California becomes first state to eliminate subsidies for gas line extensions amid electrification push

9/19/2022

 
The California Public Utilities Commission on Thursday unanimously voted to entirely eliminate ratepayer subsidies for the extension of new gas lines beginning in July, amid a statewide push to decarbonize the building sector.  Current subsidies for gas line extensions are “a vestige of the past,” dating back to an era when the state wanted to promote the expansion of the gas system — but that policy no longer makes sense in light of California’s greenhouse gas emission reduction goals, CPUC Commissioner Clifford Rechtschaffen said at the agency’s voting meeting.- Utility Dive

Criticism intensifies after big oil admits ‘gaslighting’ public over green aims

9/19/2022

 
Criticism in the US of the oil industry’s obfuscation over the climate crisis is intensifying after internal documents showed companies attempted to distance themselves from agreed climate goals, admitted “gaslighting” the public over purported efforts to go green, and even wished critical activists be infested by bedbugs. The communications were unveiled as part of a congressional hearing held in Washington DC, where an investigation into the role of fossil fuels in driving the climate crisis produced documents obtained from the oil giants ExxonMobil, Chevron, Shell and BP. - Guardian

Federal report boosts plan to remove 4 dams on Calif river

9/1/2022

 
Federal regulators on Friday issued a final environmental impact statement that supports the demolition of four massive dams on Northern California’s Klamath River to save imperiled migratory salmon. The staff's recommendation, which largely echoes an earlier draft opinion, tees up a vote on the roughly $500 million project by the five-member Federal Energy Regulatory Commission later this year. The removal of the four hydroelectric dams on the lower Klamath River — one in southern Oregon and three in California — would be the largest dam demolition project in U.S. history. The aging dams near the Oregon-California border were built before current environmental regulations and essentially cut the 253-mile-long (407-kilometer-long) river in half for migrating salmon. Migratory salmon have been hit hard by warming waters and low river flows caused by severe drought and competition for water with agricultural interests. - ABC News

Transforming skyscrapers into gravity batteries

9/1/2022

 
Gravitational accumulation is no longer a novelty. Since 2012, the so-called “gravity batteries” have made their official debut in the world of energy storage. And today more than one company has demonstrated its potential thanks to full-scale projects that exploit mineral wells, quarries or mountains. But researchers at the International Institute for Applied Systems Analysis (IIASA) in Vienna, Austria, want to take technology to another level. Or, better, in another environment: that densely urbanized metropolis. In a new study published in the journal Energy, scientists proposed to transform skyscrapers into gigantic gravity battery. How? Through their Lift Energy Storage System, a system that would exploit lift systems and empty apartments to store energy in very high buildings. The idea is to accumulate energy by lifting containers of wet sand or other high-density materials. Basically, the LEST would benefit from any downtime of the lift, moving the sand from the bottom of the building upwards, in case of an excess of electricity production on the grid. And from top to bottom to release energy when electricity demand rises. - SEN

Misinformation is derailing renewable energy projects across the United States

9/1/2022

 
On a winter night in early 2016, Jeremy Kitson gathered in his buddy's large shed with some neighbors to plan their fight against a proposed wind farm in rural Van Wert County, Ohio. The project would be about a mile from his home. From the beginning, Kitson — who teaches physics and chemistry at the local high school — knew he didn't want the turbines anywhere near him. He had heard from folks who lived near another wind project about 10 miles away that the turbines were noisy and that they couldn't sleep. "There were so many people saying that it's horrible, you do not want to live under these things,'" Kitson says. - NPR

Wind and Solar Are Saving Texans $20 Million a Day

8/21/2022

 
In a year of record-high prices for fossil fuels, as lawmakers consider new policies that can help fight inflation, renewable energy is already helping to shield Americans from steep jumps in their electricity bills. For example, in Texas, even as some observers have incorrectly blamed renewables for the state’s strained power grid, more than a third of electricity in the first half of 2022 came from wind and solar projects. Wind and solar have both set records already this year. High production from renewables and high fossil fuel prices together mean wind and solar are having an outsized impact on lowering energy costs. Based on benchmark natural gas prices, RMI estimates that, on average, wind and solar projects in Texas have avoided $20 million per day in fuel that otherwise would have been needed for fossil fuel-based power plants to meet electricity demand.- RMI

Strip Mining Worsened the Severity of Deadly Kentucky Floods, Say Former Mining Regulators. They Are Calling for an Investigation

8/21/2022

 
Two former state and federal mining regulators say state and federal authorities should investigate the role strip mining played in last week’s devastating and deadly flooding in eastern Kentucky and the condition of the mines after the torrential rainfall. The Kentucky counties, and areas of West Virginia and Virginia, flooded by torrential rains have for decades been heavily logged and strip-mined for coal—land-use practices that dramatically alter the landscape and contribute to flooding. The recent flooding has killed at least 37 people. With strip mining, trees are the first to go. Then, hundreds of feet of rock may be  blasted away from the tops or sides of mountains to get at underground seams of coal. - Inside Climate News

Electric Vehicles Have the Lowest Annual Fuel Cost of All Light-Duty Vehicles

8/21/2022

 
Estimates of annual fuel costs for model year (MY) 2022 light-duty vehicles show that electric vehicles (EVs) can save consumers thousands of dollars over gasoline or diesel vehicles. All EV models had annual fuel costs less than $1,000. The only vehicle types with cost estimates between $1,000 and $2,000 were plug-in hybrid electric (PHEV) and hybrid electric (HEV) models. Models with an annual fuel cost estimate of $2,000 to $7,000 were dominated by conventional gasoline models. The small car category has a wide breadth of fuel costs because it not only includes fuel-efficient small cars, but also luxury sportscars with low fuel economies. - Energy,gov

Saudi Aramco: Oil giant tops own record with $48.4bn quarterly profit

8/21/2022

 
Saudi oil giant Aramco has broken its own record with a $48.4bn (£40bn) profit for the second quarter of 2022. It is a 90% year-on-year increase and marks the biggest earnings for the world's largest energy exporter since its public listing three years ago. Russia's invasion of Ukraine has seen oil and gas prices skyrocket. Russia is one of the world's biggest exporters but Western nations have pledged to curb their dependence on the country for their energy needs. According to Bloomberg, the Saudi oil giant's figure represents "the biggest quarterly adjusted profit of any listed company". As well as the record profits, the state-owned Saudi energy giant announced it would keep its dividend unchanged at $18.8bn for the third quarter. - BBC

State Tensions Rise As Water Cuts Deepen On The Colorado River

8/21/2022

 
As a 23-year-old drought intensified by climate change and overallocation continue to endanger the Colorado River water supply, Arizona, Nevada and Mexico will face more reductions in their allotments, the U.S. Bureau of Reclamation announced Tuesday.  According to new projections by the Department of Interior, the river’s main reservoir, Lake Mead in Nevada, will reach record low levels in January, triggering a “Tier 2a” shortage that calls for a collective reduction in Colorado River use by Arizona, Nevada and Mexico. About 80 percent of the more than 720,000 acre-feet reduction will come from Arizona. California would not be impacted by the newly declared shortage because the reductions are based on previously negotiated levels. - Inside Climate News

How The Inflation Reduction Act Will Spur a New Climate Tech Ecosystem

8/21/2022

 
On the surface, the Inflation Reduction Act that President Biden signed into law on Tuesday may sound like a massive government spending program. Indeed, it promises to put nearly $370 billion in federal funding behind the energy transition. But, if you dig deeper, the IRA is less about the power of government spending and more about the power of the private sector. The tax incentives, loans, and grants at its center are all intended to nudge the private sector to go faster in deploying existing technologies like wind and solar while also advancing future technologies. “The path they went down is 100% the ‘sweeten the deal path,’” says Karen Karniol-Tambour, chief investment officer for sustainability at Bridgewater. “Let’s just give lots of incentives to make the green stuff really competitive.” - Time

New Climate Maps Show a Transformed United States

8/21/2022

 
According to new data from the Rhodium Group analyzed by ProPublica and The New York Times Magazine, warming temperatures and changing rainfall will drive agriculture and temperate climates northward, while sea level rise will consume coastlines and dangerous levels of humidity will swamp the Mississippi River valley. Taken with other recent research showing that the most habitable climate in North America will shift northward and the incidence of large fires will increase across the country, this suggests that the climate crisis will profoundly interrupt the way we live and farm in the United States. See how the North American places where humans have lived for thousands of years will shift and what changes are in store for your county. - ProPublica

Four Ways the Inflation Reduction Act Speeds Shift to a Cleaner, More Affordable Energy Future

8/21/2022

 
The passage of the Inflation Reduction Act (IRA) is a once-in-a-career opportunity, permanently shifting the course of both the US economy and global climate to a better future. And it represents the culmination of decades of work by RMI — our experts and analysis played a direct role advancing key provisions — along with countless other NGOs, businesses, communities, scientists, and policymakers The full implications of the nearly 800-page bill continue to be assessed. But early modeling suggests its incentives will drive dramatic emission reductions: at least 40 percent by 2030, just shy of US commitments to lower emissions by half in that time. - RMI

New US Climate Law Will Reduce Carbon Emissions & Make Electricity Less Expensive Economists Say

8/21/2022

 
U.S. consumers are expected to save money on their electricity bills under the nation’s first comprehensive climate law—perhaps more than $200 billion over the next decade, economists project. Even utilities are talking about eased prices at the same time they are detailing new clean energy investments. The potential price drop flies in the face of an argument made by climate action foes for years—that a move to cleaner power will mean higher energy prices for U.S. homes and businesses. Instead, the Inflation Reduction Act signed this week by President Joe Biden will direct government support to companies that invest in and generate carbon-free power, lowering their costs in a way that will enable them to pass those savings to their customers, analysts say. - Inside Climate News

Oyster reefs in Texas are disappearing. Fishermen there fear their jobs will too

4/29/2022

 
At Johny Jurisich's family dock in Texas City, more than a dozen empty oyster boats with names like Sunshine and Captain Fox lazily float in the marina on a recent Monday morning – an odd sight for what is normally peak oyster harvesting season. "On a Monday morning, this beautiful weather, they would all be out there (in the bay). This would be an empty marina," says Jurisich, whose family owns the wholesale company US Sea Products and has worked in the oyster business for generations. Nearby at Misho's Oyster Company in San Leon, mariachi music blares into an empty shucking room, the conveyor belts at a standstill. Just a few dozen oyster sacks line what would normally be a full freezer room. Currently, 25 of the state's 27 harvesting areas are already closed. The season normally runs from Nov. 1 through April 30, but many of the areas have been closed since mid-December – a move the state says is necessary for future sustainability. - NPR

Texas stumbles in its effort to punish green financial firms

4/29/2022

 
For years, fossil fuel producing states have watched investors shy away from companies causing the climate crisis. Last year, one state decided to push back. Texas passed a law treating financial companies shunning fossil fuels the same way it treated companies that did business with Iran, or Sudan: boycott them. "This bill sent a strong message to both Washington and Wall Street that if you boycott Texas energy, then Texas will boycott you," Texas Representative Phil King said from the floor of the Texas legislature during deliberations on the bill, SB 13, last year. But the Lone Star state is straining to implement the law. Loopholes and exceptions written into the law could sap its impact on financial firms that have aggressive climate policies. - NPR

A Quiet Revolution: Southwest Cities Learn to Thrive Amid Drought

4/29/2022

 
In the rolling hills around San Diego and its suburbs, the rumble of bulldozers and the whine of power saws fill the air as a slew of new homes and apartments rise up. The region is booming, its population growing at a rate of about 1 percent a year. This, in spite of the fact that Southern California, along with much of the West, is in the midst of what experts call a megadrought that some believe may not be a temporary, one-off occurrence, but a recurring event or even a climate change-driven permanent “aridification” of the West. The drought is so bad that last year federal officials ordered cuts to water provided to the region by the Colorado River for the first time in history. Water officials in San Diego, though, say they are not worried. “We have sufficient supplies now and in the future,” said Sandra Kerl, general manager of the San Diego Water Authority. “We recently did a stress test, and we are good until 2045” and even beyond. - Yale Environment350

What Is the Keystone XL Pipeline?

4/16/2022

 
The Keystone XL pipeline extension, proposed by TC Energy (then TransCanada) in 2008, was initially designed to transport the planet’s dirtiest fossil fuel, tar sands oil, to market—and fast. As an expansion of the company’s existing Keystone Pipeline System, which has been operating since 2010 (and continues to send Canadian tar sands crude oil from Alberta to various processing hubs in the middle of the United States), the pipeline promised to dramatically increase capacity to process the 168 billion barrels of crude oil locked up under Canada’s boreal forest. It was expected to transport 830,000 barrels of Alberta tar sands oil per day to refineries on the Gulf Coast of Texas. From the refineries, the oil would be sent chiefly overseas—not to gasoline pumps in the United States. - NRDC

AZ regulators deny SRP gas plant expansion, citing community impacts and insufficient supporting evidence

4/13/2022

 
​The Arizona Corporation Commission on Tuesday voted 4-1 to deny an 820-MW expansion at a gas plant proposed by Salt River Project. Regulators said there was insufficient evidence in the record to make a decision, and the expansion would put too much pressure on the nearby, historically-Black community of Randolph. - Utility Dive

Powell’s looming power problem

4/12/2022

 
Over the last two decades, climate change-induced drought and increasing water demand have depleted Lake Powell substantially: It is now less than one-fourth full. As water levels drop, so, too, does the potential energy of the falling water. That, in turn, lowers the turbines’ generating capacity and power output. In the 1990s, the dam produced as much as 7,000 gigawatt hours per year, enough to power nearly 600,000 homes. Last year, it was down to just 3,000 gigawatt hours. - HCN

The future cost of climate inaction? $2 trillion a year, says the government

4/7/2022

 
With time running out to head off the worst damage from climate change, the United States government is starting to quantify the cost of inaction – for taxpayers. The White House Office of Management and Budget (OMB) released the first ever accounting of how unchecked global warming would impact the federal budget, looking at its potential to dampen the economy as a whole, and balloon the costs of climate-related programs over time. "The fiscal risk of climate change is immense," wrote Candace Vahlsing, Associate Director for Climate, Energy, Environment, and Science at OMB, and Danny Yagan, Chief Economist at OMB, in a blog post discussing the analysis. -NPR

SRP’s baffling, costly natural gas expansion (Op-Ed)

4/7/2022

 
The U.S. power generation market has changed dramatically over the past five years. Natural gas has been bleeding market share to cheaper sources of electricity, which include solar, wind, and even nuclear. At roughly $5 per MMbtu, the price of natural gas today is more than double what it was just two years ago. Even at half of that price, natural gas has been unable to compete with solar in the Southwest. - AZ Capitol Times
