    The largest part of residential energy consumption (generally considered around 40%) maintains interior comfort regardless of the weather. Energy used to create this comfort is a function of how well inside is separated from outside. The separation zone, or "thermal shell", is the insulating layer around conditioned interior space.

    When a company produces 150 tons of food waste every day that is either a huge problem or a great opportunity to innovate and produce energy. Grocery stores, restaurants, sports arenas, schools, and hospitals in the U.S. generate an average of two tons - 4,000 pounds - of food waste per week. An estimated 35 million tons of food waste from commercial and residential sources end up in U.S. landfills each year, according to the U.S. Environmental Protection Agency.

    According to the National Lighting Bureau, poor lighting conditions cause the productivity levels of your employees to fall by 5% and can even lead to physical stressors like eyestrain, blurred vision, and headaches. Increasing light levels while decreasing your energy consumption will not only take care of your employees by making them more productive but it will also maximize your profitability by cutting your energy bill by as much as 40%.

    A few years ago, the smart grid industry had almost entirely written off the in-home display (IHD) for energy management. Several companies had introduced products that were pulled from shelves shortly thereafter due to poor sales. Media coverage pointed to high costs, complicated hardware, and low adoption rates as the downfall of these systems.
