Every time you switch on a light, charge your electronics or heat your home in the winter, you’re relying upon a tremendous network of energy infrastructure that literally stretches across the country: power plants, pipelines, transmission wires and storage facilities.

It can be hard to visualize all this infrastructure and understand how it makes abundant energy available throughout the country. A map, though, can be a beautiful way of seeing a bigger picture—and a new map, released yesterday by the U.S. Energy Information Administration, combines a wide range of data (the locations of different types of power plants, electricity lines, natural gas pipelines, refineries, storage facilities and more) into an elegant, interactive interface that helps you understand how it all fits together. You can also zoom in on your own city or region to see the types of power plants generating electricity nearby.

The map also includes layers of real-time information on storm movement and risks, and the main intention of making all this data public is to allow utility officials and energy analysts to better understand the potential impact of storms, with hurricane season set to start. But simply playing around with the map can provide interesting insights about the state of our energy infrastructure today.

Here are a few of them, along with the percentage of U.S. electricity generation each power source currently provides:

Fossil Fuels Still Rule (Coal, 37%; Natural Gas, 30%; Petroleum, 1%)

Our capacity to generate renewable energy has certainly grown in recent years, but looking at the map (and the data), one thing is clear: coal (black), natural gas (light blue) and oil-burning (tan) power plants are still the most plentiful forms of electricity generation we have. Coal plants are especially common east of the Mississippi—a relic of the fact that most U.S. coal was once mined in West Virginia, Pennsylvania and Kentucky (PDF), even though the majority now comes from Wyoming’s Powder River Basin. Oil and natural gas plants, meanwhile, are distributed pretty evenly among population centers across the country, with the former slightly more common in the North and East, and the latter a bit more common across the South.

Nuclear Power Could be in Your Backyard (19%)

Although no new nuclear power reactors have been built since 1997, there are still 65 in operation nationally, and most are relatively close to large population centers. More than 16 million people live within 18 miles of one of these plants, the radius that Japanese officials evacuated after the 2011 Fukushima disaster. Despite the potential danger they might pose, though, nuclear plants provide far more electricity than any other non-fossil fuel option—and as a result, they reduce the amount of carbon dioxide emitted by our country as a whole.

Hydroelectric is Crucial (7%)

Hydropower was among the first electricity technologies to be implemented on a wide scale—a power station situated on Niagara Falls began supplying electricity way back in 1881—and it’s still way ahead of the other renewable options. Hydroelectric plants are largely clustered in three areas: New England, the Middle South (partly as a result of the Depression-era Tennessee Valley Authority Project) and the West.

Wind is Growing (3.46%)

Of all new electricity capacity built from 2008 to 2012, 36.5 percent came from wind, and it shows: Turbines can now be found in most regions of the country with sufficient wind speeds. They’re especially prevalent in the Midwest, where consistent and strong winds blow across the plains year-round. In total, large-scale wind projects have been built in 39 states, with many more in the works. The map above shows turbines (grey) against a background displaying real-time wind speeds, with green arrows indicating slowest winds, then orange showing middle speeds and red showing fastest.

Solar is Slower (0.11%)

Compared to wind, another main source of renewable energy—solar power—has grown at a considerably slower rate, mostly because it’s much more expensive. Still, though, several major projects have been built, including the Agua Caliente Solar Project in Arizona, which produces more photovoltaic energy than any other plant globally, and the Solar Energy Generating Systems in California’s Mojave Desert, which is the largest solar thermal energy project (generating electricity by harnessing solar power to produce heat) in the world.

There is a Ton of Natural Gas Pipeline

It’s hard to truly appreciate how much natural gas pipeline has been laid in this country until you look at the map and see for yourself. To put it in perspective, there are more than 305,000 miles of pipeline nationally, as compared to about 47,000 miles of interstate highway.

The Strategic Petroleum Reserve is a Real Place

When it’s discussed in the news, the Strategic Petroleum Reserve is mainly discussed in the abstract, an emergency supply of oil that we can use if our supply were to be disrupted. As a result, many people imagine it as a distributed, perhaps even hypothetical entity. Not true: This supply of nearly 700 million barrels of petroleum is held in four particular storage locations in Louisiana and Texas, near many of the refineries where it’s made from crude oil.

Of course, these are far from the only insights to be gained from tinkering with the map, packed with more than 20 layers of data on everything from geothermal power to offshore oil platforms to electricity transmission lines.
