  1. Ruggles will be big . Surf was 30-40% more focused in that deeper water spot w Paulette as opposed to first beach . Second beach was mostly blocked as it has poor SE exposure .Some faces were a solid 12 feet. 
     
    Is Teddy’s wind field of 34 knot winds similar size on east side as Paulette 
    currently i see forecasts of 6 feet @17 seconds from 148-150 degrees Late Sunday / Monday in RI
    I will give a shameless plug of my friends local surf forecasting app. Ww3 data, gfs wind, local cams, and very good spectral analysis from the local buoys. RI specific, but worth checking out: called "HopeWaves" .49be36ddf483d48114800111d22701ae.jpg415fd3545eb37dc373d85ccc8d8fa1b1.jpg

  2. Yeah that’s why I laugh as well... what’s the true impact?  Suburban lawns went brown?
    I still laugh at a Ginxy comment from a while back saying something along the lines of “Have you ever heard of an invention called a hose?”
    I haven’t heard one person mention the drought anywhere outside this forum.  My parents in Woodstock had a fine garden...said the lawn was hurting but shocker, they watered the garden and got a lot of produce during one of the most severe droughts ever in NCT.
    Our town was on a full outside watering ban for most of the summer. Not supposed to water garden or anything. Many did not adhere to it, but the town threatened to cut off service to offenders.

  3. It's a nice idea, but I can't help but wonder what the energy cost is of mining, refining, packaging, shipping, installing and disposing of a gigantic battery. How much solar would you need to be reap to offset both your personal usage and all the fossil fuels spent to produce and dispose of it? I don't know the answer, but I suspect the payback period would be substantial.

    1. ( to the post you are relying to) Energy losses at transmission voltages are not a huge driver for decentralization. The largest benefits are usually sub station upgrade deferrals and other capex/ demand (kW) driven reasons  

     

     2. The full life emmisions impacts of solar, wind, BESS are substantially lower than fossil fuel plants... . For example, solar is around 40 g/kWh( ~4x worse than wind but small scale wind has crap capacity factors so not applicable for a homeowner) over the life of a system and batteries are probably 100,000 g/kwh capacity. If you have a 10 kWh battery and use it every day for 10 years, that's around another 25 g/kWh.

    Thia puts you around 65 total g/kWh which compares favorably to ~400 for nat gas and ~ 800 plus for coal. These are pretty conservative estimates, but does compare favorably to the grid in most places (maybe not wind rich places).

     

    There are some concerns like cobalt mining practices for lithium ion batteries, however those are already being designed around...

  4. Not sure you want to say "cognitive dissonance" or stick to your numbers.

     

    Just like the AGW discussion itself, when you ignore the bluster at both extremes, there certainly is very intriguing and pragmatic discussion regarding the details and science/engineering. Carbon emmisions are dependent on economic growth, climate, energy mix, and regional policy and market structure making signals noisy and solutions ever evolving.

     

    The actual carbon emmisions for 2018 (latest full year data) were down 4.5% year over year, with preliminary data from h1 2019 down even more significantly. There was a notable plateau and period of growing pains in the mid 20-teens, however that seems to have been broken. Nevertheless, Germany has fallen behind 2030 goals. Germany and the plateau is certianly something worth studying ( effects of nuclear decommissioning, effective pricing signals and technology mixtures, etc), but does not show the futility of renewables (see overall carbon) and does not strictly translate to different regions and markets.

     

    I am sure we in the US might face our own growing pains, however they will most likely be different and to this point they have not been too bad. Our experience in the us has been different till this point. Additionally, renewables are actually driving prices down in markets Yes, in areas with less favorable renewable resources we will need to have the storage and transmission discussion, but at much higher penetrations than most of the US has currently. Hopefully these discussions can be done in good faith and grounded in reality. As I said, the markets in the US have been pretty effective at taking coals plants off line to this point.

     

    That is enough typing on my phone for a year and certianly this thread so I will respectfully bow out, but I think there are a lot more pragmatic and smart people out there in the world that you aren't giving enough credit.

  5. I work in/very closely with that industry and that is not really close to the current state of the industry.

     

    Sure PTC, etc can factor in how projects in emerging areas like off-shore pencil, however if you look at the actual current PPA prices I would hope you would evolve your perspective. Hint, onshore wind is relatively steady around 20 $/MWh with combined cycle gas close to twice that and coal >3X. The notion that these projects are some financial burden (even without including externalities) is blind to the industry and the future. Yes, the non-dispatchable nature of renewables factors in and some of the higher penetration middle and end game discussions are open, but considering what's currently going on pricing wise and the emergence of lithium ion, renewables are and should be in the mix.

     

    If you want to talk misinvestment, maybe look at all the policy efforts in place to prop up coal plants that have no future. Coal plants that are already built are being priced out of relevance...

  6. Stowe has always been the more upscale and expensive option, Vail did nothing really to change that. As PF has said, they ( a long with most of the industry) has trended to lower price but higher volumes of season passes and really tries to push people in that direction. Sugarbush IMO seemed to have put some pressure on the other resorts in the area in this regard before Vail purchased Stowe, but the Vail had been moving in that direction anyway.

     

    They make less money on the people who ski a lot, but more on the people that only ski a few weekends/and travel out west and who are now tempted towards passes.

  7. Driving back from skiing... 24 and snowing pretty hard in central VT has given way to 44 and partly cloudy in Manchester, NH. The transition is crazy.
