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...

Hydroelectric power generation is definitely renewable but not always 'green' when you consider all the side effects, especially when it comes to large hydroelectric dams. In the quest to find alternative power sources to replace fossil fuels, the energy that can be harnessed from moving water is leading to some impres...

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...

The Zoetrope is a vertical-axis wind turbine made from common materials. Many of the materials can be found at your local hardware store and the rest can purchased online or made at home, for the truly industrious amongst us.  The Zoetrope was conceived when renewable energy advocate, Mike Marohn commissioned Applied S...

Housing is an enormous source of carbon emissions, so it is also a place where we have tremendous room for improvement. This building guide will walk you through the steps than can help you minimize your personal emissions as much as possible, whether you are building, buying or renting. Keep in mind, this is not a sac...

Countless inventors are stepping up to the plate with the latest and greatest green technologies that will save the planet. This is great to see, but the waters of sensible change will no doubt be muddied along the way by some failed attempts, some questionable claims, and perhaps even a little snake oil!  We found the...

We've seen portable charging devices for personal gadgets, we've seen vertical axis wind turbines and now we have seen a marriage of the two. That's right, appropriate technology enthusiasts, there is a portable wind turbine on the horizon and it's perfect for charging your electronic gizmos.  Skajaquoda is a research ...

The continuing drop in cost for home solar power generation has led to a dramatic increase in the rate of installations, for both residential and commercial use. Increasing the yield through reflection could make that an even more affordable energy supply option. Most of the advances in solar power production come from...

A project started in 2002 by Verdant Power Inc. saw tidal turbines placed 10 metres deep in the East River of New York, taking advantage of the reliable tidal surge of Long Island Sound.  Spinning silently at 35-40 rpms for 18 hours a day in a 4 knot current, tidal turbines eliminate two of the more common complaints a...

Standard solar panels are rigid, relatively heavy and fragile. A new product on the market called Microsystems Enabled Photovoltaics (MEPV) from mPower Technology may change that. The cells in these pliable sheets are made from high-efficiency silicon, and if one cell is damaged or loses power, the rest will continue t...

A typical washing machine can use up to 87 litres of water per load, not to mention its ability to eat up electricity. An efficient Energy Star machine can cut water usage to about 49 litres per load and significantly cut energy usage, but this, the Drumi, will not only wash your clothes without using electricty, it al...
