Department of Energy: Energy 101
The Department of Energy has produced a series of videos on YouTube titled Energy 101. In this series they touch on some relevant topics in the Energy Management field. We have compiled the videos here for your viewing.
In this edition of Energy 101, we discuss lighting choices. People have been using the same light bulb since Thomas Edison invented it about 130 years ago. Today, there are more lighting options in stores that will save you energy and money.
In this edition of Energy 101, we talk about Lumens. When you're shopping for light bulbs, compare lumens to be sure you're getting the amount of light, or level of brightness, you want.
Energy Efficient Data Centers
Data centers provide mission-critical computing functions vital to the daily operation of top U.S. economic, scientific, and technological organizations. These data centers consume large amounts of energy to run and maintain their computer systems, servers, and associated high-performance components—up to 3% of all U.S. electricity powers data centers. And as more information comes online, data centers will consume even more energy.
Data centers can become more energy efficient by incorporating features like power-saving "stand-by" modes, energy monitoring software, and efficient cooling systems instead of energy-intensive air conditioners. These and other efficiency improvements to data centers can produce significant energy savings, reduce the load on the electric grid, and help protect the nation by increasing the reliability of critical computer operations.
Geothermal Heat Pumps
The following edit was recommended by DOE's Office of Energy Efficiency and Renewable Energy's Geothermal Technologies Office: During the winter, the air is usually cooler than the temperature below ground. The solution circulates in a loop underground and absorbs the Earth's heat. This heat is brought to the surface and transferred to a heat pump. Ducts circulate the air to the various rooms.
An energy-efficient heating and cooling alternative, the geothermal heat pump system moves heat from the ground to a building (or from a building to the ground) through a series of flexible pipe "loops" containing water.
Energy Efficient Commercial Buildings
Learn how commercial buildings can incorporate whole-building design to save energy and money while enhancing performance and comfort. This video highlights several energy-saving features of the Research Support Facility at the Energy Department's National Renewable Energy Laboratory—a model for high-performance office building design.
Daylighting—the use of windows or skylights for natural lighting and temperature regulation—is one building strategy that can save money for homeowners and businesses. Highly efficient, strategically placed windows maximize the use of natural daylight in a building, lowering the need for artificial lighting without causing heating or cooling problems.
Concentrating Solar Power
From towers to dishes to linear mirrors to troughs, concentrating solar power (CSP) technologies reflect and collect solar heat to generate electricity. A single CSP plant can generate enough power for about 90,000 homes. This video explains what CSP is, how it works, and how systems like parabolic troughs produce renewable power.
See how wind turbines generate clean electricity from the power of wind. The video highlights the basic principles at work in wind turbines, and illustrates how the various components work to capture and convert wind energy to electricity. This updated version also includes information on the Energy Department's efforts to advance offshore wind power. Offshore wind energy footage courtesy of Vestas.
