Geothermal Energy: From Afterthought to American Powerhouse?

American energy policy has long been characterized by partisan divides, but one source is quietly gaining bipartisan traction: geothermal energy. For decades, geothermal remained a niche player, overshadowed by fossil fuels and, more recently, renewables like wind, and solar. However, a confluence of factors is positioning geothermal for significant expansion, potentially reshaping the U.S. Energy landscape.

Harnessing Earth’s Heat: A History of Potential

Geothermal energy, which taps into the Earth’s internal heat, isn’t a new concept. The world’s first geothermal power plant opened in Italy in 1913 and continues to operate today. Unlike wind and solar, geothermal provides firm baseload power, meaning it’s consistently available regardless of weather conditions. Despite this advantage, geothermal has historically accounted for less than 1% of total U.S. Electricity production, limited by high upfront costs and geological constraints.

Beyond Electricity: The Rise of Ground-Source Heat Pumps

A key driver of geothermal’s resurgence is the growing popularity of ground-source heat pumps. These systems utilize shallow geothermal resources for heating and cooling buildings, requiring borehole depths of only 100 to 400 feet – significantly less than the mile-plus depths needed for geothermal electricity generation. These pumps are becoming increasingly competitive with traditional HVAC systems, offering substantial energy cost reductions and long-term durability. Ball State University in Indiana, for example, replaced aging coal boilers with a campus-wide geothermal district heating and cooling system.

Fracking Technology Fuels Geothermal Innovation

Surprisingly, technologies developed for oil and gas extraction, including hydraulic fracturing and horizontal drilling, are now being adapted to enhance geothermal energy production. These techniques, collectively known as “enhanced geothermal systems,” are expanding access to geothermal resources, particularly in areas with existing fossil fuel infrastructure. States with lengthy histories of oil and gas extraction are well-positioned to leverage this expertise. California currently leads geothermal power generation, but Nevada has the highest potential for growth.

Policy Shifts and Bipartisan Support

Geothermal is gaining political traction due to its lack of historical baggage – it doesn’t carry the same environmental concerns as fossil fuels or nuclear energy. Representative Susie Lee (D-Nev.) has noted the unusual bipartisan support, stating that geothermal energy is “uniting the right, left, and center.” This support is translating into policy changes and increased investment, with plans for major new production facilities in Nevada and New Mexico, driven by investments from companies like Google and Meta to power data centers with clean, firm energy.

Global Lessons and Best Practices

The United States can learn from international leaders in geothermal energy. Iceland currently provides 30% of its total electricity and 90% of its heating and cooling from geothermal sources. Kenya relies on geothermal electricity for nearly half of its power, the highest rate globally. New Zealand derives one-fifth of its electricity from geothermal and is collaborating with Iceland on “superhot” geothermal development. These nations offer valuable insights into effective siting policies, royalty systems, and regulatory frameworks.

Navigating the Challenges Ahead

Despite the positive momentum, challenges remain. Permit reform is needed to accelerate project approvals while ensuring environmental safeguards. Concerns have been raised regarding potential methane and hydrogen sulfide releases, aquifer contamination, and drilling-induced seismicity. Improving transmission capacity, developing modern royalty systems, and building governmental expertise are similarly crucial for sustained growth.

Los Angeles, Bay Area voters will decide whether to hike already high sales taxes | Dan Walters | Dan-walters

written by Rachel Morgan News Editor

California voters face a busy election year, with decisions looming on a new governor, state legislators, and a series of ballot measures. Simultaneously, local officials in Los Angeles County and the San Francisco Bay Area are seeking voter approval for increased sales tax rates, already among the highest in the nation.

Tax Increases on the Ballot

Los Angeles County officials are asking voters in the June primary to add a half percentage point to sales tax rates, which already exceed 10% in many cities. This increase is intended to offset a projected $2.4 billion reduction in federal healthcare funding over the next three years, according to Los Angeles County Supervisor Holly Mitchell.

In the Bay Area, voters in four counties will consider a half percentage point increase in November, while San Francisco voters will be asked to approve a full percentage point increase. These proposed taxes aim to address operating deficits within the Bay Area Rapid Transit (BART) system and local bus and trolley services.

Did You Know? California consumers spend approximately one trillion dollars annually on taxable goods.

Erosion of Tax Limitations

These proposed tax hikes continue a trend of circumventing a state law that limits local add-on taxes to 2 percentage points above the statewide rate of 7.25%. Local officials routinely seek waivers from the Legislature to exceed this cap, and those waivers are typically granted.

Currently, California’s average sales tax rate, including local overrides, is 8.99%, making it the seventh highest in the country. Some cities in Los Angeles County already have rates as high as 11.25%.

Controversy and Concerns

The proposed tax increases are not without opposition. The California Contract Cities Association, representing 73 cities in Los Angeles County, has voiced concerns that a county-wide half percentage point increase could hinder cities’ ability to pursue their own tax measures. According to the association’s executive officer, Marcel Rodarte, cities have expressed that the county tax increase “makes it more difficult for cities” to raise their own rates.

Expert Insight: The repeated reliance on tax increases to address ongoing operational costs, particularly for transit systems, suggests a deeper issue of financial sustainability and a potential failure to adapt to changing circumstances.

The Bay Area transit tax measure likewise reignites debate over the financial practices of BART and other transit systems, with critics questioning whether they are adequately adjusting to decreased ridership following the COVID-19 pandemic.

Governor Gavin Newsom and the Legislature have provided the Bay Area transit systems with a $590 million loan, contingent upon voter approval of the tax increase, which is estimated to generate $980 million annually.

Some critics, like Bay Area News Group columnist Daniel Borenstein, suggest transit officials are using scare tactics by warning of service cuts if the tax measure fails, particularly given BART’s current low ridership levels despite maintaining a high level of service.

Frequently Asked Questions

What is being asked of voters in Los Angeles County?

Voters in Los Angeles County will decide in the June primary election whether to add a half percentage point to the sales tax rate to offset reductions in federal healthcare spending.

What is the current average sales tax rate in California?

The average sales tax rate in California is 8.99%, according to the Tax Foundation.

What is the state’s role in local tax increases?

Local officials routinely question the Legislature to grant waivers to exceed a state law limiting local add-on taxes, and these waivers are typically approved.

As California voters consider these significant tax proposals, the outcomes could reshape the financial landscape of the state’s largest urban centers and influence the future of public services.
