Solar power gets its investment case laid out through the numbers Dutch broadcaster VPRO's Backlight team gathered in 2008: a patch of desert the size of France could meet current global energy demand, and manufacturers are already scaling up gigawatt production lines. Director Rob van Hattum follows the argument through Germany, where subsidies have pushed villagers to install panels on empty land and feed power stations directly into the grid, a model the film treats as proof the technology already works at scale. It tracks the same shift elsewhere, from a US Grand Solar Plan to French President Sarkozy's talks with Mediterranean governments about shared solar infrastructure, and includes Spanish electricity producers predicting that oil companies will eventually be squeezed out of the energy market entirely. Algae-fueled cars and rooftop solar leasing show up as signs of a market moving faster than public perception. The film's target is less the technology than the skepticism around it, cost, land use, efficiency, which it treats as outdated objections the industry has already answered.
