So if you are throwing a soirée and need electricity, it’s wise to make sure the…
What is the most important number in clean electricity? It is the carbon intensity per kilowatt-hour (CIPK): the total amount of carbon dioxide, or CO2, in metric tons, emitted by the emitting generators feeding the grid, divided by the total amount of electricity generated, in kilowatt-hours. As you can see in Table 1 on the…
France’s mass transportation system, based on electric-powered urban and national rail—the Paris metro and the Train Grande Vitesse (TGV) being the most spectacular examples—is the model the whole world should emulate. If you’ve never had the pleasure to ride the TGV, it is an amazing experience. The line running from Lyon to Avignon is next…
Toronto runs mostly on uranium and plutonium. Those two nuclear fuels provide the energy that runs Canadian nuclear reactors, which are what make most of the electricity that produces the city’s spectacular nighttime skyline, and makes its elevators, subways, and hospitals work. Uranium and plutonium are extremely clean and efficient generator fuels. They are made…

At around 1:50 in the video, you can see the northwest edge of the storm start to sweep across Lake Ontario. That was Sunday,…
