SUZNV + 1,197 February 16, 2021 (edited) In place that crowded and the price of the houses are high, or where the electricity price is high, then investing in insulation make sense. In Texas such as Houston the house price and electricity price is quite cheap and so the insulation cost especially double glazing windows may not worth the investment (the windows will need to change every 15 years anyway). In cities that houses are expensive then the one who could afford them will not worry about electricity bills or why should landlords need to worry about tenants energy bill. US electricity price is 11 cent per kilowatt-hour while in the EU it is about 26 cent kwh and US people are living more spreading out even in metropolitans.

Do you double the cost of your networks to prevent 1 day blackout in 10 years? You do what you have to do to save lives in very cold areas or very hot areas with a concentration of vulnerable people like those who died in a very hot summer in NYC years ago. It may involve education in how to use various methods to keep cool or places to shelter. It could involve cooling or warming areas in highly populated areas. Telling people how to cool down in a tub or with wet towels, warm up with heating pads. Senile people often forget to do sensible things that could save their lives. Community calling checkups on vulnerable people. Emergency numbers for people to call. Large heaters or air conditioners to heat or cool available indoor spaces. Emergency generator and water trucks. Distributed energy and localized energy should be big topics discussed rationally as just as important as any other topic having to do with catastrophes of all kinds from weather to war. Our military has a lot of personnel and equipment that can be used in civilian catastrophes and it is good real world training for them. We should also be planning for a electro-magnetic pulse attack. https://www.dhs.gov/news/2020/09/03/dhs-combats-potential-electromagnetic-pulse-emp-attack 1 2 Quote Share this post Link to post Share on other sites

They live in Trailer parks or Mobile Home estates from the 80's. Many here in Ft. Stockton live in very old plastered "stucco" houses. My guess is 100+ lost their lives due to the cold and crappy power grid. Still no power here, and not expected till tonight. A lot of those fifties and sixties stucco homes had very little insulation in California, but nobody was going to freeze to death. They were tar paper covered with chicken wire, stucco, and paint. Now they sell for half a million dollars. Hopefully they have had an insulation upgrade. 2 1 2 2 Quote Share this post Link to post Share on other sites

A surge of renewables onto a grid without sufficient rotating mass could cause serious problems: power being cut in certain areas in an effort to bring demand back in line with supply; and large power plants getting disconnected from the grid to prevent them becoming overloaded. The key to understanding this is frequency i.e. the speed of the grid. Some parts of the world such as the U.S. operate at a frequency of 60 Hz. Other parts operate at 50 Hz. Taking a simplified view of things, this is a measure of how fast electrons are moving along an alternating current wire. 60 times a second (60 Hz) or fifty times a second (50 Hz) is the frequency of the grid. If it rises too much above or below that, trouble results. 1 1 Quote Share this post Link to post Share on other sites

This issue starts from someone making a point about going into a 'cooling cycle'. We are which is 11 years (yes I know there are other much longer cycles) We are heading into the solar minimum in this short cycle and in about 6 years we will be at the solar maximum. The final point on this is this cycle is completely irrelevant to the GW debate. Quote Share this post Link to post Share on other sites

The final point on this is this cycle is completely irrelevant to the GW debate. ahh speaking of load stuff shall we continue? You can also get a domino effect. If frequency goes out of control, one part of the system has to shut down. This causes severe strain on the rest of the network. If not dealt with, cascading outages lead to a major blackout such as that experienced in the Northeast of the U.S. in 2003. 60 million people ended up without electricity. In the summer of 2019, major blackouts in New York City and the U.K. further emphasize the need for greater grid resilience. Quote Share this post Link to post Share on other sites

Wind Mill pump seems the most direct energy converting. Can a wind mill do that in windy place like Scotland? The pumped storage efficincy is simply input v output. Who cares where you get the "juice" from for pump-mode? In my experience, it was time shifting Nuc power, then "selling water" on the way out. 1 Quote Share this post Link to post Share on other sites

If it rises too much above or below that, trouble results. With the advent of both power electronics and DFIG's , you can extract MUCH more stored rotating inertia from a wind turbine than a synchronous connected steam turbine. The steam turbine-generator stores a whole lot, but can only extract about 5% of it without tripping underfrequency relaying. With a wind machine as featured, you can get about 90% (+/-). 1 Quote Share this post Link to post Share on other sites

You could get a 1000 gallon "pig" or 1500 gallon one like the farmers use on the corn dryers and fill early spring when is at it lowest. Not sure how much propane is running in bulk, but say even 1.29 a gallon...... figure on a gallon an hour on 15k watt genset. Still fairly expensive electricity. NG gensets are less to operate but to run as full time buying power from your local electric company is probably 6cents a kilowatt? Hard to beat that.

I have a air-cooled nat gas fueled recip (auto-start,auto transfer) as I live in a HIGHLY rural area with a major nat gas pipeline nearby, tapped for local supply. Utilities call my area "ranch power" (ie, at the end of a distant, convoluted distribution system) with frequent outages (forced and planned), with a private well and septic system. It's bad to loose heat, but loosing water is worse. Anyhow, efficiency is abysmal...and performance is degraded residing at 7400'. Covenants on my property do not permit propane.
