Diphenhydramine (Benadryl) is the most common first-generation antihistamine found in OTC sleep aids, whether used alone or in combination with pain relievers, including acetaminophen (eg, Tylenol PM), ibuprofen (eg, Advil PM), and aspirin. Other sleep aids often contain the antihistamine doxylamine (eg, Unisom).
The output of a wind turbine depends on the turbine's size and the wind's speed through the rotor. An average onshore wind turbine with a capacity of 2.5â3 MW can produce more than 6 million kWh in a year â enough to supply 1,500 average EU households with electricity. An average offshore wind turbine of 3.6 MW can power more than 3,312 average EU households.
It is also one of the fastest growing electricity sources around the globe. In the United States alone, more than 13,000 megawatts of new capacity was installed in 2012, and by the year's end, there were enough wind turbines to power 15 million typical American homes -- without toxic pollutants or carbon emissions.
