DEEP Reminds Residents To Use Best Practices When Wood Burning for Heat During Winter
(HARTFORD)— Winter is here, and burning wood to keep a home warm is a long-standing tradition in New England. Depending on the source of the wood, wood burning can provide a cost-effective alternative to use of fossil fuels. But did you know that one old, inefficient wood stove can emit as much air pollution as five dirty, old diesel trucks? The Connecticut Department of Energy and Environmental Protection (DEEP) is urging residents to protect their health and that of their family, friends, and neighbors by employing “best burn” practices. Properly burning the correct type of wood limits exposure to wood smoke, which is a toxic air pollutant.

DEEP Reminds Residents and Visitors to Exercise Caution During Fall Wildfire Season
(HARFORD, CT) – The Connecticut Department of Energy and Environmental Protection (DEEP) reminds residents and visitors to our state that the typical fall wildfire season in Connecticut runs from October through the first widespread snowfall. During this period, dry weather and windy conditions, in combination with fallen leaves and increased sunlight reaching and warming the forest floor, can elevate the likelihood of a wildfire. Almost all wildfires are caused by humans and are therefore preventable. Maintaining awareness of fire danger and observing appropriate precautions are things that everyone can do to minimize the likelihood of starting a dangerous wildfire.
