Imagine if US gas prices went up overnight to $10/gallon. There would be riots. Jan 6th would look like a warm-up.
But does anybody realistically think that they can carbon-capture 1 gallon of gas's worth of carbon emissions for $7? How much would it realistically cost?
It's willful ignorance to think that we can continue to use the same amount of energy while waiting for technology to improve and become greener. We have the choice between immediate, painful cuts to energy usage ($20/gal gas), or doing irreparable harm to our planet. We are choosing the latter.
