Q.
What if there are multiple kids in our house?
Good question - it wouldn't be fair to sign an agreement with one kid and leave the others out. In that case, make sure all the kids sign the agreement and then promise to put their share from the month aside, using a piggy bank or a savings jar. Then when they have saved up enough from energy savings, you can take everyone out for a treat! That way everyone can learn more about saving money and teamwork.
