Still cheaper than coal – a report on the economics of solar power in Colorado

By Rama Zakaria, Graham McCahan

A newly-updated report is shedding light on what President Trump’s solar trade tariffs may mean for one state – and underscoring a tremendous opportunity to move forward toward clean energy, with all the benefits it can bring.

Xcel Energy filed its 30-day bid report update with the Colorado Public Utilities Commission on March 1. The update follows Xcel’s filing at the end of last year, in response to an “all-source solicitation,” as part of its Electric Resource Plan and its proposed Colorado Energy Plan.

Xcel’s plan would shut down two units at the Comanche coal plant in Pueblo, Colorado, and replace the capacity with a mix of lower-carbon resources. Earlier results were unprecedented, with more than 80 percent of the bids coming from renewable energy and storage at incredibly cheap prices.

Xcel then provided bidders an opportunity to refresh their bids following President Trump’s final decision in the Suniva/SolarWorld trade case in January, which imposed tariffs on imported solar equipment.

The refreshed bids in Xcel’s updated report show minimal change relative to last year’s results and confirm that new wind and solar power in Colorado continues to be cheaper than existing coal plants – despite the trade tariffs. Read More »

New England’s energy future lies in the balance

As recent and ongoing activity regarding fuel security, renewable energy procurement and natural gas infrastructure make clear, the energy system in New England is at a critical juncture, the responses and solutions to which will shape the region’s economy for the next 30 years or more.

ISO-NE, the regional electricity grid operator, released its fuel security study raising legitimate reliability concerns based largely on the sufficiency of pipeline infrastructure and expanding deployment of renewable energy. Meanwhile, the Federal Energy Regulatory Commission (FERC) initiated a comprehensive review of electric system resiliency, including reliability and fuel security. Read More »

Federal rollbacks + huge new oil and gas project = trouble for Wyoming

This blog was co-authored by Jon Goldstein and Sara Brodnax

Last week, the U.S. Department of the Interior’s Bureau of Land Management collected comments from citizens and groups concerned about the impacts of a proposed 5,000-well oil and gas project in eastern Wyoming.

The situation has a troubling irony, because as BLM reviews the project’s environmental risks, it is simultaneously working to roll back its own commonsense standards to stop oil and gas companies from venting, flaring, and leaking away pollution and valuable natural gas.

It’s the same story for the greater sage-grouse, which without strong mitigation measures will likely abandon critical breeding sites in the area set to be impacted by the planned oil and gas project. Here, too, BLM has signaled several attempts to unravel the collaborative, decades-forged plans to protect the imperiled bird.

The combination of weakening policies while expanding development could have disastrous consequences for Wyoming and other western states if methane pollution goes unchecked and the greater sage-grouse continues to decline.

New research shows Canada’s methane emissions problem is even worse, but it’s not hopeless

This post was co-authored by Dr. Daniel Zavala-Araiza.

New direct emissions data from oil and gas fields in Alberta should be a warning to regulators in Ottawa and Edmonton as they each prepare their methane regulations. A new study concluded that oil and gas methane emissions are 15 times higher than industry reports for 60 production sites measured in Red Deer. The discrepancy highlights the importance of strong federal and provincial regulations to address a problem science is continually showing to be much worse than industry claims it is. Strong regulations will show the world that Canadian gas can compete with lower-carbon gas supplies.

The research, published today in Elementa, uncovered that methane emissions from the oil and gas industry in Red Deer, Alberta are larger than companies estimate and that methane “super emitters,” a phenomenon we found in the U.S. oil and gas industry, may be just as much of a problem in Canada.

Could wastewater from oil and gas production help solve our water crisis? Not without better science

Climate change is drastically raising demands on the world’s fresh water supplies, and as a result, governments, scientists, and others are actively searching for new ways to manage and preserve our water resources.

One consideration includes repurposing wastewater generated from on-shore oil and gas development, which produces a whopping 900 billion gallons of water annually in the U.S. alone.

Some proponents of this option believe produced water may be a massive opportunity for water-scarce regions. Researchers at the University of Texas suggest recycling produced water for hydraulic fracturing operations could help address anticipated water shortage problems in the Permian Basin. Recycling wastewater within the oilfield is a viable option – as long as the spill and leaks, which can have significant and long-lasting negative impacts on soil and water resources, are minimized.

However, uses beyond the oilfield are much riskier if we don’t answer some critical questions first.

Tech for change video series: No peace of mind

This post is part 2 of EDF’s Tech for Change series, which aims to spotlight the way pollution-sensing technology can protect public health and the environment in California. Watch part 1 or 3

Oil and gas operations have existed for decades in California’s Central Valley and the greater Los Angeles area, but many people may not realize that over 3,500 active oil and gas wells dot LA County alone. These wells exist near schools, hospitals, and homes – which is cause for concern since oil and gas wells are known to emit dangerous chemicals like benzene, a known carcinogen.

So, what’s being done to ensure we have accurate, timely information about pollution coming from these oilfields? Very little. Few regulations require pollution monitoring at California’s oil and gas wells.
