Question 1 Flashcards
(10 cards)
How do we generate electricity?
natural gas, renewable sources, coal, and nuclear energy
How do we use electricity?
for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems
From what sources do we generate most of our electricity in the US
fossil fuels, natural gas, coal, nuclear
what are the primary sources of electricity in your region of the US
natural gas and nuclear energy
How does a generator work
The force of the fluid on the blades spins (rotates) the rotor shaft of a generator. The generator, in turn, converts the mechanical (kinetic) energy of the rotor to electrical energy.
what are some ways we transform energy from one form to another
battery(electricity) (chemical energy → electrical energy) Electric generator (kinetic energy or mechanical work → electrical energy) Electric heater (electric energy → heat) Fire (chemical energy → heat and light)
how much of the electricity that is used in the US is gene rated by wind, solar, or other renewable energy?
Renewable energy generates over 20% of all U.S. electricity , and that percentage continues to grow.
How has this( how much of the electricity that is used in the US is gene rated by wind, solar, or other renewable energy?)changed over the last ten years?
In the decade analyzed by Climate Central, solar went from generating less than half a percent of the nation’s electricity to producing nearly 4%. In that same period, wind grew from 4% to roughly 10.
How do we move electricity from power plants to our homes
through a complex system, sometimes called the grid
what is distributed generation
Distributed generation (also called on-site generation or decentralized generation) is a term describing the generation of electricity for use on-site, rather than transmitting energy over the electric grid from a large, centralized facility (such as a coal-fired power plant).
