Around 35% of Maryland鈥檚 鈥渃lean energy鈥� in 2020 came from controversial renewable energy sources such as trash incinerators, landfills and woody debris burned in power plants and paper mills, according to a recent report.
After reviewing records from the Maryland Public Service Commission, an environmental advocacy group called the Public Employees for Environmental Responsibility (PEER) found that Maryland utility companies paid $36 million for 鈥渞enewable energy credits,鈥� or RECs, from trash incinerators, landfills and paper mills that burn black liquor and wood waste for energy.
Maryland set up the in 2004 to encourage a gradual transition to clean energy, requiring energy companies to subsidize solar, wind and other clean energy sources through purchasing a specific percentage of renewable energy credits every year or pay a fee. At least some must come from solar and wind produced in the state.
A renewable energy credit represents a given amount of electricity that has been generated from renewable energy sources. When companies produce that renewable power, they get RECs that they can sell to others. This means that a utility company producing energy from gas or coal can purchase renewable energy credits from out-of-state facilities to reach the state鈥檚 Renewable Energy Portfolio Standard.
In 2019, the General Assembly passed a measure that mandated the state to get half of its electricity from renewable energy sources by 2030.
At issue are some of the sources that are classified as clean energy under state law. Energy made from trash incinerators, poultry litter, food waste, paper mills and landfills are currently listed alongside wind and solar as a 鈥淭ier 1鈥� clean energy source by the state and qualify for state tax breaks. 鈥淏lack liquor,鈥� a byproduct of paper production, under the Renewable Energy Portfolio Standard last year.
Whenever Maryland utility companies purchase renewable energy credits, the cost trickles back down to the consumer, said Tim Whitehouse, the executive director of PEER. He contended that Marylanders paid more for dirty energy sources like biomass than clean energy sources like wind.
In 2020, the aggregate cost of a solar credit was around $66 and $8.56 for a wind credit, according to PEER’s report. The aggregate cost of a credit from paper facilities burning wood was $10.22 and $7.99 for an energy credit produced by trash incinerators.
Environmental advocates and several lawmakers argue that energy made from trash and biomass are 鈥渄irty鈥� sources of energy, as some of these facilities have bad environmental records and release methane, which traps 80 times more heat in the atmosphere than carbon dioxide over a 20-year period, which contributes to global warming.
Methane is produced in landfills when organic waste inside 鈥� such as food scraps and grass clippings 鈥� decomposes. Anaerobic digesters also produce methane by breaking down food or animal waste, but contains the gas rather than releasing it into the air like landfills do.
鈥淢aryland ratepayers should not be responsible for the failing finances of yesteryear鈥檚 dirty energy sources,鈥� Lily Hawkins, Maryland Organizer with Food & Water Watch, said in a statement. 鈥淢aryland needs to clean up its act and remove polluting energy sources from our state鈥檚 renewable portfolio standard.鈥�
, Maryland energy providers paid more than $129 million to buy renewable energy credits from 鈥渄irty鈥� energy facilities in Virginia and $60 million from companies in Maryland since 2008. The report also projects that between 2008 and 2030, Maryland will spend half a billion dollars subsidizing dirty energy sources under the state鈥檚 Renewable Energy Portfolio Standard.
鈥淢aryland could have invested a half a billion dollars into climate programs in Maryland that made a real difference to Maryland residents, but instead chose to subsidize dirty energy sources 鈥� many of which provide no energy to Maryland and is as bad or worse for the environment as fossil fuels and provide no jobs for Maryland residents,鈥� Whitehouse said in an interview.
This year, some lawmakers are taking steps to clean up the state鈥檚 Renewable Energy Portfolio Standard. Del. Vaughn Stewart (D-Montgomery) that would remove energy production from landfills, trash incinerators, burning wood, anaerobic digesters and animal waste from the state鈥檚 definition of clean energy that qualify for state tax breaks.
鈥淵ou have this perverse situation where every time you pay your Pepco bill, you鈥檙e actually paying more so that we can subsidize sources that the vast majority of experts would not consider clean or renewable, but we define that way in state law,鈥� Stewart said.
鈥淭his bill will once and for all turn off this pollutant spigot,鈥� he continued.
Stewart said the state鈥檚 current Renewable Energy Portfolio Standard is flawed because it subsidizes facilities that emit greenhouse gas emissions, which hampers the state鈥檚 climate goals and does not produce new jobs in Maryland since most of the renewable energy credits come from out-of-state facilities.
For instance, Maryland utility providers spent more than $26 million between 2014 and 2020 purchasing energy credits from a facility in Virginia that burns wood waste from logging operations to produce electricity for Virginians, according to PEER鈥檚 report. Virginia excluded biomass facilities as a renewable energy source in 2020, forcing the facility to sell its energy credits to states that accept it like Maryland, Whitehouse said.
While Maryland鈥檚 law requires power providers to purchase renewable energy credits from solar and wind companies operating in Maryland 鈥� which helps create state jobs 鈥� state law does not require the same for other industries. This means that operators like Virginia鈥檚 biomass facility can be subsidized without providing any direct benefit to Marylanders. State law also not require facilities producing energy credits to provide electricity to Maryland customers.
鈥淭here鈥檚 no oversight as to whether these companies have good [environmental] compliance records or whether there鈥檚 even any energy produced for the grid,鈥� Whitehouse said.
Sen. Michael Hough (R-Frederick) and six other senators from both sides of the aisle are that would remove trash-to-energy plants from the state鈥檚 Renewable Energy Portfolio Standard.
Hough has worked for years from two trash incinerators 鈥� one in the city of Baltimore operated and the other in Dickerson 鈥� from the state鈥檚 classification of clean energy that qualify for tax breaks. The Wheelabrator, Baltimore鈥檚 trash incinerator, is considered to be the biggest source of air pollution in the city by many experts.
But Hough鈥檚 efforts have faced political opposition in the past. Last year, Hough tried to attach an incinerator amendment to the bill that removed 鈥渂lack liquor鈥� from the state鈥檚 Renewable Energy Portfolio Standard, but to be attached to another bill.
