Explore what would happen if we covered the Sahara Desert in solar panels, and the possibility of it solving our energy crisis.

—

Stretching over roughly nine million square kilometers and with sands reaching temperatures of up to 80° Celsius, the Sahara Desert receives about 22 million terawatt hours of energy from the Sun every year. That’s well over 100 times more energy than humanity consumes annually. So, could covering the desert with solar panels solve our energy problems? Dan Kwartler digs into the possibility.

A lot speaks for solar energy. It’s clean, renewable – and now even cheaper than energy from fossil fuels like coal or natural gas. Sounds pretty great, right? But it only makes up a tiny bit of global electricity production. Why don’t we use a lot more of it yet?

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way. Our new channel Planet A explores the shift towards an eco-friendly world — and challenges our ideas about what dealing with climate change means. We look at the big and the small: What we can do and how the system needs to change. Every Friday we’ll take a truly global look at how to get us out of this mess.

While some renewable energy sources — like the sun, the wind, and water — can easily be seen and/or felt, geothermal (or simply “thermal”) energy comes from a more enigmatic source: the heat far below the Earth’s crust. For more than 100 years, steam from below the Earth’s surface has been used to generate power. From electricity generated through geothermal power plants to district energy systems that heat and cool buildings using an underground network of pipes, this alternative energy source has big potential. Now that’s deep! Check out this video to learn more about how geothermal energy works.

Transcript:

Renewable Energy 101

If you’ve ever observed an erupting volcano or the geysers at Yellowstone National Park, you’ve seen geothermal energy in action.

The Earth’s crust is made of rocks and water. Deep below that is a layer of hot, molten rock called “magma,” which is even hotter than the sun’s surface. The heat just over six miles below the surface contains 50,000 times more energy than all the oil and natural gas resources in the world.

Releasing a small amount of that heat in the right way can create electricity. A well drilled a couple of miles deep can capture the rising hot water and steam. That steam spins a turbine and a generator produces electricity.

Geothermal is one of the least explored sources of renewable energy in the U.S., and most of us probably don’t spend much time thinking about it. But since it’s a pollution-free renewable source of energy that’s consistently reliable — at least it has been for the past 4.5 billion years — maybe we should!

About Green Mountain Energy: As the nation’s longest-serving renewable energy retailer, we’ve been on a mission to change the way power is made since 1997. By choosing our 100% clean, renewable wind and solar energy plans for their homes and businesses, Green Mountain customers have avoided more than 81 billion pounds of CO2 emissions to date — that’s like taking 8.6 million cars off the road for an entire year! But, we’re more than just an energy company. We’re helping our customers make a positive environmental impact, support a cleaner grid and green their carbon footprints with sustainable living solutions, renewable energy plans and the purchase of carbon offsets. And, our 501(c)(3) nonprofit organization, Green Mountain Energy Sun Club®, has donated more than million in grants to nonprofits for sustainability projects focused on renewable energy, energy efficiency, resource conservation and environmental stewardship. For more information, visit greenmountainenergy.com and gmesunclub.org. Together, we’re building a cleaner, greener tomorrow.

Every day, the world uses 93 million barrels of oil. Not only does this pollute the earth, but we’re running out of resources. Hydropower is the world’s oldest and most widely used renewable energy source but, what exactly is it?

More and more solar panels are popping up all over the world – and it’s easy to see why: They provide clean energy at falling prices. Awesome, right? Well actually, there are also some not-so-green sides to this technology. We’ll take a closer look at three big criticisms solar energy faces and check out just how much of a problem they are.

We’re destroying our environment at an alarming rate. But it doesn’t need to be this way.

Explore how wind turbines convert wind into electricity, and the challenges of powering the world entirely with wind energy.

—

Every 24 hours, wind generates enough kinetic energy to produce roughly 35 times more electricity than humanity uses each day. And unlike coal or oil, this resource is totally renewed each day. So how can we harness this incredible amount of energy, and is it possible to create a world powered entirely by wind? Rebecca Barthelmie and Sara Pryor dig into the science of wind turbine technology.

Lesson by Rebecca J. Barthelmie & Sara C. Pryor, directed by Gavin Edwards, Movult.

The potential of geothermal energy seems enormous. If estimates are correct, then the heat under our feet amounts to 50,000 times more power than all the oil and gas resources in the world. So why isn’t everybody using this renewable energy?
