Did you know that for the world to function as we know it, it needs different types of energy, but on many occasions this energy pollutes our planet a lot.
In this video we are going to learn about the types of energy that do not pollute called: Renewable Energies or Green Energies.
Although they are numerous, we are going to know the most used ones:
SOLAR ENERGY
HYDROELECTRIC ENERGY
WIND ENERGY
GEOTHERMAL ENERGY

An Amazing 250+ watts of continuous power from this Turgo Micro Hydro system. I travel to an off grid Yurt to meet Eric in Western North Carolina. He shows off his Micro Hydro Turgo install. This is making all the power he needs to run basic appliances like coffee maker, mini split air conditioner and lights. This setup has a coanda screen feeding 700 feet of 4 inch pvc pipe penstock. The head pressure is 57 feet of drop resulting in 25psi at the turgo. Eric has a few nozzle sizes that he is able to swap to for flow rate change in the creek. In the summer he is running a single 5/8″ nozzle making 250 watts all the time.

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

Over 7 billion people need energy to live but with fossil fuels in decline, how will we keep the lights on?
Fossil fuels are no longer the only, the best or even the cheapest solution to our energy demands. Mankind’s oldest solution may be the answer. to this problem. Our cavemen ancestors knew the benefit of bioenergy every time they kept warm by a wood fire.

We can use all sorts of organic matter and waste to help keep the lights on. We can use waste, residues, food waste and manufacturing by-products instead.
Our research at the European Bioenergy Research Institute (EBRI) is showing that this waste can become useful. It can be turned into clean, renewable energy – bioenergy.

EBRI conducts world-class bioenergy research ranging from fundamental research and development through to the deployment of innovative technologies. Our team of internationally-renowned researchers are focused on developing innovative methods of generating energy from biomass waste and residues.
