The energy choices that we make today will affect us until 2050 and if they are dirty choices they may leave their impact for tens of thousands of years. (A power plant's life is about 40 years.)

Tony Seba provides a framework and walks through our choices (bioenergy, wind, geothermal, hydro-electric, nuclear, solar...) to reach an unequivocal conclusion.
