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. 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.

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?

Nuclear Energy is a controversial subject. The pro- and anti-nuclear lobbies fight furiously, and it’s difficult to decide who is right. So we’re trying to clear up the issue – in this video we discuss how we got to where we are today, as the basis for discussion. Next week we’ll be looking at the arguments for and against nuclear power in detail.

Do we need nuclear energy to stop climate change? More and more voices from science, environmental activists and the press have been saying so in recent years – but this comes as a shock to those who are fighting against nuclear energy and the problems that come with it. So who is right? Well – it is complicated.

When you imagine the energy of the future, solar power is probably in the picture – but in recent years, less than 2% of the world’s electricity has come from solar power. Here are 5 new inventions that are likely to change that.
