Three good reasons to incorporate alternative energy into your home design:
(1) Lower energy costs, often by 30-50%. In some cases, you can even sell surplus energy back to the grid. Imagine the power company sending you a check instead of a bill!
(2) Lower your carbon footprint. We all want to do our part to care for our environment; this is your opportunity.
(3) The government is eager to help in the form of tax credits available to help offset your costs. See these pages:

Radiant energy
Radiant energy systems avoid the air quality issues associated with forced air heating. Linked to geothermal systems, they use the temperature of the earth to help regulate the temperature of your home.

Fuel cells
Fuel cells convert natural gas to electricity. The by product of this cutting-edge technology is pure clean hot water.
