Toronto, Ontario may lead the world towards a future where 100% renewable energy is proven viable. Newly announced biogas facilities will provide the equivalent of 100 megawatts of renewable energy.
Detail
Who said renewable energy can't be built quickly, to make a profit, reducing carbon emissions, while not being intermittent like solar and wind? Bio-gas is the perfect way to turn sewage and bio-waste into a clean renewable fuel that is dispatch-able in the same way as fossil fuels. When we combine solar, wind, biogas, hydro and geothermal we create a world that works on local renewable energy that creates a sustainable economy and a sustainable environment. 100% renewable energy changes everything. Think about it. We all can do this.
