Are you in search of places to invest your money that will turn out to be profitable? Why not take some of your money and put it into alternative energy sources? By the year 2013, green energy production is predicted to be in the multi-billion dollar range. wind power has become more economical with the advancement in wind-turbine technologies and more widespread in usage too. This has resulted in wind technology being very competitive against more conventional kinds of energy producing products. As a matter of fact, wind-produced energy is advanced where birds no longer get killed by the propellers.
You can put your money in companies that do a lot worse than wind energy production. Another area to look into are solar cell investments, or solar cell technology. These little solar-powered cells are powering things like calculators, flashlights, and other gizmos. They are being used on an increasing number of roofs of commercial buildings, and also housing developments and building complexes. Along with the falling prices, their energy efficiency is constantly increasing. This efficiency is estmitaged by the amount of energy necessary to produce versus the amount of energy created.
Back in 1982, the silicon cells' conversion efficiency was roughly 4% but these days, it is over 20%. Photovoltaic cells does not produce any pollution when producing electricity but it is not inexpensive enough to replace traditional electricity. These solar cells, as a result of space constraints, are not able to produce industrial-production amounts of electricity. However, the price and efficiency will continue improving as the use of these cells continue to grow. With the nonstop search for new ways of producing alternative energy, advisors of investment portfolios are certain that energy is a good investment.
New kinds of green energy are emerging such as tidal movements, currents and temperature changes. The concept of hydro-power generation is advancing in France and being widely researched in Scotland and America. Salt water has been a problem previously with metal deterioration, but that has been improved by using better materials. Violent storms and marine growth have likewise been disruptions to the production of energy previously. However, we know that the timing of ocean waves and currents is really consistent thus making it a reliable source for energy.
Investments in hydro-electric technology have gone up a great deal over the past several decades. Hydro-electric energy produces really clean energy but it is confined by location. Older dams have had problems with marine life disrupting production of energy. There has been great effort to protect the marine life but it's been expected. As a result of this, low-impact hydro-power generators with no ecological problems, have been given more attention. The reality of all of this information is that investing your dollars in the future of eco-friendly energy is a smart thing to do.
