A Sustainable Energy Future - dream or reality

Imagine this. The year is 2030 A.D. Renewable energy sources are supplying over 50% of the United States' energy needs. Total energy use has decreased dramatically from its exorbitant 1990's level. Multi-megawatt windfarms, solar thermal farms and biomass plants dot the landscape. Biofuels and solar-derived hydrogen make many of our cars, trains and buses go. Photovoltaic energy technology is converting sunlight directly into electricity in remote locations. Hydropower continues to provide electricity using such technology as run-of-the-river facilities which don't need huge dams. High-temperature and direct-use geothermal energy are household words; and geothermal heat pumps warm homes everywhere.

Is this a futuristic dreamscape? No, it is part of the sustainable energy forecast of many energy experts who are encouraging major state and federal policy shifts in order to make the above scenario a reality. The concepts of the sustainable energy strategy-combining energy conservation, environmental protection, and the use of "renewable" resources-are becoming integral to plans for wise energy use. In fact, many of these ideas are no longer dreams for the future. They are being put into motion today by leaders who want to see a cleaner, brighter tomorrow.

Every Breath You Take

The benefits of industrialization are many, but one of the dark sides of the era in which we live is air pollution. Some of the main ingredients of this nasty problem are nitrogen oxides (NOx), carbon monoxide (CO), sulfur oxides (SOx), particulate matter, things called "volatile organic compounds" (VOCs), and ozone (the ground level kind, not the beneficial type which occurs naturally as a protective layer in the upper atmosphere).

These are six of seven government-regulated emissions which are proven health hazards, and some 300 other non-regulated emissions are also known to contribute to health damage.

Where are all the toxics coming from? Power plants, factories, and transportation vehicles are the obvious big culprits. But there are other contributors too: wood stoves, fossil fuel-burning furnaces, paints, dry cleaners, and (surprise!) bakeries (due to the fermentation process). It's time we get to work ridding ourselves of these hazardous emissions. A good place to start is by using (whenever we can) energy sources which don't pollute, including geothermal energy.

How did we get into this mess?
a brief (not definitive) history of power

(by Deborah S. Page, for the Geothermal Education Office, c. GEO1999)

When prehistoric man began to make and use fire, we began the long road to harnessing the powers of nature. This need to command the use of power eventually accelerated us into the Industrial Revolution, on into the Modern Age and, with a final thrust, into the Technological Revolution. We are now at the point where our use of power has begun to harness us, often resulting in a not-so-healthy way of life - for people and for the planet. How did we ever get into this mess?

For early man, wood was the mainstay of life, providing fuel, shelter and transportation. Wind, water, the sun and animals were also significant power sources for centuries. As early as the 5th century B.C., Socrates was recommending passive solar homes. Records of water-mill use by both the Greeks and Romans date back to the 1st century B.C., while at the same time the Romans were luxuriating in geothermally-heated and wood-heated baths. Efficient windmills with horizontal sails came into use around 1180 A.D., and blast furnaces, introduced in Holland around 1400 A.D., used wood to generate very hot temperatures for the melting of cast iron. Though the use of coal had been recorded as early as the 1st century A.D., wood, wind, and water dominated the "power market" of Western civilization until the 16th century A.D.

The Industrial Revolution

By the late 1600's, coal had become the preferred fuel choice for heating in Britain. Then English coal mines flooded and prompted the need for a machine which could pump water out of the way of the miners. In 1698, the first patented steam engine was developed to do just this, paving the way for the development of steam power and ushering in the beginning of the Industrial Revolution.

At the same time, textile production was big business in Britain. Machines were soon invented to spin and weave faster and more economically. First driven by water power, they were soon run by steam engines which gobbled ever larger quantities of coal. The miners worked even faster, and many people began to move from the country to live near the factories and the mines. Thus, the first industrial cities were born.

A coal derivative, coke, which burned very hot, was developed, allowing an increase in the production of iron. This meant an increase in the number of machines. In 1712, pistons were added to these steam engines, enabling the engines to work even faster. While Ben Franklin flew his famous kite in 1752 (proving the existence of static electricity), James Watt developed further improvements to steam engines which, by 1782, made them even more efficient and convenient to use. In 1783, the first working paddle wheel steamboat chugged down a French waterway, and by 1792, charcoal was providing gas for lamps which lit the streets of Cornwall. Now goods and people could travel faster, while working and shopping later into the evening.

By 1800, high pressure engines were providing five times the pressure that Watt's engines ever could. In Italy, Allessandro Volta produced the first electricity from a wet-cell battery. By 1821, Englishman Michael Farraday had invented the first electric motor. Electromagnets soon followed, and by 1831 American engineers had produced one which could lift 2,086 pounds! The French by now were running the first practical water turbines, used, of course, to drive machinery. By the end of the 19th century, these Fossil Fuels Power Progress

The hunger for coal increased as more factories popped up in Britain, Germany, France and the United States. Soon came more inventions to extract and remove coal faster. In 1859, the first oil well was drilled in the United States. The following year, in Belgium, the first internal combustion engine, predecessor of the automobile engine, burned gas for fuel. Ironically, around the same time, the world's first solar engine was patented, using mirrors to focus heat onto a boiler to make steam for steam engines. This and other inventions which used "cleaner" energy sources seemed to be lost in the surge of progress when, a year later in 1862, the French perfected the four-stroke internal combustion engine. Now power could really be made mobile.

By 1885, the German Karl Benz had produced the first gas-driven, three-wheeled motor car, soon followed by the four-wheeled design of Gottleib Daimler in 1887. Quickly two French designers turned out the first prototype of a modern car, while Michelin, another Frenchman, developed the first tires which contained air. These were much easier to make and use than the original solid rubber tires.

An Electric Way of Life

In Britain, Charles Parsons built the first practical steam turbine used for the generation of electricity, while, in 1879, the prolific Tom Edison perfected his electric light bulb. Soon after, Edison designed the firstlamp commercial electric generation station, burning coal to produce the steam needed for turbine generators.

In 1897, Parsons installed his steam engine in his boat, Turbinia, and outran every ship in the water - even the huge three-masted clippers, the fastest ships in those days. Soon steam-driven ships were dotting the waterways, while on land the taste for "clean," convenient electric lighting was increasing. By 1891 the world's first hydroelectric power stations were built simultaneously - one near Frankfurt, Germany, and the other at Niagara Falls, U.S. At that time, no one could foresee that hydropower would later provide one fourth of the world's electricity.

The turn of the century ushered in even more changes, starting with the drilling of the first offshore oil well off the coast of California. This was soon followed by the first cheap, mass-produced car, the Model T, which rolled off of Henry Ford's production lines in 1908. At the same time, the first geothermal power plant started churning out electricity in Italy, and Einstein published his revolutionary theory that mass can be converted to energy (later important in the discovery of nuclear fission power). The power of wind was soon harnessed for electricity in the 1920s when an electric generator windmill began operating in the U.S., and advanced "egg-beater" windmill designs were tested successfully in France. Cheap oil and gas, however, believed plentiful at this time, continued to dominate the power scene.

Then came the development of nuclear power. Otto Hahn, a German chemist, discovered, in 1939, the process of nuclear fission (releasing energy by splitting uranium atoms). Soon, in 1942, Enrico Fermi, an Italian physicist working in the United States, designed and built the first nuclear fission reactor in Chicago. By 1954, the first nuclear-powered electricity station had opened in the U.S.S.R., while in the same year, Bell Telegraph Laboratories in the U.S. began using solar cells for electric generation. Even so, fossil fuel use still took the lead, and by 1983, three out of every four power plants in the United States burned fossil fuels. At the same time, almost every household either owned a car or used fossil fuel-powered public transportation.

In spite of the development of cleaner alternative energy sources, the United States continues to have a tremendous hunger for and dependence on fossil fuels - resources that are limited, often purchased from (sometimes unfriendly) foreign countries, and environmentally unsafe.

 
 

Electricity...courtesy of mother nature.

In the United States, we use lots of watts...of electricity, that is. Much of this electricity is made by burning fossil fuels that are dirty and irreplaceable. Fortunately, there are alternatives. Here are some of the big players in the sustainable energy marketplace.

GEOTHERMAL - From the first power plant in Larderello, Italy, to the state-of-the-art facilities found all over the world today, geothermal plants use natural hot water and steam from the earth to run turbine generators. Technological advances are making this a cost-effective resource. Expect to see its increased use in the near future, especially in the geothermally active western United States, Indonesia, and other "hot spots" around the Pacific.

HYDRO - Turbine electricity generators can do their work without steam by using the force of falling water. For centuries water has been turning water wheels and even water clocks (used 2000 years ago in the great Library of Alexandria). Today, the force of falling water, hydropower, produces more electricity than any other "alternative" resource.

BIOMASS - Electricity can be generated by burning organic wastes as fuel to heat water for steam. The most common form of biomass is wood; however, today's biomass resources also include agricultural and municipal solid wastes and landfill gases.

WIND - The Persians had the right idea. They figured out how to use wind to turn mills to lift water for irrigation in vast windy Persian plains. Since that time, all over the world, windmills have been grinding grain, pumping water, charging batteries and now, since the 1940's, producing electricity.

SOLAR - The brilliant rays of the sun have benefited our planet for millions of years. As of the 1970's we have perfected methods to concentrate those rays in order to convert them into electricity. At a solar thermal plant, the sun's rays are focused by large mirrors onto a large water tank creating steam for power generation.
