Geothermal energy uses the natural warmth below the surface of the Earth to heat water which can then be used to heat houses. It’s a clean and reliable. But, can there ever be enough buy-in to use it to radically change how we power our world?

Geothermal Energy Could Heat Homes And Reduce Our Dependence On Fossil Fuels | Mach | NBC News Video Rating: / 5
Geothermal power can revolutionize the way we see renewable electricity. It’s the only renewable source of energy that can produce a base-load of electricity 24/7. Geothermal has the potential to replace the world’s entire fossil fuel based electricity production. Video Rating: / 5

Could geothermal power be the future of electricity generation? Robert visits Cornwall to find out how Eden Geothermal are unlocking geothermal energy in the granite beneath the ground.
Their seriously impressive geothermal drilling rig might be the same kit you use to drill for oil and gas, but instead they are targeting clean, natural, sustainable energy from the rocks deep below. This is the first phase of a two well development which will completely power the eco-focused Eden Project making it carbon neutral as well as potentially power 17,000 surrounding houses.
What is really exciting about this project is that it feels like the beginning of a new geothermal energy industry could be on the horizon.

In the energy sector, wind energy is a breath of fresh air. But how does it all work? In this video, we explore how wind power is created by harnessing the power of Mother Nature herself and transforming it into clean, renewable energy. Even though human beings have been using the wind to power their technology for centuries, we have still only scratched the surface of what it can do. Learn how 20-story- tall turbines transform wind into electricity that makes up 4.1% of the United States’ energy each year. The answer to a clean energy solution is blowing in the wind. This video should provide some insights, and you can visit our website for more information!
Transcript:
Renewable Energy 101
We’ve been harnessing the wind since the ancient Egyptians used sailboats to travel, and windmills were used in agriculture in China over 2,000 years ago.
Americans were using wind turbines to produce electricity as early as the 1800s. You may have seen fields of turbines in wide-open spaces where you live since more than three-quarters of U.S. states produce wind energy on a large scale.
It may look small from a distance, but a modern turbine can be as tall as a 20-story building, with airplane wing-shaped blades that are as long as a football field. The blades spin at a slow speed — about one revolution every three seconds. A computer inside the box that sits at the top of the tower controls the direction of the blades to make sure they capture the most wind possible. The blades are connected to faster spinning gears inside the box that create kinetic energy. A generator converts that energy into electricity, which travels down the tower through a cable. The cable connects to the power grid that serves our communities.
See, all it takes is a little fresh air to make the turbines go around.

For Decades the wind turbine has been at the center of renewable energy generation. But the future of blade-less wind turbines is interesting, as it is poised to decentralized wind energy production. So what does solid state wind turbines look like, and what impact will they have? Let’s take a deeper dive!

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.

The truth about a wind turbine on your home. Get Surfshark VPN at https://surfshark.deals/undecided and enter promo code UNDECIDED for 83% off and 3 extra months for free! We’ve seen wind turbines popping up everywhere in the last few years for grid scale renewable energy installations. Solar panels for home has been a disruptive technology, but what if we could scale down wind turbines and install them on our home? In theory it sounds like a good idea to diversify our home power generation, but does it make sense to install micro wind turbines on your home vs. just installing solar panels? Let’s see if we can come to a decision on this.

Make your own wind turbine out of easy and cheap items. I found a motor and a windmill at a garage sale. This video will give you some ideas of how to put it all together.
The motor i used is AMETEK 124851 PERMANENT 40VDC MAGNET MOTOR WIND TURBINE GENERATOR 116123-03
Here is an ebay listing with this motor:

Geothermal technology is one of the most energy efficient ways to heat and cool your home. Installation methods allow almost any type or style of home to take advantage of geothermal heating and cooling. Whether its new construction or retrofit, installing geothermal could be right for you. Video Rating: / 5
Matt got the chance to meet up with Wade, a fellow builder in Rhode Island, who is in the process of installing a geothermal heating system at one of his projects. Geothermal heating systems have been around for much longer than you may think, and in theory are quite environmentally friendly and efficient. But due to a lack of consumer knowledge and the assumed complexity, geothermal still makes up a small fraction of HVAC systems used in America. But, as Wade and Lou (Wade’s HVAC installer) will tell us, these systems are more affordable than you think, and an excellent way to go about heating your house. There are a couple different types of geothermal heating systems, but essentially pipes in the ground circulate a water solution and extract heat energy and transfer it into buildings. If you are interested in learning more about this system, check out the video and listen to what Lou and Wade have to say!
