Did you know that global warming is now considered a security threat? In the Wall Street Journal on June 26, Thomas Fingar, an analyst for the director of national intelligence, said environmental problems such as extreme weather, drought, flooding and disease are likely to create chaos in developing countries and have a severe impact on our nation’s infrastructure.

Nationally, we’ve all seen the television coverage of disastrous floods, tornados and hurricanes. In Michigan, we were lucky, but still had such severe storms that 51,000 people were without power in the tri-county area on June 26. Some lost power for the second or third time that month.

It might stretch the budget, but most of us can afford either a portable or standby backup generator. Two of the big names in standby residential generators are Generac, (888) GENERAC, www.generac.com; and Kohler, (800) 544-2444, www.kohlerpower.com.

Generac makes the Generac and Guardian lines. Prices for standby generators have gone down by about half over the past 10 years.

Generators are not “one size fits all.” You should contact a company with trained personnel to size, install and service it. Two names to consider for Generac are Joe Pizik Electric in Troy, (248) 362-2608, www.joepizikelectric.com; and Ziller Electric in Lake Orion, (248) 340-6000, www.zillerelectric.com.

Bratcher Electric in Wayne, (877) 722-0037, services and installs Kohler generators.
