Industrial Heat Recovery

Industrial Heat Recovery

The pressure, heat, speed and chemical reactions required to transform resources and materials into products requires enormous sums of energy.  The energy intensity of these industrial facilities dwarfs that of even the tallest skyscrapers.  A by-product, and in most cases also an input, of these …

Form and Photons

In an earlier post I discuss the method for assessing the total amount of cloud cover across the Metro Vancouver region.  However, this is only one of three major factors that determine the sunlight available to produce usable energy from your rooftop.  The other two …

Residential buildings across Metro Vancouver account for approximately 30% of energy use.  This energy is split mainly between natural gas and electricity, but since BC’s electricity tends to come from low-emitting hydropower, natural gas actually contributes to just under half of the region’s greenhouse gas …

The Power of Poop

Agriculture contributes up to 30% of all global greenhouse gas emission.  Livestock, whose manure releases methane to the atmosphere, are largely responsible for the bulk of these emissions.  While methane’s lifetime in the atmosphere is much more short-lived than carbon dioxide (CO2), pound-for-pound over 100 …

Energy from the Forests

Energy from the Forests

Trees grow by using the sun’s energy to absorb carbon dioxide from the atmosphere, producing organic material also referred to as biomass.  This biomass can be transformed into useable energy through a variety of processes including combustion, which turns biomass into heat.  Through the combustion …

Wind Resources Across Metro Vancouver

Wind Resources Across Metro Vancouver

Wind turbines provide some of the most iconic imagery when it to comes to renewable energy.  The colour, shape and movement of wind turbines provide visceral symbols of a low carbon future.  Wind energy technologies are also often a low-cost option for energy generation and …

Metro Vancouver Cloud Cover

Metro Vancouver Cloud Cover

The atmosphere has a major effect on how much energy/light/radiation ultimately reaches a solar panel. Specifically, cloud cover and aerosols are the two basic atmospheric constituents that alter the sun’s energy, and while they were initially included in our assessment of solar energy, we did …
