We have a national choice to make. Either we allow ourselves to be the victims of change by taking no measures to wean ourselves from carbon fuel burning for our energy needs or we incentivize change away from carbon fuel use. There is a double whammy vs double benefit between these options. As a nation we depend on petroleum, coal and natural gas for the bulk of our energy use. These are GLOBALLY PRICED fuels. The US is becoming less and less influential on that global price! Biofuels are largely dependent on what we now use as food crops. If we use crop plant "waste" for the carbon fuels we deprive the soil we grow the crops on of much needed restorative organic matter, jeopardizing it's ability to sustain production of the crops.
Leaving carbon fuel use behind us will allow us to determine our own economic future instead of having it dictated to us by carbon fuel producing or consuming foreign economic powers.
Then there's the environmental damage of contributing to "Global Warming". There are serious arguments about the human influence on global temperatures rising and falling, but the science is pretty definitive of the currently rising temperatures world-wide. It seems ridiculousness to me that humanity would have no influence on at least the speed of that process by release into the atmosphere of trillions of tons of carbon that was stored for eons in subterranean deposits!
Here's a take on the consequences for our State of Illinois and opportunities for avoiding them, the "pay now or pay later" list.
