Electrifying news: Solar and wind power has quintupled in a decade

Subscribe to The Beacon

Across the United States, workers are covering fields with solar panels, and big rigs are hauling massive turbine blades to wind-scoured ridgelines. This is what it looks like when renewable energy expands exponentially.

The amount of renewable electricity generated in the United States has doubled in the last 10 years, according to number-crunching out Tuesday from the U.S. Energy Information Administration.

And as impressive as doubling in a decade is, it understates the case. That’s because about 90 percent of that growth came from wind and solar: 57 million megawatt hours in 2008, and 301 million megawatt hours in 2018 — increasing more than fivefold in a decade.

So where do we stand after accounting for all that growth? Well, some 17.6 percent of the country’s power now comes from renewables.

It’s mainly electricity generated by hydroelectric dams (6.9 percent). Even after all that massive growth, wind only provides 6.5 percent and solar 2.3 percent of our electricity. Renewables like biomass and geothermal generate the last 1.9 percent.

Nuclear plants (not considered renewable but, hey, no greenhouse gases!) provided 19 percent of U.S. electricity in 2018. The remaining 63.4 percent came from fossil fuels.

That’s just electricity. If we zoom out to include all energy (petroleum for cars, natural gas for furnaces and water heaters) it’s a different picture: Renewables account for around 11 percent.

So we still have a long way to go. But consider this: If renewables sustain this rate of growth, the United States would be roughly on track to get all of its electricity from carbon-free sources by 2050. The question, of course, is whether that exponential growth can continue. The size of the job is staggering. Those solar-panel covered fields will have to be five times as big in 10 years, and 25 times as big in 20, and 125 times as large by 2050. Crazier things have happened.

The cost of installing solar energy is going to plummet again.

Toward the end of the last ice age, about 19,000 years ago, the sea rose in several large spurts, according to a new study of coral reefs that grew during this period.

This contradicts assumptions that sea level rises gradually. Instead, coral fossils show sudden inundations followed by quieter periods. This offers new information that supports the theory that glaciers and ice sheets have “tipping points” that cause their sudden collapse along with a sudden increase in sea level.

Researchers at Rice University surveyed deep-sea coral fossils in the Gulf of Mexico, scanning their 3D structures to analyze them for growth patterns. Coral likes to live close to the surface, so it grows slowly when sea level is constant. But when sea level rises quickly, the coral grows vertically to try to stay near the surface, forming terraces.

“The coral reefs’ evolution and demise have been preserved,” lead author of the study, Pankaj Khanna, said in a press release. “Their history is written in their morphology — the shapes and forms in which they grew.”

Whether the future is written in these forms, too, remains to be seen.

China plans to create 13 million clean energy jobs by 2020.

Nye first found television fame in the ’90s with his weekly children’s show on PBS. Now, he’s returning to the small screen — or, at least, the streaming device — with Bill Nye Saves the World, a Netflix series set to debut this spring.

“Each episode will tackle a topic from a scientific point of view,” Nye said in a statement, “dispelling myths, and refuting anti-scientific claims that may be espoused by politicians, religious leaders, or titans of industry.” Those topics include some hot-button issues, like vaccinations, genetically modified foods, and climate change.

Though he got his start on an uncontroversial kids’ show, in recent years Nye has not shied away from contentious issues. He’s been an especially outspoken critic of climate change deniers. Last year, he bet notorious denier Marc Marano $20,000 that 2016 would be one of the 10 hottest years on record. Morano declined the offer — which, considering the data, was probably wise.

Nye will get some help on his new show from special correspondents like Karlie Kloss. “We’ll be talking about every nerdy thing you can dream of,” says the model.

We fact-checked Donald Trump’s latest comments on renewable energy.

According to a new report from the International Energy Agency (IEA), renewable energy, mostly solar and wind, accounted for more than half of all new electric capacity added in the world last year, a 15 percent jump from 2014. Globally, there is now more renewable power capacity than coal power capacity.

Clean energy growth was especially high in China, which was responsible for about 40 percent of all new clean energy capacity. Get this: In China in 2015, two wind turbines were installed every hour.

This surge in renewables, according to the IEA, can be attributed to policy changes, lowered costs, and improvements in technology.

So renewable energy hit some big milestones last year, but it’s still just the beginning: The IEA — which has been accused of underestimating the growth of renewables — expects 28 percent of electricity to come from renewables by 2021, up from 23 percent today.

“I am pleased to see that last year was one of records for renewables and that our projections for growth over the next five years are more optimistic,” said IEA Executive Director Fatih Birol. “However, even these higher expectations remain modest compared with the huge untapped potential of renewables.”

So let’s keep this moving, folks.

Europe keeps hitting clean energy milestones

Europe keeps hitting clean energy milestones

By on May 18, 2016Share

May has been a good month for clean energy in Europe. Coal plants have faltered and wind farms are thriving, and not just in Denmark, the continent’s shining example of renewable energy. We’re whizzing by milestones right and left!

1. Portugal ran on renewables alone for four days straight

For a stretch of 107 hours over four days in early May, solar, wind, and hydro power were the only sources for Portugal’s electricity. That’s a big jump from just three years ago, the Guardian points out, when Portugal generated half its electricity from fossil fuels.

2. Germany was almost entirely powered by solar and wind

Clean energy supplied a record 87 percent of Germany’s electricity in the middle of a sunny, windy day on May 8. The country’s renewables produced so much energy the price of electricity sunk low enough that people were getting paid to use it. That’s because coal and nuclear plants couldn’t shut down fast enough to respond to the excess power.

3. Britain was powered without coal for the first time in 130 years

Britain’s electricity generated from coal fell to zero for about a third of the time between May 9 and 15. This marks the first time Britain didn’t rely on coal since 1882, when it opened the first public power station.


All these examples have one important thing in common: Renewables supplied enough electricity for days, not hours. And if renewable prices continue to fall and storage technology improves, it could be a glimpse of what’s to come on an extended basis.

Amazon’s cloud is about to get dirtier

Amazon’s cloud is about to get dirtier

×

In the latest effort to satisfy our desire to save every photo, thought, and fragment of information in cyberspace, Amazon plans to build a fat new server farm that will offer “cloud” storage for such companies as Yelp, Netflix, Pinterest, Dropbox, Spotify, Soundcloud, Tumblr, and Vine, to name more than a few.

According to the Seattle Times, the $1.1 billion server farm will be located in Dublin, Ohio. The city is served by an electric utility that gets two-thirds of its juice from coal-fired power plants, and has a history of lobbying for the coal industry.

As a Greenpeace report from earlier this year shows, not all energy-hogging data centers warm the climate equally, and Amazon’s are among the worst of the worst. Fossil fuel burning provides over half the energy used by Amazon’s colossal digital network — and nuclear power supplies another quarter. Here’s the breakdown:

Greenpeace

By contrast, the Greenpeace report raves that Apple powers the iCloud with 100 percent renewables; Facebook put a data center in Iowa to spark the world’s largest purchase of wind turbines; and Google is signing long-term contracts to buy cleaner power for some of its centers. What’s more, these three web giants teamed up in North Carolina to pressure Duke Energy, the largest U.S. utility and one of the country’s biggest emitters, to offer customers — including their data warehouses — the choice to buy greener electricity.

(Before heaping too much praise on all that progress, recall that these companies and their founders don’t have perfect track records when it comes to caring for the climate.)

To avoid adding to Amazon’s dirty energy use (and supporting its labor-abusing, writer-exploiting, bookstore-bullying, and publisher-extorting ways) we can host our websites and store our digital stuff elsewhere until the company cleans up its act — and maybe even shop in a real store like back in the old days.

Yet given Amazon’s’s dominion over many of the apps and sites we use for fun, entertainment, information, and procrastination, we’d basically have to give up our computers and all other devices to steer clear of its sovereign realm.

If all the less desirable impacts of the internet were as palpable as the gratification we get from instantly streaming the last five Parks and Recreation episodes (made possible by Amazon’s web infrastructure), it would be a lot easier to make an informed decision about how much digital property we really want.

Maybe we need an app that’ll kick a could of smoke out of the back of our laptops every time we order a bag of groceries from Amazon Fresh.

Here Comes the Son: Barry Goldwater Jr. Fights for Solar Power in Arizona

green4us

A fight over net-metering policy in the Grand Canyon State reveals some rifts among conservatives. Gage Skidmore/Flickr The name Barry Goldwater is practically synonymous with conservatism in America. That’s even more true in the late politician’s home state of Arizona, which he represented for five terms in the US Senate. Now his son, Barry Goldwater Jr., is putting the family name behind an effort to protect solar energy’s growing share of the electricity market—a struggle that has pitted him against entrenched utility interests and a right-wing dark-money group. Goldwater, 74, is the chairman of Tell Utilities Solar Won’t Be Killed (or TUSK, for short), a group launched in March to fight the state’s largest electric utility, Arizona Public Service, on solar power. APS has been campaigning to get the state utility commission to change regulations dealing with net metering, a policy that allows homes and businesses with their own solar power systems to send excess energy they generate back to the grid and make money off of it. Forty-three states and the District of Columbia have a net-metering policy in place. Arizona has had net metering since 2009, which has helped make it the second-ranked state in the country in installed solar capacity. But APS has called for an overhaul of the state’s net-metering policy and plans to unveil its proposal to the regulators on the Arizona Corporation Commission this Friday. APS argues that under the current arrangement, the 18,000 Arizonans with rooftop solar aren’t paying enough to cover the cost of maintaining the grid. Even if a house has a solar system, it still uses the utility’s infrastructure. It pulls energy from the grid when the sun is not shining and feeds energy back into the grid when the solar unit is generating more power than the house needs. The utility wants to lower the rate that it pays for solar power produced by these rooftop solar generators, or otherwise recoup the costs. “Our only point is that anybody who uses the grid should pay their fair share of the grid,” said APS spokesman Jim McDonald. Opponents, however, say reducing the incentives for rooftop solar will make it a less appealing investment. They argue that APS is going after net metering because it is worried that solar might start to cut into its profit margins, as fewer homeowners are buying from the grid and more are selling to it. McDonald said net metering has “zero impact” on the utility’s profit margins right now—but it could down the line. “Eventually would it become a business issue? It probably would,” he said. Enter Goldwater. TUSK’s sole concern is protecting net metering, and it has brought together solar industry and other business groups to push back against APS. If APS is successful, said Goldwater, “they may very well kill rooftop solar in Arizona, and that would be a tragedy.” A politician in his own right, Goldwater represented California in the US House of Representatives from 1969 to 1983. (He still lives in California, though he is active in Arizona-based conservative organizations like the Goldwater Institute, named after his father.) His support for solar, he said, comes from conservative, free-market principles rooted in “creating choices for the American consumer.” “Choice means competition. Competition drives prices down and the quality up,” Goldwater told Mother Jones. “The utilities are monopolies. They’re not used to competition. That’s what rooftop solar represents to them.” TUSK’s campaign to date has been creative, to say the least. It includes a web video of a large gorilla beating up a smaller one as a booming voice condemns the utility monopoly for “trying to kill the independent solar industry in Arizona,” before Goldwater comes on screen to say that it’s “not the American way, it’s not the conservative way.” Another ad features a song about APS sung to the tune of “Total Eclipse of the Heart.” (Chorus: “They don’t think consumers are that smart.”) The group has also been running ads on the Drudge Report and conservative radio in the state. The public relations company behind the campaign is Phoenix-based Rose + Moser + Allyn, led by Jason Rose, a well-connected member of the state’s Republican establishment. Rose’s wife, Jordan, is the founder of Rose Law Group, which represents California-based SolarCity, the county’s largest installer of rooftop solar. One environmentalist in the state described Rose, 42, to me as “a hip, young, ultra-right-wing PR guy.” I asked Rose whether he thought the description fit. “I will gladly accept that moniker,” he replied. The group hired a Republican polling firm in March to survey likely voters on solar and found that 88 percent of all voters in the state—and 76 percent of Republicans—supported net metering. “I think solar has just relied on the left for so long, and it hasn’t made a strong intellectual effort to the right. And it should,” Rose said. “Because it’s entirely consistent with that more libertarian, free-market strand of the Republican Party.” Rose thinks that Arizona is the leading edge of a solar renaissance among conservatives. “Arizona might be the key focus group on this, and might be a leading indicator of a future shift in Republican attitudes not just in Arizona, but across the country,” he argued. But his group is getting push-back from APS and its allies—most of which are also conservative. The utility is a major donor to Republican causes in the state, giving $25,000 to the Republican Victory Fund in the 2012 election, according to the Arizona Department of State records. Republicans have long held the majority in the state Legislature. The two renewable-friendly Democrats on the Corporation Commission, which will ultimately decide whether or not to approve APS’s net-metering plan, lost reelection bids last fall, leaving an entirely Republican commission. APS has pretty entrenched supporters in the state. “APS wields a lot of power,” said Tom Mackin, president of the Arizona Wildlife Federation, which isn’t involved in the net-metering fight but has worked on renewable energy issues in the state. “They pretty much get what they want.” Last week, the national conservative group 60 Plus Association entered the Arizona fight as well, with a website and web ads decrying “corporate welfare” for solar energy and raising the specter of Solyndra, the solar panel company that went bankrupt in 2011. 60 Plus bills itself as the conservative group representing senior citizens (the anti-AARP, if you will). As a 501(c)(4), the group does not have to disclose its donors. It made big outside expenditures on Republicans in 2012. While 60 Plus has weighed in on a federal renewable energy standard in the past, claiming it would be bad for senior citizens, this appears to be the first state issue the group has taken on. Renewable advocates have accused APS of funding the 60 Plus campaign, a charge that APS flatly denied in an interview with Mother Jones. But the group’s involvement is perhaps a sign of just how much attention is being paid to the net-metering fight in Arizona. Bryan Miller, president of the advocacy group Alliance for Solar Choice, recently deemed it “the most significant fight for solar in the country.” That’s why renewable energy advocates in the state say that having a voice like Goldwater’s involved is changing the game. “It really does make a big difference when a group like TUSK comes out and they say directly, ‘Look, the utilities are trying to kill solar,’” said Nancy LaPlaca, a Phoenix-based energy consultant. Goldwater paints the fight to keep net metering as going to the very heart of Republican values. “Conservatives believe in individual freedom, in choice, in competition,” he said. “We believe all of those things allow people to live a better life—to be able to choose what they want to do and not have a monopoly, or in the case of government, big government, telling them how to live their life. So it’s a very natural place for a conservative to be. I think as time goes buy you’ll see more and more Republicans vocalize this.”
