    Sounded like a freightliner just came through, shook the house and trashcans all knocked over. Impressively abrupt here. Weather station has only been up since xmas, but just hit its max gust of 32. Nothing crazy but decent considering it is pretty sheltered from the north by the house and reads low as a result.

    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

    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.

    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...
