Using California’s rooftops, parking lots, and other developed land, the state could power itself up to five times over.<\/p>\n

\n

Solar plants keep getting bigger: The new Topaz Solar Farm, in a remote part of southern California, sprawls over an area about a third of the size of Manhattan. In February, another solar farm of roughly the same size\u2014with 9 million solar panels\u2014opened in the Mojave Desert. Later this year, an even larger project will open in Antelope Valley.<\/p>\n

Together, the three new projects will provide enough power for over half a million homes. But there’s a downside: They’re all in former open spaces that once provided habitat for wildlife, and because they’re in remote areas, some of the energy they produce gets lost along the way to consumers. A new study<\/a> in Nature Climate Change<\/em> says that plants like these actually aren’t necessary: We can get more than enough solar power by building in cities instead.<\/p>\n

The study looks at California, because the state is aggressively increasing renewable energy, and finds that by using land that’s already developed, like rooftops and parking lots, solar power could provide the state with three to five times as much energy as it uses.<\/p>\n

\u00ab\u00a0I questioned whether we have a constraint on land,\u00a0\u00bb says researcher Rebecca Hernandez<\/a>. \u00ab\u00a0It was striking to me that there seemed to be sort of this mismatch of available places to put solar. I wanted to really understand how much land do we have, how much land is available, all these land dynamics that really were not quantified before, and sort of paint a better picture.\u00a0\u00bb<\/p>\n

The study maps out developed areas that are best suited for either photovoltaic panels or concentrated solar power (CSP). California has an area about the size of Massachusetts that is well-suited for PV panels, and an area about the size of Delaware that is a good match for CSP. If these spaces were fully plastered with solar tech, they could provide over 20,000 terawatt-hours of power every year.<\/p>\n

By building in and near cities, we could also add new solar power more quickly, because remote plants require new transmission lines. \u00ab\u00a0We have to build out infrastructure to catch up to these places,\u00a0\u00bb Hernandez says. \u00ab\u00a0Really, our solar energy installations are now dictating the infrastructure of our grid, which is sort of backwards.\u00a0\u00bb<\/p>\n

Remote solar farms also lose power as it is transmitted over long distances, so it’s not as efficient. \u00ab\u00a0There’s two problems with solar energy,\u00a0\u00bb Hernandez says. \u00ab\u00a0One is that we need to deploy it rapidly, and two we need to do it efficiently. We’re on track to meet our renewable energy goals, but is it fast enough? Many of us would probably argue it’s not, because we’re running behind climate change. The truth is that California’s not being effective.\u00a0\u00bb<\/p>\n

As the sprawling solar plants are built, they not only alter habitat for wildlife, but also cause carbon emissions as soil is disturbed. \u00ab\u00a0We don’t really know what the impact is in places like arid lands,\u00a0\u00bb she says. \u00ab\u00a0Our understanding of soil carbon cycling in these areas is very shallow. There are studies being done now to address the question, and the fact that it is a question should make us pause.\u00a0\u00bb<\/p>\n

Hernandez says this type of study could easily be done in other places, like Arizona, where large, remote solar farms are also becoming common. \u00ab\u00a0To be honest, this isn’t anything that an eighth-grader couldn’t do,\u00a0\u00bb she says. \u00ab\u00a0This isn’t rocket science. It’s something that could be done in every state to identify places that will make solar energy more efficient. We’re hoping that other states come on board and employ a similar decision support tool.\u00a0\u00bb<\/p>\n<\/div>\n
