As with most energy and cost efficient power alternatives, there’s a lot of misinformation surrounding solar energy — even when we’re faced with hard facts outlining their benefits. Consider the fact that it took nearly 30 years for fluorescent light bulb (also known as CFL) sales and dependency to rise, as Americans were unwilling to switch over from incandescent bulbs until 2010.

Tried and true sustainable products often sit on the market for a while before they become “trendy enough” to be purchased. But now, thanks to some promising developments from Tesla,(including some slicker-than-expected solar panel roofs) the value and importance of solar power is finally getting the momentum it so critically needs.

These moves are important because, not only is solar power cost effective, it reduces our reliance on fossil fuels, which is an imperative issue we need to tackle. Humanity’s current net emission is 37 gigatonnes of CO₂, meaning we’ll need a reduction of at least 700 gigatonnes to keep global warming within safe limits.

By switching over to solar power, we reduce our carbon dioxide emissions by over 37 million metric tons. And while it might be hard to see past your own finances, switching to solar power saves the United States over $400 billion in healthcare and environmental cleanup costs. But back to your wallet: solar panels pay for themselves in six to 15 years and increase the resale value of a house by about $15,000.

But solar power technology is nothing new. In fact, a similar standard of today’s models has been around since the 1960s. And since that time, panels have only become more efficient, more dynamic, and more attractive. So, what’s taken us so long to consider the switch?
