RENEWABLE VS. NONRENEWABLE ENERGY

RENEWABLE

• Obtained by natural sources
• Main sources are sunlight, wind, tides, and geothermal
• Can be replaced and used continuously without becoming depleted

SOLAR PANELS

• Solar modules use light energy (photons) from sun to generate electricity
• Majority of modules use wafer-based crystalline sillicon cells (thin-film based)

PROS

• Easily regenerated
• Not much pollution
• Available throughout the world
• Cheap
• Boost economic growth and increase job opportunities

SOURCES: NATURAL

• Wind power: US can produce 10X its energy with wind power.
• Solar power(sun): technology used are solar panels
• Geothermal energy: heated water and steam from earth to run power stations
• Biomass: uses of plant matter and animal waste to creat electricity
• Hydroelectric power: flowing water to move turbines to generate electricity

NONRENEWABLE

• Produces constant energy throughout the world
• Sources are fossile fuels

CONS

• Difficult to produce
• Technology used to trap energy is costly

CONS

• Produces harmful greenhouse gases (global warming)
• Once depleted, they can't be replaced

PROS

• Less pollution
• East to transport from one area to another
• Low cost
• Abundantly avaliable in different areas

SOURCES: FOSSIL FUELS

• Petroleum: extracted and turned into a variety of fuel sources
• Coal: composed of organic matter
• Natural gas: product of decomposition
• Nuclear power: u-235 ( type of uranium )
