The following info was borrowed from the EPA website:
“Space heating is a major use of energy in buildings nationwide. Recent data suggest that space heating accounts for about 42 percent of energy use in U.S. residences and about 36 percent of energy use in U.S. commercial buildings.
Homeowners spend an estimated $73 billion or 29 percent of their total energy-related expenditures on space heating alone, whereas commercial buildings spend more than $27 billion or 15 percent annually. The dominant fuel used for space heating tends to be natural gas, however; some regions of the country use other fuels widely. For example, natural gas utilities tend not to serve most rural areas, and large parts of the Northeast do not have natural gas coverage. Many customers in these areas use heating oil or propane.
In 2010, space heating in the residential sector produced an estimated 324 million metric tons of carbon dioxide emissions, with commercial buildings adding an additional 161 million metric tons per year.
Requirements for heating systems depend on the size and complexity of the spaces that need to be heated.”
At Sonshine Development, LLC, we have designed all of our Solar Spot 7 Systems to have Zero Carbon Footprints and our Black Solar Tubing Converts Sunlight to Heat Energy without the use of any Fossil Fuels. Although we, at the present time are only concentrating on Heating Water, our Solar Spot 7 Systems can and will be used for “Space Heating” in Phase II of our R & D and Marketing Plan.
