A Google offshoot called Dandelion will begin to promote geothermal energy for residential heating and cooling in the NE-United States. Motivation: 39% of CO2 emissions come from buildings, so here is a vast potential to bring these emissions down. “Geothermal” in this context means draining heat from low depths using u-shaped plastic pipes, buried in a back yard and use it as an input for a heat pumps. For this purpose a drilling method was developed to minimize the cost of installing the pipes.
Dandelion is seeking to cooperate with specialized installation companies and offer a financial package to homeowners, with monthly expenses lower than the common fossil fuel bill, without a down-payment. Typical cost picture: investment sum $20-25k or $160-180/month over 20 years, substituting $35k of 20 year oil cost and 110 ton CO2. For propane consumers, saving would amount to $63k/130 ton CO2 over 20 years.
