The researchers focused on meeting each state's new power demands using only the renewable energies -- wind, solar, geothermal, hydroelectric, and tiny amounts of tidal and wave -- available to each state.They analyzed each state's sun exposure, and how many south-facing, non-shaded rooftops could accommodate solar panels.It's technically possible for each state to replace fossil fuel energy with entirely clean, renewable energy, experts say.A new report is the first to outline how each of the 50 states can achieve such a transition by 2050.The upfront cost of the changes would be significant, but wind and sunlight are free.So the overall cost spread over time would be roughly equal to the price of the fossil fuel infrastructure, maintenance and production, authors say."The main barriers are social, political and getting industries to change.One way to overcome the barriers is to inform people about what is possible," said Jacobson, who is also a senior fellow at the Stanford Woods Institute for the Environment and at the Precourt Institute for Energy.

The plan calls for virtually no new hydroelectric dams, but does account for energy gains from improving the efficiency of existing dams.
The report lays out individual roadmaps for each state to achieve an 80 percent transition by 2030, and a full conversion by 2050.
So the overall cost spread over time would be roughly equal to the price of the fossil fuel infrastructure, maintenance and production, authors say. Jacobson, a professor of civil and environmental engineering at Stanford, and colleagues, including U. Berkeley researcher Mark Delucchi, are the first to outline how each of the 50 states can achieve such a transition by 2050.
One potential way to combat ongoing climate change, eliminate air pollution mortality, create jobs and stabilize energy prices involves converting the world's entire energy infrastructure to run on clean, renewable energy. The 50 individual state plans call for aggressive changes to both infrastructure and the ways we currently consume energy, but indicate that the conversion is technically and economically possible through the wide-scale implementation of existing technologies.
Everyone is drinking, peering into their screens and swiping on the faces of strangers they may have sex with later that evening. “Ew, this guy has Dad bod,” a young woman says of a potential match, swiping left.
