What if I told you there was an always-on, carbon free, renewable power source deep beneath the earth’s surface. Why haven’t we been using this power source, literally available under our feet, as much as possible? Let’s look at the explanation behind Geothermal energy and it’s challenges … one of which is a little … ground-breaking.

2.4 Introduction of Solar Photovoltaic Systems & Applications (Renewable Energy Technology)

Energy Efficiency No Comments »

The most useful way of harnessing solar energy is by directly converting it into DC electricity by means of solar photo-voltaic cells.
Photovoltaic comes from the words photo, meaning light, and volt, a measurement of electricity.
Photovoltaic cells are also called PV cells or solar cells for short.
The first practical PV cell was developed by Bell Telephone researchers.
At first, PV cells were used primarily in space to power U.S. space satellites. Now PV cells are common in many different applications.
Solar-powered toys, calculators, and many lighted roadside signs all use solar cells to convert sunlight into electricity.

What is Biomass? A Renewable Energy Source that Puts Organic Waste to Use

What is Biomass? A Renewable Energy Source that Puts Organic Waste to Use

Biomass explained: Learn how forest and agriculture “leftovers” are used to create renewable energy. Most US biomass power producers use byproducts as fuel for electricity – materials like rice hulls or tree tops and limbs that can’t be made into another product. Not only is biomass a carbon neutral form of electricity, it also reduces the abundant organic waste created from other industries.

Tidal energy could be huge – why isn't it?

Alternative Energy No Comments »

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.

Why This Liquid That Stores Solar Energy for Years Matters

Energy Efficiency No Comments »

Exploring why this liquid that stores solar energy for years matters. To start comparing quotes and simplify insurance-buying, check out Policygenius: https://policygenius.com/undecidedwithmatt Thanks to Policygenius for sponsoring this video! Storing solar energy cheaply and efficiently is a key component for the future of renewable energy. Even though lithium ion batteries are great for solar power, they can still be costly and, depending on the chemistry, there can be safety concerns. There are ways we can store solar energy more directly though … and one of those is heat. For instance, concentrated solar energy plants can use that heat for producing electricity, cement, steel, green hydrogen, or anything else that needs high temperatures. Or for storing that thermal energy for days. A recent breakthrough could allow us to store solar energy directly into a liquid for up to 18 years. How’s it work? And could this be a viable path forward for solar energy storage? Let’s see if we can come to a decision on this.

Why is FRANCE betting on NUCLEAR ENERGY again? – VisualPolitik EN

Alternative Energy No Comments »

Join the VisualPolitik community and support us on Patreon: https://www.patreon.com/VisualPolitik

In order to guarantee France’s electricity supply, become more competitive and achieve carbon neutrality by 2050, Emannuel Macron has just put France back in the race for nuclear development. The French nation, the country that is most dependent on nuclear energy, will build new reactors in the coming years. And that’s not all, it is also fighting hard for the European Union to consider nuclear as a green and sustainable energy.

In this video we tell you all the details about France’s recent bid to return to the atomic age.

Learn the positives and negatives of nuclear power.
In the ’70s people started getting excited about nuclear energy because it has the technology required to be used on a large scale.
In fact, nuclear energy accounts for roughly 21% of the electricity produced in the US.
Compare this to all of the other renewables like solar and wind which combined only produce 12%
But, nuclear power has a dark side

Czech Republic calls nuclear energy a 'priority' as it assumes EU Council Presidency | DW Business

Alternative Energy No Comments »

Nuclear power is getting more support on the EU-level as the Czech Republic assumes the EU Council Presidency. Leaders there say pushing up support for atomic energy is a priority. While countries like Germany, Denmark and Austria are saying goodbye to it, the Czech Republic, Slovakia and Poland (and also France) are focusing on expanding their nuclear energy.
