Infrasound

Has anyone got any research data or articles or studies on infrasound and wind turbines ?  Is it a coincidence wind developers compare turbine sound with refrigerators ? ...................................http://www.scotland.gov.uk/Resource/Doc/158512/0042973.pdf

    Does this sound correct : 

    Massachusetts Renewable Energy Credit Problem
     
    Massachusetts officials thought the stalled offshore wind would accelerate their renewable program, so they increased the percentage of renewables that "investor-owned utilities" must offer by the standard offer from 1 % to 2%, which will now send  Renewable Energy Credits through the roof.
    Massachusetts has committed to a clean energy plan of being 80% carbon-free by 2050.
     
    The plan is called the Renewable Energy Portfolio Standard, RPS. The plan started in 2003 requiring a 1 percent increase per year of a utility's portfolio to come from renewable energy. New legislation doubled the requirement to increase 2 percent per year starting in 2020. As of 2018, the percentage was 13 percent. 
     
    The Renewable Energy Portfolio Standard, RPS only applies to "Investor Owned Utilities" which are well-known in Massachusetts. There are over 40 Municipal Electric Utilities that serve up to 50 towns that don't have to purchase renewable energy credits and there are no requirements for up to 15 percent of these town utilities. 
     
    Class I RECs are generated by renewable energy facilities in New England that began operation after 1997 and create electricity from solar photovoltaic (PV), solar thermal, wind, small hydro, aerobic digester gas, geothermal, landfill methane, marine energy, and biomass fuel. In addition non-emitting resources such as the stalled large hydro from Canada transmission project contracted by the state’s electric distribution companies from a 2017 solicitation. 
     
    The Canada hydro project has taken longer than expected to begin construction and in the meantime, "Investor Owned Utilities" must use Class 1 RECs to fill the void, or pay the CEC ACP which is equal to 50% of that of the Class 1 REC ACP. In 2021, that’s 50% of $60, or $30 and in 2022, that’s 50% of $40, or $20. This serves to tighten the Class 1 REC market to some extent, although when pricing is above the CEC ACP, Class 1 RECs will not be used. 
     
    Any Retail Electricity Supplier that is required to comply with the Massachusetts RPS and APS regulations may, if necessary, discharge some or all of its obligations by making an Alternative Compliance Payment (ACP) in the appropriate amount to the Massachusetts Clean Energy Center (MassCEC).
     
    The Massachusetts electric ratepayer never gets a break?
