So many years ago I would walk to work (didn't even bother with transit). Driving my car would have made no sense (parking, ug). Those were the salad days, indeed.I am jelly....
and it has custom paint detailing in the wheel wells _AND_ laser etched in the plastic hte word _Cadillac_ definately worth $40,000 more than the Volt.Once a week? Really? We bought three tanks of gas for our ELR in a year. It's was a near perfect around-town car with a fit and finish that runs circles around our top-o-the-line Model S. Cadillac just got a little too greedy on the pricing, or it would still be a contender. Road trips with gas and electric for daily commute.

\rant onYou've obviously never set foot in an ELR.
Regarding cheap hydro power.....I got an email from Patagonia regarding Hydro Power Dams.
TVA’s Generating Assets Today
- 7 fossil plants (29 active units)
- 3 nuclear plants (7 units)
- 29 hydro plants (109 units)
- 1 pumped storage hydroelectric plant (4 units)
- 9 natural gas combustion turbine gas plants (85 units)
- 7 natural gas combined cycle gas plants (15 units)
- 1 diesel generator site (5 units)
- 15 solar energy sites
- 1 wind energy site
It's not practical for solar to make up 39% of power from a provider unless there are means to store all that power for use at night. Maybe batteries are the solution but more than likely energy storage in the form of pumped water would be more practical.
Last year Tucson Electric Power was able to get solar with 4 hr storage window at $45/MWh (4.5c/kWh) with delivery starting end of next year. The bids Xcel in CO got in December, for delivery in 2021, blow that out of the water (although length of storage window isn't clear from what I've seen released so far). In Colorado, a glimpse of renewable energy’s insanely cheap futureIt's not practical for solar to make up 39% of power from a provider unless there are means to store all that power for use at night. Maybe batteries are the solution but more than likely energy storage in the form of pumped water would be more practical.
That's what wind is for. When the sun goes down, wind comes on for the night shift. Local climate wind patterns apply but it's a general rule of thumb wind production is better at night. That (along with some wind power incentives) is why TX, with all it's West TX wind, will occasionally see grid spot prices go negative overnight. There has been a lot of wind generation brought online, to the point it's now at 17% of total generation exceeding the 10% share of total generation of nuclear.Will be pretty impressive if it can actually store enough to be able to power the grid at night especially as in theory more and more EVs mean more demand at night vs currently.
PV is ebbing at this time. It will be filled (geography prevails here) by a mixture of CSP, hydo, NG, wind and battery.On the other hand solar is an good fit for the "duck", consisting of A/C and people working and cooking supper.
....is currently double the cost of PV diurnal. It has potential, and can overnight & even 24hr so good chance it has a future is some regions, but it's still working on the goal of breaking through $60/MWh.
I meant that the sun is setting at supper timeIt's not "ebbing at this time"
another graphic for 2016For the average US electricity user it's a small percentage anyway
Actual numbers from 2017 annual production were
Nat gas (32%) 1,272,864,000 MWh
Coal (30%) 1,207,901,000 MWh
Nuclear (20%) 804,950,000 MWh
Hydro (7.5%) 300,045,000 MWh
Wind (6%) 254,254,000 MWh
All Solar (2%) 77,097,000 MWh
with Solar gaining ground on everything
2014 to 2017 increase or decline in order of most produced to least produced
Only a matter of time until Solar moves ahead of Wind and Hydro. Add a few more years and it'll pass Nuclear and Coal.
- nat gas +13%
- coal -24%
- nuclear +1%
- hydro +15%
- wind +40%
- All solar +167%
linear growth puts the 2026 numbers at
Nat gas 48% (from 32%)
All Solar 39% (from 2%)
Nuclear 22% (from 20%)
Wind 18% (from 6%)
Coal 14% (from 30%)
Hydro 12% (from 7.5%)
but those are not realistic forecast numbers, just a simple extrapolation of a 3 year trend extended out another 9 years.
Still it puts Hydro on the bottom of the list just below Coal. And those will likely be the bottom 2 at some point between now and 2030.
Of course my regional power provider isn't with that plan, National Average is 8% for wind+solar and they only have a token Wind/Solar portion of 3% now. No public plans to take advantage of dropping prices of production, planning to barely let any more solar/wind in on a 9 year plan:
So eventually I'll have to put solar on my own roof because the local power company isn't going to do it for me.
It is impressive that only 3 nuclear sites can do 40% of the electricity here.
I really thought the ELR was going to be something, And with my Dad and my Granddad both having gotten Caddies as their final car I was sure I would do the same. Hopefully, they come out with a car that actually is intriguing in the next 40 years
