Unlike Other Power Sources, Wind Turbines Still Useful When They Stop Working

- Adam Clare

Wind turbines produce renewable energy from air with a small footprint on the ground. This means they can get placed in various locations and offshore they can be massive (and therefore more efficient), but when the wind turbines reach the end of service their blades take up a lot space in landfills. Thankfully the blades can be reused to build bridges!

Even when they are no longer useful to produce electricity wind turbines live on in useful ways – another reason to build more turbines.

Originally a metals recycling company, Anmet started exploring ways to repurpose wind blades about seven years ago. Since then, it developed a small commercial business making outdoor furniture out of discarded wind turbine blades. Bridges, Sobczyk says, are the next area it would like to expand into commercially.

The company’s first blade bridge took about three years to test, permit, and build. After harvesting decommissioned blades from a wind farm in Germany, the blades were subjected to a battery of engineering tests in partnership with Poland’s Rzeszów University of Technology before being cut up to create the primary support structures for a pedestrian footbridge. In October, Amnet installed that bridge over a river in Szprotawa, the small town where the company is headquartered.

Insulation is Better Than Oil

Insulation is a boring solution to the deadly consumption of oil inside your home. If you have a gas furnace or other fossil fuel heater then you can start reducing your consumption of the dead dino juice by better insulating your home. You can also go a step further and replace planet-killing heating solutions with a heat pump.

In the United Kingdom a simple policy change to encourage homeowners improve their insulation and/or install heat pumps can eliminate the need for Russian gas. The time to this is right now so it cuts off the market desire for oil from a state waging war on its neighbour.

If you’re a homeowner then improve your insulation and get off of gas.

An analysis by the think tank notes concludes that the deployment of insulation and electric heat pumps in 6.5 million homes by 2027 could reduce UK gas demand by four per cent, which is roughly equivalent to UK imports of Russian gas.

By enabling citizens to use less gas to heat their homes, a policy focused on heat pumps and insulation could also curb energy bills and protect millions of households from volatile international gas prices, it said.

This Book Can Give You Power

- Adam Clare
Solar Panel School

Oil prices are rising again and oil is yet again at the centre of international conflict, it’s time to get off of oil. Sustainable energy is peaceful energy. Solar power is one such renewable energy source that can work anywhere the sun shines. Setting up a solar rig can be a challenge and intimidating for the average person. A freely available book, To Catch The Sun, provides the current knowledge you need to setup solar power generation of any size.

This is a book for people looking to build a better future together, that includes:

  • Inspiring stories: Real life accounts of building solar power in communities.

  • Technical details: Straightforward descriptions of solar components and diagrams of systems, replete with real examples (many from the systems described in the stories).

  • Math and science: Easy-to-follow math that allows readers to size small photovoltaic systems for all types of environments and uses.

Dutch Climate Lawyer Wins Dresden Peace Prize

Yes, a lawyer won a peace prize. Roger Cox, a Dutch climate lawyer who took on Shell, has been awarded the 2022 Dresden Peace Prize for winning a case that inspired similar cases around the world. On behalf of Friends of the Earth, Cox won a ruling in a Dutch court against Shell last year (the case itself was launched in 2015) which forces the company to reduce its carbon output by 45% by 2030. The non-renewable energy company is based in the Netherlands making it subject to Dutch courts.

Climate activists hailed the decision as a victory for the planet that built on a 2015 case Cox brought requiring the Netherlands’ government to cut emissions at least 25 per cent by the end of 2020 from benchmark 1990 levels.
Since then, similar cases have been brought against governments and corporations around the world, with mixed results.
“Peace is more than the absence of war,” the organisers of the Dresden Prize said. “Standing up for peace in times of climate crisis means acting responsibly and fighting for a humane and thus peaceful life for future generations.”

Beer Cans for Passive Heating

- Adam Clare

They aren’t just for transporting a yummy beverage, beer cans can be used to create passive heating too. A simple contraption that you can make in your spare time can save you heating costs and help reduce your carbon footprint. A beer can heating system, like the one in the video above, is just a series of cans in a row painted black out in the sun under a casing. The dark cans heat up from the sun and move air through them using basic convection.

A DIY beer can heating system is perfect for a shed, garage, or even using it augment your home’s existing heating system.

The concept is relatively simple. The aluminum cans have both of their ends cut off and are fashioned into a series of long metal tubes, painted black. With a fan at one end, and some fins cut into the tubes slowing down the airflow, the metal is positioned in a way to get heated by the sun as the warm air is pulled into the building.

Thirteen years later, the same old beer cans are still chugging along, helping keep the space warm and heating bills low – about $300 annually, McLauchlin estimates.

“It’s -22 C right now and my furnace didn’t come on today,” he said over the phone in early December.
