QUICK SUMMARY What solar panels are

Medium that converts solar energy into electricity

History of solar panels and solar energy How they work

Solar energy excites electrons creating a current Current and voltage create power

GLOBAL CLIMATE CHANGE Major environmental issue caused by

increase in temperature and CO2 concentrations

Due to burning fossil fuels—unsustainable energy source

WORLD FOSSIL FUEL RESERVES AND PROJECTED DEPLETION
