Analysts predict that by 2013, the alternative energy industry will be a $13 billion dollar industry in today’s dollars. This figure bespeaks an enormous return on investment. Indeed, if you were to invest in a start-up alternative energy company, you might find yourself having invested in the next Microsoft in terms of return on investment. People are fed up with the rising costs of gasoline—while this alone is not sufficient understanding of the need for developing alternative energy sources, it is a factor which can act as a market maker—meaning for you that investments in alternative energy companies makes a lot of financial sense.

However, this does not mean that you don’t first want to do some careful research into alternative energy stocks, perhaps with the help of a financial planner. “A few alternative-energy companies are going after the right markets but that doesn’t mean you should go buy every name in the sector. Investors need to be cautious about chasing the stocks,” says Sanjay Shrestha, who is an analyst at First Albany Capital. And if you are an investor, then you know that the problem in this sector is that nearly every single one of the major players in the alternative energy for profit game are start-ups or in the very early stages of growth. This means for you that they have relatively minuscule (even if rapidly growing) sales, and no expected profitability in the near term or history of earnings for you to be able to research. This can lead to some bubbling, as with what happened to the dot-com industry at the turn of the 21st century. Bubbling in the stock market is not a good thing for investors.

Ananlysts and financial planners can play a crucial role in helping you get it right with alternative energy investing. “We don’t play around in the tiny cap stocks that have technology and not much revenue—the ‘hope’ stocks. We invest in companies with clear cash-generation plans in place,” are the words of Ben walker, who is a senior portfolio manager at the Gartmore Global Utilities fund out of London.

Still, the outlook is very positive overall—and healthy. “It is good to see that the number of renewable energy funds and the amount of money flowing into these funds is increasing,” according to chief executive of UK alternative elecricity supplier Good Energy Juliet Davenport. “The renewable generation market is at an important stage in its development; it needs the continued support of the consumer, investor and government to ensure that it reaches its potential and really starts to make a difference to climate change.”

The US and its citizenry need to invest all of the time and energy that they can spare to the conversion from a fossil fuel burning society to one that is green for several different reasons. The green economy will not harm the environment or the quality of our air like fossil fuel burning does. We can become the energy independent nation that we need to be by cutting away our need to import oil, especially oil that is produced by anti-American nations such as Iran.  Ultimately, renewable energies and extremely efficient energies like atomic energy are far less expensive than the continuous mining and drilling for fossil fuels.  If we do not invest in our future now, catastrophe awaits us. We are going to need to consume more energy than ever in our history as we sail into the 21st century and beyond—our dependency on foreigners for meeting these energy needs only leaves us open to sabotage while draining our coffers in order to fill other nations’.

It can be argued that federal, state, and local governments should work in conjunction on the issue of alternative energy research and development and implement mandatory programs for new home construction and all home remodeling that stipulate the installation of alternative energy power sources—eventually over a certain period of years transforming into 100% installation of alternative energy sources for any new home or corporate building—as well as backing a similar program to have all new vehicles produced in the nation be hybrid vehicles or hydrogen fuel cell powered vehicles by the year 2020. All levels of government could also impose mandatory compliance laws on construction and utilities companies. The utility companies in all 50 states should be required to invest in alternative energy research and development while also being required to buy back, at fair rates, excess energy produced by homeowners through their use of alternative energy power sources. Strong financial incentives need to be in place for new companies to invest in developing renewable energies. This would not only make the US energy independent at the fastest possible rate, but it would stimulate the growth of the economy and provide tens of thousands of new, good-paying jobs for people.

Alternative energy generation in the forms of solar, wind, hydroelectric, biofuel, geothermal, and atomic; alternative energy storage systems such as more efficient batteris and hydrogen fuel cells; and alternative energy-furthering infrastructures with superior energy efficiency all need to be brought into the affordable price range through development. Government investment into these matters would surely help us along.

Positions in the alternative energy research and development industry often offer just such an opportunity.

The alternative energy field is in need of a vast array of different positions. Many people who get into this are the kind who would keep the power plants up and running (these include plant operators or mechanics), others are the developers of new alternative energies (engineers, scientists), and others make it all happen to start with by investing in alternative energy. So–not only do these people have the blessing of an exciting and fulfilling career, but these same people are making the world a better place.

The business of alternative energy is rapidly growing due to the fact that many governments are now supporting it. Investors have become excited about putting their financial backing into the alternative energy industry because they can see that it’s the wave of the future, out of both need and the fact of government support. Rising oil prices make alternative energies’ tantalization rise in the minds of investors. As investors become more interested, there is more money available for companies to start up or expand, and that leads (of course) to more job opportunities.

The US government is unquestionably involved in promoting the idea of new jobs as being readily available in the alternative energy sector. According to the President,  in order to achieve greater use of “homegrown”,  renewable fuels in the United States, advanced technologies need to be researched  and  developed so as to be able to make ethanol from plant fibers’ biomass, which at the present time is merely discarded as waste material. The President’s 2007 Federal Budget includes $150 million (a $59 million increase over the Federal Budget for 2006) to help with the development of biofuels derived from agricultural waste products such as wood chips, corn stalks, and switch grass. Researchers tell us that furthering the cause of research into cellulose-based ethanol could make the technology cost-competitive by 2012, while potentially displacing up to 30% of the nation’s current fuel consumption.

The President’s plan would additionally drive on next-generation research and development of battery technology for hybrid vehicles in addition to “plug-in hybrid” vehicles. A “plug-in” hybrid runs on either  gasoline or electricity, depending upon an on-board computer calculation. Driving in a city setting consumes almost no gasoline over as much as a week’s time with these vehicles.

The most recently developed wind-turbine technologies have brought us wind-produced energy which is more cost efficient as well as more widespread. More state-of-the-art wind energy technologies are typically more market competitive with conventional energy technologies. The newer wind-power technologies don’t even kill birds like in days of old! Wind energy production is a growing technology, and companies engaged in it would make up an excellent part of a growth or aggressive growth portfolio.

Next to consider are solar cell, or photovoltaic cell, technologies. These are to be found implemented in pocket calculators, private property lights, US Coast Guard buoys, and other areas. More and more they find their way onto the roofs of housing and commercial buildings and building complexes. Cost is falling. Their energy efficiency (the ratio of the amount of work needed to cause their energy production versus the actual energy production) is steadily on the rise. As an example, the conversion efficiency of silicon cells has increased from a mere four percent in 1982 to over 20% for the latest technologies. Photovoltaic cells create absolute zero pollution as they are generating electrical power. However, photovoltaic cellls are not presently as cost effective as “utility produced” electricity. “PV” cells are not [capable at present for producing industrial-production amounts of electricity due to their present constraints on space. However, areas where photovoltaic cell arrays could be implemented are increasingly available. In sum, costs are going down while efficiency is rising for this alternative fuel technology.

Many alternative energy investment portfolio advisors are confident that alternative energies derived from currents, tidal movement, and temperature differentials are poised to become a new and predominant form of clean energy. The French are actually fairly advanced at hydro power generation, and numerous studies are being made in Scotland and the US along these sames lines. Some concerns  center around the problems with the deterioration of metals in salt water, marine growth such as barnacles, and violent storms which have all been disruptions to energy production in the past. However, these problems for the most part seem to be cured through the use of different, better materials. Ocean-produced energy has a huge advantage because the timing of ocean currents and waves are well understood and reliable.

Investments in hydro-electric technology have grown in the last two decades. Hydro-electric power is clean; however, it’s also limited by geography. While already prominent as power generation, the large, older dams have had problems with disturbing marine life. Improvements have been made on those dams in order to protect marine life, but these improvements have been expensive. Consequently, more attention is now being paid to low-impact “run-of-the-river” hydro-power plants, which do not have these ecological problems.

The reality is, the energy future is green, and investors would do well to put their money out wisely, with that advice in their minds.

We must also switch to alternative forms of energy because our present forms are too damaging to the atmosphere. While this write does not believe that the global warming trend is much, if at all, sustained by the activities of mankind (in short, it’s a natural cycle and there’s nothing we can do about it except prepare for the effects of it), we certainly do contribute at present to the destruction of the environment and to things like air pollution with our energy sources as they are. Coal is another source of energy that we need to wean ourselves off of—again, it is finite, and it is filthy, and the mining of it is dangerous and environmentally disruptive. We can also explore new, streamlined methods for producing electricity that we presently generate so much of via hydro-power so that we are less disruptive of the environment when we have need of constructing things such as large dams.

Developing nations which have turned industrialized in recent decades especially will need the benefits of alternative energy research and development, for they are presently doing much more environmental damage than the United States. The United States, Japan, and some European nations have been implementing studies into and programs for the development of alternative energy sources, and are therefore already leading the way in doing less environmental damage. The developing nations such as China and India need to look to Japan and the West as examples of what research and development to give government backing and private investment currency to. We could also add great robustness to our own economy by being at the forefront of such alternative energy sources development and then marketing the technologies and services to nations like India, China, Brazil, and so on and so forth.

Biofuels from things like “supertrees” and soybeans, refined hydroelectric technology, natural gas, hydrogen fuel cells, the further building of atomic energy plants, the continued development of solar energy photovoltaic cells, more research into wind-harnessed power—all of these are viable energy sources that can act as alternatives to the mammoth amounts of oil and coal that we presently are so dependent on for our very lifestyles. The energy of the future is green.

Wind energy has become the most-invested-in (by private investors and governments together) alternative energy source for the time being. The great arrays of triple-bladed windmills are being placed all over as “wind farms”, to capture the motion of the wind and use its kinetic energy for conversion to mechanical or electrical energy. Of course, there is nothing new about the concept of a windmill for harnessing energy. Modern wind turbines are simply are more advanced variations on the old theme. Of course, the drawback to wind energy is…what do you do when there is a calm, still day? Needless to say, during these times the electric company kicks in for powering your home or office. Wind energy is not altogether independent.

Hydroelectric energy is available as a source of alternative energy, and it can generate a substantial amount of power. Simply put, hydroelectric energy uses the motion of water—its flow in response to gravity, which means downhill—to turn turbines which then generate electrical energy. Needless to say, water is ubiquitous; finding sources for driving hydroelectric turbines is, therefore, not much of a problem. However, hydroelectricity as a source of alternative energy can be complicated and expensive to produce. Dams are often built in order to be able to control the flow of the water sufficiently to generate the needed power. Building a dam to store and control water’s potential and kinetic energy takes quite a lot of work, and operating one is complex as well,and conservationists grow concerned that it. Of course, a dam is not always needed if one is not trying to supply the electrical needs of a city or other very densely populated area. There are small run-of-river hydroelectric converters which are good for supplying neighborhoods or an individual office or home.

Probably the most underrated and under-appreciated form of alternative energy is geothermal energy, which is simply the naturally-occurring energy produced by the heating of artesian waters that are just below the earth’s crust. This heat is transferred into the water from the earth’s inner molten core. The water is drawn up by various different methods—there are “dry steam” power plants, “flash” power plants, and “binary” power plants for harnessing geothermal energy. The purpose of drawing up the hot water is for the gathering of the steam.  The Geysers, approximately 100 miles north of San Francisco, is probably the best-known of all geothermal power fields; it’s an example of a dry stream plant.

Over in the US, the BP corporation has established an Energy Biosciences Institute (EBI) to spearhead extensive new research and development efforts into clean burning renewable energy sources, most prominently biofuels for ground vehicles. BP’s investment comes to $50 million (US) per year over the course of the next decade. This EBI will be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for research and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to produce renewable fuels in liquid form for automobile consumption. The University will especially spearhead efforts in the field of genetic engineering with regard to creating the more advanced biofuel crops. The EBI will additionally have as a major focal point technological innovations for converting heavy hydrocarbons into pollution-free and highly efficient fuels.

Also in the US, the battle rages on between Congress and the Geothermal Energy Association (GEA). The GEA’s Executive Director Karl Gawell has recently written to the Congress and the Department of Energy, the only way to ensure that DOE and OMB do not simply revert to their irrational insistence on terminating the geothermal research program is to schedule a congressional hearing specifically on geothermal energy, its potential, and the role of federal research. Furthermore, Gawell goes on to say that recent studies by the National Research Council, the Western Governors’ Association Clean Energy Task Force and the Massachusetts Institute of Technology all support expanding geothermal research funding to develop the technology necessary to utilize this vast, untapped domestic renewable energy resource. Supporters of geothermal energy, such as this writer, are amazed at the minuscule amount of awareness that the public has about the huge benefits that research and development of the renewable alternative energy source would provide the US, both practically and economically. Geothermal energy is already less expensive to produce in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal energy is readily available, sitting just a few miles below our feet and easily accessible through drilling. One company, Ormat, which is the third largest geothermal energy producer in the US and has plants in several different nations, is already a billion-dollar-per-year business—geothermal energy is certainly economically viable.

Solar powered electricity generation is certainly good for the environment, as this alternative form of producing energy gives off absolutely zero emissions into the atmosphere and is merely utilizing one of the most naturally occurring of all things as its driver. Solar collection cells are becoming slowly but surely ever more practical for placing upon the rooftops of people’s homes, and they are not a difficult system to use for heating one’s home, creating hot water, or producing electricity. In the case of using the photovoltaic cells for hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through your pipes.

Photovoltaic cells are becoming increasingly better at collecting sufficient radiation from the sun even on overcast or stormy days. One company in particular, Uni-Solar, has developed solar collection arrays for the home that work well on inclement days, by way of a technologically more advanced system that stores more energy at one time during sunlit days than previous or other arrays.

There is actually another solar power system available for use called the PV System. The PV System is connected to the nearest electrical grid; whenever there is an excess of solar energy being collected at a particular home, it is transferred to the grid for shared use and as a means of lowering the grid’s dependence on the hydroelectrically-driven electricity production. Being connected to the PV System can keep your costs down as compared to full-fledged solar energy, while at once reducing pollution and taking pressure off the grid system. Some areas are designing centralized solar collection arrays for small towns or suburban communities.

Some big-name corporations have made it clear that they are also getting into the act of using solar power (a further indication that solar generated energy is becoming an economically viable alternative energy source). Google is putting in a  1.6 megawatt solar power generation plant on the roof of its corporate headquarters, while Wal Mart wants to put in an enormous 100 megawatt system of its own.

Nations such as Japan, Germany, the United States, and Switzerland have been furthering the cause of solar energy production by providing government subsidies or by giving tax breaks to companies and individuals who agree to utilize solar power for generating their heat or electrical power. As technology advances and a greater storage of solar collection materials is made available, more and more private investors will see the value of investing in this “green” technology and further its implementation much more.

Environmental Power is an alternative energy supplier that has two subsidiary companies. One of these is Microgy, which is Environmental Power’s research and development arm. Microgy is a developer of biogas facilities for the cost-effective and environmentally clean production of renewable energy derived from food and agricultural waste products. These biogas fuels can be used in a number of different applications. They can be used in combustion chamber engines, used directly to make fossil fuel reliance less of a need, or cleaned up to meet natural gas standards and then piped to offices or homes for heating. Environmental Power’s other subsidiary is Buzzard Power. Buzzard has an 83 megawatt power facility which generates green energy from mined coal waste. Environmental Power says of itself, we have a long and successful history of developing clean energy facilities. Since 1982 we have developed, owned and operated hydroelectric plants, municipal waste projects, coal-fired generating facilities and clean gas generation and energy recovery facilities. We are proud to have a management team and board of directors comprised of leaders from both the public and private sectors, including the energy, agriculture and finance industries.

Intrepid Technology and Resources, Inc, is a company that processes waste into natural gas as an alternative source of energy. The company’s vision centers on the fact that the US produces two billion tons of animal waste every year, while at once the US’ supply of natural gas is dwindling. ITR builds “organic waste digesters” local to sites of organic waste. These facilities produce, clean, and distribute the methane gas from the organic waste; methane gas is a viable alternative to natural gas. ITR is presently operating in Idaho with plans for national expansion.

Nathaniel Energy is a company with the objective of protecting the environment and minimizing total cost of business ownership. The Nathaniel Energy Total Value Preservation System (TVPS) gives companies unique benefits through Nathaniel’s recognition of the alternative energy potential of materials that are  usually seen as nothing more than waste or pollutants. Nathaniel Energy’s technology allows it to extract and  transform into alternative energy virtually all of the potential energy locked in waste materials. All of this is produced at almost no additional cost beyond what a company would have had to spend in order to install pollution control and prevention systems. Nathaniel Energy’s innovative TVPS recovers valuable resources which other processes fail to. Throughout the entire process, the maximum amount of valuable material is recovered for reuse, which results in lowered costs and environmental protection. Usual pollution cleanup and control processes treat these materials as mere contaminants that are either destroyed or discarded. The TVPS therefore decreases the total cost of business ownership through the provision of an additional stream of income.

The US military is very interested in certain alternative energies that, with the right research and development technologically, can make it energy independent, or at least a great deal more so, on the battlefield. One of the things that greatly interests the military along these lines is the development of small nuclear reactors, which could be portable, for producing theater-local electricity. The military is impressed with how clean-burning nuclear reactors are and how energy efficient they are. Making them portable for the typical warfare of today’s highly mobile, small-scaled military operations is something they are researching. The most prominent thing that the US military thinks these small nuclear reactors would be useful for involves the removal of hydrogen (for fuel cell) from seawater. It also thinks that converting seawater to hydrogen fuel in this way would have less negative impact on the environment than its current practices of remaining supplied out in the field.

Seawater is, in fact, the military’s highest interest when it comes to the matter of alternative energy supply. Seawater can be endlessly “mined” for hydrogen, which in turn powers advanced fuel cells. Using OTEC, seawater can also be endlessly converted into desalinated, potable water.  Potable water and hydrogen for power are two of the things that a near-future deployed military force will need most of all.

In the cores of nuclear reactors—which as stated above are devices highly interesting, in portable form, to the US military—we encounter temperatures greater than 1000 degrees Celsius. When this level of temperature is mixed with a thermo-chemical water-splitting procedure, we have on our hands the most efficient means of breaking down water into its component parts, which are molecular hydrogen and oxygen. The minerals and salts that are contained in seawater would have to be extracted via a desalination process in order to make the way clear for the water-splitting process. These could then be utilized, such as in vitamins or in salt shakers, or simply sent back to the ocean (recycling). Using the power of nuclear reactors to extract this hydrogen from the sea, in order to then input that into fuel cells to power advanced airplanes, tanks, ground vehicles, and the like, is clearly high on the R & D priority list of the military.
