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

Let your elected representatives and business and cultural leaders know that our Refuge and others like it all over the country deserve to be protected. They deserve our stewardship for the natural wonders they shelter, and because they provide refuge for people, too.

The Budget Deficit In a recent debate on closing Maryland’s budget deficit, Minority Leader Jason Buckel, a Republican delegate from Allegany County, made an important point: “The man upstairs has only been there for two, three years. I don’t blame him for our economic failures of the last 10,” referring to Democratic Gov. Wes Moore, who was elected in 2022. Ahead of the 2026 gubernatorial elections, Buckel’s comments highlight a key reality that many of his Republican colleagues seldom admit: It isn’t right to blame Gov. Moore for a budget deficit that has been brewing for years. Now projected at $3.3 billion, Maryland’s structural deficit is a problem that started long before Moore took office. In fact, it was first projected in 2017, during the tenure of former GOP Gov. Larry Hogan. This isn’t an opinion — it’s a fact that Buckel and other lawmakers, including Republican Del. Jefferson Ghrist, have bravely acknowledged. During that same debate, Ghrist remarked that the Department of Legislative Services had warned about this deficit throughout Hogan’s administration, yet he did little to address it. Ghrist pointed out that during Maryland’s “good years,” when the state received a flood of federal covid-19 relief dollars, spending spiraled without regard for long-term fiscal health. Hogan used these one-time federal funds to support ongoing programs, which masked the true state of Maryland’s finances and created an illusion of fiscal stability. Hogan continues to take credit for the “surplus” Maryland had in 2022 — even though experts repeatedly note it was caused by the influx of federal dollars during the pandemic. As Ghrist correctly observed, the lack of fiscal restraint and slow growth during the Hogan years laid the groundwork for the $3.3 billion structural deficit the state faces today. Indeed, Maryland’s economy has been stagnant since 2017, especially in comparison to its neighboring states, well before Moore took office. Compounding these challenges are President Donald Trump’s reckless layoffs and trade wars with our allies. Thousands of federal workers who live in Maryland are losing their jobs, which will cost the state hundreds of millions of dollars in lost revenue. Trump’s tariffs will also put an enormous strain on local businesses, including Eastern Shore farmers, who are now subject to up to 15% retaliatory tariffs on chicken, wheat, soybeans, corn, fruits, and vegetables. FY2026 Budget Considering this grim reality, Maryland’s lawmakers are making difficult, but necessary, decisions to shore up the state’s finances. Gov. Moore and state legislative leaders recently agreed to a budget that prioritizes expanding Maryland’s economy without raising taxes on most residents. In fact, 94% of Marylanders should see either a tax cut or no change at all to their income tax bill under the proposed agreement. Lawmakers also plan to cut government spending by the largest amount in 16 years, while at the same time making targeted investments in emerging industries, such as quantum computing and aerospace defense, so the state is less dependent on federal jobs. While the richest Marylanders might see their income taxes go up, it’s reasonable to ask someone making over $750,000 a year to pay $1,800 more to support law enforcement, strengthen our schools, and grow our economy. As for the proposed tax on data and IT services, these products aren’t subject to Maryland’s sales tax under current law. Maryland leaders want to modernize our tax code by levying a 3% sales tax on these products. Because they don’t raise income taxes on the majority of Marylanders and because state leaders are also cutting spending by billions, these ideas are fair. They’re also necessary after Gov. Hogan chose to kick the can down the road instead of addressing Maryland’s long-predicted deficit and now that Trump’s policies will lay off thousands of Marylanders and his tariffs will hurt our state. By making responsible choices now, Maryland leaders are putting the state on a path to long-term economic stability. Their decisions will help Maryland thrive, create jobs, and invest in the vital services that every resident relies on — without burdening hardworking families. I’m confident Maryland will emerge stronger, more resilient, and ready to lead in the industries of tomorrow. Elaine McNeil is chair of the Queen Anne’s Democratic Central Committee.

Among Donald Trump’s most recent targets is what he calls “rogue law firms.” At 6pm last Thursday, March 27, he issued an Executive Order (EO) aimed at my old law firm, WilmerHale, as one of those “rogue” firms. Approximately 15 hours later, the firm filed a 63-page complaint challenging the EO on multiple constitutional grounds. The EO is an “unprecedented assault on the bedrock principle that one should not be penalized for merely defending or prosecuting a lawsuit” and constitutes an “undisguised form of retaliation for representing clients and causes Trump disfavors.” And by 8pm on Friday, March 28, a little over 24 hours after the EO was first issued, a federal district court judge in Washington granted a request for a temporary restraining order, blocking key provisions of the EO from taking effect for now. In doing so, the Court found that “the retaliatory nature of the EO is clear from its face. There is no doubt that it chills speech and legal advocacy and qualifies as a constitutional harm.” The Executive Order The EO and a so-called “Fact Sheet” that went with it recites that the Administration is committed to addressing the significant risks associated with law firms, particularly so-called “Big Law” firms that engage in conduct detrimental to critical American interests. Wilmer Cutler Pickering Hale and Dorr LLP (WilmerHale) is yet another law firm said to have abandoned the legal profession’s highest ideals and abused its pro bono practice by engaging in activities that “undermine justice and the interests of the United States.” The specific examples offered in support of this conclusion: The EO asserts that WilmerHale “engages in obvious partisan representations to achieve political ends,” an apparent reference to the firm’s representation of Trump’s political opponents — namely the Democratic National Committee and the presidential campaigns of Joe Biden and Kamala Harris. The EO cites WilmerHale’s “egregious conduct” in “supporting efforts to discriminate on the basis of race,” an apparent reference to the firm’s representation of Harvard in the Students for Fair Admissions litigation. The EO accuses WilmerHale of “backing the obstruction of efforts to prevent illegal aliens from committing horrific crimes,” an apparent reference to the firm’s litigation related pro bono practice and successful challenges to immigration related policies. The EO accuses WilmerHale of “furthering the degradation of the quality of American elections,” an apparent reference to the film’s involvement in challenges to restrictive state voter-identification and voter-registration laws. The EO singles out certain current and former WilmerHale partners, including Robert Mueller, for special criticism by describing Mr. Mueller’s investigation as “one of the most partisan investigations in American history” and having “weaponized the prosecutorial power to suspend the democratic process and distort justice.” The EO then Revokes security clearances held by WilmerHale attorneys; Prohibits the federal government from hiring WilmerHale employees absent a special waiver; Orders a review and the possible termination of federal contracts with entities that do business with the firm; Calls for the withdrawal of government goods or services from the firm; and Calls for restrictions on the ability of WilmerHale employees to enter federal buildings (presumably including federal courthouses) and on their “engaging” with government employees. WilmerHale’s Complaint WilmerHale engaged Paul Clement, a former Solicitor General during the George W. Bush administration and a well-known advocate frequently representing conservative causes, to represent the firm in this matter. Assisted by some 15 WilmerHale litigators, the complaint names the Executive Office of the President and 48 other Departments, Commissions, and individual Officers in their official capacity as defendants. A variety of constitutional violations are alleged: The First Amendment protects the rights of WilmerHale and its clients to speak freely, and petition the courts and other government institutions without facing retaliation and discrimination by federal officials. The separation of powers limits the President’s role to enforcing the law and no statute or constitutional provision empowers him to unilaterally sanction WilmerHale in this manner. The EO flagrantly violates due process by imposing severe consequences without notice or an opportunity to be heard. The EO violates the right to counsel protected by the Fifth and Sixth Amendments and imposes unconstitutional conditions on federal contracts and expenditures. The complaint alleges that WilmerHale has already suffered irreparable damage in the 16 hours since the EO issued. The firm has been vilified by the most powerful person in the country as a “rogue law firm” that has “engaged in conduct detrimental to critical American interests. The EO will inevitable cause extensive, lasting damage to WilmerHale’s current and future business prospects. The harm to the firm’s reputation will negatively affect its ability to recruit and retain employees. Further Proceedings Temporary restraining orders constitute emergency relief upon a showing of likely success on the merits and irreparable harm were the temporary relief not entered. A later hearing will be held in order for the judge to determine whether a preliminary injunction should be issued preventing the government from executing the EO during the continued length of the litigation. Editorial Note: In light of the recent capitulation of several “Big Law” firms to the unreasonable and unconstitutional attacks by the Trump administration, WilmerHale is providing a blueprint for resistance as it fights back. More law firms need to be inspired by WilmerHale’s response to Trump’s demand for revenge on his so-called political enemies.

Tom Timberman was one of the founders of Common Sense for the Eastern Shore. Sadly, he died last month. He will be missed. Common Sense exists because of his leadership and inspiration. His vision was to provide factual and timely commentary and analysis on topics that concern people who live and work on Maryland's Eastern Shore, and to provide factual reporting to help readers shape their own lives. It was important to Tom, as it is today to the editorial board, for Common Sense to help voters to be aware of the effects — personal and local — of decisions made at the federal and state levels. Especially relevant now is this from our Mission Statement: “We seek an America responsive to its citizens and its constitution.” We reprint this tribute from Bill Flook, President of the Democratic Club of Kent County : Many of us were deeply saddened to learn of TomTimberman’s passing last week. It’s hard to believe that such a strong Democratic voice is gone. I worked with Tom for much of the past decade on many good projects promoting our values and activities, including helping on his campaign for County Commissioner, and I’ll particularly miss following his lead as Captain of the Dawn Patrol. Our group met most Saturday mornings for coffee and some good chat, before heading up to Dems HQ to set up the booth there. We’ll miss you, Tom!

After over 12 hours of debate over two days (and a whole circus from the other side), the Maryland House of Delegates has passed HB 350, this year's state budget, and sent it to the State Senate. This budget is a deal between House Democrats, Senate Democrats, and Governor Wes Moore. It faces our state's $3 billion deficit head-on not with fantasy math, but with real choices: smart cuts and fair new revenue. This is what grown-up governing looks like. How We Got Here: Maryland’s budget problems didn’t start overnight. Leaders began warning about a shortfall in 2017 when Governor Larry Hogan was in office. Hogan made our state budget bigger every year, but the legislature wasn’t allowed to move money around or make common-sense changes. By law, they could only make cuts. In 2020, Maryland voters changed that. Starting in 2023, lawmakers finally got full power to shape the budget, not just cut from it. Instead of fixing the problem, Governor Hogan used federal COVID relief to hide our fiscal instability. Then, before leaving office, he drained our state’s savings from $5.5 billion to $2.3 billion to boost his image. Today, we are facing a new fiscal arsonist. Donald Trump’s trade wars and cuts to federal programs hit Maryland hard. We have more federal jobs and agencies than any other state, so we felt it worse than most. A University of Maryland study says Trump’s tariffs alone could cost us $2 billion. Trump/Musk's policies caused over 30,000 people in Maryland to lose their jobs, offices to shut down, and promised investments to disappear. These federal cuts added another $300 million to our budget deficit. COVID relief gave us a short break and even created a fake surplus under Hogan, but that money is gone now. Meanwhile, housing, healthcare, and college prices have gone way up. The Trump–Musk White House is making it worse by cutting even more funding, eliminating research, and gutting the services we rely on. That’s why Maryland had to act. We needed a real plan to protect working people, fund our schools and hospitals, and keep our state strong. Why Cuts Were Needed Trump’s trade wars and cuts to federal agencies hit Maryland harder than any other state. A University of Maryland study says those tariffs alone could cost us $2 billion. That hurts real people: A chicken farmer on the Eastern Shore is paying 25% more for fertilizer. A dock worker in Baltimore has fewer ships to unload. A restaurant owner in Western Maryland can’t afford eggs and tomatoes. We’ve lost over 30,000 jobs. Offices have shut down. Promised investments disappeared. The decisions of the Trump/Musk administration added $300 million to our state deficit.

 The 2024 presidential election was over swiftly. The Associated Press called it at 5:34 am on Nov. 6, and by 8 am, President-elect Donald Trump was crowing about the “ historic mandate ” given to him by the American people. A “mandate”? Turns out not. Trump jumped to an early lead on election night, but in the following days, his lead diminished as mail-in and provisional ballots were counted. A Baltimore Banner article on Nov. 6 highlighted the “Trump shift” that had occurred in every political subdivision in Maryland, even in counties where Democrat Kamala Harris won. This shift described the increase in Trump support since his loss to President Joe Biden in 2020 . As of Nov. 6, the biggest Trump shift was an 8.1% increase in his support in red Cecil County, but there were also shifts in the central Maryland counties that are the state’s Democratic strongholds — 4.3% in Montgomery and lesser amounts in other blue counties. Fourteen counties recorded shifts of 4% or more. On the Eastern Shore, every county had a shift over 4.5% except Talbot (2.7%), and the five largest shifts were Shore counties. For the state’s Democrats, it did not look encouraging. But as mail-in and provisional ballots were counted across the state, the Trump shift was reduced everywhere, and as of Nov. 16, disappeared altogether in Garrett (-1.2%) and Charles (-0.1%) counties. The shift dropped below 3% in all Maryland counties. Cecil’s shift became 2.1%. Montgomery’s shift dropped to 2.9%. Talbot’s shift declined to 0.2%, lowest of the Eastern Shore counties. Now, instead of five, only two of the highest five shifts were in Eastern Shore counties. The red bars in the chart below represent the Trump shift percentage values as of Nov. 16, in ascending order. The grey bars represent the misleading (and ephemeral) Trump shift percentage values as of Nov. 6. Please note the degree to which the Trump shift lessened and disappeared in the 10 days after the election. Another red mirage. But if you had only read the Nov. 6 article and not looked at the updated data, you would have been fooled into thinking Trump support is stronger than it is.
