In terms of energy, I am in favor of using EVERYTHING. Oil, gas, coal, nuclear, hydroelectric, wind turbines, photovoltaic, even hydrogen power cells if they ever get it figured out. For now. We need them all.
In the future, the market will allocate capital to the most efficient and effective.
As to who manages energy production, the market will do the same for the same reasons.
Capitalism.
Not socialism.
