How much cheaper does solar need to get? While solar has been becoming much cheaper, how far off are we from it being viable for everyone all over the world? Here's an excerpt from a compelling article...Australia definitely ahead of this curve in terms of viability though:
It's easy to get ridiculously excited about solar power these days. The panels keep getting cheaper as technology improves. Large photovoltaic arrays are sprouting up around the globe. Sure, solar still produces only 1 percent of the world's electricity, but it's growing at double-digit rates each year.
So with all this momentum, you'd think the solar industry could kick back and celebrate, right? Domination is only a matter of time!
Well … not so fast. A provocative recent essay in Nature Energy by two solar analysts, Varun Sivaram and Shayle Kann, argues that solar still has some hard economic obstacles to overcome before it can become a major energy source and provide (let's say) one-third of our power. Overcoming these hurdles could mean the difference between solar leveling off as a niche technology and solar taking over the world.
