Joe Biden's Solar Plan and the Prescience of Jimmy Carter [View all]
The Biden Administrations announcement on Wednesday of a plan that could set the country on a course to generate forty-five per cent of its electricity from solar panels by mid-century mightmightsomeday be remembered as one of those moments that mattered. Thats because it sets a physical target whose progress will be relatively easy to measureits the energy equivalent of announcing that before this decade is out we will achieve the goal of landing a man on the moon and returning him safely to earth. This plan is much more ambitious, though: the Apollo project focussed all the nations technological might on moving one person; this is more akin to landing all of us somewhere very new. But physical targets are easier to track and understand than, say, the squishy and amorphous chatter about net zero emissions and so forth. Observers will be able to track with ease our progress and see if future Administrations are keeping up the pace.
By itself, of course, converting one countrys electricity system to run nearly half on solar is not going to curtail global warming. But an effort at this scale will move us fast along the learning curve: the cost of solar has regularly fallen about thirty per cent with each doubling of capacityso increasing its scale from less than four per cent, which it is at present, to forty-five per cent should make what is already the cheapest energy on Earth far cheaper still.
There are plenty of pitfalls. For one, a target is only as good as the money behind it; Congress needs to step up and start appropriating, and the $3.5-trillion budget plan could be the first down payment on that task. (A task made much more difficult by news that much of corporate America is throwing down hard to stop parts of it.) And the political problems only start there: siting solar farms often kicks up local opposition from people who dont want to look at them. Even in green Vermont, where I live, this is a budding problem.
And there are deep questions about whether weve even got the metals and other materials left to make it happenin a recent paper, Megan K. Seibert and William E. Rees argue that proponents have failed to address questions such as how gigatons of already severely depleted metals and minerals essential to building so-called RE technologies will be available in perpetuity. The London-based Carbon Tracker Initiative, however, has recently made a case that material constraints will steadily become less of an issue; for the moment, the regularly falling cost of solar seems to make their case. And, as Saul Griffith, the author of the forthcoming book Electrify, says, using renewables requires far less in the way of materials than a fossil-fuel-based energy system.
