  • Cellar Ridge – Involved in New HomesTell Personal Story, How I got involved
  • The building sector uses the most electricity of any sector
  • Just about half of our energy in btu’s goes to building. 42% is operations.Buildings are the largest contributors to climate change – electricity is generated by coal, coal is the only fossil fuel plentiful enough to cause irreversible climate change.80% of U.S. Electricity CO2 Emissions Come From Coal.76% of This Electricity is Consumed by the Building Sector.Nation’s economy hinges on a healthy building sector – manufacture, installation, maintenance.Locally, Bonneville Dam cannot supply more energy
  • We choose how to renovateCarbon Neutral New Homes by 2030Equal amount of existing homes will be retrofitted to 60% of the averageAccording to Harvard: 46 million under insulated homes
