Thanks to the advent of alternative power, no longer must we rely on depleting the planet of its natural resources, burning fossil fuels that cause pollution of the atmosphere, depletion of the ozone layer, can potentially be unstable (as in nuclear energy), and continues to increase in cost year after year. The main sources of alternative power are the following:

? energy producing crops: synthetic biofuels and direct combustion;
? wind power and power from waves and tides;
? hydroelectric (water) power;
? solar power: heat and electricity;
? heat power: from man-made and natural waste products and from the making of synthetic bio-fuels;

By definition, an energy resource is renewable if it is replaced at a rate equal to or faster than the rate at which it is consumed. Renewable energy is therefore also considered sustainable energy, since it will continue to be available in unending supply even as it’s being utilized. Renewable energy has also been given the moniker alternative energy in reference to the alternative it offers to conventional, non-renewable sources.

Renewable energy can be utilized in one of two ways:

? directly: as in water mills, windmills, solar ovens, geothermal heating;
? indirectly: using the renewable resources to create other sources of power, either as fuels (biodiesel, bioethanol, biogas) or by generating electricity (wind turbines, solar panels).

Before renewable energy replaces the conventional sources of power that we’re used to (ie. public utility grid power), it will take years of research and development, continually studying, experimenting, improving, and innovating. The study of renewable energy, its applications and repercussions is concerned with environmental, economical, social, and political factors.

The reasons for switching from conventional, non-renewable energy to renewable energy are vast and varied, and the list grows larger every day. Among them are:

? it has a small to nil environmental impact with little to no harmful emissions, as a result supporting and protecting our natural ecosystem for future generations to enjoy;

? supplementing utility power with renewable power allows you a precious and invaluable backup system in the case of emergencies such as power outages and shortages;

? once a renewable energy system is installed, the energy costs a consistent amount to use year-round – as opposed to utilities that fluctuate in price throughout the year based on seasonal as well as socio-political factors;

? it is “distributed” energy, or energy that is used in the same location where it is produced – this cuts down considerably on transportation and distribution costs;

? many local and state governments as well as the federal government offer incentives in the form of tax breaks for the production and use of renewable energies;

? if you produce more power using renewable resources than you need for your own personal use, you can actually sell that power back to the utility companies in a program called “net metering”.

To complete a truly well-rounded discussion on renewable energy, there must be equal time given to its drawbacks as to its benefits. The most prevalent concerns about the long-term viability of renewable energies are that it is extremely dependent on numerous climactic factors and that it is considered “diluted” energy in that much more is needed to generate much less power. These so-called drawbacks, however, are no reason not to continue a fervent pursuit of incorporating renewable energy usage into more and more parts of our everyday lives. They are only to keep us present to the issues we must address in order to make a widespread switch to renewable energies a viable reality.

There is a lot to be said for the new crop of environmental-friendly, retiring Baby Boomers that are refusing the canned retirement solutions that are out there aplenty. Many have had to live in the cities that created their employment…complete with smog and crime. Years have gone by, the kids have been protected as much as possible in gated communities and the day has finally dawned when it’s time to take a look at “what’s next.”

The idea of travel that so held the attention of their elders has less appeal to our Baby Boomers. Cruise ship horror stories and the risks that have become part of RVing have taken the shine off of what their parents were satisfied with. Also, many have traveled extensively in their work and have added expensive vacations to far away places with strange sounding names to the mix.

Freedom doesn’t even have the draw that it had for earlier generations. Many Baby Boomers have been connected with web-oriented businesses and have been able to work at home some of the time, following their own pace. This usually meant longer hours for most of them, but more personal freedom was involved.

As a result this new breed wants to get the heck out of Dodge and do some kind of physical work. That’s right, they don’t want to be taken care of or sit around the campfire, they want to address the challenges that correspond with their ideals.

Peace and quiet rate high on many Baby Boomers’ lists of priorities. Living more simply calls to them. “Off the grid” was not a phrase most of us were familiar with even ten years ago. If we had heard it, it would have been with fear and loathing that we would have considered living without being connected to a reliable power source. However, these up and coming retirees are often extremely interested in solar panels and battery banks. Conservation and personal independence rank high.

In addition, unique designs for homes that circumvent the need for central heating and air conditioning are coming to the fore. The strawbale house is a wonder in temperature economy. Thick walls of dry bales of straw are covered with a “skin”. The one I recently viewed was plastered with a mixture of adobe mud and cement. Contractors and architects are getting on the bandwagon as this trend spreads. Books and seminars on strawbale building are under heavy demand.

And then there are the Earth Ships. These are energy-efficient homes dug into hillsides and constructed with great care to offer shelter without messing with the environment. The one I visited looked amazingly cozy.

Our Baby Boomers want a new kind of challenge and most of them are extending it into organic gardening, another science that offers them simplicity and increased wellness. They want to grow what they eat to a great extent. There’s usually plenty of room to do this because they buy acreage not a lot. This movement toward healthy living isn’t carefree but that’s not what most of them are about. They are willing to work long and hard.

You will find, in their strange residences, battery-run, lap top computers! After all, email, like life, must go on! Boomers are making sure that the things that matter to them are included. It’s never been about denial. For lack of a better description, I would call their evolving ethic “creating a challenging simplicity.”

If you get a chance to read up on this movement and/or have an opportunity to visit someone who is immersed in it, don’t pass it up. Rome is being rebuilt, yet again.
