Compare Energy Prices in Ontario for Proof of Concept

When I attended the Solar World Congress in Orlando’s tourism district 2 years ago, I learned a great deal about the technology of renewable energy, especially solar, as the event’s name suggests. One of the most intriguing solutions I saw there, applied in a few different ways, was the solar air conditioner. In fact, one of the presentations on the subject was by NASA, explaining how lunar missions in coming decades will use it.

Sadly, while the most intriguing exhibits and speeches I saw at the Solar World Congress focused on the future, the technologies we use today for generating electricity and then cooling and heating our homes is firmly rooted in the last century. I am very bullish about the promise of geothermal energy and believe that I can convince you to feel the same way.

So, how helpful could it be?

Rising U.S. Energy Prices Have Solution To The North

In my previous post, I explained that I am enthusiastic about geothermal energy. The good news does not end with the fact that this abundant resource is clean and renewable. No, it also can lead to stability in energy prices.

Because the fuel is expensive and must be extracted from the earth, the price we pay for conventional energy is volatile, subject to multiple market forces. When we add economic expansion and shifts between population centers, the result is inevitable, rising U.S. energy prices.

Nature has given us a clean solution which also can be quite inexpensive over the long term, geothermal energy.

Soil temperatures beneath the surface of the Earth are constant so we can use the unchanging conditions there to control the temperature of our own surroundings by routing our ventilation system through underground chambers. Applied cleverly, we also can generate electricity cleanly by exploiting the difference in temperature at the surface and deep below.

Should We Focus On Solar Energy Or Geothermal?

I love renewable energy. It is clean and, in some cases, free to harness. Which is the right answer for your situation, however? Without visiting your home, I cannot state for certain but what I can do is offer my perspective, which cares equally for keeping the earth green and providing you with the energy you need.

Every form of renewable energy has its advantages. I tend to prefer solar because of the relative ease of installation of the equipment to harness it and the vast untapped potential. As you may know, the world uses a mere fraction of 1% of the solar energy which strikes the surface of the Earth every day.

Solar doesn’t work everywhere, however. Likewise, geothermal has the ability to generate most of the electricity we need and keep our homes comfortable year round but it does not work in every situation. So, should we focus on solar energy or geothermal?

Masdar City Will Feature Green Sustainable Modular Buildings and Mutualism in the Desert

In recent posts, I have tiptoed around politically sensitive topics. Today’s thread will be no different. However, I ask that you strive to remain focused on the environmental theme at the core of the story. Folks in the United Arab Emirates are building a new metropolis, called Masdar City. Green sustainable modular buildings are a central theme and many topographic design principles borrow from mutualism in the desert.

At the following URL, you will find some interesting coverage of Masdar City. I ask that you pay particular attention to the 5½-minute video. It contains some exaggerations about carbon neutrality and the achievement of a zero waste stream. Nevertheless, Masdar City will be an impressive metropolis when complete (assuming that it lives up to its own hype).

Importance of Hurricanes Demonstrated on Exterior of Commercial Airline Flight

The intensity differential of sunlight striking the dark side of the world and the light side at any given moment is tremendous. It is the difference between night and day, no pun intended.

This is why the spacesuit visor for astronauts is so highly reflective. Conditions in space are such that without a proper suit, an astronaut literally could fry on one side of his/her body and freeze on the other because of the importance of solar radiation. Here on earth, those conditions also point to the importance of hurricanes.

Simply put, sunlight is very harsh. We need our atmosphere to regulate that harshness. During my second commercial airline flight Down Under, I flew between Los Angeles and Honolulu. It was a morning flight so the position of the sun was nearly constant along the port side of the aircraft. Indeed, the sunlight was so intense that my wife Catrin had to close the window shade for our row of seats.

Drake Landing Solar Community Proves Viability of Passive Solar House Design Even in Cold Climates, Blending Geothermal Heating with Solar Water Heating

"Okotoks can fairly call itself the greenest community in Canada, maybe the world."

– Stephen Harper

Prime Minister of Canada

The Drake Landing Solar Community, in Okotoks, Alberta has reached a highly commendable and very remarkable milestone in passive solar house design, blending geothermal heating in the summertime with year-round solar water heating. That may read like a mouthful but, in short, this 52-home solar community in Central Canada soaks up heat in the summer and uses it to keep families warm in the winter while using just the tiniest fraction of grid power and natural gas versus what it would through conventional design.

Now, we’re talking!
