Renewables Reports and Examples
DOE Solar Futures Study — 95% decarbonization of the electric grid achieved by 2035 without increasing electricity prices; Achieving decarbonization requires significant acceleration of clean energy deployment, which will employ as many as 500,000–1.5 million people in solar jobs by 2035.
Many references showing we can reliably power the US grid with renewables
US can supply 90-100% of needs with wind and solar, easily 100% if other renewable sources included

Communities that have committed to 100% renewable energy
So far: 59 Countries, 72 Cities, 63 Regions/States, 9 Utilities, 21 NonProfit/Educational/Public Institutions, totaling more than 1.8 billion people (and counting…) who have shifted or are committed to shifting within the next few decades to 100% renewable energy in at least one sector (e.g. electricity, transportation, heating/cooling).

In response to the argument that solar takes too much land area
Most analyses show that the US could fulfill all the nation’s energy use needs with solar using less than 0.6% of US land area; and, this can include building and home rooftop area and not just vacant land. That would be a total of 14 million acres. By contrast, coal has disturbed 9 million acres in the US, and produces less than 40% of US energy; i.e. solar has a smaller land footprint per unit of energy than coal. If we apply this just to Virginia, 0.6% of the land would be 160,000 acres. Half of this could be installed on suitable rooftops. That leaves 80,000 acres to place at airports and other suitable land areas – a reasonable amount. And this does not consider the fact that solar will get more efficient, and some of the renewable will be provided by wind, so that the full 160,000 acres in Virginia will not be needed.
