Nuclear powers Toronto, cheaply and with no carbon

Another great read by Steve Aplin: Nuclear powers Toronto, cheaply and with no carbon: "Yesterday I pointed out that nearly a quarter of Toronto’s 24.7-billion-kWh-per-year demand for electricity comes from the Toronto Transit Commission (TTC), the company that runs the city’s subways, streetcars, and buses. And more than three-quarters of the TTC’s electricity, a whopping 4.4 billion kWh, is used to move electric-powered subways and streetcars. Where does that electricity come from?
Mostly from nuclear plants. Table 1 on the left-hand sidebar gives the sources feeding the Ontario grid in the last hour. As you can see, nuclear is by far the biggest single electricity provider; it usually out-performs all the other sources—hydro, gas, coal, wind, “other” (mostly biomass but some fossil)—combined. And as you can also see, nuclear comes with no emissions of carbon dioxide (CO2), the main manmade greenhouse gas.
When you get on the TTC subway, you pay $3 if you’re an adult, $2 if you’re a senior or student, and 75 cents if you’re a child. That small amount of money will carry you out to or within easy striking distance of pretty much anywhere in the city."
