Conserving energy is not just an eco-friendly endeavor, but a potentially lucrative one as well. Homeowners and apartment dwellers alike who attempt to conserve energy may do so to promote the long-term health of the planet, but such efforts also greatly reduce energy bills. Thanks to air conditioning systems, energy bills might spike in summer. But winter utility bills also can be costly, especially in homes that have not been winterized or audited to ensure energy is not being wasted. Winterizing a home involves taking steps to conserve resources and save a little money along the way.
