<P> An October 2008 study conducted by the University of California at Santa Barbara for the National Bureau of Economic Research found that the 2006 DST adoption in Indiana increased energy consumption in Indiana by an average of 1% . Although consumption for lighting dropped as a result of the DST adoption, consumption for heating and cooling increased by 2% to 4% . The cost to the average Indiana household of the DST adoption was determined to be $3.29 per year, for an aggregate cost of $1.7 million to $5.5 million per year . </P> <P> Under the Standard Time Act of 1918, as amended by the Uniform Time Act of 1966, moving a state or an area within a state from one time zone to another requires a regulation issued by DOT . The governor or state legislature may initiate a request for the state or any part of the state; the highest elected officials in the county may make a request for that county . The standard in the statute for such decisions is the convenience of commerce in that area . The convenience of commerce is defined broadly to consider such circumstances as the shipment of goods within the community; the origin of television and radio broadcasts; the areas where most residents work, attend school, worship, or receive health care; the location of airports, railway, and bus stations; and the major elements of the community's economy . </P> <P> After receiving a request for altering a time zone, DOT determines whether it meets the requirement of minimum statutory criteria before issuing a notice of proposed rulemaking, soliciting public comment and scheduling a public hearing . Usually the hearing is held in the area requesting the change so that all affected parties can be represented . After the close of the comment period, the comments are reviewed and appropriate final action taken . If the Secretary agrees that the statutory requirement has been met, the change is instituted, usually at the next changeover to or from DST . </P> <P> Under the Uniform Time Act, moving an area on or off DST is accomplished through legal action at the state level . Some states require legislation while others require executive action such as a governor's executive order . Information on procedures required in a specific state may be obtained from that state's legislature or governor's office . Although it may exempt itself, if a state decides to observe DST, the dates of observance must comply with federal legislation . </P>
