APOD: 2017 September 2 - Milky Way Voyager

Poster Illustration Credit: NASA, JPL-Caltech, Voyager

Launched in 1977 on a tour of the outer planets of the Solar System, Voyager 1 and 2 have become the longest operating and most distant spacecraft from Earth. Nearly 16 light-hours from the Sun, Voyager 2 has reached the edge of the heliosphere, the realm defined by the influence of the solar wind and the Sun's magnetic field. Now humanity's first ambassador to the Milky Way, Voyager 1 is over 19 light-hours away, beyond the heliosphere in interstellar space. Celebrate the Voyagers' 40 year journey toward the stars with NASA on September 5.

Nearly 140 countries could be powered 100 percent by solar, wind, hydropower and geothermal energy by 2050, a group of researchers say.

Such a future could also mean a need for 42.5 percent less energy globally, because the efficiency of renewable sources, the scientists and engineers claim. In addition, this shift could lead to a net increase of roughly 24.3 million long-term full-time jobs, an annual decrease of up to 7 million deaths from air pollution annually, savings of more than $50 trillion in health and climate costs per year, and avoid 1.5 degrees Celsius of global warming, they say.

The cost? Only $125 trillion. (https://goo.gl/mk5dxV) _But as Rob Jordan of the Stanford Woods Institute for the Environment points out from the study, since sunshine and wind does not cost money, "the overall cost spread over time, including for operation, maintenance, transmission and storage, would be roughly equal to the direct price of the fossil fuel infrastructure."

Not only that, the renewable energy industry is a bonafide job provider—U.S. solar employs more workers than any other energy industry, including coal, oil and natural gas combined. Additionally, a recent study from the Lawrence Berkeley National Lab recent found that the U.S. wind and solar power boom helped prevent the premature deaths of thousands of people and saved the country billions of dollars in healthcare and climate-related costs in the years spanning 2007 through 2015.

As Jacobson said, "the beautiful part is that such a transition will also create over 20 million more permanent full-time jobs than lost worldwide, save consumers money and avoid over 3 percent of each country's GDP in air pollution health costs alone."
