Green energy even costs way less than oil and gas in many cases.</p> Green energy is definitely the best solution in most cases.

Although the relative costs of building coal vs. reflective solar plants may make going with solar prohibitive. Reflective solar seems the best way to generate the required heat, it can be sited at the plant to reduce the need for transporting electicity, etc. Another potential downside is need for round the clock production, liquid salt might not retain enough heat to power 3 shifts.</p> These plants should use a combination of reflective solar and wind energy.
