How Much Renewable Energy on the Eastern Shore?

Jan Plotczyk • October 12, 2021


To avoid the worst impacts of climate change, climate scientists agree that we must significantly reduce the use of fossil fuels and transition to the use of renewable energy sources ASAP — in the next few decades, if not sooner.

 

Thirty states plus Washington, D.C., have established targets for the percentage of renewable energy sold by utilities in their states. Called Renewable Energy Portfolio Standards (RPS) or Clean Energy Standards (CES), the specific targets and definitions differ from state to state. But the goal of the standards is the same: to diversify the states’ energy mix, to reduce emissions, and to promote economic development. The National Conference of State Legislatures estimates that “roughly half of the growth in U.S. renewable energy generation since the beginning of the 2000s can be attributed to state renewable energy requirements.” 

 

Renewable energy is from a source that is not depleted when used, such as wind or solar power. Hydroelectric power, biomass, and geothermal are also considered renewable sources of energy. Clean energy typically refers to sources of energy that have zero carbon emissions. The two categories often overlap.

 

Maryland’s RPS, enacted in 2004, initially required that 20% of energy in the state be from renewable sources by 2022. Since then, the targets have been raised several times. In 2019, the RPS was raised to 50% renewable by 2030 (14.5% of that from solar), and a goal of 100% renewable energy by 2040. There are additional goals for offshore wind: 400 megawatts by 2026 and 1,200 megawatts by 2030.




So, how much are the nine Eastern Shore counties contributing to Maryland’s renewable energy goals? There is a handy online tool, WeatherPower by Climate Central, that can show us how much solar and wind energy the counties generate.

 

Climate Central is an independent organization of scientists and journalists that surveys and conducts scientific research on climate change, and informs the public of key findings. Their WeatherPower tool estimates and predicts the amount of solar and wind energy generated per day by county or state. Solar estimates include both utility-scale and residential installations. A complete description of methodology is available on the website.

 

Common Sense retrieved solar power data from WeatherPower for each Eastern Shore county for a sunny day (Sept. 29) and a cloudy day (Oct. 6). Results are shown in the chart below.



Chart 1. Approximate Solar Electricity Generated in Eastern Shore Counties, on a Sunny Day and Cloudy Day.

Somerset County is the leading solar energy producer among Eastern Shore counties, producing approximately 440 megawatt-hours (MWH) of electricity on the sunny day studied, and 260 MWH on the cloudy day. Queen Anne’s and Wicomico counties were next, both with over 100 MWH on the sunny day, and 59 and 60 on the cloudy day. All the other counties generated less than 100 MWH on the sunny day and less than 30 on the cloudy day. (Caroline County did not have measurable solar energy production estimated.)

 

How much energy is this? Well, one megawatt-hour powers roughly 33 homes for a day. Somerset County’s 440 MWHs would power an estimated 13,600 homes for a day.




Another way to look at the generation of solar electricity is by the amount of carbon dioxide (CO2) avoided. This measurement estimates the number of metric tons of CO2 that would have been emitted on average by fossil-fuel power plants operating in the state to produce the same amount of electricity as generated from the sun.

 

How much is a metric ton of CO2? According to the MIT Climate Portal, a metric ton is roughly equivalent to a cube measuring 27 feet on each side, filled with CO2. And, yes, this literally weighs a ton, even though it may seem like a gas couldn’t possibly weigh that much.

 

Somerset County generated enough solar energy to avoid the emission of 148 metric tons of CO2, or 148 of our 27-foot cubes.

 

Once the amount of CO2 avoided is estimated, calculations can then be made of human-scale equivalents, like:

  • Car Miles — The number of miles an average car would need to be driven to emit the same amount of CO2 as in the 'CO2 Avoided' estimate. Somerset County saved the equivalent of 361,000 car miles — on one sunny day.
  • Trees Planted — The number of tree seedlings planted and grown for ten years that it would take to absorb the same amount of CO2 from the air as in the 'CO2 Avoided' estimate. Somerset County “planted” the equivalent of 2,460 trees by generating the solar energy it did.
  • Smartphones Charged — The number of typical smartphones that could be charged using the amount of electricity generated from the sun. Somerset County charged the equivalent of 40.3 million cell phones.

 

On Sept. 29, Somerset County ranked #4 among Maryland counties in generation of solar energy (Prince George’s was #1, Montgomery was #2, and Baltimore County was #3). Rankings can vary daily.

 

Maryland ranked #15 among all states in solar energy generation on Sept. 29. On our sunny day, Maryland generated 5,700 MWH of solar energy, for a total of 1,890 metric tons of CO2 avoided.

 

Only two Eastern Shore counties generate wind energy: Somerset and Talbot. Somerset County is, again, the leader on the Shore, having generated 4 MWH of wind energy on Sept. 29 and 3 MWH on Oct. 6. There was very little wind on both of these days, but nevertheless, over one metric ton of CO2 was avoided.

 

Most of Maryland’s wind energy generation is in the western part of the state, with 160 MWH generated by Garrett County on September 29. Maryland’s total for that day was 170 MWH.

 

Once the offshore wind farms are built in the Atlantic Ocean off Ocean City, however, Worcester County will account for quite a lot of wind energy. Ørsted, the developer of two wind farms off Ocean City (one approved and one proposed), estimates that Skipjack 1 (operational in 2026) will generate 120 MWH per day (enough to power 40,000 homes), and the proposed Skipjack 2 installation would generate 760 MWH (250,000 homes). US Wind, developer of the MarWin project (2025), predicts 270 MWH of wind energy will be generated daily (80,000 homes).

 

Maryland has set ambitious goals for renewable energy. There is just shy of two decades to build the infrastructure needed to meet Maryland’s target for 100% renewable energy by 2040 — hence, a need for haste.

Common Sense for the Eastern Shore

 Sparking alarm among housing advocates, social workers, and residents, Salisbury Mayor Randy Taylor has announced plans to gut Salisbury’s nationally recognized Housing First program, signaling a break from years of bipartisan progress on homelessness. Created in 2017 under then-Mayor Jacob Day, the initiative was designed around a simple but powerful principle: that stable, permanent housing must come first before residents can address problems with employment, health, or recovery. The program was designed to provide supportive housing for Salisbury’s most vulnerable residents — a model backed by decades of national data showing it reduces homelessness, saves taxpayer dollars, and lowers strain on emergency services. But under Taylor’s leadership, that vision appears to be ending. In a letter to residents, the City of Salisbury announced that the Housing First program will be shut down in 2027, in effect dismantling one of the city’s long-term programs to prevent homelessness. Taylor says he plans to “rebrand” the program as a temporary “gateway to supportive housing,” shifting focus away from permanent stability and toward short-term turnover. “We’re trying to help more people with the same amount of dollars,” Taylor said. Critics call that reasoning deeply flawed, and dangerous. Former Mayor Jacob Day, who helped launch the initiative, says that Housing First was always intended to be permanent supportive housing, not a revolving door. National studies show that when cities replace permanent housing programs with short-term placements, people end up right back on the streets, and that costs taxpayers more in emergency medical care, policing, and crisis intervention. Local advocates warn that Taylor’s move will undo years of progress. “This isn’t just a policy shift, it’s a step backward,” one social service worker said. “Housing First works because it’s humane and cost-effective. This administration is turning it into a revolving door to nowhere.” Even some community partners who agree the program needs better oversight say that Taylor is missing the point. Anthony Dickerson, Executive Director of Salisbury’s Christian Shelter, said the city should be reforming and strengthening its approach, not abandoning its foundation. Under Taylor’s proposal, participants could be limited to one or two years in housing before being pushed out, whether or not they’re ready. Advocates fear this change could push vulnerable residents back into instability, undoing the progress the city was once praised for. While Taylor touts his plan as a way to “help more people,” critics say it reflects a troubling pattern in his administration: cutting programs that work. For years, Salisbury’s Housing First initiative has symbolized compassion and evidence-based leadership and has stood as a rare example of a small city tackling homelessness with dignity and results. Now, as Taylor moves to end it, residents and advocates are asking a simple question: Why would a mayor tear down one of Salisbury’s most successful programs for helping people rebuild their lives?

On the first Monday of October, the Supreme Court began a new term, Term 2025 as it is officially called. The day also marked John Roberts’ 20 years as Chief Justice of what history will clearly record as the Roberts Court. Twenty years is a long time but at this point, Roberts is only the fourth longest serving Chief Justice in our history. John Marshall, the fourth and longest, served for 34 years, 152 days (1801–35). Roger Brooke Taney, served for 28 years, 198 days (1836–64). Melville Fuller, served 21 years, 269 days (1888 to 1910). John Roberts was originally nominated by George W. Bush to fill the seat held by the retiring Sandra Day O’Connor but, upon the unexpected death of William Rehnquist, Bush instead nominated Roberts to serve as Chief Justice. His nomination was greeted by enthusiasm and high hopes in many quarters. He was young, articulate, personable, and highly qualified, having had an impressive academic record, experience in the Reagan administration and the private bar, and service on the federal D.C. Court of Appeals for two years. His “balls and strikes” comment at his confirmation hearing struck many as suggesting judicial independence. He sounded as well very much like an institutionalist, having said at an early interview that “it would be good to have a commitment on the part of the Court to act as a Court.” Whatever else might be said 20 years later about the tenure of John Roberts as Chief Judge, the Supreme Court is no doubt much less popular and much more divisive today than it was on September 29, 2005, when he was sworn in as the 17th Chief Justice by Justice John Paul Stevens, then the Court’s most senior associate justice, and witnessed by his sponsor, George W. Bush. Gallup’s polling data shows popular support for the Court now at the lowest levels since they started measuring it. In July 2025, a Gallup poll found that, for the first time in the past quarter-century, fewer than 40% of Americans approved of the Supreme Court’s performance. According to Gallup, one major reason that approval of the Supreme Court has been lower is that its ratings have become increasingly split along party lines — the current 65-point gap in Republican (79%) and Democratic (14%) approval of the court is the largest ever. The legal scholar Rogers Smith wrote in The Annals of the American Academy of Political and Social Science in June, “Roberts’s tenure as Chief Justice has led to the opposite of what he has said he seeks to achieve. The American public now respects the Court less than ever and sees it as more political than ever.” These results signify more than simply a popularity poll because a Court without broad public support is a Court that will not have the same public respect upon which their most important decisions have historically depended. And, whatever the reasons for this development, it has happened on John Roberts’s watch. There is no better example of the current divisiveness on the Court than the remarkable string of “emergency” rulings on the Court’s so-called shadow docket since January 20. The extent of ideological and partisan differences has been sharp and extreme. The conservative majority’s votes have frequently been unexplained, leaving lower court judges to have to puzzle the decision’s meaning and leaving the public to suspect partisan influences. And the results of these shadow docket rulings have had enormous, sometimes catastrophic, consequences: Removing noncitizens to countries to which they had no ties or faced inhumane conditions Disqualifying transgender service members Firing probationary federal workers and independent agency heads Ending entire governmental departments and agencies without congressional approval Allowing the impounding of foreign aid funds appropriated by Congress Releasing reams of personal data to the Department of Government Efficiency Allowing immigration raids in California based on racial and ethnic profiling John Roberts has written many Supreme Court opinions in his 20 years as Chief Justice. At the 20-year mark, the most important, to the nation and to his legacy, will likely be his opinion in the Trump immunity case, which changed the balance of power among the branches of government, tipping heavily in the direction of presidential power. Trump v. United States (2024). In her dissent from his majority opinion in that case, Justice Sonia Sotomayor, joined by Justices Elena Kagan and Ketanji Brown Jackson, warned about the consequences of such a broad expansion of presidential power. “The Court effectively creates a law-free zone around the president,” upsetting the status quo that had existed since the nation’s founding and giving blanket permission for wrongdoing. “Let the president violate the law, let him exploit the trappings of his office for personal gain, let him use his official power for evil ends. In every use of official power, the president is now a king above the law.” Roberts claimed in his majority opinion that the “tone of chilling doom” in Sotomayor’s dissent was “wholly disproportionate” to what the ruling meant. However, Sotomayor’s words have proved prescient: the breadth of power that Trump and his administration have asserted in the months since he was sworn in for his second term has made plain how boundlessly they now interpret the reach of the presidency in the wake of the Roberts opinion. Despite the early “balls and strikes” comment, the assessment of John Roberts’ long term judicial record suggests something different as seen by several distinguished legal commentators from significantly different perspectives. As summarized by Lincoln Caplan, a senior research scholar at Yale Law School, in a new retrospective article on Robert’s 20-year tenure, “From his arrival on the Court until now, his leadership, votes, and opinions have mainly helped move the law and the nation far to the right. An analysis prepared by the political scientists Lee Epstein, Andrew Martin, and Kevin Quinn found that in major cases, the Roberts Court’s record is the most conservative of any Supreme Court in roughly a century.” “What Trump Means for John Roberts's Legacy,” Harvard Magazine , October 8, 2025. Steve Vladeck, Georgetown Law Center professor and a regularly incisive Court commentator, characterized the 20-year Roberts’ Court as follows: “The ensuing 20 years has featured a Court deciding quite a lot more than necessary — inserting itself into hot-button social issues earlier than necessary (if it was necessary at all); moving an array of previously settled statutory and constitutional understandings sharply to the right; and, over the past decade especially, running roughshod over all kinds of procedural norms that previously served to moderate many of the justices’ more extreme impulses.” “The Roberts Court Turns Twenty,” One First , September 29, 2025. In another remarkable new article by a widely respected conservative originalist, similar concerns about the present Court have very recently been expressed. Caleb Nelson, who teaches at the University of Virginia and is a former law clerk to Justice Clarence Thomas, has written that the text of the Constitution and the historical evidence surrounding it in fact grant Congress broad authority to shape the executive branch, including by putting limits on the president’s power to fire people. “Must Administrative Officers Serve at the President’s Pleasure?” Democracy Project, NYU LAW , September 29, 2025. When the First Congress confronted similar ambiguities in the meaning of the Constitution, asserts Nelson, “more than one member warned against interpreting the Constitution in the expectation that all presidents would have the sterling character of George Washington.” Nelson continues, “The current Supreme Court may likewise see itself as interpreting the Constitution for the ages, and perhaps some of the Justices take comfort in the idea that future presidents will not all have the character of Donald Trump. But the future is not guaranteed; a president bent on vengeful, destructive, and lawless behavior can do lasting damage to our norms and institutions.” John Christie was for many years a senior partner in a large Washington, D.C. law firm. He specialized in anti-trust litigation and developed a keen interest in the U.S. Supreme Court about which he lectures and writes.

If you’ve ever wondered just how slavishly loyal Rep. Andrew P. Harris (R-MD01) is to President Donald Trump, you can now put a number on it! Just consult the Republican National Platform Ratings. When you do, you will find that Rep. Harris has a very high overall score: 90.38%. He is the most aligned with the Trump/GOP platform among Maryland’s congressional representatives. No surprise there. Among all U.S. senators and representatives (using 2024 votes), Harris is 43rd most aligned. One might expect more from the chair of the right-wing Freedom Caucus. Harris scores at 90.38% aligned overall. His ratings by topic range from 82.98% to 100%. The topics refer to chapters in the platform: Defeat inflation and quickly bring down all prices. Seal the border and stop the migrant invasion. Build the greatest economy in history. Bring back the American Dream and make it affordable again for families, young people, and everyone. Protect American workers and farmers from unfair trade. Protect our Constitution and seniors. Cultivate great K-12 schools leading to great jobs and great lives for young people. Bring common sense to our government and renew the pillars of American civilization. Government of, by, and for the people. Return to peace through strength. Here are all Harris’s scores:

Several thousand people turned out on Oct. 18 in communities across the Eastern Shore to participate in the national “No Kings Day” protests, joining thousands of simultaneous events nationwide opposing the policies of President Trump’s administration. Demonstrations were held in Salisbury, Ocean City, Easton, Cambridge, Chestertown, and Centreville. These gatherings were part of a broader coalition effort that organizers say reflects frustration with the administration’s direction and a demand for renewed accountability and democracy. Participants across the Shore held signs and expressed concerns about immigration enforcement, executive power, and transparency in government. In jurisdictions that lean Republican and supported Trump in 2024, the rallies underscore a growing discrepancy between voting patterns and present activism. For example, in Queen Anne’s County — where the Trump vote was strong — residents joined the demonstration with statements of surprise at the turnout. Despite the scale of national mobilization, local organizers emphasized that the protest is rooted in community values of fairness, participation, and civic voice. One organizer on the Shore described the event as a reminder that “when people choose to show up, they remind their communities what democracy looks like.” Authorities reported no major disruptions during the Shore events, and police in some areas confirmed the rallies proceeded peacefully. For many in the region, the demonstrations mark an opening moment for more active civic engagement on the Shore, one that observers say could reshape local politics in counties historically seen as less partisan.

The Maryland Democratic Party has launched a statewide initiative, Contest Every Seat, that aims to recruit candidates to run for public office across all levels of government ahead of the 2026 elections. Party officials say the goal is to ensure voters in every district across Maryland have a choice on the ballot. The program will include outreach, training sessions, and support for prospective candidates considering campaigns for local, county, and state positions. “The effort is designed to encourage Marylanders who want to make change in their communities to step up and take action,” the party announced. Interested individuals can visit mddems.org/run for information about the application process and training opportunities. The Maryland Democratic Party said similar initiatives in past election cycles helped increase candidate recruitment in local and rural areas, including the Eastern Shore.

With the federal government now shut down for more than three weeks, Maryland is losing hundreds of thousands of dollars in revenue daily, a reflection of the state’s deep economic ties to the federal workforce. According to the Maryland Comptroller, approximately 230,000 Marylanders work directly for the federal government, with an additional 200,000 employed by federal contractors. The state’s economy, long intertwined with the operations of nearby federal agencies, is feeling the strain as paychecks stall and agencies close. Comptroller Brooke Lierman estimates Maryland is losing about $700,000 in state revenue each day — roughly one percent of the state’s average daily revenue of $100 million. “That is a small piece of our overall state budget,” Lierman said, “but as long as all our federal workers are paid what they are owed, that money will get back to us.” Federal employees generally receive back pay after shutdowns end, but recent statements from President Trump suggesting that furloughed workers may not be repaid have created uncertainty. More than 150 members of Congress, including Maryland’s entire Democratic delegation, signed a letter this week urging the Trump administration to guarantee back pay under the 2019 Government Employee Fair Treatment Act, which requires compensation for federal employees affected by a shutdown, and which Trump himself signed into law. Rep. Sarah Elfreth (D-MD03) said Congress is prepared to defend those protections. “Denying that pay would be illegal, and we will use every tool we have — both in Congress and in the courts — to ensure federal employees are made whole,” she said. During the 35-day federal shutdown in 2019, Maryland lost more than $13 million daily in economic activity and over $550,000 daily in tax revenue, according to state data. This latest shutdown comes amid broader federal workforce reductions under the U.S. Department of Government Efficiency, which announced layoffs earlier this year. A federal judge temporarily halted further cuts on Oct. 15 following a legal challenge. The effects extend beyond government offices. Universities such as Johns Hopkins and the University of Maryland Baltimore Washington Medical Center report disruptions to federally funded research projects and grant cycles. Gov. Wes Moore has directed state agencies to provide emergency support to furloughed federal workers, including housing and utility assistance. On Oct. 17, Moore announced the Maryland Transit Administration will offer free MARC and commuter bus rides to federal employees who show valid government ID. “This is what Maryland does in times of crisis, we band together and help each other out,” Moore said. “But no state can fill the gap created by the federal government. The longer this shutdown lasts, the more pain we will feel.” There is no indication of when negotiations in Washington to end the shutdown will resume.
