From Chris Wood, editor, Casey Extraordinary Technology: Let me ask you a question…

How much was your electricity bill last month?

Mine was $124.

All things considered, it’s a good deal. It keeps my lights on. It keeps my food cold. It keeps my place at a comfortable temperature.

But the cost adds up over time.

The average American paid around $1,500 for electricity in 2015. Over a lifetime, this adds up to more than $100,000.

Now, imagine erasing this cost from your life… forever.

Imagine powering your house for free.

It sounds like a pipedream.

But free energy—or at least extremely cheap energy—is closer to reality than you think…

Today, more than one million homes and businesses in the U.S. use the sun’s power to help offset a large part of their electricity bills.

This is possible because when the sun shines on certain materials, the energy knocks electrons loose from the atoms in the material. This creates an electric current. The creation of this current is called the photovoltaic (PV) effect.

But the PV effect is just part of the story. To capture the energy from this current, you need a semiconductor device called a photovoltaic—or solar—cell.

Today, solar cells make up the solar panels on houses and buildings. Soon, you’ll find them in see-through windows. Eventually, we’ll be able to spray solar cells onto virtually any surface to help power cars, or let you charge your cell phone from your clothing.

And soon, entire houses will be able to run on solar energy alone thanks to batteries connected to solar installations. These batteries store excess energy and provide power at night, on shady days, or during storms. So you can use solar energy all the time. And the technology can be used around the world—even in remote places.

The promise of solar energy is huge. It reduces pollution… it can be generated anywhere the sun hits… it’s virtually cost-free once you have solar cells… and it’s unlimited. The sun beams down enough energy every hour to meet the world’s energy demands for an entire year.

Yet solar energy accounts for less than 1% of global electricity.

That means there’s massive growth potential.

The International Energy Agency predicts that solar energy will produce 16% of global electricity by 2050.

The German research organization Fraunhofer Society is even more optimistic. It thinks solar energy could increase to 40% of global electricity production by 2050.

In short, by getting into the right solar stocks right now, you could make huge profits.

Reeves’ Note: Chris recently put together a report about two of the most-promising solar companies in the world. Both are critical to unleash “free, unlimited, and instant and energy.” This revolutionary technology promises to grow the industry by 16,566% in the coming years…
