Iceland: Geothermal Energy

Renewable Energy No Comments »

In Iceland, geothermal power is being used for almost everything — from heating homes to supplying therapeutic spas year round. Scientists and engineers from around the world are participating in a course at the United Nations University (UNU) to learn how to use geothermal energy in their own countries from leading experts in Iceland.

Off-Grid Hydro Power: Too Much Power!

Alternative Energy No Comments »

This off-grid hydro power system has a major problem; too much power. Jeff has stumbled upon a small clan of off-grid homeschoolers and discovers that their power system is a major source of angst.

Their stream engine produces around 1200-1300 Watts continuously and their load controller must get rid of any excess power by dumping the power into a hot water tank. Image the struggle to use copious amounts of hot water!

Nuclear Energy Explained: Risk or Opportunity

Alternative Energy No Comments »

Please Read Below For More Information

Anything with the word nuclear next to it usually comes with a fair bit of misunderstanding. Hopefully this video demystifies the process of how nuclear fuels are turned into electricity and how we can use them in combination with renewables in order to reduce greenhouse gas emissions and the effects on the climate that come with high levels of them.

Of course, there are many things that have been left out this video as nuclear energy, just as with any other source, has many different factors that need to be taken into account when making decisions. In order to fully understand the situation and make decisions, I highly recommend that you do some research of your own on the topic, rather than simply base your opinion on a four-minute YouTube video.

It should also be noted that this video has been made from the perspective of the United States in general. Every area on Earth has different natural resources and environments that determine what works best there.

On a lighter note, feel free to keep up with WhatTheWhy on Twitter at . Thanks for watching!

Hydropower – Power of the future or relic of the past?

Alternative Energy No Comments »

Hydropower has been the largest global provider of renewable electricity for over 100 years and represents the first mainstream source of renewable energy. However, many environmental groups don’t view large-scale hydro as truly renewable. So what is it? Is hydroelectricity a foundation of our energy future or something better left in our past?
