Please explain how Bullfrog has built a parallel power grid and how you receive 100% renewable energy?
Google it.

You are not personally receiving renewable energy. PERIOD. Electricity is electricity once it's in the grid, and there is no special "channel" they switch on for houses that want renewable or nuclear power or coal power. You get what you get. PERIOD.
What you ARE paying for is essentially a carbon offset, except that your carbon offset goes exclusively to Bullfrog who has invested in certain wind projects. A "regular" carbon offset goes into a group fund (think of it like a group carbon RRSP) and that fund then invests into dozens of renewable programmes in Canada (even some of the one's Bullfrog is invested in). These are "VER+ rated" for Canadian projects. Or you can go Gold rated, which invests into non-Kyoto countries..the idea being that by doing so it will make a more drastic help to the climate in these "eco-dirty" countries than in a more eco-friendly country like Canada. Like your Bullfrog energy, these carbon offsets are also EcoLogo rated and audited. These carbon offsets are also endorsed by the David Suzuki Foundation if you care about such things.
I'm not saying there's anything wrong with it, but you're delusional if you think you're getting renewable energy to your house. You are getting mainly nuclear and hydro and paying the carbon offset for your house's carbon footprint to Bullfrog.
I only know this much about the topic because IQ and I have been driving carbon neutral cars for the last few years because of carbon offsets. Odd that this comes up, since I was just talking about this with a respected forum member about having my doubts about renewing my carbon offsets for our cars this year. He says "do it", but I'm still on the fence. I'm cynical if it's actually doing anything.
BTW Smart Electric, doesn't it suck that my Porsche 911 is just as carbon neutral (if not moreso) than your electric car??
