The oceans, that cover most of the planet, are full of energy. So much, in fact, that if we could harness that of all the waves, we’d fulfill global demand three times over. There’s just one small problem: No one has figured out exactly how to make this work long-term. But we could be on the cusp of sea change.

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

Making clean energy isn’t enough: We also have to move it.

In the near future, the energy made in the US is going to be much greener. The country’s current goal is for solar plants alone to make nearly half of US electricity by 2050. But we can’t just build solar plants where coal and gas plants used to be. They have to be built where it’s… sunny. And wind turbines have to be built where it’s windy. The problem is, that’s not always where the people who need the power are.

The distance from energy source to energy need is about to get a lot bigger. And the US is going to need more high-voltage transmission lines. A lot more. As soon as possible. While solar plants can be built relatively fast, high-voltage transmission projects can take up to 10 years. So experts say we need to start proactively building them, right now.

This is the second of five videos we’re releasing on climate coverage this week. You can watch the first video on extreme heat 🌡 and what cities are doing to combat that here: https://youtu.be/ZQ6fSHr5TJg

And the third video on prescribed burns 🔥 for forests here: https://youtu.be/0o6ezu_h6iE

Sources and further reading:
Much of the map data in the piece comes from the Net-Zero America study out of Princeton University: https://netzeroamerica.princeton.edu/

This map from the US Energy Information Association is a good way to see what power plants and high-voltage power lines are near you (if you’re in the US): https://www.eia.gov/state/maps.php

Vermont Public Radio reported on the energy bottleneck we talk about in the very beginning of the video: https://www.vpr.org/vpr-news/2020-12-15/transmission-grid-bottlenecks-in-northeast-kingdom-stall-solar-development

And here’s more about that denied power plant from local Vermont TV station WCAX: https://www.wcax.com/content/news/Regulators-deny-Derby-solar-project-504867011.html

This other great study is what calculated how much renewable energy potential there is in just those 15 middle states: https://acore.org/wp-content/uploads/2020/04/Corporate-Demand-and-Transmission-January-2018.pdf

And if you want to get really into the details of how these lines work, I found the Edison Tech Center really helpful: https://edisontechcenter.org/wires.html

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.

Tidal power converts the energy from the natural rise and fall of the tides into electricity.

Student Energy is currently developing the Global Youth Energy Outlook, a global youth-led report that will engage 50,000 young people around the world in 2021 to gather their perspectives on energy. Want to take part? If you’re between 18-30, head to www.bit.ly/gyeo to complete the survey! You can win 0 cash prizes in each region, or a fully funded trip to the next International Student Energy Summit!

Student Energy is a global youth-led organization empowering the next generation of leaders who are accelerating the transition to a sustainable, equitable energy future. We work with a network of 50,000 young people from over 120 countries to build the knowledge, skills, and networks they need to take action on energy. Learn more at www.studentenergy.org
