Clean Energy Revolution Is Ahead of Schedule
You see, the two trends reinforce each other. Cheaper batteries mean that cars can switch from gasoline to the electrical grid. But currently, much of the grid is powered by coal. With cheap solar replacing coal at a rapid clip, that will be less and less of an issue. As for solar, its main drawback is intermittency. But with battery costs dropping, innovative manufacturers such as Tesla will be able to make cheap batteries for home electricity use, allowing solar power to run your house 24 hours a day, 365 days a year.
So instead of thinking of solar and batteries as two independent things, we should think of them as one single unified technology package. Solar-plus-batteries is set to begin a dramatic transformation of human civilization. The transformation has already begun, but will really pick up steam during the next decade. That is great news, because cheap energy powers our economy, and because clean energy will help stop climate change.
Of course, opponents of the renewable revolution continue to downplay these remarkable developments. The takeoff of solar-plus-batteries has only begun to ramp up the exponential curve, and market shares are still small. But it has begun, and it doesn’t look like we’re going back.
