Church In New Orleans Establishes its Own Solar-Powered Electricity Resilience Hub (theguardian.com) 58

Posted by EditorDavid from the seeing-the-light dept.
Back in 2021 Hurricane Ida knocked out power lines in New Orleans, leaving parts of the city in darkness for 10 days.

So a coalition of community-based organizations (including some churches) decided to build "solar-powered disaster response hubs that could transform the city's approach to resilience," reports the Guardian. So far there's seven, but the group "has ambitions to build dozens more." On a bright, balmy autumn morning a couple of weeks ago [61-year-old pastor Antoine] Barriere climbed a long, steep ladder to show me the 460 solar panels that now cover a third or so of his church's flat roof. The solar panels were generating more than enough energy to power Household of Faith, a non-denominational megachurch with 4,000 mostly Black parishioners in New Orleans East. Downstairs, a cabinet was stacked with backup batteries that were fully charged in case of a power outage — a frequent occurrence thanks to the low-lying city's vulnerability to hurricanes, thunderstorms, high winds, extreme heat and flooding. In a worst-case scenario — no sun, thundery dark skies and power outage — the backup batteries could power essential appliances for a couple of days including the water heater, five commercial fridge freezers storing perishables for the weekly food pantry, and air conditioning for the vast main hall which could be converted into a dormitory-style shelter.

But on this brilliant cloudless morning, most of the solar-generated energy was going into the city's electric grid. New Orleans' one-for-one net metering scheme allows the church to offset its excess clean energy against the utility's dirty energy, and this should become a net zero facility within 12 months... The idea is that each community lighthouse should be an institution locals already know and trust — such as a place of worship, health clinic or community centre — that can be converted into a resilience hub where people can converge during a power outage to get cool, recharge phones, have a meal, connect to a medical device or store medication that requires refrigeration such as insulin. In addition, community lighthouses will be able to keep the services running that people rely on such as the food pantry and religious sermons, while also adding capacity to the city's wider emergency-response efforts as a distribution hub, shelter and possibly even house a makeshift clinic.

      I'm reminded of an article that covered some of the aftermath of the 2011 Tohoku tsunami, in that article they pointed out an ancient marker from an earlier tsunami. The marker was a monument to those washed out to sea and as a high water mark warning for future generations. It turns out the 2011 tsunami got no higher than the marker for the last big tsunami that hit the area. Buildings below the marker were destroyed, and those above the marker were not damaged.

      I remember talking to someone that grew up in North Dakota, or if I recall incorrectly it was certainly somewhere in the Midwest USA, and we were talking about flood management. This was because we were experiencing flooding at the time. Where he grew up there was apparently something of a fight about developing an area around a river that ran through a relatively large city (as in relative to the Midwest, not all that big compared to the coasts) where the area was designated off limits from development. The area was off limits because there was a big flood some time ago and to avoid putting future structures and people at risk the area was considered off limits for new construction.

      We are having some of that here, areas deemed off limits because of flooding but fights to develop this property due to proximity to large populations. People naturally settle around water because water provides a cheap and easy means to move people and cargo. This goes double if the water nearby is freshwater since with minimal processing to filter out some bits floating in it this water is suitable to drink. Then there's the opportunity to get the water to do work if it moves fast enough and/or has some minimal drop in elevation over distance. Most any kind of heavy industry likes large bodies of water nearby as the water can be used for all kinds of chemical processes on an industrial scale, as well as provide cooling for (or perhaps heating in some places) for factories and such.

      It will be difficult to move people from the coasts because we use water for so much. Seawater isn't suitable to drink so the attraction over finding water to drink isn't so high, though with enough cheap power available desalination can be cheaper than piping in water from some place else. The sea is great for bringing in large ships, industrial cooling, and people like to go surfing and swimming in the sea (which I guess is kind of cooling on an industrial scale).

      The best we can do is warn people on where the high water mark is for things like hurricanes and tsunami. That doesn't mean we don't build along the coast, but it does mean that if we build on the coast then build in ways that allow for rising water. It looks like around here those that build along the river are slowly adjusting to the idea of flooding being something to be dealt with more wisely. No longer are valued records kept in basements, but they are on the third floor or something. The lower levels are getting converted to parking lots and conference rooms. If a conference room gets flooded then there's a loss of some furniture and A/V gear but that's far less expensive to replace than offices, data servers, and backup generators.

      Oh, right, wasn't there some big deal about flooded backup generators in Japan in 2011? I believe that one mistake created a very large and expensive mess.

        Have you ever visited Hawai'i? It's not uncommon there to see lines painted on the walls and windows of buildings with dates to mark the high-water line of former floods and/or tsunamis. Do people avoid building in the historic flood zones? Of course not; the markers are just there as records, not as warnings.

          People -- or at least the insurers they need to get a mortgage -- absolutely do pay attention to flood maps. There's a big financial difference between building in the 50 year flood zone and in the 5 year flood zone.

          • I'm sure they do. However, these high water marks are from tsunamis, which aren't exactly predictable events. It's rather like the signs you'd see on buildings with bomb damage in London during the Blitz: Business As Usual.

          I'll see marks like those on the walls of businesses that were flooded. One restaurant has a mark painted on one of the large windows in front. They also have photos of the flooded dining room hanging on the walls, and some other things that demonstrate the damage. I remember a park that had marks on a tree to show how high different floods got over the years, some of the marks had to be about 20 feet above the ground.

        It wasn't the flooded generators that doomed Fukushima Daiichi. It was the initial tsunami surge water. They actually had pumps on site in plenty of time to avert a meltdown, but because the control and monitoring systems were damaged and physically inaccessible, almost all of the cooling water that was pumped in was diverted to storage tanks without anybody noticing.

      How is that going to send a giant FU to nature? Instead of leaving, just build hot dipped rebar reinforced concrete pilings 40 feet down and start the house 20’ up from ground level, or higher if necessary. Rate everything to withstand cat 5 hurricane winds and debris with storm shutters even for solar panels and reinforced everything. Get a generator and supplies to last off grid. With construction like that worst case if the ground washes out you just boat in.

    I really don't want to pick on people trying to improve their community, but while solar panels themselves can do surprisingly well in a hurricane that doesn't help much if they're ripped out because they're mounted in a way that allows wind to catch them. Beyond that, battery backups for 'a couple of days'? That is wholly insufficient. Power was out for weeks after Katrina.

    I would say that if you're really looking for disaster support during a similar disaster, what you're really looking for is the ability to safely store a lot of water prior to a predicted event, the ability to filter more water as required, and the ability to store human waste until sewer service can be restored. And it might be nice to have some food and cots, too.

    Pretty much you want a survivalist bunker that can support however many people you want to support for a few weeks. Add a helipad and a deployable floating dock for emergency services to get to you, and you're set.

    But all that is far more expensive and that's the reason there aren't already buildings like that in place and being maintained. Even if you use it as a community centre or something, you're still going to have a lot of trouble paying for it.

    • Beyond that, battery backups for 'a couple of days'? That is wholly insufficient. Power was out for weeks after Katrina.

      So what you're saying is, the batteries are only good to get them through a short power outage, and would have run down before the power was restored after Katrina and that therefore they're a useless waste of money, right? Of course, that's assuming that the sky was constantly overcast during the outage so that there was nothing for the solar panels to use, which may or may not be tru

      A few days of power, plus in-going solar generation, would be very helpful in an emergency. That gives emergency services time to get generators on-site, and continues to supplement them.

      As things like this develop, I can see entire small communities going off grid. It just won't be worth it for them to pay the connection fees, when they can operate a micro grid themselves.

      True, it *might*. But once you move even a little way inland it's not the wind that's killing people. It's the flooding. And in a *huge* hurricane like Katrina it's the aftermath that kills -- the breakdown of systems and the disorderly evacuation. In Katrina, nearly *half* the deaths were from untreated medical conditions like heart disease.
