My wife and I need to remodel our house to help with the energy bills and we need to rewire the house so we do not wake up in a fire. The house was grandfathered in so the house has a fuse box instead of a breaker box.

You can go to the Catalog of Federal Domestic Assistance (CFDA) http://www.cfda.gov and Grants.gov http://www.grants.gov - these are two sites created by the federal government to provide transparency and information on grants. Browse through the listings and see if you can find any grant that would support home repairs.

Note though that home improvement grants are NOT given to just about every citizen -- otherwise, every single homeowner in America will have designer made homes because the government paid for home improvements. Home improvement grants are given to very poor seniors such as this grant:
