Renewable energy heating and cooling is worth the cost in many ways.

First, many people consider protecting the environment worth the cost.

Second, federal and state governments, many utility companies, and others are offering significant rebates, tax credits and other incentives to encourage people to install renewable energy heating and cooling systems.

Third, the very significant savings achieved in heating and cooling costs will pay for the system over a period of a few years.

Finally, the renewable energy systems used to provide heating and cooling also can frequently be used to provide power for other devices.
