Energy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less and better sources of energy for continuous service) or changing one's behavior to use less and better source of service (for example, by driving vehicles which consume renewable ...
Energy usage in transportation and residential sectors (about half of U.S. energy consumption) is largely controlled by individual domestic consumers. Commercial and industrial energy expenditures are determined by businesses entities and other facility managers. National energy policy has a significant effect on energy usage across all four ...
Solar energy technologies, such as solar water heaters, located on or near the buildings which they supply with energy, are a prime example of a soft energy technology.. In 1976, energy policy analyst Amory Lovins coined the term soft energy path to describe an alternative future where energy efficiency and appropriate renewable energy sources steadily replace a centralized energy system based ...
Here's what’s going on — and how to cut down your energy expenses. William Koblensky Varela. January 2, 2025 at 7:00 AM ‘Difficult decisions to keep the lights on’: A third of Americans ...
Energy efficiency refers to changes in equipment and behavior that result in increased energy services per unit of energy consumed, while behavioral changes that reduce energy use are often referred to as energy conservation. Energy intensity which measures energy consumption per Gross Domestic Product (GDP) is one indicator of energy efficiency.

The U.S. Department of Energy is improving residential codes by 30% by 2012, in an effort to move to net zero energy homes by 2020. The International Energy Conservation Code (IECC) embodies the goals of the DOE, increasing efficiency by 15% since its 2006 predecessor. The 2009 IECC requires that 50% of all permanent lamps be high efficacy ...
