systems, solar installers left the state for others providing more favorable net metering policies. With its solar installations down, Nevada's legislature recently passed a net metering bill, which the Governor is expected to sign, that brings back net metering at a slightly discounted rate.
