We Have Some Really Good News About How America Uses Energy

Matt Young/AP


When you read headlines about how Congress is rife with climate change deniers and willing to vote in favor of a massive oil pipeline that could increase greenhouse gas emissions, it’s easy to get discouraged about the direction the US is headed on global warming. But when you look at some of the hard numbers about how Americans are getting their energy, there’s actually a lot to be excited about.

This morning Bloomberg New Energy Finance released a fat report on the state of US energy, and it’s chock-full of kickass facts and figures that reveal real, tangible progress on reversing the habits that cause climate change. Here are just a few of the most salient bits:

The US is getting way more efficient. It used to be that electricity demand rose and fell roughly in line with economic productivity. That’s no longer the case: Thanks to massive gains in energy efficiency in everything from home appliances to factory lines, energy demand is now less tied to economic growth than ever before. In fact, since 2007, electricity demand hasn’t grown at all, the report finds. Zero. Another way to say that is that the US is becoming more “energy productive,” meaning the US is using fewer units of energy for every unit of GDP. Energy productivity has increased 54 percent since 1990:

Since energy makes up about 83 percent of America’s total carbon footprint, those gains in efficiency (along with big shakeups in where our energy comes from, which I’ll get to shortly) have helped drive total carbon emissions down 9.2 percent from their 2007 all-time peak:

Coal is getting the boot. Coal used to provide half or more of the country’s electricity. Now, that number is down to 39 percent, thanks largely to increasing reliance on natural gas made plentiful and cheap by the fracking boom. Both production and consumption of natural gas were at all-time highs in 2014:

Renewable energy is blowing up. Natural gas isn’t the only big winner: Renewables are skyrocketing too. Solar and wind production have more than tripled since 2008. The share of all renewable energy sources combined (including large hydropower dams) in the US energy mix has nearly doubled since 2008, from 8 percent to 13 percent. This chart shows how much new capacity of each energy source was added in each year; the grey is natural gas and the light blue is renewables:

As we’ve reported before, solar is going gangbusters; the bars below show how much rooftop solar was added each year, and the red line represents the cumulative total:

Behind that trend is an ongoing freefall in the cost of solar panels. This chart shows how the more solar that gets installed, the cheaper each unit of it becomes, thanks to technology improvements and breakneck production at Chinese factories. The two lines are for different types of modules, but the important thing is that they’re both headed downhill:

BNEF

Cars are cleaner, and we’re using them less. Gasoline consumption is down 8.6 percent from 2005, which the report attributes to “increasing vehicle efficiency prompted by federal policy, increasing consumer preference for less thirsty vehicles, changing driving patterns (declining number of vehicles on the road, declining miles per vehicle), and increasing biofuel blending.” The relative climate benefits of biofuels are still being hotly debated, but the rest of those trends are pretty objectively awesome. The trend for electric vehicles is less impressive. Although the number of public electric vehicle charging stations has exploded 470 percent since 2011, sales are pretty ho-hum. The report blames low oil prices:

AN IMPORTANT UPDATE

We’re falling behind our online fundraising goals and we can’t sustain coming up short on donations month after month. Perhaps you’ve heard? It is impossibly hard in the news business right now, with layoffs intensifying and fancy new startups and funding going kaput.

The crisis facing journalism and democracy isn’t going away anytime soon. And neither is Mother Jones, our readers, or our unique way of doing in-depth reporting that exists to bring about change.

Which is exactly why, despite the challenges we face, we just took a big gulp and joined forces with the Center for Investigative Reporting, a team of ace journalists who create the amazing podcast and public radio show Reveal.

If you can part with even just a few bucks, please help us pick up the pace of donations. We simply can’t afford to keep falling behind on our fundraising targets month after month.

Editor-in-Chief Clara Jeffery said it well to our team recently, and that team 100 percent includes readers like you who make it all possible: “This is a year to prove that we can pull off this merger, grow our audiences and impact, attract more funding and keep growing. More broadly, it’s a year when the very future of both journalism and democracy is on the line. We have to go for every important story, every reader/listener/viewer, and leave it all on the field. I’m very proud of all the hard work that’s gotten us to this moment, and confident that we can meet it.”

Let’s do this. If you can right now, please support Mother Jones and investigative journalism with an urgently needed donation today.
