I have 14 large solar panels on my barn roof, and make about 20kw/day. We have geothermal heating and cooling. We use it for cooling and some light heating, but hard core winter heating is done w/ wood (lots cheaper). We built our house out of ICF w/ CCF sprayed roof deck way thicker than necessary. We grow a lot of our own food. We also both drive big diesel trucks, because we need them to support the size of our family and the work that we do.
Exactly zero of the decisions leading to the procurement and use of those items had anything to do w/ carbon. We got them for utility, survivability of the house/family in natural disasters, and for cost savings.
I honestly don't know what to believe. I grew up in the 70's and 80's. In school they were teaching us about the next coming ice age and nuclear winters.
I'll say that things appear to be a heck of a lot cleaner, in the mid west anyway, than they were 25-30 years ago.
The recent "concerns" about carbon as a pollutant confound me a little. It's the same stuff that we breathe out and that trees breathe in. I'm highly suspicious of the scientific method being applied to this debate, as it's been co-opted as a political weapon. IMO, that never works out in the favor of anyone but the politicians.
I know there's tons of scientists that say we should be worried. I also know that many if not most of them are taking huge grants to study this from a gov't eager to promote it.
Here's the core part of the issue in my mind:
The entire world economy, as it exists today, is pretty much based on carbon-based fuels. If we want to reduce carbon emissions, we've got to have an economically viable alternative to these fuels in all of the needed forms: liquid, solid, electrical, gaseous, etc. Human civilization depends on this economy to continue to function with reasonably priced fuel sources.
If some technology were to materialize tomorrow that would run my truck and still be able to effectively pull 12000 pounds of trailer, for 1/2 the operating cost, I'd buy it immediately. Making my fuel more expensive w/ no viable alternative only drives up my costs, and what little I'm able to pass along to customers.
One side of this debate wants to reduce demand and use some alternative supply thats not commercially viable. The other side says "there ain't no problem, drill baby".
Neither of them are right I suspect. You can't tweek one side of the supply/demand curve and not get a reaction from the other side and/or price. We learned that in econ 101.
Raising my taxes isn't going to fix anything. Drilling holes isn't either. Time to move on to plan C, whatever that is — all the while de-politicizing the scientific debate so that it actual scientific debate.
Until then, we're just watching people beat the snot out of each other.
Sorry if my opinion doesn't quite square with everyone else's here. Thanks for reading this far.
