Coal Keeps the Lights On? How to make light without it!

Sure, the Sun is Great, but we need lights at Night too… 25% of the world’s population doesn’t have access to electricity. Electrification is the greatest engineering achievement of the 20 th century. Half of India’s households lack electricity. How would your life change without it?

Coal can keep the lights on, but what is the cost? you/affect/coal.html you/affect/coal.html Q Q k k ZU ZU Do

How do you think a coal fired power plant works? How does that coal become electricity? energy/generating-electricity/coal-fired- how.asp energy/generating-electricity/coal-fired- how.asp phy.org/energy/power/elect_phy/flash/power plant_make_e.html phy.org/energy/power/elect_phy/flash/power plant_make_e.html

What are other ways people make electricity? How are these ways different from the way coal becomes electricity? How are they similar?
