Energy Sources 101: These Short Videos Explain the Basics

Published

on

If you’ve ever searched online for unbiased and fact-driven articles on energy, you’ve probably noticed that they can be quite rare. Almost every information source seems to be pushing an agenda.

Energy is a touchy subject, and billions of dollars are spent each year to campaign on issues surrounding fossil fuels, renewable energy funding, pipelines, environmental concerns, and fracking.

With so much at stake, special interest groups, governments, and corporations are constantly engaged to “win the war” on information by putting their own spin on facts. This creates a tangled web that is tough to navigate for any inquisitive person.

Energy Sources 101

Well, we have good news – recently, we came across a pretty nifty Youtube channel that is visual, intuitive, and fact-driven. It focuses on providing introductory information on different energy sources.

The Student Energy Movement aims to be a “universal entry point for learning about the energy system” by delivering accurate and unbiased energy information. Here’s some of the videos we thought were worthwhile, highlighting both the pros and cons of different energy sources:

Hydro

Explains how hydro power works, but also touches on pumped hydro (energy storage) and pros/cons.

Nuclear

The difference between fission and fusion, as well as the benefits and drawbacks of nuclear energy.

Oil

Explains how oil is formed, and also how it is processed and transported.

Natural Gas

Explains wet and dry gas, as well as how gas is extracted and processed.

Solar

Discusses both photovoltaic and solar thermal. For more information on how each of those types work, go here and here.

Also, here’s links to additional videos on energy sources such as geothermal, biofuels, coal, wind, and tidal.

Other Energy Topics

But that’s not all – the organization has also produced great videos on topics like fracking, in situ oil sands production, liquefied natural gas, and hydrogen.

Here are those videos in case you want to dive deeper into other energy topics:

Hydraulic Fracturing

Explains how “fracking” works.

In Situ Oil Sands Production

An alternative to mining in the oil sands, this video show how in situ production works.

Liquefied Natural Gas

This video shows how natural gas is liquefied, and transported to other markets.

Hydrogen

Examines the potential of hydrogen, along with the issues surrounding it. Also explains how fuel cells work.

The Highest Electric Vehicle Sales, by Model

Ranked: Electric Vehicle Sales by Model in 2023

Electric vehicle (EV) sales are gaining momentum, reaching 18% of global vehicle sales in 2023.

As new competitors bring more affordable options and new performance features, the market continues to mature as customers increasingly look to electric options.

This graphic ranks the top-selling EVs worldwide as of August 2023, based on data from CleanTechnica.

The Best Selling EVs in 2023 (Through August)

Below, we show the world’s best selling fully electric vehicles from January to August 2023:

ModelCountryVehicles Sold
(Jan-Aug 2023)
Tesla Model Y🇺🇸 U.S.772,364
Tesla Model 3🇺🇸 U.S.364,403
BYD Atto 3 / Yuan Plus🇨🇳 China265,688
BYD Dolphin🇨🇳 China222,825
GAC Aion S🇨🇳 China160,693
Wuling HongGuang Mini EV🇨🇳 China153,399
GAC Aion Y🇨🇳 China136,619
VW ID.4🇩🇪 Germany120,154
BYD Seagull🇨🇳 China95,202

As we can see, Tesla‘s Model Y still holds a comfortable lead over the competition with 772,364 units sold. That’s more than double the sales of the #2 top selling vehicle, Tesla’s Model 3 (364,403)

But it’s hard to ignore the rising prevalence of Chinese EVs. The next five best selling EV vehicles are Chinese, including three from BYD. The automaker’s Atto 3 (or Yuan Plus, depending on market), is being sold in various countries including Germany, the UK, Japan, and India.

Meanwhile, Chinese automaker GAC Group also had two models of its Aion EV brand make the rankings, with the Aion S selling 160,693 units so far.

Regional market strength is also clear. For Volkswagen’s ID.4 model (120,154 units sold), Europe and China account for the majority of sales.

Given growing cost efficiencies and changing consumer behavior, global EV sales are projected to make up half of new car sales globally by 2035, according to forecasts from Goldman Sachs.
