2. The owner […]

Energy and Atmosphere: Overview

Today, buildings cause large amount of pollution through their energy consumption.  Buildings consume about 68% of the electricity generated in the United States.  This electricity is not usually produced by “green” resources - most of the electricity is generated from using fossil fuels which further deplete our source of limited fossil fuels and also add […]
