Wise ways we use electricity Research on new and exciting opportunities to save money and reduce emissions with electricity is important. Here are some cleaner, greener ways electricity is used. Energy storage Although sunlight and wind are clean and renewable sources of electricity, they don’t produce any power when it gets dark or the wind stops blowing. By keeping that energy in different types of batteries, we can release this stored energy later, when we need it most. Pumped hydropower is a system that uses excess electricity to pump water uphill to a reservoir that acts like a battery. When electricity is needed, the water is released from the reservoir to flow downhill through turbines which generates electricity. Electric cars LED bulbs We have the option to drive cars that use electricity instead of a car that uses gas. We can charge those vehicles when the wind blows and the sun shines and store that electricity until we need to drive the car. Energy efficient bulbs reduce the amount of electricity it takes to light our homes. That’s because LED (light emitting diodes) bulbs transfer much more of the electricity they use into light than other bulbs. They use 90% less energy than incandescent bulbs for the same amount of light, and half as much as compact fluorescents. On top of that, an LED bulb will last much longer than the other bulbs. Heat pumps help heat and cool your home by moving heat energy to and from the air rather than using natural gas or other fuels to keep your home comfortable. Heat pumps can deliver 1 to 4 times more heat energy to a home than they consume. What else can we do to use electricity wisely? 6 - Colorado Agriculture in the Classroom
