Finding money for home energy improvements is getting easier because many lending institutions now offer mortgages designed to cover the cost of energy upgrades.

Energy-efficient homes require less energy to heat and cool, so they are less affected by sudden spikes in energy prices. Because they consume less fossil fuel, energy-efficient homes also contribute less to global warming.

However, energy efficiency may come with a higher initial price tag ? whether it's a new home with the latest technology or an existing home remodeled with energy improvements, such as added insulation or a more efficient furnace. While most such homes eventually pay for themselves through lower energy bills, they might be difficult to afford initially, and that's where an Energy Efficient Mortgage (EEM) can help.

These mortgages help you purchase an energy-efficient new home or pay for energy upgrades to an existing home. EEMs are available through many government-insured loan programs and from conventional lenders. Energy Star, a government program that encourages energy efficiency, also is promoting these loans.

Brian Ng, the Energy Star for Homes Finance Coordinator, says EEMs have the potential to reduce a homeowner's bills. 'Say the energy improvements cost the homeowner an additional $20 a month in mortgage payment, but the improvements save $40 a month in utility bills. Thus, the improvements end up more than paying for themselves, the homeowner saves money and less energy is consumed,' Ng says.

To qualify for most EEMs, the home you're purchasing needs a certified energy evaluation to show that it's already energy efficient or to identify specific cost-effective improvements that should be made. Ng says this process benefits home buyers. 'They're not only getting additional money to pay for improvements, they're also getting assurance that the improvements actually will pay off in energy savings.'
