240 percent: this is the increase in battery storage capacity added in the United States during the third quarter of this year, compared with the second quarter. 240 percent is certainly an impressive figure—the result of research by Wood Mackenzie and the U.S. Energy Storage Association. What’s more impressive, however, is that this may just be the start of a long-term trend—a much-needed trend for a world that is hoping to someday rely on solar and wind for most of its electricity. Intermittency is the biggest obstacle for solar and wind replacing fossil fuels and nuclear entirely. The sun simply does not shine around the clock—or the year—and the wind does not blow all the time. To make up for this—and to store excess electricity produced during peak sunshine and wind—battery storage has been touted as the simplest and most effective solution. Even though it is not particularly cheap, […]
