Are you looking for places to invest your money that will bring you profits? A smart investment to seriously consider is alternative energy. It is expected that alternative energy production will be in the billion dollar range by 2013. Wind energy has become really affordable due to better technology and increasing widespread use. This has resulted in wind technology being very competitive against more established types of energy producing products. As a matter of fact, wind-produced energy is advanced where birds no longer being killed by the propellers.
You wouldn't want invest your hard-earned money into something that doesn't help the environment. Another area to consider investing dollars in is photovoltaic cell technology. These solar cells can be found in small lights, hand calculators, buoys used by the US Coast Guard and other devices. They are being utilized on an increasing number of roofs of commercial buildings, as well as housing developments and building complexes. As prices keep decreasing, the efficiency of solar arrays continues to increase. This is computed by the amount of work needed for generating energy, compared to the energy produced.
Back in 1982, the silicon cells' conversion efficiency was roughly 4% but today, it is over 20%. When generating electrical power, solar cells do not produce any pollution, but right now they are not cost-effective with regular electricity. Since large amounts of cells are called for to create large amounts of electricity, they are not ready for producing electricity on a large scale. But as areas are converted to install these cells, the cost and efficiency will keep on improving. With the continual search for new ways of generating alternative energy, advisors of investment portfolios are confident that energy is a good investment.
There are new areas for new green energy that are appearing like employing currents, tidal movements and temperature. Utilizing hydro-power is advancing well in France and being researched in Scotland and America. Hydro-power has had problems before with salt water causing the deterioration of metal but the materials used these days are better. Severe storms and marine growth have likewise been disruptions to the production of energy years ago. Since the timing of ocean waves and currents can be relied on, as well as understood, there is a great advantage to ocean-produced energy.
Investments in hydro-electric technology have gone up a good deal over the past several decades. The power it generates is clean but hydro-electric power is restricted by geography. Older dams, for example, have had issues with marine life disruption. There has been a lot of effort to protect the marine life but it's been costly. As a result, low-impact hydro-power plants that doesn't cause ecological problems, have been given more attention. The reality of all of this information is that putting your money in the future of green energy is good advice.
