New Hampshire joined several other states in 2009 by requiring our electric utilities to offer customers a voluntary "green option." As the prime sponsor of this bill, Suzanne worked with other legislators and stakeholders, including the utilities and the Public Utilities Commission, to give electric customers a choice of paying a little more each month to have their utility purchase renewable energy on their behalf. Again, this is totally voluntary for rate payers and will appeal to those who care deeply about the consequences of burning fossil fuels and who can afford a little extra each month. The program will not kick in until a minimum number of customers sign up.
The utilities are to promote this program a monthly bill and on their websites.
