Investments in Alternative Energy
It is possible to have a portfolio which profitably (thats the key word، is it not?) invests in alternative energy funds. ?Green? energy production is expected to be a multi-billion (in todays dollars) industry by 2013.
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 dont 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
