46:10 Clean energy is becoming less exotic and more practical than ever before thanks to the efforts of a few key countries. Collectively, they’re greasing the wheels for a worldwide revolution. The Breakthrough in Renewable Energy, a new documentary produced by the acclaimed VPRO Backlight series, takes us inside the corporate offices and production lines where this groundbreaking work is being done, and examines what it could mean for the future of energy consumption on Earth.
What main factor will ultimately determine the widespread acceptance and use of solar and wind energy? In a word: cost. Once upon a time, investments in these alternative energy sources were considered an extremely risky proposition. After all, the cost to the consumers was many times that of energy powered by natural gas and other traditional fossil fuels. However, as argued by the film’s impressive panel of expert industrialists and other energy entrepreneurs, new and untested technologies are always priced high on the outset. Once the research, innovation and production of these technologies begin to progress and mature, the costs go down. This is where the industry stands today.
