Wind Power in Emerging Markets‏

Wind Power Power is the backbone of any economy in today’s world. But the high price of fossil fuel is forcing countries to focus on renewable energy sources. As a result, more technologically-developed countries have replaced a considerable portion of their fossil fuel power with renewable sources to sustain concrete growth. But, according to “Wind Power: Opportunities in Emerging Markets”, emerging countries, who have just started their journeys, also need to maintain a robust power supply for a number of reasons: most of the emerging economies are preferred destinations for industrial and manufacturing plants set up by developed countries, development of power grid connectivity has boosted up the power consumption, and increasing population has fueled the power requirement in developing economies. However, rising fossil fuel prices are challenging the growth potential of these countries. Therefore, like developed countries, these nations too are adding renewable sources in their power mix.

For many of these emerging countries, wind power seems to be the best choice as it is relatively low cost than other renewable sources and is a cleaner source of energy. With technological development, wind will become a highly competitive source for power generation, creating business opportunities for manufacturing and material innovations. This, in turn, will boost the manufacturing sector of the emerging countries.

Determining Electricity Consumption of Your Home Appliances

Improving energy efficiency and conservation around the house requires a certain attention to detail. There are a multitude of electronic appliances that populate the modern home. Knowing how many watts of electricity each appliances uses is a key step toward reducing your electricity consumption. You’ll know which ones to trade in for newer, more efficient models- creating a general awareness and knowledge that will aide in all of your energy conserving endeavors.

Figuring out how many watts of electricity an appliance uses is typically very easy. It is generally printed right on the device. It will either be stamped on it somewhere or printed on a nameplate that is usually affixed to the back.

If the number of watts is not printed on the device, then look for the current, in amperes (A), and voltage (V). Most appliances, from stereos to toaster ovens, use 120 volts (the maximum voltage for a standard outlet). Larger appliances, such as clothes dryers, may use 240-volt outlets. To find a unit’s wattage, simply multiply the amps and the volts. For example, a device drawing 5.0 A at 120 volts is using 600 Watts of electricity.

In the typical home, water heaters use by far the most amount of electricity, drawing 4500-5500 watts when running. The clothes dryer, dishwasher, and vacuum cleaner are also big electricity users. Just remember that an individual appliance’s cost to each household is different based on how much the appliance is used. For example, a laptop computer typically uses only 50 W of electricity (somewhat less in sleep mode) and a dryer may use 5000. But if the computer is left on 24 hours a day, and the dryer is rarely used because you dry your clothes outside on a line, then suddenly the smaller, more efficient computer has the higher cost in electricity. Being energy efficient is as much about lifestyle and the way we use the products we purchase as it is about the products themselves.

Bear in mind that the wattage listed on an electronic device is its peak level of consumption. That is to say that electronics such as stereos, with volume controls, may not be drawing the maximum number of watts at all times. It all depends on the setting.

When evaluating the energy efficiency of any device, it is also important to factor in “phantom” loads, or the small amount of electricity that a device draws, even when it is switched off. Televisions, stereos, computers, all such devices carry phantom loads. These are small amounts but can really add up, especially considering the number of appliances in the average home. To avoid this issue, either unplug appliances when unused, or plug several into a power strip and then switch the strip off when the group is not in commission. The power strip method is an excellent choice for computer desks and home entertainment centers, where all components are typically used or shut off at the same time.

For more information on calculating electricity consumption and cost, including a list of common wattages for household appliances, see the U.S. Department of Energy’s Office for Energy Efficiency and Renewable Energy (EERE) website.

LA Biodiesel Station Saved by E-Mail Campaign

Happy Solstice from Holy Solar! This year has seen an amazing growth of alternative energy, real action from Washington and credible promises of much more to come from what may prove to be the administration which solves the energy crisis.

We’ve been away for a couple of months performing seasonal agricultural work on the Coast, and just now completed our regular migration to the Southwest. The price of biodiesel has not been as fast to fall as it was to rise, and remains up to twice the retail of petro-diesel.

Fortunately, we were able to navigate the 1000 miles of highway without resorting to dinosaur diesel, thanks largely to the four fueling stations we depended on, and several contributing riders. By pooling fuel costs, were able to complete the trip at a personal cost of $.15.mile.

We made our usual stops at the Biofuel Station in Laytonville and the Real Goods pump at the Solar Living Institute in Hopland (map). The BioFuel Oasis in Berkeley (map) saved our schedule by staying open late (8pm) and by selling easy-to-use 5-gallon jugs. This extended our range to cover the distance to Los Angeles non-stop, where ConservFuel provided the best price and hours of the entire journey.

The bad news came a few days later-ConservFuel in West LA, where we had just purchased 47 gallons, was discontinuing biodiesel. For those who travel long distances on biodiesel as well as local consumers, this essential oasis has been the only 24-hour provider of B99 in Southern California.

This was the e-mail we received from Kent at Socalbug.com:

The owner of the ConservFuel Station in West LA/Brentwood has decided to stop selling biodiesel !!!
See the explanation on the http://www.conservfuel.com/
website.

Write Dansk a letter and or email them @ biodiesel@danskinvestments.com include info@conservfuel.com ( Kris Moller ) as a cc: in your email.

However don’t be too harsh, we do not want them to get sour on biodiesel as Dansk also owns the Palisades Gas-N-Wash which is still selling biodiesel.

Do your part to keep biodiesel for sale at ConservFuel.
Write your letter, spread the word and take action.

Kent

Here is what we had to say about it:

Dear Biodiesel Providers:

We were most saddened to hear of the closure of the biodiesel pump at Conserv fuel, especially after our recent fill-up just last week, when we purchased what will apparently be our final tank of hard-to-find biodiesel there.

On our seasonal trips from Arizona to Oregon, Conserv is a critical stop. We usually arrive at odd hours and the end of our tank. I honestly do not know how we will manage our next trip, as there is a huge void of biodiesel throughout that stretch of 1-10.

Many people do not understand why we use biodiesel, even when petro-diesel is cheaper. There are many reasons, from socio-political, to environmental, but the at the bottom of it all is a belief that biodiesel is a superior alternative which must be supported even at a higher cost. We are not wealthy people, but there is no compromising on this for us. We resort to petro-diesel only in the gravest emergencies, when there is literally no possibility of obtaining biodiesel.

We are cognizant of the difficulty of maintaining an unprofitable product, but urge your reconsideration of this move. The year has been a turbulant one for fuel prices, and next year may become more so. Biodiesel may again become a strong and profitable product as breakthroughs in algae and jatropha feedstocks swell supplies.

Please be aware that this closure is a major inconvenience, not merely to the local population of committed biodiesel users, but to travelers on the nation’s highways who lack other oases of supply. This issue is quite serious; we are quite literally stranded without a 24-hour station.

We may not have been contributing to your company’s coffers as well as consumers of cheaper fuels, but biodiesel users are dependant on the West Hollywood B100 pumps, and without them, the journey toward a greener future is  detoured.

We urge your reconsideration.

Holy Solar Alternative Energy Bus

And we were pleasantly surprised to see this response:

After careful reconsideration and deliberation, Dansk Investment Group has decided that the loss our valuable biodiesel customers is not worth the potential increase in profits that would be gained by  switching to the lower cost diesel #2.  In large part, due to the numerous, well articulated emails we have received regarding our customers reaction to our removal of biodiesel, Dansk has decided to bring back biodiesel (B99) to Conserv Fuel in West Los Angeles!

Your emails are testament to the exceptional loyalty that Conserv Fuel biodiesel patrons have demonstrated regarding your commitment to purchase biodiesel.  Conserv Fuel will once again continue to be the sole retail supplier of biodiesel (B99) in the greater Los Angeles area.   Please note that our higher biodiesel sales price relative to diesel #2 is due to our higher wholesale supply costs.  There is currently a lack of biodiesel supply in California which has resulted in biodiesel selling at a premium price to diesel #2.

We appreciate you taking the time to express your sentiments and would like to inform you that your voices have been heard.  We understand that your loyalty to Conserv Fuel is linked to our supply of biodiesel, so we will be switching back to selling biodiesel (B99) hopefully by December 20th, 2008.  We will keep you updated on our return to biodiesel at www.conservfuel.com

We appreciate you for your continued support

Dansk Investment Group, Inc.

Ours was merely one of many letters that surely led to this reversal, and this demonstrates the importance of expressing the importance that alternative energy makes in our lives to those deciding whether to provide it.

If you use biodiesel in LA, or expect to ever need to, please send a brief letter of thanks to the folks at Dansk Investments…and stop by the ConservFuel station to fill up often once biodiesel is restored there on December 20.

Dansk Investments & SoCal Bug jointly share this weeks “Green Leap of Faith Award” for believing in biodiesel through these rocky times.

ConservFuel can be contacted through email at biodiesel@danskinvestments.com
They are open 24 hours a day, located at
11699 San Vicente Blvd

Federal Tax Credit Increase Brings Solar Within Reach

The recent stock market collapse and subsequent Congressional bailout have brought a collective groan to pocketbooks across America and financial markets around the world. Afraid for their savings and jobs, and worried for the future of their homes and college funds, this may not seem like the time for homeowners to invest in expensive improvements.

The $700B corporate welfare package was passed through Congress, much as previous legislation overreached the bounds of government on the pretext of crisis. Stuffed with pork and served with theater, this move will haunt the world economy for years to come.

There is a silver lining to the dark storm cloud rising, however: the alternative energy tax credit cap has been quadrupled to $8000, bringing the effective cost of PV installations down by 1/3-1/2. The credit applies to 30% of the total installed cost of new residential systems.

Solar InstallationFor California residents, this can be added to the $2.50 credit to make solar a truly affordable alternative to the grid. Other states have different rebate programs. Depending on where you live and how much tax you typically pay, the cost of a grid-tie solar system might be offset up to 50%.

Contact a representative at Real Goods Solar for more information on solar installation and tax rebate credit incentives available where you live.

Google Grabs Green Leap Award for Alternative Energy Plan

Search Engine Giant Google Wins Green Leap Award

Google Goes GeenThis is a new feature we’ve added in order to highlight organizations and companies who have made noteworthy contributions to developing a clean energy policy based on renewable power. We recently profiled Cal Green Lending, Real Goods, and Nanosolar, and these companies are retroactively awarded this distinction as well.

Today we’d like to salute…well…a giant media corporation. Not just any multibillion-dollar press magnet, either; Google is the most active web entity on Earth, attracting over 80 million visitors daily to its search result pages and other web services.

“To Google” has become an infinitive transitive verb meaning, “to instantly research any topic.” According to our site statistics, there is a 75% chance you arrived here via Google referral.

Google exercises god-like power over the Internet, defining the user experience and revolutionizing the core concept of advertising with the Google Adsense program, which enables millions of independent content creators to easily place ads on their site.

The start-up in San Jose has gone on to become one of the wealthiest corporations on Earth, and many online talking heads (and the courts) regularly debate the dangers of concentrating so much power in a single company. What is not debatable is that Google is one of the most active corporate voices on behalf of alternative energy.

Google has been putting these considerable funds where its press releases are, adding the world’s largest solar array to the Mountain View facility, and we’ve reported previous;y on the investment founders Sergey Brin and Larry Page have made in the ultra-thin printed solar modules from Nanosolar.

The latest news is the best yet: the “.org” side of the loudest voice in technological development has issued a bold plan to “Green the Grid” and shift the majority of energy production away from fossil fuels by 2030. Drafted by Jeffrey Greenblatt, who is the Climate and Energy Technology Manager for Google, the analysis recommends an investment of $4.4 trillion in a combination of solar, wind, and geothermal power. The program calls for 88% of grid electrcity to be produced from earth-friendlier technology by the target date.

We’d like to quibble a bit with the low goals for the vehicle fuel aspect of this plan…a piddling 38% percent reduction of petroleum in 20 years. The plan focuses on using electricity for transportation , which is nice, but will require a completely new infrastructure of charging stations and new vehicle factories,

Greenblatt also oddly presumes that electrical power will be cheap and abundant, which seems unrealistic, considering the effort which will be needed to accommodate existing and inflating demand for household and commercial electricity. We’d be robbing the lights to pay the tank.

At Holy Solar, we’d like to see 80% or more of a reduction in petroleum fuel by 2030, which can not be accomplished with electric cars alone. We were not able to find a single reference to the role of biofuels. Also, the notion of offering rebates to “retire older cars early,” is wasteful of the existing vehicles and the energy that went into building them.

It also ignores the millions of poor who have never owned a new car and probably never will. This was clearly a plan drawn up by someone with a well-paying career, but the fact is that this comes at a time when auto manufacturers are struggling to sell new vehicles at all.

So, as you stride up to the podium to collect your award, Dear Google, please do take a moment to think bigger about the potential of biofuels to achieve for vehicles what solar, wind and geothermal power do for electricity…allow a gradual shift while salvaging the existing infrastructure. Let’s not throw millions of vehicles to the scrap heap when a simple modification can make them burn more cleanly.

Nevertheless, this plan is admittedly a first draft; what we’d like to salute is the way this media giant is pioneering the dialogue about going beyond the inconvenient truth to investing in the technology to make this the time for a Green Revolution. Therefore, Google is hereby named winner of this week’s “Green Leap Award.”

Sustainable Aviation: Bio-Fuels Reach the Stratosphere

Flying the Earth-Friendly Skies

Biofuel enthusiasts have been saying for a long time that the sky is the limit for organically-based, sustainable transportation solutions. Now, that barrier, too, seems to have been rapidly passed. With the announcement of the world’s very first organically produced aviation fuel from micro-algae, San Francisco biofuel pioneer Solazyme may have helped solve the missing link in the alternative energy puzzle.

The new jet fuel, which is made from algal culture grown in vats from a sugar medium, addresses the enormous global issues tied up with petrochemicals as fuel for flight, just in time for the sixth anniversary of the Word Trade Center destruction. This development comes on the heels of tests earlier this year by Virgin Airlines, which has since moved its program to Europe.

There is tremendous philosophical significance in this announcement, as it heralds a time in the near future when air travel which does not have the political or environmental implications of fossil fuels so candidly illustrated by that devastating event. Jet fuel is an energy cost hidden to the average consumer, who generally only feels the impact indirectly as part of airline fares.

With this innovation, it has now become technically feasible to power every sector of industrial, transportation, and residential electrical needs, all by means of a renewable energy source. This is a milestone to give a little cheer about, and that it has been accomplished in so little time should serve as encouragement to those of us concerned with a sustainable energy policy.

The process will still need some perfecting, and the political will to wrest lucrative jet fuel contracts from the oil companies may be in shorter supply than oil itself. Nevertheless, we are seeing again and again that Nature offers an answer for a post-petroleum revolution.

Alternative Energy Financing :
Making Solar Make Sense

Fed up with paying in to a private monopoly which is still holding us hostage with pollution-generating power plants? Tired of talking about the energy crisis and ready to invest in a future off the grid? Good for you.

Now that you’ve decided to go solar, you face some tough choices about finances. The power generated by the Sun is 100% free, but the photovoltaic collectors which convert this energy still represent a substantial investment. A little sticker shock is common among homeowners who have estimated the household electricity use, and found that their planned solar array will cost as much as a new vehicle.

The average home practicing energy-conscious conservation is using 5-7 Kwh/ day. In order to depend entirely on solar power, this home might need about 2 or 3 KW of PV module, at a jaw-dropping cost of at least $5,000 per kilowatt. Grid-tie installation can often cost up to one-third of the total, and a state-of the-art inverter, backup generator, and storage battery cells can bring the total into the stratosphere.

The math may be daunting, but through a little creative conservation, applicable tax credits, and financing from lenders friendly to environmental projects, most residential solar installations become a practical reality. Some homeowners are pleased to discover that their home can be solarized for even less than their current electricity bill.

Most homeowners are aware of Federal alternative energy tax incentives of $2,000 and 0% interest bonds which may offset part of the cost, as well as various state programs. These can bring down the total cost of the project, but most middle-class homeowners will still be tempted to balk at committing a year’s salary to a single purchase.

The answer is the same mechanism which made it possible for you to own your home in the first place: a loan. While the notion of going even further in debt may not appeal at first, it bears pointing out that a solar or wind system begins paying for itself from the moment of installation, by reducing or eliminating the monthly energy bill.

By distributing the cost of PV modules, invetrters, and grid-tie installation across 15-30 years, the monthly cost of home electricity is locked in near the current rates, until the loan is paid and the energy becomes entirely free. Another key consideration is that the investment in a solar or wind electrical syatem adds value to your property-an added 20/watt, according to current assessment guidelines.

In addition to hedging against likely hikes in local energy prices, adding solar power is a wise investment in home improvement. Since solar homes are still reasonably rare on the market, and increasingly in demand, alternative energy amentities may also help a home sell more quickly…an important consideration in a sluggish real estate market.

Of course, your bank may not be cutting-edge enough to recognize this. The lending market is quickly growing conservative in the wake of recent foreclosure fiascoes, and some agents may fear risking the primary mortgage by adding a second one.

Fortunately, the green movement is spreading into all corners of the economy, and by choosing a lender such as Cal Green Lending who specializes in financing environmental projects, you can be sure that your application will be reviewed by lenders who comprehend the viability of alternative energy.

Cal Green Lending arranges loans to qualified alternative energy installation projects for both residential and commercial properties nationwide. Visit them to see if they can help make your solar dream a reality.

Cal Green Lending has been awarded the “Green Leap Award” from Holy Solar for making an innovative leap in the approach to alternative energy.

Nanosolar: Thin is In for Renewable Energy

Enough sunlight falls on the Earth in two hours to support all of civilization’s power needs for an entire year. This compelling statistic ought to have mobs unplugging from the grid and off to the solar store for some PV modules and wires. When we see how energy is free, that it literally falls from the sky and all we have to do is collect it, why should we live under the whim of a heartless energy monopoly, in dread of their threatening pink notices?

At some level, however, we all know that unless the grid itself is powered by renewable energy, the economic, social, and environmental plague of fossil fuels and nuclear power will go on to pollute the world regardless of how tiny our individual footprints may be.

So the best news, lately, has been about the solar we can’t have: industrial-strength adaptations for large-scale solar power that are beginning to answer some of the shortcomings of our favorite energy source. Traditional mono-and-polycrystalline panels are a technological wonder, but mass-producing them presents some economic and environmental problems of their own. Many people worry about the long “energy debt” these panels have, often three to five years before the energy to manufacture such panels is recovered.

The focus in solar equipment manufacture has shifted from the watt to the megawatt, and the entire premise of solar collection is rapidly evolving. Since solar panels obviously need to cover the maximum surface area, engineers have been hard at work on that third dimension, reducing the thickness of each module.

They haven’t stopped there. A company called Nanosolar is now producing solar cells so thin that they are literally painted on, collecting charge by means of a special ink. Want some? You can’t have any; despite enormous investments from giants like IBM and Google founders Larry Page and Sergey Brin, as well as reports that the company’s new plants have the ability to produce 1 billion watts to wholesale at about $1 a piece, Nanosolar says it is sold out for at least a year in advance. Try again in 2009.

Boasting an impressive 14.5% efficiency and the lowest cost yet for photovoltaic cells, we can’t wait until this technology makes it to the consumer level. Unfortunately, since the technology is patented and proprietary, and Nanosolar shows no interest in the residential sector, it will be some time before microsolar makes its way to the open market.

Nanosolar has been awarded the Green Leap Award from Holy Solar for innovative advancement in the approach to alternative energy.

Until then, we’ll have to get by with the next-best thing, solar cells which are merely thin, available from Global Solar and UniSolar. See these thin-film solar cells available from Real Goods.

Drilling & Mounting-RV Solar Panel Installation

Part Two

In the previous post, we covered some of the main reasons why we chose the Unisolar 64 Watt solar panel for supplemental power in our alternative energy bus. We made the purchase at the Real Goods store in Hopland, California, but because our roof had no metal to fix the mounting brackets to, installation was pretty much up to us.

Erik at Real Goods helped us develop a plan, drew a diagram showing the proper way to hook up the wiring between the junction box of the solar panel, the regulator, and batteries, and wished us well. We had his card in the event of emergency; fortunately, we never needed it.

The first issue we confronted was the fiberglass roof. Since Mahayana was not new when we met her, we lacked electrical diagrams of the wiring scheme, although we could make some educated guesses. We decided that the region on either side of the visible wire bundle ought to be safe for drilling, and this turned out to be correct.

Along with the Unisolar Thin Film Panel, we chose the Uni-Rac RV mounting bracket seticon, which brought the total bill to just under $500. The bracket set is simple enough, but to avoid undue stress to the fiberglass, we mounted a T-plate to the roof beneath each bracket and attached the mounts to those.

This works well, but at high speeds there is some vibration noise, which makes us wish that we had insulated the T-plate with felt “washers,” such as battery terminal pads. Live and learn!

Each T-plate was mounted with a pair of fittings to the roof. The holes were drilled with a 5/8″ bit and secured with 1/2″ X 2 1/2″ mechanical bolts.

Since our solar panel is bus-mounted, we didn’t need to worry about connecting the panel to a ground, but those working on residential installations will need to ground the frame of the panel.

We drilled an additional hole through the roof in order to accommodate the positive and negative wires which passthe charge from the panel to the batteries, making a total of nine breaches in our ceiling. Preserving the integrity of the roof being a priority, we were glad to see that we made only as many as were needed. We were quite happy as well to see that the holes were confined to a relatively small area, approximately two feet across and three back. This means that there is room for at least one more panel like this if- and when- we expand our solar collection potential.

After making sure we had all of the wire, connections, splices and fuses we needed- all of which are included in the Global Solar Energy Extra Connectivity Kiticon– we proceeded to connect the SunSaver controller first to the deep-cycle marine batteries, and then to the panel. We made sure to splice the included fuse module to the positive wires on either side of the controller for overload protection.

It’s been a little more than two weeks since we added the Unisolar Thinfilm Panel to our alternative energy houseboat, and the results have exceeded expectations. The little green light, signifying charge, goes on with the first glint of dawn and stays fiercely bright, in shade and beneath cloudy skies, until the last flash of sunset disappears from the horizon.

RV Solar Installation- Unisolar 64 Watt Thin Film Panel

Part One

UniSolar Thin Film Panel From Real Goodsicon
We are proud to announce that the production of this site is now completely solar powered, as our two computers currently run off of our recently installed Unisolar Thin Film solar panelicon, which soaks up light like a sponge and allows the two of us to write and design to our hearts content, without using fossil fuels or depending on grid power.

Frankly, we’re pretty excited about it. Our hardy road-boat, Mahayana (which means “The Big Vehicle,” a type of Buddhism), has sailed the highways for over two years under the faint scent of French fries from the biodiesel she drinks with glee. Adding a solar panel to our array of alternative energy was a logical next step, but we found suppliers and information to be shockingly scarce…which is part of what motivated the construction of this site.

As the great Bobby Weir still sometimes sings, “it’s all too clear we’re on our own.” Switching to alternative energy made us amateur electricians for a few days, with an emphasis on amateur. Neither of us had a lot of experience in drilling and wiring, but there was no choice but to learn the basics. Installing a solar panel on the bus brought this home, and fortunately we had the time and patience to carry it off without mishap.

The first task, of course, was choosing the right panel. We went with the Unisolar model for several reasons. First, unlike its vulnerable mono-and-polycrystalline counterparts, the ThinFilm technology is considered “unbreakable.” Of course, you shouldn’t take a sledgehammer to any solar panel, but the manufacturer asserts that it can sustain normal impact without damage.

There will surely be many unplanned tests of this claim as we travel, so we’ll let you know what parking stupidities the Unisolar has survived, or-perish the thought-failed to. Physical damage to the panel is definitely a risk in the wooded regions we travel, so we wanted the most durable design available.

The second reason we chose the Unisolar 64 has to do with how it collects light. The amorphous solar panel design is much more efficient in partial shading than panels composed of serial cells, which can fail to perform if even a portion of the panel is in shadow. In fact, the charge indicator light shows that the Unisolar is passing current to the regulator, even in complete shading on an overcast day.

The downside to the Thin Film style of collector is that the surface is not as efficient as other types of panels per square inch, which means that our 64 watt panel has the physical dimensions (about 54″ X 30″) one normally associates with grid-tie panels of 100 watts or more. The ES series is versatile and is perfect for auxiliary power on boats, RVs, and remote work trucks as well as residential grid-tie and even massive megawatt arrays.

For us, the slightly larger surface is no disadvantage at all, as Mahayana has ample roof space and room for two more such panels should we ever need them.

In the next post, we’ll describe the DIY installation process, what we learned, a few helpful tips for those of you considering going solar, and links to all the equipment you’ll need for personal energy independence, with a little help from nature.

It feels wonderful. Thank you, old Sol!

Solar Powered Portable Reading Devices

Solar-Powered Digital ReaderWhen Gutenberg first built his printing press, he probably wasn’t the least bit concerned with the environmental impact.

And for the first 500 years or so that his seminal invention helped reproduce the philosophies, theories, and conclusions of the finest minds in Western and Eastern cultures, it wasn’t much of an issue. Woodlands were abundant, print runs relatively short, and storing the sum of human knowledge certainly ranked in importance above a few trees.

Wholly Solar

The purpose of this site, as we’ll keep mentioning until we’re sure it has been made quite clear, is to advocate for and provide information on renewable, nonpolluting energy sources. There are quite a few reasons why we feel this is important, but all of them boil down to a concern over the toxic social, economic, and environmental impact of petrochemical dependence.

The solution, we believe, is to turn to nature. When we talk about solar power, we don’t just mean photovoltaic modules, although that is certainly one of our favorite forms of electricity generation. Solar power includes windmills, biofuel, and non-PV applications such as solar heaters and ovens.

In fact, in a sense all of the power on the planet derives ultimately from the Sun, even those nasty petrochemicals we so avidly avoid. Yet there is a conceptual distinction between using dead, stored energy from a limited and ecologically problematical cache, and choosing from a panacea of naturally clean power which replaces itself with each new day.

Slapping solar panels on every rooftop in the world might go a long way toward addressing the petro-mess, but that isn’t going to happen overnight, and it will never happen unless the people collectively demand it.

Some individuals may feel that the threat of climate change is exaggerated, or that oil is more abundant than current projections indicate. Others are inclined to believe that the green movement is a liberal conspiracy to attack businesses with taxes and regulations.

We may not be able to convince these folks. That’s not our job. We are here to evangelize to the choir, to provide a perspective and strategies as much as tools and applications for green living. Converting the critics is a job we leave to those of you able to combine honesty with diplomacy. They’ll come around, once they realize their tree-hugging neighbors don’t pay an electric bill.

Can the energy needs of the entire species be accommodated by green power? We believe the answer is: absolutely. Within the decade, if a planet-wide initiative takes hold as we dream. The technology exists and improves daily. No system is without disadvantages, and underestimating the challenge would be a mistake.

Nevertheless, the time is ripe for a transition that could sweep the globe with positive effects, not only in the ways we gather energy, but the way we approach nature and economics as well. We are at a crossroads, and the type of technology choices we make today will have an impact on how tomorrow’s civilization collects and uses the power to live in harmony with the Earth…or render it forever uninhabitable.
