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
POSSIBLE SOLUTION
BENEFITS OF SOLAR ENERGY
EFFICIENCY OF PV CELLS
INCENTIVES FOR USING SOLAR PANELS
OTHER BENEFITS OF SOLAR PANELS Easy to maintain 20-30+ year lifespan Silent
OFF-GRID LIVING
MORE OFF-GRID LIVING
SOLAR PANELS USING GRID-TIED POWER
SOLAR POWER AS POWER SUPPLY
“Solar power could make a measurable worldwide contribution to the world’s power supply by the 2020 to 2030 time frame” (Hogan)
