Cardel Homes is introducing a unique upgrade for 50 newly-built
homes in 2018:

100% green electricity! In addition to purchasing an energy-efficient property, you’ll have the comfort of knowing that, for the first year, your home will be bullfrogpowered with 100% clean, renewable electricity – all courtesy of Cardel Homes.

As a homeowner, you’ll pay the cost for conventional electricity, as provided by your utility of choice, and through our partnership, Bullfrog Power’s generators will put renewable electricity onto the grid to match the amount of power consumed in your home. In having a home that is bullfrogpowered with 100% green electricity, it will reduce your carbon emissions footprint by more than 1 tonne per year!

How it works.

When you choose green electricity with Bullfrog Power, you make sure that for every kWh of electricity you purchase, a kWh from a pollution-free, renewable source is produced and put on the grid on your behalf. When Canadians choose renewable electricity, we reduce the collective demand on fossil fuel-based generation. In purchasing this home and supporting green power, you are helping to green Canada’s energy system, and create a low-carbon future!


We’re putting green energy on the grid for your home at no cost to you.


We’re reducing the emissions of your home by more than 1 tonne.


We’re supporting the growth of green energy projects in Canada.
