Are you looking for means that are profitable? Have you thought about taking some of your money and invest it in alternative energy? By the year 2013, green energy production is expected to be in the multi-billion dollar range. Wind energy has become extremely economical because of better technology and increasing widespread use. This wind energy technology, which is more state-of-the-art, have become more competitive, market-wise, with conventional types of energy. Not even birds are getting killed anymore with the innovative wind-powered technology.
Your investment dollars may be spent in other worse places than in companies that are engaged in wind energy production. One other alternative energy resource you may invest in is solar cell technology. You wil lbe able to find these in private property lights, calculators, buoys used by the US Coast Guard, and a lot of other places. Solar cells are being used on more and more roofs of commercial buildings, and also housing developments and building complexes. As the cost to use these solar batteries continue to fall, the energy efficiency continues to improve. This is computed by the amount of work required for producing energy, compared to the energy generated.
The conversion efficiency of silicon cells was 4% in 1982, but nowadays it is over 20 percent. Solar sells does not produce any pollution when creating electricity but it is not cost-effective enough to replace traditional electricity. These cells, because of space constraints, are not able to generate industrial-production amounts of electricity. There are more available areas where these photovoltaic cells can be put, and the efficiency is rising while the costs keep going down. As the research and development of alternative energy grow, advisors who manage investments continue to recommend people to invest in it.
New forms of clean energy are emerging from tidal movement, currents, and differences in temperature. Hydro power generation is advancing with the French, and being studied by experts in Scotland and America. Hydro-power has had issues before with salt water causing the deterioration of metal but the materials employed these days are more efficient. Also in the past, very violent storms and unusual marine growth also caused problems in using hydro-power effectively. As the timing of ocean waves and currents is so reliable, as well as understood, there is a great advantage to ocean-produced energy.
Investments in hydro-electric technology have increased a good deal over the past few decades. The power it generates is clean but hydro-electric energy is limited by geography. Older dams, for instance, have had issues with marine life disruption. There has been a lot of effort to protect the marine life but the cost has been high. Because of this, low-impact hydro-energy generators without ecological problems, have been given more attention. After all's said and done, investing in green, alternative energy is the way to go.
