Saturday musings - here's my PP's greenhouse gas (GHG) emissions for my zip code. Includes GHG emissions for both the car and production of electricity used to power the car. Source: Beyond Tailpipe Emissions
Ours is coal and natural gas I think. Florida is 70% NG. Nearest plant is NG. Mine came out at the national average of 160.
Here's for FL - Florida - State Energy Profile Overview - U.S. Energy Information Administration (EIA)
Found this for Texas, although I think it’s about energy usage in general, not electricity generation in particular: Curiously, Texas has the largest investment in wind of any US state, having both coastal wind and west-Texas desert winds. Looks like it’s still a fairly small percentage though.
Was reading this article. UGA study finds black carbon aerosols from GDI engines will worsen public health, climate; need for GPFs - Green Car Congress Is Prius including Prime engine gasoline direct injection (GDI) engine?
That's crazy how two sites would be so different. I looked at my page history to go back and double check what I saw and it's even crazier that that page isn't in my page history or search history. I can't seem to get back to it. Anyway, lots less coal, but almost the same percentage is natural gas. NG = 16938. Grand total = 22162. 16938/22162 = 76%
Lat month I posted a science news article on a new method to greatly reduce soot formation in diesels. No mention about how applicable it may be in gasoline engines. The basic theory should work, but fitting it with a small combustion chamber might be problematic. Ducted fuel injection to decrease diesel soot | PriusChat
The new engines in the Camry and Rav4 were the first to have DI, but they also have port injection, so should pass the particle limits, if that is ever applied to gas cars in the US. Some port injected engines have been measured exceeding the limits imposed on diesels, but they aren't visible to the naked eye, so the public doesn't worry.
Or, there’s this from the DoE Alternative Fuels Data Center: Looks like wind is not-insignificant percentage in Texas: Around 16%. You can get this “readout” for any state. I’m not sure, in the PHEV classification, what percentage they’re assuming for EV vs. HV driving. I’ll keep reading...
