NREL Study shows US has enough renewable energy potential to be energy independent now
Solar photovoltaic energy is easily abundant and doable to cover all our use and then some. In MD alone, where I live, 23% of the entire state's consumption could come from existing rooftops, and 43% could come from utilities scaling up solar development projects on parking lots and other larger scale infrastructure. There is enough rural land to provide 10 times the current usage, and could easily make up the remaining 34% of demand. The cost of distributed rooftop solar is still $5.00/watt in the US vs around $2.25/watt in Germany. That has to change through further competition and demand.
