What is Green Energy?
Solar
Even though a life-cycle analysis which
includes the heat energy necessary to manufacture solar panels
drives up solar’s carbon
footprint, it’s no where close to fossil fuels like oil and
coal. And sunshine is also a renewable resource safe from the vagaries
of global market price based on demand for finite resources like
fossil fuels and uranium. The solar energy industry is experiencing
more than 30% annual growth worldwide. In addition to the renewable
energy resources cited earlier, the U.S. Department of Energy explains
how the technology works and how its potential varies based on
location.
