As Temperatures Drop, Can States Stop Soaring Electricity Costs by Regulating Crypto Mining?

While the Trump administration has spent 2025 slamming the brakes on U.S. expansion of  renewable energy by defunding solar and wind projects, Americans have seen their electricity costs skyrocket by more than an average of 30 percent, a trend not expected to abate any time soon.

The rapid expansion of cryptocurrency mining facilities and artificial intelligence data centers throughout the United States – requiring extraordinarily high levels of energy use, taxing electrical grids and resulting in higher electrical bills for surrounding communities throughout the …

Could Rollback of Environmental Impact Law Help California Fight Its Housing Crisis?

Earlier this summer, as part of the state’s annual budget deal, California Gov. Gavin Newsom signed legislation that alters how the existing California Environmental Quality Act (CEQA) would apply to certain housing development projects in the Golden State.

A landmark law signed in 1970 by then-governor Ronald Reagan, the CEQA was intended to reduce environmental harms by requiring public agencies to identify and mitigate potential environmental impacts of the implementation of building activities and governmental policies. Throughout the decades since the CEQA was enacted, a …

Does EtO’s Recent Regulatory Battle Victory Mean It Will Win the War?

Following years of heightened concern about the dangers of exposure to ethylene oxide (EtO), increased regulatory oversight, and a steady hum of litigation, in 2025 it seems like things might be changing for the beleaguered industry dependent upon this highly effective but potentially cancer-causing sterilizing gas. With a new administration in the White House, a U.S. Environmental Protection Agency laser focused on deregulation, and with the first defense verdict issued in an EtO case out in Colorado this past spring (covered by …

New York State Goes Nuclear

New York Gov. Kathy Hochul announced June 25 that she is directing New York Power Authority to add at least one gigawatt of new nuclear power generation by building a zero-emission nuclear power plant somewhere in upstate New York.

This announcement, four years after the 2021 closure of the Indian Point nuclear plant due to safety concerns pertaining to nuclear waste disposal, came as a surprise to many who expected the governor to, instead, recommend cap-and-invest regulations pursuant to the Climate Leadership and Community Protection …

Will Riding the Crypto Mining Wave Only Lead to Wipeout?

In the past couple of years, multiple states across the nation have made various attempts to attract cryptocurrency mining centers at which the virtual currency is “mined” on a colossal scale — a process requiring a significant amount of energy — through legislation and business and tax incentives (covered extensively by ELM, including here and here).

After what seemed like increasing setbacks for the cryptocurrency industry, major U.S. banks are now boasting cryptocurrency trading desks. Therefore, regardless of some states’ earlier challenges in …

Colorado Jury Issues First Defense Verdict after Years of EtO Exposure Lawsuits in US

A Colorado jury issued a defense verdict following a six-week trial during which four women alleged their respective cancers were caused by exposure to EtO emitted by the nearby Terumo Blood & Cell Technologies Lakewood plant over the course of several decades. They asked for a $444 million judgment.

Notably, during a years-long nationwide assessment of EtO facility emissions (covered by ELM here), the EPA previously concluded that the fence-line community living next to the Lakewood facility in Jefferson County had an elevated cancer …

New Congress Reverses Biden-Era Methane Waste Emissions Fee

Despite longstanding bipartisan support, the U.S. Senate on Feb. 27 — just as the House did the day prior — passed a resolution withdrawing the waste emissions charge (WEC), which is a fee on methane waste emissions caused by oil and gas producers.

The vote served as one of the first attempts by this Congress to apply the Congressional Review Act in order to bypass the filibuster, which requires at least 60 senators for a successful vote, instead of requiring only a simple majority vote …

Can Crypto Mining Maintain its 2025 Regulatory Hot Streak?

The election of Donald Trump back into office was cheered by cryptocurrency enthusiasts across the country for his public support of the industry. After all, the president even has his own memecoin ($TrumpCoin, of course) and has issued executive orders proclaiming support for the industry during his first days in office. Yet, even if efforts to rein in  the energy-guzzling crypto mining industry at the federal level (previously covered by ELM here and here) are abandoned, miners still face regulatory challenges targeting …

Did San Francisco Awaken the Ghost of the Chevron Doctrine? The Supreme Court Weighs In

During the first week of oral arguments of its new term, the U.S. Supreme Court heard City & County of San Francisco v. Environmental Protection Agency. (Audio of the roughly 90-minute proceedings can be found here.)

This case marks the court’s first look at the Clean Water Act following its decimation last term of the Chevron deference doctrine in Loper Bright Enterprises v. Raimondo (covered by ELM here), in which the court reversed long-standing precedent to hold that federal courts must exercise …

Cryptomining Faces More Legislative Hurdles in US

As cryptocurrency has increased its notoriety in the US, so has its demands on the US electrical grid. Indeed, the US is witnessing a constantly proliferating number of cryptomining facilities, which are large spaces – often former factories or defunct power plants – filled with computers using large amounts of electricity to “mine” crypto by solving mathematical equations as fast as possible. This drain on energy has been met with unease in some parts of the US, however, such as New York, which …
