renewable-energy / Green Building & Sustainable Home Renovation Information & Advice

One of the biggest drawbacks to renewable energies like wind and solar, is that it is unpredictable. This presents a challenge to grid operators, as they struggle to meet demand while compensating for calm winds or clouds. One method of balancing supply and demand that is garnering some attention lately, is pumped stor...

Recent articles have praised major public investments in biomethanization plants around Canada and North America. These huge chemical plants produce renewable natural gas (RNG) which is a pipeline-quality gas that is fully interchangeable with conventional natural gas and so can also be used in natural gas vehicles. RN...

What is the cleanest energy?  Despite how commonly  the term ‘clean energy’ is used, there is actually no such thing. At least not in the power delivery market; there are only various levels of ‘dirty’ energy. Starting with the worst and moving up, that would in general be - coal, oil, natural gas and propane, wood and...

New technology combines solar power generation & battery free power storage The forever-changing landscape of the green home building industry sees ideas come and go, and on occasion a game-changing technology or product emerges. The big news lately is in renewable energy - solar power generation, solar power stora...

Home Energy Generation, which option is best? How the electrical grid is fed near you will be a huge factor in determining the carbon footprint of your home, with or without your own renewable power generation such as having solar panels on your roof. If you live near a windfarm, that's where most of your power comes f...

Mitigating climate change at home, get on your bike! As we look for ways to mitigate climate change, improving home energy efficiency and decentralising power generation is something we can do to reduce our personal energy consumption and carbon footprint. Theoretically then moving towards home solar, wind power and ev...

Updated: Aquion as a saltwater battery is no longer available in North America having moved to China after being bought out. But we've heard about a Dutch company who are starting to commercialize something similar - subscribe to the EcoHome newsletter here and be the first to find out when salt water batteries are ava...

When considering solar cells as thin as laminate and completely transparent, the possibilities seem endless. Imagine every glass or laminant surface in our built environment and all of our devices, large and small, harvesting solar energy. In a world of passive, self-sustaining mini-power stations, would the need for f...

The idea behind the Epiphany onE Puck is simple: use a Stirling engine powered by heat disparities (a hot or cold drink, a candle, ice, etc.) to fully charge your cell phone. Invented in the early 1800s, Stirling engines are far from new. However, with new materials and modern electronics they are now being put to use ...

There is a lot you can do in home construction to take advantage of the free energy provided by the sun. That can be passive solar, which is about home orientation and window design to passively heat your home, or active solar which involves mechanical solar panel systems. Solar panels can be either thermal (which tran...

Bullfrog’s green electricity comes exclusively from wind and hydro facilities that have been certified as low impact by Environment Canada under its EcoLogoM program. Their natural gas is presently sourced in Quebec by collecting methane escaping from a landfill site. A common question seems to be "How do they ensure t...
