Lawmakers in California and Massachusetts have recently introduced bills that would require their respective states to get all of its electricity from renewable energy sources.
California Senate leader Kevin de León (D-Los Angeles), who introduced SB 584 last Friday, would require the Golden State to have a carbon-free grid by 2045. It would also accelerate the state's current goal of hitting 50 percent renewables by 2030 to 2025.
De León actually helped pushed through the initial 50 percent by 2030 law two years ago, but as he told the Los Angeles Times the legislation did not go far enough.
"We probably should have shot for the stars," he said.
As InsideClimate News noted, California is already well on its way:
"The California Energy Commission says the state got about 27 percent of its electricity from renewables last year, slightly better than the 25 percent required by law. Capacity has more than doubled over the past decade. California's largest utilities have also said they are ahead of schedule for meeting their 2020 goal."
Massachusetts legislators have also announced similar clean energy efforts. HD.3357 and SD.1932 was introduced in the House of Representatives by Rep. Sean Garballey and Marjorie Decker and in the Senate by Sen. Jamie Eldridge.
The measure would require Massachusetts to get all of its electricity from renewable sources by 2035. All of its energy needs, including heating and transportation, would have to come from renewable sources by 2050.
So far, the only state that has an official 100 percent renewable energy standard is Hawaii. Hawaii's aggressive clean energy mandate—requiring the state's electricity to come from renewable sources no later than 2045—was enacted back in 2015.
Many renewable-energy loving states—as well as town and city governments—are ramping up their clean energy goals in spite of the federal government's favoritism of fossil fuels and indifference towards fighting climate change.
This month, Nevada assemblyman Chris Brook introduced a bill to ramp up the state's renewable portfolio standard to 80 percent by 2040. Nevada's current standard calls for 25 percent by 2025.
Transitioning to 100 percent clean energy is not as far-fetched as it seems.
Dr. Mark Z. Jacobson, a Stanford University professor and cofounder of The Solutions Project, has created a state-by-state roadmap to convert the country to 100 percent renewable energy by 2050.
Last year, The Solutions Project team published a study explaining how each state can replace fossil fuels by tapping into renewable resources available in each state such as wind, solar, geothermal, hydroelectric, and even small amounts of tidal and wave power.
The authors found that converting the nation's energy infrastructure into renewables is ideal because it helps fight climate change, saves lives by eliminating air pollution, creates jobs in the rapidly booming renewable energy sector and also stabilizes energy prices.
"It is now established that such a transition is possible state by state and country by country," Jacobson commented to EcoWatch in December.
Also, as USA TODAY pointed out from a University of Texas at Austin study, wind turbines and big solar farms are the cheapest sources of new electricity generation across much of the U.S. Certainly in sun-soaked California, where solar is the cheapest form of energy in much of the state.
I had the chance to take a deeper dive with Jacobson via email on Wednesday. He took the time to answer these following questions:
What do you say to the critics who say it is not feasible for California, Massachusetts (or any other state) to get to 100 percent clean energy?
Jacobson: They speak without having every studied the issue or examined the numbers, including the ability to keep the grid stable or the costs of energy.
What are some of the specific benefits for California and Massachusetts if they transition to clean energy?
Jacobson: Create more net long-term jobs than lost, stabilize energy prices because the fuel costs of wind and solar are zero, reduce the costs of energy since onshore wind and large-scale solar are the least expensive forms of new energy in the U.S. today, eliminate 13,000 air pollution deaths and hundreds of thousands of illnesses in California alone saving 3 percent of the GDP, reduce terrorism and catastrophic risk because of the more distributed nature of the grid and reduce dependence on foreign energy.
What are some of the biggest obstacles (i.e. technology, politics, fossil fuel industry) for states to get to 100 percent clean energy?
Jacobson: Lack of information and people with a financial interest in the current infrastructure. Once people have full information about the transition and its benefits, most are likely to support the transition. Ninety percent of the blockade to faster progress is due to individuals and companies that have a financial interest in the current infrastructure thus profit over it not happening.
Are you working with any of the legislators who have proposed these 100 percent clean energy bills? If so, who? And, what role is The Solutions Project playing in helping states advance renewable energy policies?
Jacobson: We provide information to all parties who request it, thus our goal is not partisan. It is purely to help facilitate the healthiest and cleanest future for Americans and the world.
How do you feel about President Trump and his administration's pro-fossil fuel agenda? Does it make the push to 100 percent clean energy harder?
Jacobson: The transition will occur regardless of what President Trump wants or does because costs are favorable and most people want healthy air and lower energy prices, and see all the benefits in terms of jobs, price stability, health and security that clean, renewable energy provides.
Even though scientists are pretty certain that wastewater injection from fracking and conventional drilling has led to the unprecedented spate of earthquakes rollicking Oklahoma, Texas and other states in recent years. Definitive proof, however, is rare. But now, in a study published Thursday in Science, researchers have fastened another nail in the "man-made earthquakes" coffin.
Using satellite imagery, the researchers found that a series of earthquakes that struck Texas between 2012 and 2013— including the largest-ever quake recorded in eastern Texas—were caused by the injection of large volumes of wastewater from oil and gas activities into deep underground wells.
As Mashable explained from the study:
Wastewater not only puts pressure on underground fault lines, causing "induced" earthquakes, but also pushes up the surface of the ground—a phenomenon called "uplifting" that can be seen from space.
Researchers used satellite images of ground uplifting to show how wastewater disposal in eastern Texas eventually triggered a magnitude-4.8 earthquake in May 2012, the largest earthquake recorded in that half of the Lone Star state.
"Our research is the first to provide an answer to the questions of why some wastewater injection causes earthquakes, where it starts and why it stops," said study co-author William Ellsworth, a geophysics professor at Stanford's School of Earth, Energy & Environmental Sciences.
As a Stanford press release described, the researchers used Interferometric Synthetic Aperture Radar (or satellite-based radar) to detect tiny, highly precise deformations near four high-volume wastewater disposal wells where the 2012 temblor occurred.
These wells had operated between 2005 and 2007, injecting about 200 million gallons of wastewater annually underground at its peak—or, as Science pointed out, "about an Olympic swimming pool's worth of wastewater pumped underground each day."
This uplift, as a result of pumping so much fluid into the ground, caused the terrain between two sets of injection wells to bulge up to 3 millimeters a year on average between May 2007 and November 2010, Science noted. Over time, excess fluids seeped away from the injection point into tiny spaces in surrounding subsurface rocks, boosting water pressure—aka pore pressure. The ever-expanding pore pressure then reached fault zones, thus triggering earthquakes.
As explained in the Stanford press release, the rising pore pressure built up until it triggered earthquakes in 2012 along an ancient fault line. "The quakes ended in late 2013, when pressures began to decline after wastewater injections were scaled back considerably," it stated.
Fracking has become an increasingly controversial oil and gas extraction method especially due to its briney, chemically laden wastewater byproduct. Every day, two billion gallons of this wastewater is injected into roughly 180,000 disposal wells scattered throughout states such as Texas, California, Oklahoma and Kansas.
Mounting evidence shows that this injecting of wastewater is causing damaging earthquakes in areas that had never seen much seismic activity, especially in Oklahoma, which has surpassed California in becoming the country's earthquake capital. Just this month, the Sooner State was rocked by a 5.8 earthquake in Pawnee, the largest ever in the state.
Dauntingly, the researchers in the current study found that seismic activity increased even as wastewater injection rates declined because pore pressure from earlier injections continuing to diffuse.
On an industry-positive note, this research presents a new tool to pinpoint which earthquakes are man-made or natural and to even forecast further seismic activity.
Arizona State University geophysicist and study co-author Manoochehr Shirzaei called the findings "very groundbreaking" and "very new," and explained how this study can, in a sense, make wastewater disposal safer.
"This research opens new possibilities for the operation of wastewater disposal wells in ways that could reduce earthquake hazards," Shirzaei said. Shirzaei indicated he was neither pro or against fracking.
"So now the goal, the scope of every scientist across the U.S.A., and maybe abroad, is to make that injection safer" by "reducing the number of earthquakes as much as we can," he said.
