Given the fact that annual CO2 emissions from fossil fuel combustion surpassed 37 billion tons in 2019, the net-zero goal by 2050 will call for an energy transition unprecedented in both pace and scale. A closer look at…

In the “energy is a necessary evil” frame, we look at our current electricity needs and then ask, “How can we generate all that from zero-carbon sources?” In the alternate framing, you say that to the extent we can develop affordable, zero-carbon sources of electricity, we want to generate tons and tons of electricity. Ideally, we would want to rep... See more

Even though the supply of new renewables (wind, solar, new biofuels) rose impressively, about 50-fold, during the first 20 years of the 21st century, the world’s dependence on fossil carbon declined only marginally, from 87 percent to 85 percent of the total supply, and most of that small relative decline was attributable to expanded hydroelectrici
