Brussels Grid Collapses – Solar Batteries No Help

Large parts of Brussels are without power tonight after the City Grid ceased to function at about 10.45pm local time.

But buildings with solar panels on rooftops were not able to maintain their own power supply because the panels are all feeding into to the grid. Even solar panels with battery backup were unable to maintain a supply because EU regulations require a cutoff of the battery supply in the event of a grid outage.

Brussels is home to the HQ of the European Commission – the Berlaymont Building – which has its own petrol powered generators in the basement, so it is still functioning on skeleton power at time of writing.

The health and safety rules were introduced 10 years ago, even though a simple cutoff switch between the grid and the panels or batteries in individual buildings, would solve the problem by removing the threat to power workers as they tried to restore the supply. Lobbyists from the large power companies and grid management companies are responsible for the restrictive regulations.

It is believed the northern part of the EU capital has been affected the worst with the cause still to be identified.Residents have been forced to use candles and have posted pictures of their efforts to restore light on social media.

An earlier power cut is understood to have hit a smaller part of the city earlier in the evening but was ‘resolved by 8.30pm’.

Power firm Sibelga, which handles gas and electricity services in the city, and power network operator Elia have confirmed there is a fault in the grid, with repair teams on site.
Sirens have been heard across the city, which was the victim of a terrorist attack last March.…

The Road to Self-Reliance

American families have been going off-grid for more than forty years, but for most it’s a gradual process, involving a lot of learning by trial and error. In a recent article published in Reason, J.D Tuccille wrote about how his experience going “semi-off-grid” in 2008 led him to reconsider his attachment to the mains, and begin a journey towards self-reliance that is still ongoing today.

Dipping into off-grid waters

In 2008 a power failure lasted a week at J.D’s former home in remote Arizona. While he had his own well, it was controlled by a pump that required electricity, and the surface of the water was too low to dip some out by hand. Then there was the issue of modern plumbing without electricity, and the requirements of coffee pots to consider. However, outages were common – so J.D had come prepared. He and his wife Wendy Wendy had stored water, cut firewood, and fueled up the camping stove and lanterns. They remained hydrated, warm and fed through that and every other experience with the electric grid’s unreliability.
“All in all, it was a bit Little House on the Prairie for our tastes, though with a better wine selection – but ultimately more of an inconvenience than a disaster,” he wrote. “But tolerance for inconvenience can decline with the years.”

When they moved to a new house in the foothills, Wendy had a strict requirement – a climate-controlled environment in the house at all times. This required some research into the best off-grid power systems to use for the climate, so J.D had to get serious.
“This being Arizona, where everything bakes for much of the year under the fireball in the sky, my first thought was solar,” J.D writes. “But I quickly discovered that all of those panels adorning people’s roofs were nothing more than expensive shingles during a power outage. Most solar installations are designed to feed the grid, not keep you independent of it. I priced adding batteries to the mix to gain some autonomy, but they more than doubled the cost. And batteries couldn’t handle the power demands of an air conditioner anyway. So we settled, if that’s the right word, for a 22 kW standby generator, which can handle the well pump and keep the air conditioning running.”

He said they were “especially pleased” with the decision when the European Union completed a coordinated cyber-attack simulation and found it leading to a “very dark scenario,” including crashed power grids.
J.D also beefed up the water storage capabilities at the house with rain barrels hooked to the gutters, which are conveniently located near the garden where he now grows tomatoes, olive and fig trees.

“Wendy and I have stumbled down our path incrementally over the years out of a combination of necessity and curiosity,” he writes. “We also keep tweaking our set-up. In addition …

Be Our Guest: Food Preservation Part I

 

Charcutier Sean Cannon is opening his first restaurant, Nape, in London this month. Born and bred in Norfolk, Sean told the Guardian how growing up in a self-sustaining community influenced his cooking. His best kept secret – preserving.

“Whether it’s killing an animal and having lots of fresh meat, or early summer and everything is ripe, knowing what to do with a glut is key.” Cannon said.

If you live off-grid you’ll know that preserving food for future use is essential. Not only does it provide food security, but also allows you to taste sweet summer berries in the winter. By doing this age old tradition, it also stops more modern thoughts and concerns of “what is actually in my food?” If you do the preparing and the preservation, you know exactly what has gone into the food you will be eating.

There are many ways to preserve food including canning, freezing, dehydrating and smoking.

Canning is a valuable and low-tech way to preserve food. There are two main methods for this, either water bath canning or pressure canning. It is worth noting that water bath canning should only be done for acidic fruits, such as berries and apples. If canning other produce such as meats and vegetables, pressure canning should be used; otherwise there is a high risk of food poisoning.

The basic process is to heat water in your canner (or large pan if water bath canning). This should not be filled to the top; 3-5 inches should be left for your jars of food. Jars should have lids secured and be placed carefully into the canner, being careful not to knock other jars, as they could crack or break under the high temperatures. The jars should be immersed in the canner with the water just covering the lids. The canner lid should be locked in place if pressure canning and the jars left for as long as needed according to the recipe. After the required time, the canner should be allowed to depressurise if using a pressure canner, before the jars are removed. Heat protection and necessary precautions should be taken to ensure you do not burn yourself. The jars should then be left to cool and seal for a minimum of 12 but ideally 24 hours. The sound of popping and pinging will mark your canning success!

Canning is so popular because of the wide variety of foods that can be preserved this way and the length of time they will remain edible for. Plus there’s no worry of keeping food frozen or cool!

Canning does however come with an initial start-up cost. If you’re only looking to preserve fruits and jams, then water bath canning in a large pan is of course an economical way to go. However, if you’re looking to preserve a wider variety of foods which includes meat and vegetables, …

Burt’s Bees Founder’s Cabin

Burt’s Bees founder Burt Shavitz was a modern day Thoreau. He loved nature and lived in a cabin much of his life.  For him, as he said before he died: “the old ways are the best ways” and “the land is everything”.

The company he founded unveiled Mr Shavitz’s  iconic, low-key cabin in January. Sadly, the company moved the rustic cabin from rural Maine to its headquarters on the American Tobacco Campus on in Durham, NC. The cabin displays Burt’s personal artefacts. The 300sq ft converted turkey coop originally had no electricity or running water.

“Burt was a living embodiment of our purpose to connect people to the wisdom, power and beauty of nature. A year after his passing, Burt’s life is a potent reminder for all of us that we can’t lose sight of our relationship with nature”, said Jim Geikie, General Manager of Burt’s Bees.

An observation bee hive was also installed to help educate the 1.5 million annual ATC visitors on bees and their importance to environment and humans. At its seasonal peak, the observation serves as a home to over 15,000 bees and is the largest of its kind in North Carolina.

Geikie spoke of his former boss’s habit of not using any electronics and instead choosing to embrace nature.”Burt used to say ‘I wake up when the sun comes in my window and go to bed when it’s too dark to read…Each day we come to work, we’ll be able to fondly remember the man who didn’t use an alarm clock and applaud his way of life as a beacon of inspiration in our hurried times”, said Geikie.…
