Wake Up to the Abundance of Energy

Energy finally seems to be getting the attention it deserves. People are recognizing the rising demand around our planet, and many are talking about energy shortages as developing nations start utilizing more energy themselves. But the reality is that we are surrounded by an abundance of energy. The earth is truly blessed.

The mindset of energy shortage comes from a tunnel vision focus on fossil fuels. That limited focus is drying up supplies and poisoning our planet. What is needed instead is for developers to take off their blinders and wake up to the enormous supply of untapped energy that surrounds us. I am not talking metaphysics here. I am talking about natural energy.

Here's one example. Long range forecasters are predicting some critical fresh water needs in the future that current delivery systems cannot accommodate. Many areas are already feeling the strain. Obviously, more needs to be done with water reclamation. But additionally, many are calling for much more to be done with the desalination of seawater. A major obstacle to that has been the high energy demand of such operations. Imagine, though, a desalination plant that harnesses the local power of the tides, the wind, and the waves to generate the electricity required to operate and pump the water. The output of the plant might be somewhat variable, but it would take no energy from the grid. Instead, the facility takes the energy from its environment.

We need to get away from the all or nothing approach to supplying our electrical energy needs. There is an enormous amount of energy lost in transmission from a central location. Envision, instead, a community in which every building has roof shingles that not only perform the usual protective functions but also convert sunlight into electricity for use in that building. In most locations, this would not be enough to substitute for the electrical grid, but it could certainly supplement. If the building is making use of a subterranean heating and cooling system, the power to provide the air circulation could all be generated on site. (Google "subterranean heating and cooling" for more information.)

This sort of decentralization of power supply can make an enormous difference in parts of the developing world where the infrastructure for power delivery has not been put into place. In many respects, it is similar to the way in which cell phone service has reached many areas were there are still no telephone land lines. These countries will be able to modernize more quickly and with less investment in infrastructure with this type of technology. As a bonus, it will have less negative impact on the environment.

What we need now and in the future is more creative energy. Sometimes, we need new technologies. Sometimes we just need new applications of very old technologies. Either way, we'll be drawing upon the abundance of energy that already surrounds us.

That's Wade's two cents.
