The Daily Need

The power of the sun

In “Beyond the Light Switch,” a two-hour, two-part documentary series that is being broadcast on public television stations across the country, David Biello, energy and environment editor at Scientific American magazine, walks viewers through a series of scenarios that outline what the nation’s energy future might look like. What if America invests in carbon capture? Could we see a nuclear power renaissance? Is wind power possible? What is a super grid, anyway?

In this excerpt, Biello explains how solar panels work and concludes that solar energy might not cost as much as we think it does.
