Can Virginia, Home to the World's Largest Data Center Market, Also Decarbonize Its Grid?

Data Center Growth in Virginia Raises Environmental Concerns

An unexpected move by Loudoun County, a Washington, D.C. suburb in Northern Virginia, sparked wide-ranging discussions in March. The region, which is known for hosting the world’s largest collection of data centers, denied a proposal to build a larger data center than what the existing zoning permits. This astounded many as the decision was later reversed, approving a smaller project version. However, the initial denial increased concerns about the rapid rise of data centers and its implications for Virginia’s ambitious carbon reduction objectives.

Virginia’s largest electric utility, Dominion Energy, predicts that data centers will be the primary driver of the state’s increasing energy demand over the next 15 years. Although Dominion is committed to decarbonizing its Virginia grid by 2045, in line with the Virginia Clean Economy Act, the utility’s long-range plan indicates the need for new natural gas plants to meet the demand. This has led environmental groups to question whether the state can achieve its zero-carbon goal given the data center industry’s rapid growth.

Data Centers’ Significant Presence in Virginia

For nearly three decades, data centers have been a staple in Virginia, particularly in Northern Virginia. Northern Virginia became an attractive location for data centers due to its proximity to the federal government and defense firms. The region, especially Ashburn in Loudoun County, quickly became the heart of the U.S. data center industry.

The Virginia government has welcomed the data center industry. Since 2010, the state has exempted data centers from sales and use tax for many of their key components, provided they meet certain criteria. Such incentives have significantly attracted data centers to the state. However, as more data centers set up shop in Virginia, concerns are rising. Residents in Loudoun and neighboring Prince William County have complained about continuous humming from the centers’ operations, while conservationists worry about their heavy water use and expanding footprint.

Data centers are power-intensive and require a constant flow of electricity. As the industry expands, more electricity is needed to meet the demand, prompting the construction of new power sources and transmission lines. Although many data center companies have been active in developing renewable energy, the industry’s rapid growth in Virginia poses a challenge for utilities.

The Environmental Debate Over Data Centers

Environmental groups have questioned the accuracy of Dominion’s forecasts, suggesting that the utility is overestimating future growth to justify the continued operation and construction of natural gas plants. Others point out that much of the expected demand comes from a very small number of companies. If these companies change their growth plans, the actual growth in Virginia could be significantly different from Dominion’s current estimates.

Despite these disagreements, there is little dispute that data centers’ electricity demand is soaring in the short term. Over 5.8 gigawatts of power will be needed by various new facilities by 2032, which has led many to call for smarter planning and optimized solutions. Meanwhile, the state’s Joint Legislative Audit and Review Commission has been tasked with assessing how the rise in power demand from data centers may impact Virginia’s transition from fossil fuels to renewables.

As tensions rise, the search for solutions may become more complicated. Multiple groups, including the Virginia chapter of the Sierra Club, have announced plans to form the Virginia Data Center Reform Coalition to impose tighter data center regulations. Despite the challenges, some believe that partnerships with the industry can lead to “win-win solutions”.

Mississippi River Faces Persistent Saltwater Intrusion, Region Seeks Long-Term Solutions



For the third consecutive year, the Mississippi River is experiencing significant saltwater intrusion, prompting local communities and environmental experts to search for sustainable solutions. This recurring issue arises as the river’s flow decreases, allowing saltwater to move upstream and threaten drinking water supplies. The U.S. Army Corps of Engineers is actively involved in addressing this problem, employing temporary measures like saltwater barriers to mitigate the impact on affected areas.



Saltwater infiltration poses serious risks to public health and agriculture, as freshwater sources become compromised. The situation is exacerbated by prolonged periods of drought, which have reduced freshwater flow in the Mississippi River. According to the National Weather Service, drought conditions have worsened due to climate change, increasing the frequency and severity of saltwater intrusion events.



Local authorities are collaborating with federal agencies to explore permanent solutions. Among the proposed strategies are enhanced levee systems and improved water management techniques. The U.S. Army Corps of Engineers is evaluating the feasibility of long-term infrastructure projects to prevent further saltwater encroachment. Additionally, community leaders are advocating for increased funding to support these initiatives and safeguard the region’s water resources.



The impact of saltwater intrusion extends beyond drinking water concerns, affecting local ecosystems and agricultural productivity. Farmers in the region have reported crop damage due to elevated salinity levels in irrigation water. The Natural Resources Conservation Service is working with farmers to implement adaptive practices, such as planting salt-tolerant crops and improving soil management techniques.



As the Mississippi River continues to face challenges from saltwater intrusion, stakeholders emphasize the importance of collaborative efforts and innovative solutions. The ongoing threat underscores the need for comprehensive planning and investment to protect one of America’s most vital waterways from the impacts of climate change and environmental stressors.



Environmental activists have raised concerns over the fossil fuel sector’s significant impact on COP29, the latest United Nations Climate Change Conference. Activists argue that the industry’s presence diverts focus from critical climate actions.



The conference, designed to promote global climate agreements, faces criticism for allowing fossil fuel companies to participate extensively. Environmental groups claim these companies undermine efforts to reduce carbon emissions and transition to renewable energy sources.



According to Climate Action Network, fossil fuel representatives have increased their lobbying activities, aiming to weaken climate policies. These industries allegedly influence negotiations, leading to watered-down commitments that fail to address the urgency of climate change effectively.



Experts suggest that the influence of these companies stems from financial contributions and longstanding relationships with decision-makers. Critics argue that this affects the conference’s ability to enforce meaningful climate change regulations.



During the event, several protests highlighted the need for transparency and a stronger focus on sustainable energy solutions. Activists are calling for increased participation of renewable energy stakeholders in future conferences.



The controversy surrounding fossil fuel involvement at COP29 underscores the ongoing challenge of balancing industrial interests with the global imperative to combat climate change.
