The ocean’s waves are immensely powerful. Harnessing that energy for grid-scale electricity production would be a major boon to the clean energy industry, but building durable, powerful, and cost-effective wave energy converters has proven difficult. Now though, an influx of federal funding is helping many U.S. companies gear up to test their latest wave energy technologies, giving many in the industry hope that wave power will see massive growth over the next few decades.

Can Underwater Turbines Work? Tidal Power Explained. Try Audible for free for 30 days. Visit https://audible.com/undecided or text undecided to 500 500. With tidal power we don’t have to rely on building massive dams and waterways that disrupt the environment in order to capture that power. Even though visions of underwater bladed turbines might pop into your head, there’s some other technology that may surprise you … like an undulating membrane that produces electricity … or perhaps an underwater kite.

Solar power has exploded over the past 2 decades, and prices for solar panels have absolutely plummeted. But as great as solar is, it has a problem, they’re unless at night. But it’s always daytime somewhere, and we already have roads and fiber optic lines that span continents, so what if we built a worldwide power grid and solar network? Would it even be possible, what would it cost, and would it be worth it? I was so curious about this, that I decided to make a video, so let’s dive in. INSANE Plan Fixes Energy Crisis With a Worldwide Solar Network! Is It Possible To Build a World-Wide Solar Network?

Miles below the Earth’s surface, there’s enough thermal energy to power all of humanity for the foreseeable future. It’s called geothermal energy, and it’s poised to play an increasingly large role as a source of always available, renewable power. Now, there are a number of startups in the geothermal space, working to figure out how to access this heat in difficult to reach geographies, at a price point that makes sense. And it’s even gotten the attention of oil and gas industry giants, who are interested in greening their portfolios while sticking to their core competencies – extracting energy resources from deep within the Earth.

How Geothermal Energy Could Power The Future

It’s estimated that we could (practically) capture enough tidal energy to power all homes in the United States TWICE over – but we can only manage a tiny fraction of that right now. For a planet that is 70% water, why is this technology still so far behind other renewables? Are things about to change?

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.

Over the last two decades, the wind power industry has grown at a dizzying pace. (Fun fact: a single rotation from one of the world’s most powerful wind turbines can generate enough electricity to charge more than 1,400 cell phones.) Building off this exponential growth, Denmark’s climate minister Dan Jørgensen lays out his plan to end the country’s oil industry by 2050 and transition to a fossil-free future powered by wind energy.

Newberry Volcano — the largest volcano in the Pacific Northwest — is the site of an experiment that’s aiming for a breakthrough in geothermal energy.

The experiment is one small step in the high-risk, high-reward world of next generation
geothermal. The goal is to replace fossil fuels with this always-on, renewable energy. The challenge, however, is getting it to work.

Explore how geothermal energy— the heat in the Earth’s crust— is being used to create renewable electricity and power.

—

While the weather in Iceland is often cold, wet, and windy, a nearly endless supply of heat bubbles away below the surface. In fact, almost every building in the country is heated by geothermal energy in a process with virtually no carbon emissions. So how exactly does this renewable energy work? Jean-Baptiste P. Koehl explores the two primary models for harnessing the planet’s natural heat.

Lesson by Jean-Baptiste P. Koehl, directed by Charlotte Arene.

Perovskite solar cells might revolutionize how humans generate energy from sunlight.
https://brilliant.org/ElectricFuture
First 200 people get 20% off annual premium subscription.

In this video we’ll explore the world’s fastest improving new solar technology, and provide an exclusive peek inside the lab of a team working on this breakthrough material.

Imagine an inexpensive solution of perovskite crystals that can make a photovoltaic cell so thin, that just half a cup of liquid would be enough to power a house. A solar panel so lightweight, that it can be balanced atop a soap bubble. That is known as the holy grail of solar energy. So when will we see perovskite solar panels used for a solar power system for your home? Maybe sooner than you expect.

Currently, only 2% of global electricity comes from solar power. And 90% of that, comes from crystalline silicon-based solar panels, the dominant material technology.

While abundant, silicon has downsides related to efficiency, manufacturing complexity, and pollution that prevent it from being an absolute no brainer. Emerging thin films like perovskites present a bright future. Imagine solar cars like a solar tesla, solar yachts, or a solar plane.

Solar cell technologies can be classified into two categories, wafer-based or thin-film cells. Perovskites are the leading contender in emerging thin films. Topics covered in this video include applications, perovskite crystal structure, working principle of perovskite solar cells, efficiency limits, multi-junction solar cells, shockley-queisser limit, how solar works, solar simulator, band gap, manufacturing, vapor deposition, how solar panels are made, and the future of solar power.
