Earth Day (April 22nd) Ocean Power What you should know: The movement of water generates large amounts of energy. Electricity can be produced from the power of waves, tides, ocean currents, and free-flowing water in rivers and channels. A number of different technologies are currently being designed and tested to harness this power. The Department of Energy established a research and development program for marine and hydrokinetic technologies in 2008 to promote development of these technologies and understand better how our nations vast water power resource may contribute to our energy future. . Earth Day (April 22nd) Smart Electric Grid What you should know: The Smart Grid is like a sophisticated superhighway for electron that will: Allow us to more efficiently move wind energy from Montana to power an air conditioner in Missouri, for example. Help avoid costly brownouts by instantaneously rerouting electricity around a downed power line, or diverting excess power to a place experiencing high demand on a hot summer day. Foster a significant expansion of intermittent renewable energy such as wind and solar energy, because the Smart Grid will make it easier to store energy or reroute power from another source if the wind stops blowing or a cloud rolls over a solar array. Most importantly, empower consumers to save money on utility bills by giving you more information and greater control over your energy use. Someday soon, you might even use your wireless cell phone to program your plug-in electric vehicle to charge its battery at night when electricity rates are lowest, and then sell back a portion of that charge to the power grid during the day when rates are highest. * Earth Day (April 22nd) This is a picture of an energy efficient home, cut open to show its many different features and appliances. This scene describes what you can do to increase the energy efficiency of your home. It contains information about efficient appliances in general, air conditioners,
