When you say "we", what I hear is "conservatives". Normal people are willing to change. Conservatives are not. And since they protect the billionaire class, we are all stuck.
Conservatives are killing us. They know this and mock us for being upset about it.
The first off-ramp we had to get off of fossil fuels was nuclear energy. It wasn't the conservatives who blocked that exit.
If nuclear energy buildup in the 1990s had followed the trend of the 1970s and 1980s, we could have kept CO2 below 400 ppm.
The three groups who conspired against that decarbonization were: the coal lobby, anti-nuclear activists and labour unions (because coal unions were strong back then).
Only one of those groups were the rich conservatives.
It is. Can't wait for something to actually stop fossil fuels and move us to new methods of transportation. The greed is pushing us toward our own demise.
Protip: if you're taking Viagra and the erection lasts more than four hours, it's vitally important to seek medical attention; an everlasting erection is a ticket to losing your genitals.
Every time we had a new energy source, we just added it to the mix. We always had to activly cut the usage of the old one to cause a decline. So renewables just can not grown fast enough to cause a decline in fossil fuels. They however can replace them, if we cut them in a smart way.
