Our paper now avail­able from the Pro­ceed­ings of the Nation­al Acad­e­my of Sciences:

Pre­vi­ous analy­ses have found that the most fea­si­ble route to a low-car­bon ener­gy future is one that adopts a diverse port­fo­lio of tech­nolo­gies. In con­trast, Jacob­son et al. (2015) con­sid­er whether the future pri­ma­ry ener­gy sources for the Unit­ed States could be nar­rowed to almost exclu­sive­ly wind, solar, and hydro­elec­tric pow­er and sug­gest that this can be done at “low-cost” in a way that sup­plies all pow­er with a prob­a­bil­i­ty of loss of load “that exceeds elec­tric-util­i­ty-indus­try stan­dards for reli­a­bil­i­ty”. We find that their analy­sis involves errors, inap­pro­pri­ate meth­ods, and implau­si­ble assump­tions. Their study does not pro­vide cred­i­ble evi­dence for reject­ing the con­clu­sions of pre­vi­ous analy­ses that point to the ben­e­fits of con­sid­er­ing a broad port­fo­lio of ener­gy sys­tem options. A pol­i­cy pre­scrip­tion that over­promis­es on the ben­e­fits of rely­ing on a nar­row­er port­fo­lio of tech­nolo­gies options could be coun­ter­pro­duc­tive, seri­ous­ly imped­ing the move to a cost effec­tive decar­bonized ener­gy system.
