Denmark’s Sustainable Energy Programs Inspiring Transitions Around the World

Denmark’s transition to renewable energy is an inspiration to countries around the world, looking to implement their own sustainable programs to decrease reliance on fossil fuels. With more than 45 per cent of Denmark’s total electricity powered by wind in 2016, and an entirely self-sustainable island off the country’s coast, the stage is set for Denmark to continue on its path to eliminate the need for other sources of energy.

Proposal from Tesla Encourages Discussion About Renewable Energy in Australia

Finally, the Australian government is considering the potential benefits of addressing the country’s energy crisis with solar batteries – thanks to a $33 million bet with billionaire tech entrepreneur Elon Musk. In the past, Prime Minister Malcolm Turnbill said a “rush” to increase Australia’s generation of renewable energy would result in more expensive, less reliable power. Following a proposal from Tesla’s Elon Musk, Turnbill is changing his tune, even tweeting […]

Peer-to-Peer Energy Market Emerging as a Reality for Australia

With the rise in popularity of renewable energy alternatives, more and more households are becoming energy “prosumers” – meaning they are both consuming and producing energy. Start-up companies are beginning to tap into this market, creating platforms that allow these prosumers to sell their excess energy to other consumers in the area. Peer-to-peer energy markets are popping up around the world, with start-ups in the United States, Europe, New Zealand, […]

Free Geothermal Power from Earth’s Heart

I have yet to get my mind around the idea that Earth’s inner core is dense iron and nickel, surrounded by boiling liquid like the stuff that comes out of volcanos. Nevertheless I find the potential power of it awesome, although it does remind me how transient life is on earth. The ancient Greeks were not far off when they believed everything – including you and me – is a […]

The Endlessly Renewable Power of the Tides

The water flows high up the beach when the moon is directly overhead, as happens on the far side of planet. The rhythm is predictable with a spacing of approximately 12 hours and 25 minutes. Half way between these points, the water level is at its lowest. There are subtle variations because of local factors. However, the power is always there. This knowledge is not new. In approximately 150BC the […]

PV technologies: Is there a Buyer’s Advantage?

Solar cells have come a long way from being in the realm of NASA, far beyond the pocketbook of most mortals to an ever cheaper commodity that is quickly becoming a mainstream source of electricity. Throughout the history of photovoltaics (PV) different technologies have been competing for the favors of the market, touting their respective advantages. The main two classes competing for the market today are crystalline silicon and thin […]

What is an Earthship?

What is an Earthship? The name itself is a source of puzzlement and wonder to some readers. Some might even think that it’s a vessel where only a chosen people can go to when the world is going under. Here’s the truth though. Anyone can go to an Earthship. But what is it anyway? An Earthship is actually a place where people can live. The place is applying sustainable practices […]

Storing Heat Underground in a Geosolar System

As an engineer and permaculture designer living in a cold-climate, I am particularly fascinated with the interplay between thermodynamics and design and with capturing “waste” energy and finding novel, inexpensive and efficient ways to store and/or recapture and re-use it. One of these such systems, is geothermal storage. In late 2015, our consulting company, Adaptive Habitat, was hired to design and install a geosolar heat collection system just north of […]

Making Biogas is Easy

Methane is a versatile, sustainable gas that can be used to perform everyday tasks like heating water and cooking food with surprising simplicity. Unfortunately producing it and using it at home may seem messy, but below we have a simple DIY instruction on making a biogas digester. All grazing animals have bacteria that are needed for creating methane in their guts, with cows being the most efficient creators of the […]

How to Heat and Cool Your Home Without Electricity

Electricity carried through an immense web of copper eventually makes its way into our homes, providing the endless supply we need for temperature control. It’s expensive, and in some places the air conditioning can easily account for half the electricity bill. Paying this upkeep could even make the difference between life and death in extreme climates. Thankfully, there are other options out there. Using alternative building techniques, houses can be designed that passively heat and cool themselves all year long – without electricity!

How to get a Hot Shower out of your Compost

How to get a Hot Shower out of your Compost

Anyone that has been invested in permaculture or who is beginning to broaden their horizon on the topic will know that bacteria are to be revered. For example, nitrifying bacteria break down ammonia and provide us with healthy aquaponic systems while anaerobic bacteria can provide us with hot showers, yes, nice hot showers, as well as rich compost. Compost heaps can provide hot water for showers for up to 10 […]
