The Green New Deal isn't outlandish — it's a necessity

The basic roadmap is clear. Electricity should become emission-free, through a combination of renewables (wind, solar, hydro), nuclear and perhaps some carbon-capture and storage.

Light-duty vehicles should become electric, and heavy-duty trucks, ships and planes should run on some combination of zero-carbon fuels manufactured using clean energy. The electricity can manufacture hydrogen, which can be used directly (for example, in fuel cells or direct combustion) or combined with carbon to manufacture synthetic liquids and gases.

Yet to do this requires detailed planning, public infrastructure and systems-level design. It is actually not the decision of millions of individual consumers. They will buy electricity and drive cars. The technologies they will use will be zero-emitting, thanks to the genius of the engineers.
