"TRANSITIONING THE WORLD ENTIRELY FROM BUSINESS-AS-USUAL ENERGY TO CLEAN, RENEWABLE ENERGY SHOULD SUBSTANTIALLY REDUCE ENERGY NEEDS, REDUCE COSTS, CREATE JOBS, REDUCE AIR-POLLUTION MORTALITY, AND REDUCE GLOBAL WARMING."
Transitioning to wind, solar, and other sources of renewable energy could reduce annual greenhouse gas emissions by 30-60%.

A CLEAN FUTURE NOW COSTS LESS THAN A DIRTY ONE
“The cost of solar energy has dropped more than 80 percent since 2008, wind costs dropped more than 50 percent since 2008, and LED lighting costs dropped more than 90 percent since 2008.”

GLOBAL ENERGY CONSUMPTION
WHY DO WE CONTINUE TO PURSUE AND SUBSIDIZE NEW FOSSIL FUEL EXTRACTION WHEN RENEWABLES ARE COMPETITIVE IN TERMS OF THE ENERGY EXPENDED IN ORDER OBTAIN IT AS WELL AS PRICE?
"Fossil fuels emit more that just carbon dioxide when burned. Coal-fired plants singlehandedly generate 42% of dangerous mercury emissions in the United States, as well as two-thirds of U.S. sulfur dioxide emissions (which contribute to acid rain)... fossil fuel powered cars, trucks, and boats are the main contributors of poisonous carbon monoxide and nitrogen oxide, which produce smog (and respiratory illness)" - NRDC

Fossil Fuel Resources: Oil, Gas, and Coal
"TO AVOID 1.5C GLOBAL WARMING, WE MUST STOP AT LEAST 80% OF ALL ENERGY AND NON-ENERGY FOSSIL FUELS AND BIOFUEL EMISSIONS BY 2030 AND STOP 100% NO LATER THAN 2050.
Air pollution from these same sources kills 4–9 million people each year, and this damage will continue unless the sources of air pollution are eliminated... if the use of fossil fuels is not curtailed rapidly, rising demand for increasingly scarce fossil energy will lead to economic, social, and political instability, enhancing international conflict."

Comparing costs: net zero emissions, biodiversity conservation, current military expenditures, and global warming impacts
THE ESTIMATED COST TO REACH NET ZERO BY 2050 IS ROUGHLY TEN TIMES CHEAPER THAN THE COST OF INACTION.
"The world stands to lose close to 10% of total economic value by mid-century if climate change stays on the currently-anticipated trajectory... Among others, physical risks include property damage, disruption to trade due to climate shocks (eg, severe weather events such as storms, floods and droughts), and lost productivity due to rising average temperatures."

land area required for 100% renewable energy vs other land use
HOW MUCH SPACE WOULD IT TAKE TO POWER THE WORLD WITH RENEWABLE ENERGY ALONE?
only 0.6% of all global land and 0.1% of global oceans
