An energy audit is an inspection and analysis of energy use and flows for energy conservation in a structure, process, or system intending to reduce energy input without negatively affecting output. Energy audits can determine specific opportunities for energy conservation and efficiency measures as well as determine cost-effective strategies ...
Logo for renewable energies (solar energy, bio-energy, energy of water, wind energy) by German graphic designer and art director Melanie Maecker-Tursun from Hamburg. German Logo für Erneuerbare Energien (Solarenergie, Bio-Energie, Energie des Wassers, Windenergie) der deutschen Grafikdesignerin und Artdirectorin Melanie Maecker-Tursun aus Hamburg.
Energy storage helps overcome barriers to intermittent renewable energy and is an important aspect of a sustainable energy system. [154] The most commonly used and available storage method is pumped-storage hydroelectricity , which requires locations with large differences in height and access to water. [ 154 ]

Energy conservation is the act of using energy in a more efficient and effective manner. While any form of energy may be conserved, electricity is the type most ...
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 ...
